Innovate from cloud to edge on your terms with Azure

Azure Exam Prep, Azure Tutorial and Material, Azure Preparation, Azure Study Material

The challenges of the past year revealed that serving and making a difference for each other, our communities, and the world around us is more critical than ever. In order to persevere and drive business success, organizations must be future-ready, build on their terms, operate hybrid seamlessly, and do all of this with an uncompromising foundation of trust. Microsoft Azure is committed to helping every organization accomplish just that, as outlined by our announcements at this week’s Microsoft Inspire.

Expand opportunities with new Azure infrastructure capabilities

Over 95 percent of Fortune 500 companies are transforming their businesses using Azure, relying on an enterprise-grade infrastructure and deep integration with the rest of the Microsoft Cloud. Azure is designed to power all workloads—providing the best Windows 10 (and now Windows 11) virtual experience for Virtual Desktop Infrastructure (VDI), offering the lowest total cost of ownership for Windows Server and SQL workloads, growing Linux workloads, and open source databases (over half of all Azure VMs are running Linux), and supporting specialized workloads such as SAP, VMware, high-performance computing (HPC), and more.

For Windows Server and SQL Server workloads, customers can take advantage of Azure Hybrid Benefit and—announced today—three years of free Extended Security Updates for Windows Server 2012/R2 and SQL Server 2012 running on Azure.

For all these workloads, cloud migration can be a huge project. We are committed to simplifying the journey, ensuring customers receive tailored support. We’ve expanded our Azure Migration and Modernization Program offering new scenarios that support the modernization of any app, regardless of framework or supporting database, into a broad array of managed services including Azure App Service, Azure Kubernetes Service, and—starting today—Azure Spring Cloud and Azure Cosmos DB. 

Bring innovation anywhere with Azure’s hybrid and multicloud approach

Taking a hybrid and multicloud approach resonates with how our customers view their businesses. Azure Arc is key to our approach to helping customers operate hybrid seamlessly. Enabled by Azure Arc, customers can also bring Azure services to any existing infrastructure including other clouds to take advantage of Azure’s benefits anywhere. This includes running managed databases like Azure SQL and Azure PostgreSQL on the infrastructure of your choice, as well as extending machine learning to the edge in order to run models close to where the data lives.

Azure Arc also integrates with Azure Lighthouse so partners can manage multiple customers resources across the edge, datacenters, and multicloud environments. With the general availability of Azure SQL enabled by Azure Arc on July 30, 2021, managed service providers using Azure Lighthouse will be able to manage cloud data services (alongside Windows, Linux, and Kubernetes) on any on-premises infrastructure or in any cloud environment a customer needs without having to change existing tools or processes.

Azure Stack HCI helps customers modernize datacenters with a hybrid solution of hyperconverged infrastructure tightly integrated with Azure. New for Azure Stack HCI, it is now possible to simplify guest licensing activation with Automatic Virtual Machine Activation (AVMA), and with a secured-core server, customers benefit from advanced protection with defense-in-depth protection over multiple layers across hardware, firmware, and operating systems. We also are happy to announce a new partner program to validate ISV software and SI services for the Azure Stack family with promotional activities for the partner solutions. To learn more, contact the Azure Stack Partner Program. In addition, the new advanced specializations for partners for Azure Stack HCI and Azure Arc are available for eligible partners to get advanced training and certification.

Innovate with Azure data

Our commitment to developers is to make Azure the best cloud for developing intelligent cloud-native applications that harness the power of data and AI.

Azure Exam Prep, Azure Tutorial and Material, Azure Preparation, Azure Study Material
We recently announced several updates to Azure Cosmos DB that enhance its performance even further and help empower developers and ISVs to innovate with Azure Cosmos DB. Azure Cosmos DB serverless charges only for resources consumed and is great for applications with spiky traffic patterns. Azure Cosmos DB integrated cache reduces costs by up to 96 percent and boosts performance by up to 300 percent for read-heavy workloads. Always Encrypted for Azure Cosmos DB enables client-side encryption of sensitive data prior to being stored in a database. Azure Cosmos DB role-based access control (RBAC) enables admins to create Azure Active Directory roles with specific database access permissions.

We’ve also enhanced the developer experience on Azure Cosmos DB by introducing a significant expansion to Azure Cosmos DB’s free tier. Application developers will now have more flexibility to innovate at no cost with 1,000 RU/s provisioned throughput and 25 GB storage free monthly.

With these enhancements to Azure Cosmos DB, it’s easier and more cost-effective than ever to build new cloud-native applications on Azure. And when developers pair the globally available serverless Azure Cosmos DB with the highly elastic serverless Azure Functions, they get a unique combination that solves complex orchestration problems and enables mission-critical, even-driven modern applications.

Go limitless with Azure Analytics

Capturing the operational data in a cloud-native application with Azure Cosmos DB is just the beginning. Customers gain near-real-time insights on that data with a single click using Azure Synapse Link for Azure Cosmos DB. This low-cost, cloud-native HTAP implementation enables organizations to bring in-the-moment analytics to their business, with no ETL required and no performance impact on their operational system.

In order to meet our commitment to make analytics in Azure the most performant and secure experience it can be, we have continued to innovate with Azure Synapse Analytics. We recently announced several new capabilities and offers to help accelerate adoption, including Azure Synapse Pathway, which significantly accelerates data warehouse migrations by automating SQL code conversion to Azure Synapse. New Azure Synapse Business Value Assessments help partners drive value conversations with customers considering modernizing their analytics solution. The Azure Synapse migration offer boosts cost savings for customers migrating on-premises data warehouses to Azure Synapse, on top of the existing reserved capacity discounts. And the Azure Synapse limited-time free quantities offer enables customers with qualifying subscription types to take advantage of serverless capabilities and enjoy up to 10 TB of free queries per month, as well as the optimized Apache Spark capabilities for big data workloads with up to 120 free vCore-hours per month.

Discover and govern better than ever with comprehensive data governance

With the exponential growth in the volume, type, source, and interconnectedness of data, the need has never been greater to discover and govern that data across the organization. Azure Purview is a unified data management and governance solution that helps organizations achieve a complete understanding of their data. It helps discover, classify, protect, and govern data wherever it resides: on-premises, across clouds (including support for Amazon Web Services S3), in SaaS applications, and in Microsoft Power BI.

Advancing global network reliability through intelligent software - Part 2

Read Advancing global network reliability through intelligent software part 1.

In part one of this networking post, we presented the key design principles of our global network, explored how we emulate changes, our zero touch operations and change automation, and capacity planning. In part two, we start with traffic management. For a large-scale network like ours, it would not be efficient to use traditional hardware managed traffic routing. Instead, we have developed several software-based solutions to intelligently manage traffic engineering in our global network.

SDN-based Internet Traffic Engineering (ITE)

The edge is the most dynamic part of the global network—because the edge is how users connect to Microsoft’s services. We have strategically deployed edge PoPs close to users, to improve customer/network latency and extend the reach of Microsoft cloud services.

Read More: MS-900: Microsoft 365 Fundamentals

For example, if a user in Sydney, Australia accesses Azure resources hosted in Chicago, USA their traffic enters the Microsoft network at an edge PoP in Sydney then travels on our network to the service hosted in Chicago. The return traffic from Azure in Chicago flows back to Sydney on our Microsoft network. By accepting and delivering the traffic to the point closest to the user, we can better control the performance.

Azure Exam Prep, Azure Tutorial and Materials, Azure Preparation, Azure Learning, Azure Guides, Azure Career

Each edge PoP is connected to tens or hundreds of peering networks. Routes between our network and providers’ networks are exchanged using the Border Gateway Protocol (BGP). BGP best path selection has no inherent concept of congestion or performance—neither is BGP capacity aware. So, we developed an SDN-based Internet Traffic Engineering (ITE) system that steers traffic at the edge. The entry and exit points are dynamically altered based on the traffic load of the edge, internet partners’ capacity constraints, reduction or augments in capacity, demand spikes sometimes caused by distributed denial of service attacks, and latency performance of our internet partners. The ITE controller constantly monitors these signals and alters the routes we advertise to our internet partners and/or the routes advertised inside the Microsoft network, to select the best peer-edge.

Optimizing last mile resilience with Azure Peering Service


In addition to optimizing routes within our global network, the Azure Peering Service extends the optimized connectivity to the last mile in the networks of Internet Service Providers (ISPs). Azure Peering Service is a collaboration platform with providers, to enable reliable high-performing connectivity from the users to the Microsoft network. The partnership ensures local and geo redundancy, and proximity to the end users. Each peering location is provisioned with redundant and diverse peering links. Also, providers interconnect at multiple Microsoft PoP locations so that if one of the edge nodes has degraded performance, the traffic routes to and from Microsoft via alternative sites. Internet performance telemetries from Map of Internet (MOI) drive traffic steering for optimized last mile performance.

Route Anomaly Detection and Remediation (RADAR)


The internet runs on BGP. A network or autonomous system is bound to trust, accept, and propagate the routes advertised by its peers without questioning its provenance. That is the strength of BGP and allows the internet to update quickly and heal failures. But it is also its weakness—the path to prefixes owned by a network can be changed by accident or malicious intent to redirect, intercept, or blackhole traffic. There are several incidents that happen to every major provider and some make front page news. We developed a global Route Anomaly Detection and Remediation (RADAR) system to protect our global network.

RADAR detects and mitigates Microsoft route hijacks on the Internet. BGP route leak is the propagation of routing announcement(s) beyond their intended scope. RADAR detects route leaks in Azure and the internet. It can identify stable versus unstable versions of a route and validate new announcements. Using RADAR, and the ITE controller, we built real-time protection for Microsoft prefixes. Peering Service platform extends the route monitoring and protection against hijacks, leaks and any other BGP misconfiguration (intended or not) in the last mile up to the customer location.

Software-driven Wide Area Network (SWAN)


The backbone of the global network is analogous to a highway system connecting major cities. The SWAN controller is effectively the navigation system that assigns the routes for each vehicle, such that every vehicle reaches its destination as soon as possible and without causing congestion on the highways. The system consists of topology discovery, demand prediction, path computation, optimization, and route programming.

Azure Exam Prep, Azure Tutorial and Materials, Azure Preparation, Azure Learning, Azure Guides, Azure Career

Over the last 12 months, the speed of the controller to program the network improved by an order of magnitude and the route-finding capability improved two-fold. Link failures are like lane closures so the controller must recompute routes to decrease congestion. The controller uses the same shared risk link groups (SRLGs) to compute backup routes in case of failure of the primary routes. The backup routes activate immediately upon failure, and the controller gets to work at reoptimizing traffic placement. Links that go up and down in rapid succession are held back from service until they stabilize.

One measure of reliability is the percentage of successfully transmitted bytes to requested bytes, measured over an hour and averaged for the day. Ours is 99.999 percent or better for customer workloads. All communication between Microsoft services is through our dedicated global network. Thousand Eyes Cloud Performance Benchmark reports that over 99 percent of Azure inter-region latencies faster than the performance baseline, and over 60 percent of region pairs are at least 10 percent faster. This is a result of the capacity augments and software systems described in this post.

Bandwidth Broker—software-driven Network Quality of Service (QoS)


If the global network is a highway system, Bandwidth Broker is the system that controls the metering lights at the onramps of highways. For every customer vehicle, there is more than one Microsoft vehicle traversing the highway. Some of the Microsoft vehicles are discretionary and can be deferred to avoid congestion for customer vehicles. Customer vehicles always have a free pass to enter the highways. The metering lights are green in normal operation but when there is a failure or a demand spike, Bandwidth Broker turns on the metering lights in a controlled manner. Microsoft internal workloads are divided into traffic tiers, each with a different priority. Higher priority workloads are admitted in preference to lower priority workloads.

Brokering occurs at the sending host. Hosts periodically request bandwidth on behalf of applications running on them. The requests are aggregated by the controller, bandwidth is reserved, and grants are disseminated to each host. Bandwidth Broker and SWAN coordinate to adjust traffic volume to match routes, and traffic routes to match volume.

It is possible to experience multiple fiber cuts or failures that suddenly reduce network capacity. Geo-replication operations to increase resilience can cause a huge surge in network traffic. Bandwidth Broker generally allows us to preserve the customer experience during these conditions, by shedding discretionary internal workloads when congestion was imminent.

Continuous monitoring


A robust monitoring solution is the foundation to achieve higher network reliability. It lowers both the time to detect and time to repair. The monitoring pipelines constantly analyze several telemetry streams including traffic statistics, health signals, logs, and device configurations. The pipelines automatically collect more data when anomalies are detected or diagnose and remediate common failures. These automated interventions are also guarded by safety check systems.

Major investments in monitoring have been:

➤ Polling and ingestion of metrics data at sub-minute speeds. A few samples are needed to filter transients and a few more to generate a strong signal. This leads to faster detection times.
➤ An enhanced diagnostics system that is triggered by packet loss or latency alerts, instructs agents at different vantage points to collect additional information to help triangulate and pinpoint the issue to a specific link or device.
➤ Enhanced diagnostics trigger auto-mitigation and remediation actions for the most common incidents, with the help of Clockwerk and Real Time Operation Checker (ROC). This translates to faster time to repair and has the ripple effect of keeping engineers focused on more complex incidents.

Other pipelines continuously monitor network graphs for node isolation, and periodically assess risks with “what-if” intent using ROC as described above. We have multiple canary agents deployed throughout the network checking reachability, latency, and packet loss across our regions. This includes agents within Azure, as well as outside of our network, to enable outside-in monitoring. We also periodically analyze Map of Internet (MOI) telemetries to measure end to end performance from customers to Azure. Finally, we have robust monitoring in place to protect the network from security attacks such as BGP route hijacks, and distributed denial of service (DDoS).

Next-generation firewall capabilities with Azure Firewall Premium

We are announcing the general availability release of Microsoft Azure Firewall Premium.

Key features in this release include:

1. TLS inspection: Azure Firewall Premium terminates outbound and east-west transport layer security (TLS) connections. Inbound TLS inspection is supported in conjunction with Azure Application Gateway allowing end-to-end encryption. Azure Firewall performs the required value-added security functions and re-encrypts the traffic which is sent to the original destination.

2. IDPS: Azure Firewall Premium provides signature-based intrusion detection and prevention system (IDPS) to allow rapid detection of attacks by looking for specific patterns, such as byte sequences in network traffic or known malicious instruction sequences used by malware.

3. Web categories: Allows administrators to filter outbound user access to the internet based on categories (for example, social networking, search engines, gambling, and so on), reducing the time spent on managing individual fully qualified domain names (FQDNs) and URLs. This capability is also available for Azure Firewall Standard based on FQDNs only.

4. URL filtering: Allow administrators to filter outbound access to specific URLs, not just FQDNs. This capability works for both plain text and encrypted traffic if TLS inspection is enabled.

Azure Firewall Premium benefits

Azure Firewall Premium provides advanced threat protection that meets the needs of highly sensitive and regulated environments, such as the payment and healthcare industries. Organizations can leverage Premium stock-keeping unit (SKU) features like IDPS and TLS inspection to prevent malware and viruses from spreading across networks in both lateral and horizontal directions. To meet the increased performance demands of IDPS and TLS inspection, Azure Firewall Premium utilizes a more powerful Virtual Machine SKU. Like Standard SKU, the Premium SKU can seamlessly scale up to 30 Gbps and integrates with availability zones to support the service level agreement (SLA) of 99.99 percent. The Premium SKU complies with Payment Card Industry Data Security Standard (PCI DSS) environment needs.

To simplify migration for Standard SKU customers, we used a common configuration approach using Azure Firewall Policy. This approach allows reusing existing API integration with minimal changes and continues managing Azure Firewall using Firewall Manager. Customers using firewall rules (Classic) will take an additional step for the migration to Azure Firewall Policy first. Azure Firewall Policy offers several advantages such as sharing common configuration across multiple firewalls, grouping rules using rule collection groups, and managing rules over time using policy analytics (Private Preview).

The Azure Firewall Premium SKU is optimally priced to provide the best value for state-of-the-art cloud-native firewall service. Premium SKU, with its advanced threat protection capabilities, offers compelling reasons to migrate on-premise high-security perimeter networks to the cloud. This approach helps avoid latency incurred back-hauling internet traffic to on-premises perimeter networks.

How cloud computing can improve 5G wireless networks

A great deal has been written about the technologies fueling 5G, especially how those technologies will improve the experience that users have regarding connectivity. Similarly, much has been said about how ongoing developments in technology will usher in a new generation of network-aware applications. In this article, we discuss one key aspect of 5G technology and how it will impact the development of wireless network capacity.

Rad More: DP-900: Microsoft Azure Data Fundamentals

This is one of the more important but often neglected aspects of wireless communication evolution. It represents yet another important reason why the convergence of cloud computing and wireless communications makes so much sense. To state it briefly, many of the complex problems associated with 5G wireless networks can be solved using software, which sets aside the need for costly, time-intensive, and often slow-to-evolve hardware that’s been used in the past.

Cloud and telecommunication: A perfect fit for next-generation networks

It is well understood that some of the most sophisticated technologies that make up 5G can be implemented in software running on off-the-shelf servers. This is exciting because we can slowly but surely walk away from specialized hardware, which has been used in all the previous four generations of telecommunication networks. Transitioning to software will help reduce the overall capital and operational expenses for telecommunication providers. Equally important, this shift from hardware to software will make such networks future-proof because they will empower the telecommunications industry to become nimble and aggressive when rolling out desirable features at a regular cadence rather than having to wait a decade or so for the next generation standards to emerge. Innovation will thrive as we create a world where going from one generation to another is a software upgrade, just as the cloud industry has been doing for over a decade.

We will say more about this in future blogs, but today, we want to discuss wireless capacity—or technically, spectrum efficiency. Hopefully, we will convince you that computing power can be used to increase cellular network capacity, and advances in software-based machine learning and data analytics techniques can be used to improve the efficiency of 5G and future networks. When adding this to the other elements of the ecosystem the marriage between cloud computing and telecommunications networks makes a perfect fit.

5G core technologies: Massive multi-user MIMO

Multiple-input and multiple-output (MIMO) is a method for multiplying the capacity of a radio link, using multiple transmission, and receiving antennas to exploit multipath propagation. MIMO is an essential element of wireless communication standards in Wi-Fi, 3G, and 4G. 5G, however, takes it to the next level with massive multi-user (MU) MIMO, scaling the number of antennas massively and supporting many users simultaneously. This technology is the key to 5G’s promise of 1,000 times the capacity gain over 4G.

The science behind massive MU-MIMO lies in the complex mathematics involved with manipulating signals sent to and received from every antenna so that communication channels with each user can be preserved and can survive the environmental distortion. This has been the subject of many technical books and academic studies, but you can find a simplified version in the illustration below.

Cloud Computing, Azure Exam Prep, Azure Learning, Azure Certification, Azure Career, Azure Tutorial and Material, Azure Cloud Strategy

Massive MU-MIMO involves lots of matrix multiplications and transpositions, all of which require significant computation. It is a direct function of the number of users being serviced by the cell tower, and the number of antennas the cell tower has. Furthermore, this computation takes place every few milliseconds for thousands of subcarriers. The implication here is that significant processing power and energy are needed. As network operators increase the number of antennas, the computational requirement goes up considerably, along with other associated problems.

User patterns also affect the amount of computation needed. The precoding method described in the above figure works best if the users are stationary or moving slowly. Otherwise, the precoding matrix must be recomputed frequently, needing even more computations. An alternative method, known as “conjugate beamforming,” may work better in this case, but the number of antennas must far exceed the number of users and the wireless capacity is generally reduced.

So, the overall capacity that the network delivers is a direct function of how much computation power the operator is willing to purchase and deploy at each of its thousands of cell towers. Edge computing, which allows the ability to scale up computing easily, is perfect for this. Even if some operators don’t need lots of capacity immediately, it is still vital to understand if the network is to be built in such a way that it can be easily scaled up as the demand for network capacity grows.

Microsoft has invested heavily in computation technology that can deliver massive MU-MIMO for 5G networks. As early as 2012, Microsoft Research invested in a practical solution to implement MU-MIMO, using distributed pipelines with a rack of commodity servers (an edge data center) to meet timing specs and to scale to hundreds of antennas (the technique was state-of-the-art and a report was published at SIGCOMM 2013).

Deep learning for wireless capacity


5G is moving towards an open architecture, with many ways to optimize a network. While this approach increases complexity, deep learning techniques can be used to take on these complexities, which are typically beyond human abilities to solve. In the above case about precoding for massive MIMO, we can apply deep learning techniques to select an algorithm that would reduce energy consumption while minimizing reduction in capacity. Through predictive analytics and modern software that adapts to dynamic network loads, 5G networks can become smarter.

Microsoft has invested heavily in machine learning and AI and supported the work of world-leading experts in this area. And we are working on augmenting telecommunication networks by designing deep learning algorithms that include domain knowledge. In addition to the example above, we are actively investigating how deep learning techniques may be used to control transmission power to reduce interference, and thus increase capacity.

Continuous machine learning (powered by flexible edge computing to model the dynamic radio frequency environment and user mobility patterns), along with managing the signal processing pipeline, creates a tremendous value proposition for the telecommunications industry. This massive step forward empowers the rapid incorporation of research breakthroughs into the system—not only for the purpose of increasing wireless capacity, but also to improve the total operational efficiency of 5G networks.

Azure: Where edge computing, the cloud, and telecommunication operators come together


For more than 10 years, Microsoft has invested heavily in edge computing and is continuing to do so. In particular, Azure is working to provide computation close to the cell towers where it will benefit network operators the most, as they look to cost-effectively scale their network. Additionally, through its Azure for Operators initiative, Microsoft is continually working to enable new first and third-party solutions that further enhance and simplify edge computing, from network connectivity to on-demand compute, to complete orchestration.

Given Microsoft’s ability to scale computation up as much and as often as operators demand, the power of technology at the edge—including massive MU-MIMO—is the answer that telecommunication operators have been looking for. Azure is here to support telecommunication operators in meeting their goals for increasing capacity as the network grows and evolves. While telecommunication providers increase the number of antennas and cell towers, Microsoft’s ability to spin up servers at scale and to manage them from anywhere in the world makes Azure the perfect fit for 5G and beyond for telecommunication networks.

Manage RDP and SSH connectivity at scale with Azure Bastion

Securely manage remote connectivity at scale

Security is at the forefront of user and administrator connectivity to cloud services. As enterprises continue to move mission-critical applications to the cloud, the need for secure, scalable, and reliable remote public connectivity and jumpbox services increases. With this shift, enterprises are moving away from exposing public IP addresses on virtual machines (VMs) and cloud infrastructure running their applications, and instead, are relying on managed jumpbox services to facilitate user connectivity. Fundamentally, remote connectivity and managed jumpbox services need to provide four core capabilities:

1. Secure public access that minimizes the exposure of public IP addresses and entry points to the target applications.

2. Single deployments that manage connectivity across local or connected Virtual (private) Networks.

3. Infrastructure scaling capabilities that manage the number of concurrent remote connections.

4. Metrics, monitoring, and alerting on the infrastructure facilitating remote connectivity.

Secure public access

Traditional (on-premises) jumpbox solutions are often deployed to a semi-trusted management network. This network is separate from the local network containing application services and private endpoints. The public IP address of the jumpbox solution is defined in the management network and connectivity to applications and private endpoints in the target local network are enabled via a virtual private network (VPN) solution. Users then connect to the private IP address of the jumpbox solution in the management network and establish remote connectivity to the destination application via the VPN connection. Alternatively, some enterprises deploy applications to the management network and expose public IP addresses on the VMs hosting the target applications, and users establish Remote Desktop Protocol (RDP) and Secure Shell (SSH) connections directly to the application. However, this approach broadens the potential attack surface by scaling out public IP addresses to any VM requiring remote user connectivity. Ultimately, the need for trusted and secure access is critical for enterprise workloads.

Azure Bastion is a fully managed jumpbox-as-a-service that provides secure RDP and SSH connectivity to VMs deployed in any local or peered Azure Virtual Networks. Remote connectivity is established directly from the Azure Portal, over a transport layer security (TLS) connection, to the public IP address of Azure Bastion. From there, Azure Bastion establishes RDP and SSH sessions to the private IP address of the target VMs in the local or peered Virtual Network. As customers deploy additional VMs to their Virtual Networks, Azure Bastion facilitates remote connectivity to both the existing and newly configured VMs, using a single public IP address. Additionally, customers can configure Network Security Groups (NSGs) to restrict inbound public access to the public IP address of Azure Bastion, creating a more secure access perimeter.

Single deployment that manages connectivity across local or connected Virtual Networks


Modern enterprises often leverage a hub-and-spoke topology when building application services. This type of architecture centralizes management Network Virtual Appliances (NVAs) and jumpbox services in a hub network and applications are deployed to connected spoke networks. Application traffic then traverses the hub network before reaching the target spoke application.

With Azure Bastion and Virtual Network peering, customers can continue to facilitate remote connectivity from a hub-and-spoke architecture within Azure. Specifically, customers can deploy Azure Bastion to a hub Virtual Network and configure application VMs in the spoke networks. Once the customer configures Virtual Network peering between the hub and spoke networks, Azure Bastion can manage RDP and SSH connectivity to VMs within the local hub Virtual Network and across the peer to VMs in the application spoke Virtual Networks.

Infrastructure scaling capabilities


One of the primary reasons enterprises are shifting mission-critical workloads to the cloud is to take advantage of platform-as-a-service (PaaS) infrastructure scaling capabilities. Specifically, with the click of a button, customers can scale-up and scale-out infrastructure to meet any increase in demand or traffic to their applications. Furthermore, as customers deploy additional applications to spoke networks, the volume of traffic traversing the hub network increases. As a result, the infrastructure facilitating NVAs and jumpbox services deployed to the hub network needs to be able to scale to serve the additional workload(s).

Azure Bastion now supports manual host scaling. When customers deploy a Standard Azure Bastion, they can configure between 2 and 50 scale units. Additionally, customers can manage the number of instances in the Azure Bastion configuration blade after the resource is created. RDP and SSH are usage-based protocols. Depending on the number of concurrent sessions and the workloads of each session, customers may need to scale out additional instances to serve application connectivity. Specifically, as customers either deploy additional applications to the spoke network(s) and or peer additional spoke networks to the hub network, they may need to scale out host instances to maintain Azure Bastion connectivity. Ultimately, support of both Virtual Network peering and host scaling enables Azure Bastion to manage remote connectivity globally.

Metrics monitoring and alerting


Another key benefit of cloud services is near-to-real-time metrics, monitoring, and alerting on the performance, availability, and traffic of infrastructure-as-a-service (IaaS) and PaaS resources. Enterprises often monitor and enable custom alerting on metrics within these three categories to proactively detect any performance issues—and more importantly, to scale-out infrastructure services as application demand increases, prior to any potential outages.

With Azure Bastion and Azure Monitor, customers can enable alerting across availability, performance, and traffic metrics. With these capabilities, customers can monitor central processing unit (CPU) utilization, memory utilization, session count, and split by host instance to gauge when to scale out host instances.

Deploy, manage, and monitor infrastructure with the click of a button


With these changes to Azure Bastion, customers can now reliably manage secure remote connectivity to applications at scale. As enterprises continue to shift production workloads to the cloud, it is imperative that cloud providers invest in PaaS offerings that expose the underlying platform benefits to customers. Ultimately, enterprises should be able to deploy, manage, and monitor infrastructure with the click of a button—reallocating the effort previously spent on infrastructure management to application development.
