DCsv2-series VM now generally available from Azure confidential computing

Security and privacy are critically important when storing and processing sensitive information in the cloud, from payment transactions, to financial records, personal health data, and more. With the general availability of DCsv2-series VMs, we are ushering in the start of a new level of data protection in Azure.

With more workloads moving to the cloud and more customers putting their trust in Microsoft, the Azure confidential computing team continues to innovate to provide offerings that keep and build upon that trust. Starting with our world-class security researchers, and working closely with industry partners, we are developing new ways to protect data while it’s in use with Azure confidential computing. DCsv2-series VMs can protect the confidentiality and integrity of your data even while it’s processed.

What is confidential computing?

There are ways to encrypt your data at rest and while in transit, but confidential computing protects the confidentiality and integrity of your data while it is in use. Azure is the first public cloud to offer virtualization infrastructure for confidential computing that uses hardware-based trusted execution environments (TEEs). Even cloud administrators and datacenter operators with physical access to the servers cannot access TEE-protected data.

By combining the scalability of the cloud and ability to encrypt data while in use, new scenarios are possible now in Azure, like confidential multi-party computation where different organizations combine their datasets for compute-intensive analysis without being able to access each other’s data. Examples include banks combining transaction data to detect fraud and money laundering, and hospitals combining patient records for analysis to improve disease diagnosis and prescription allocation.

Data protection powered by Intel hardware

Our DCsv2 confidential computing virtual machines run on servers that implement Intel Software Guard Extensions (Intel SGX). Because Intel SGX hardware protects your data and keeps it encrypted while the CPU is processing it, even the operating system and hypervisor cannot access it, nor can anyone with physical access to the server.

Microsoft and Intel are committed to providing best-in-class cloud data protection through our deep ongoing partnership:

“Customers are demanding the capability to reduce the attack surface and help protect sensitive data in the cloud by encrypting data in use. Our collaboration with Microsoft brings enterprise-ready confidential computing solutions to market and enables customers to take greater advantage of the benefits of cloud and multi-party compute paradigms using Intel® SGX technology.” —Anil Rao, VP Data Center Security and Systems Architecture, Intel

Partners in the Azure Marketplace

Microsoft works directly with platform partners to provide seamless solutions, development, and deployment experiences running on top of our Azure confidential computing infrastructure. Software offerings can be discovered through our Azure Marketplace including:

◉ Fortanix— Offers a cloud-native data security solution including key management, HSM, tokenization, and secrets management built on Azure confidential computing.

◉ Anjuna— Delivers secure Azure instances using end-to-end CPU hardware-level encryption without changing your application or operations.

◉ Anqlave— A valued partner in Singapore, offers enterprise ready confidential computing solutions.

“Anqlave’s proprietary, institutional-grade modern key management and data encryption solution addresses the most critical security issues we face today. With Anqlave Data Vault (ADV) secret management allows users to securely create, store, transport and use its secrets. Leveraging Azure confidential computing, allows us to make this technology more accessible to our enterprise customers and easily support their scale. Providing a secure enclave that is portable in the cloud is one the key reasons why our enterprises will prefer to host their ADV on Azure confidential computing regardless of their other cloud infrastructure.” —Assaf Cohen, CEO, Anqlave

How customers are succeeding with Azure confidential computing

Customers are already using Azure confidential computing for production workloads. One customer is Signal:

“Signal develops open source technology for end-to-end encrypted communications, like messaging and calling. To meet the security and privacy expectations of millions of people every day, we utilize Azure confidential computing to provide scalable, secure environments for our services. Signal puts users first, and Azure helps us stay at the forefront of data protection with confidential computing.” —Jim O'Leary, VP of Engineering, Signal

While many applications and services can take advantage of data protection with confidential computing, we have seen particular benefits with regulated industries, such as financial, government, and healthcare. Companies can now take advantage of the cloud for processing sensitive customer data with reduced risk and higher confidence that their data can be protected, including when processing.

For example, MobileCoin, a new international cryptocurrency trusts Azure confidential computing to support digital currency transfers. Their network code is now available in open source, and a TestNet is available to tryout:

“MobileCoin partners with Azure because Microsoft has decided to invest in trustworthy systems. Confidential computing rides the edge between what we can imagine and what we can protect. The praxis we've experienced with Azure allows us to commit to systems that are integral, high trust, and performant.” —Joshua Goldbard, CEO, MobileCoin

Confidential computing has proven useful for enterprise-grade blockchain, enabling fast and secure transaction verification across a decentralized network. Fireblocks is yet another customer taking advantage of Azure confidential computing infrastructure:

“At Fireblocks, our mission is to secure blockchain-based assets and transactions for the financial industry. Once we realized the traditional tech stack was not suitable for this challenge, we turned to Azure confidential computing and Intel SGX to implement our patent-pending technology. Our customers trust Fireblocks to securely store and move their digital assets—over $6.5 billion of them each month—and Azure provides a backbone for us to deliver on that promise.” —Michael Shaulov, CEO and co-founder, Fireblocks

Industry leadership bringing confidential computing to the forefront

Microsoft is not alone in bringing confidential computing to the forefront of the cloud computing industry. In September 2019, we were a founding member of the Confidential Computing Consortium (CCC), which now consists of dozens of companies working to develop and open source technologies and best practices for protecting data while it’s in use. These companies include hardware, cloud, platform, and software providers.

Microsoft is also committed to the developer experience to ensure platform partners and application developers can build solutions that take advantage of confidential computing. We donated our Open Enclave SDK to the consortium, an open source SDK for developing platforms and applications on top of confidential computing infrastructure.
