As part of the announcement of the new EPYC 7003 (Milan) processors, AMD and Microsoft have announced new solutions based on these CPUs in the Azure cloud. The first, which is in private beta testing, is designed for so-called secure or confidential computing (Confidential Computing). Microsoft Azure has been innovating in this area for years.
For more than three years, financial and government services, health care providers, and even messengers have been using this security technology for distributed machine learning, for example, or to move their sensitive data to the cloud. Azure CTO Mark Russinovich announced Monday that the service further expands Azure's privacy computing capabilities. Azure will be the first major cloud provider to offer confidential virtual machines on AMD's new 7003-series EPYC processors.
They will complement existing Azure solutions, such as privacy containers for Azure Kubernetes service, and open up the possibility of creating new secure applications without the need for code modification, which in turn will make it much easier to create them. This is based on AMD's new Secure Encrypted Virtualization (SEV) & ; Secure Nested Paging, or SEV-SNP. SEV-SNP secures virtual machine memory from the hypervisor itself.
Encryption keys are generated by a separate coprocessor directly inside the EPYC. This ensures that no one, including cloud administrators, workloads, applications or data on virtual machines, has access to them. Azure's second innovation & ; virtual machines with AMD EPYC 7003-series Azure HBv3 processors, optimized for high-performance computing (HPC), are available in a number of Azure regions in the US and Western Europe.
They will also soon be available in the rest of the U.S. and Southeast Asia. HBv3s have up to 120 cores of AMD EPYC 7003 Series CPUs, 448 GB of RAM and do not support multi-threading (SMT). The HBv3 series virtual machines also provide up to 340 GB/s memory bandwidth, up to 32 MB of L3 cache per core, block SSD storage at up to 7 GB/s and clock speeds up to 3.675 GHz. All HBv3 series virtual machines have dedicated NVIDIA Mellanox HDR InfiniBand 200Gbps connectivity for MPI operation.
