Trace3 Cloud FinOps: Save Money in an Instance!
& Amanda Wagner | Associate Cloud FinOps Consultant, Trace3 Cloud Solutions
In one of our recently published blogs we shared our teams’ experiences at AWS Re:Invent and included our thoughts on Graviton. As discussed, moving an instance to Graviton has cost advantages but can often reveal compatibility issues with existing code. Graviton is not the only alternative to Intel. In 2018, Advanced Micro Devices threw their hat in the ring by launching their first AMD EPYC line of processors on AWS. Their instances offer competitive pricing while maintaining or boosting performance and usually requires no architecture changes.
Last month, we had the opportunity to meet with the AMD team to learn about their compute offerings and how they have expanded their footprint. We reviewed performance, security, and compatibilities. We know you’re wondering, “what’s Trace3’s take on all of this?”
Changing instance types within your environment may be daunting to some, but AMD makes it accessible with 14 unique EC2 instance types in 23 out of 30 AWS regions as well as 70 availability zones. A huge plus to AMD is that it runs on the AMD64 (x86_64) architecture. Unlike moving to a Graviton instance running on ARM architecture, you won’t be faced with potentially redesigning your workload to migrate from Intel EC2 to AMD EC2 instances. In addition, AMD instances are 10% less expensive than comparable instances in most cases, and up to 45% less expensive in India regions. All without impacting performance.

In January of 2023, AMD achieved High Performance Computing (HPC) competency status through the AWS competency program, a standard that continues to evolve as various capabilities advance. AMD demonstrated technical proficiency and proven customer success in HPC solutions to achieve this competency.

AMD has prioritized being a leader in the security space too. All AMD EPYC processors feature a suite of security features called AMD Infinity Guard. Infinity Guard encrypts the main memory, as well as the virtual machine, helping to prevent certain cold-boot attacks and provides a layer of protection for data confidentiality. AMD reports that this full memory encryption is achieved with high-performance encryption engines integrated into the memory channels, without compromising on performance.

As for VM encryption, this chip is currently the only x86 processor with built-in Secure Encrypted Virtualization – Secure Nested Paging (SEV – SNP), which encrypts each VM with one of up to 509 unique encryption keys. It is important to note that no changes or refactoring is required to take advantage of SEV-SNP on AMD. So, for the most security conscious customer looking to protect data-in-use, AMD EPYC-powered instances are an excellent choice.
Due to the lack of awareness of AMD instance availability, this option is often overlooked. Search for instance types with the “a” (E.g.- M6a) to see if a more cost-effective and secure option with the same or better performance is available for your workload.
