Customers are always looking to optimize performance and cost for their workloads. With new Amazon Elastic Compute Cloud (Amazon EC2) instances featuring AMD EPYC processors, you can do just that. In this session, we showcase how Amazon EC2 M5a, R5a, and T3a instances can save you 10% on infrastructure cost for right-sized workloads. We discuss the benefits, use cases, and customer successes of these new instances.

Customer Scenarios
Customer A
Application: Customer service front end
Use Case: ECS (Elastic Container Service)
to run their microservices that were I/O
bound, typically waiting for transactions
to a database.
Result: They were able to easily migrate
from M4’s and M5’s to M5a, due to the
application compatibility, and save >10%
in their infrastructure costs with no
noticeable impact to performance
Customer B
Application: Java application servers
Use Case: Running a business application
that uses Java, which is memory bound
and leaves the CPU idle.
Result: The customer was able to easily
migrate from R4 to R5a, save >10% in
their infrastructure costs with no impact
to their application performance and only
a slightly higher CPU utilization.

Customer Scenarios
Customer C
Application: Amazon ElastiCache
Database
Use Case: Over 1TB of data storing
simulation results. Needs quick access for
feedback into simulation modeling.
Result: Cost and memory capacity is key,
and the R5a instances fit perfectly as they
offer 10% lower $ / GiB of memory.
Migration to R5a was easy and there was
no noticeable impact to performance.
Customer D
Application: SAP NetWeaver
Use Case: An SAP enterprise application
server that is very CPU intensive with
large licensing costs
Result: For this workload, the customer
was interested in the new AMD instances
to save money. However, when they ran
their benchmark and determined that
they were only able to achieve ~70% of
the performance at 10% lower cost; it was
not a good fit in this case.
