Retaining Optimize CPUs configuration during Amazon EC2 scaling to save on licensing costs
Compute Blog
The article discusses a new feature on Amazon EC2 that allows you to modify CPU configurations after an instance has launched. This helps optimize CPU licensing costs for workloads like SQL Server by allowing you to disable simultaneous multithreading (SMT) or reduce the number of CPU cores.
Specifically, the article covers:
- Why CPU configuration matters for different workloads like compute-intensive, database, and HPC workloads.
- Three ways to set or modify CPU configurations: through the EC2 Dashboard, during instance size/type change, or using the CLI/API.
- How to track license usage with optimized CPUs in AWS License Manager.
- The benefits of this feature, including flexibility, performance optimization, licensing cost savings, and streamlined operations.
