PERF 14. How do you ensure you continue to have the most appropriate proximity and caching solutions as new solutions are launched?
AWS listens to customer feedback and continues to innovate with new proximity and caching solutions, providing new combinations of proximity, caching, and latency. This means that new proximity and caching solutions might be released that offer better performance efficiency than the one you originally selected. Look for opportunities to reduce latency and increase performance throughout the system. For example, did you complete a one-time optimization or are you continuing to optimize your system as demand changes over time?Best practices: Review Cyclically reselect a new instance type and size based on predicted resource needs. Benchmarking After each new instance type is released, carry out a load test of a known workload on AWS, and use that to estimate the best selection. Load Test After each relevant new instance type is released deploy the latest version of the system on AWS, use monitoring to capture performance metrics, and then select based on a calculation of performance/cost. Proactive Monitoring–Amazon Cloud Watch monitoring Use Amazon CloudWatch to monitor proximity and caching solutions. Proactive Monitoring–Third-party monitoring Use third-party tools to monitor proximity and caching solutions. Alarm-based notification Plan for your monitoring systems to automatically alert you if metrics are out of safe bounds. Trigger-based actions Plan for alarms to cause automated actions to remediate or escalate issues.
