Trade-offs - Performance Efficiency Pillar


When you architect solutions, think about trade-offs to ensure an optimal approach. Depending on your situation, you could trade consistency, durability, and space for time or latency, to deliver higher performance.

Using AWS, you can go global in minutes and deploy resources in multiple locations across the globe to be closer to your end users. You can also dynamically add read-only replicas to information stores (such as database systems) to reduce the load on the primary database.

AWS offers caching solutions such as Amazon ElastiCache, which provides an in-memory data store or cache, and Amazon CloudFront, which caches copies of your static content closer to end users. Amazon DynamoDB Accelerator (DAX) provides a read-through/write-through distributed caching tier in front of Amazon DynamoDB, supporting the same API, but providing sub-millisecond latency for entities that are in the cache.
