What are the main caching tools used in AWS infrastructure?

In AWS, the most commonly used tools for caching are:

• Amazon ElastiCache — a managed in-memory caching service that supports Redis and Memcached. It helps accelerate data access and reduce database load.
• Amazon CloudFront — a CDN service that caches static and dynamic content at edge locations, improving content delivery speed to users.
• DynamoDB Accelerator (DAX) — a cache at the DynamoDB database level that reduces read latency.

These tools help improve application performance by decreasing access time to frequently used data.
