AWS Certified Solutions Architect Associate (SAA-C03) - ElastiCache

Elastic Cash is an AWS service that provides in-memory caching for databases, enhancing performance by storing data in memory rather than on disk. It offers two solutions: Memcached, which is simple and high-performing, and Redis, which is compliant with regulations like HIPAA. The AWS Elasticache interface allows users to set up and manage caching clusters. Choosing the right node type is crucial for ensuring sufficient memory for caching needs.
