What is a node in ElastiCache?
A node is the smallest building block of an Amazon ElastiCache deployment. It is a fixed-size chunk of secure, network-attached RAM. Each node runs the engine that was chosen when the cluster or replication group was created or last modified. Each node has its own Domain Name Service (DNS) name and port.
Is ElastiCache like Redis?
Redis: What Are The Differences? A big difference between ElastiCache and Redis is that Amazon Elasticache is a managed platform, whereas Redis is an open-source caching service and data store.
Can I use ElastiCache as a database?
You can use ElastiCache for caching, which accelerates application and database performance, or as a primary data store for use cases that don't require durability like session stores, gaming leaderboards, streaming, and analytics.
