What Are 2 Types of Amazon ElastiCache?

Amazon ElastiCache is a web service that simplifies the process of deploying, managing, and scaling distributed in-memory cache environments in the cloud. It provides high performance and eliminates the complexity associated with deploying and managing distributed cache environments. Amazon ElastiCache is an ideal choice for applications that require sub-millisecond response times and a high throughput for read and write operations.

Amazon ElastiCache provides two types of caching services: Redis and Memcached. Both are open source caching solutions, but they have different underlying data models.

Redis

Redis is an open source, in-memory data structure store designed to be used as a database, message broker, or caching system. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperlogs, geospatial indexes with radius queries and streams. Redis also offers features such as master/slave replication for high availability, auto-failover for disaster recovery purposes.

Memcached

Memcached is an open source distributed memory caching system designed to speed up dynamic web applications by reducing database load times by storing data in memory instead of on disk or other slower storage systems. It supports basic data structures such as strings and integers as well as complex objects like lists and hashes. Memcached also offers features such as replication for fault tolerance and better performance.

Conclusion:

Amazon ElastiCache provides two types of caching services: Redis and Memcached. Redis is an open source in-memory data structure store while Memcached is an open source distributed memory caching system. Both offer features such as master/slave replication for high availability and auto-failover for disaster recovery purposes.
