Hello, and welcome to this quick lecture, where I will introduce you to Amazon MemoryDB for Redis. This service is newly in scope for both the AWS Certified Developer - Associate and AWS Certified DevOps Engineer - Professional exams, so I wanted to give you a quick overview of this service and what it does.

Amazon MemoryDB for Redis is a fully managed in-memory data store service that’s compatible with the popular open-source Redis data structure store. It’s designed to provide ultra-fast, low-latency access to data stored in memory, providing microsecond read and single-digit millisecond write latencies.

MemoryDB for Redis gets deployed as a cluster within your VPC. And each cluster consists of one or more nodes that are responsible for serving a single dataset. That dataset is partitioned into shards, and each shard will have a primary node and, optionally, up to 5 read replica nodes. You can even spread these replica nodes across availability zones to provide high availability. And of course, there are built-in failover capabilities, which allows a replica node to be promoted to the primary node for a given shard in the event of a failure in the current primary node.

MemoryDB for Redis also supports a number of other advanced features, such as:

  • Clusters up to 500 nodes in size, which depending on node configuration can offer up to 100 TB of data storage,

  • Transaction logs that are distributed across multiple availability zones to ensure your data is durable, consistent, and quickly recoverable in the event of a failure,

  • Data tiering, which allows you to move data that is accessed less frequently to disk,

  • Support for encryption of data both in transit and at rest, and

  • Snapshots for easy backup and restore of your MemoryDB cluster.

So to recap, Amazon MemoryDB for Redis offers ultra-fast access to in-memory data sets and can help you reduce the complexity and cost of managing data store infrastructure for your applications.

I hope you’ve enjoyed this quick introduction to MemoryDB for Redis. Thanks for joining me, and best of luck on your certification journey!
