In tech, caching is ubiquitous. CPUs use L1, L2, and L3 caches, and mobile phones cache app data locally. Streaming services cache content on the edge, browsers cache images, and more. The same is true for databases. Imagine if, on a gaming site, every time a leaderboard was displayed, a query had to do a […]

In this post, I will describe how you can leverage ElastiCache for Redis with cluster mode enabled to enhance reliability and availability with little change to your existing workload. Cluster Mode comes with the primary benefit of horizontal scaling up and down of your Redis cluster, with almost zero impact on the performance of the cluster, as I will demonstrate later. If you have ever encountered a Redis cluster that is over or under-provisioned or just want to better understand its inner workings, please read on.

In Amazon ElastiCache for Redis, your applications use the provided endpoints to connect to an ElastiCache node or cluster. According to Amazon ElastiCache for Redis Components and Features in the ElastiCache for Redis User Guide, a multiple-node Redis (cluster mode disabled) cluster has two kinds of endpoints: “The primary endpoint always connects to the primary […]

Most often, when we discuss Amazon ElastiCache, it is in the context of enhancing the performance of read-heavy database workloads. We update our applications to employ a read-through or write-through pattern to keep data in the cache fresh and ease the burden on the database. When used in this context, ElastiCache accelerates your high volume […]

A challenge that some organizations face when moving to the cloud is how best to migrate or integrate old legacy infrastructure with restrictive licensing to an environment that offers a breadth of functionality and pay-as-you-go pricing. AWS provides many options to help customers in their analysis and planning. One common approach is to establish a […]
