Highly Available Redis Clusters with Automated Sharding Launches at ScaleGrid

PALO ALTO, Calif., January 24, 2019 – ScaleGrid, a rising leader in the Database-as-a-Service (DBaaS) space, has just announced support for Redis Clusters on their fully managed Redis hosting plans. Redis Cluster is the native sharding implementation available within Redis, an open-source in-memory data structure project, that allows you to automatically shard across multiple Redis nodes without having to rely on external tools and utilities.

ScaleGrid is no novice when it comes to deploying and managing complex, sharded clusters in the cloud, as they have provided one of the most powerful sharding tools for their MongoDB hosting solutions since 2013.

Once you have a cluster up and …

Why you don’t want to shard.

Note: This blog post is part 1 of 4 on building our training workshop.

The Percona training workshop will not cover sharding. If you follow our blog, you'll notice we don't talk much about the subject; in some cases it makes sense, but in many we've seen that it causes architectures to be prematurely complicated.

So let me state it: You don't want to shard.

Optimize everything else first, and then if performance still isn't good enough, it's time to take a very bitter medicine. The reason you need to shard basically comes down to one of …
