AWS’s ElastiCache Redis Clusters Just Got 10% More Memory—Like Magic!

Late last year, AWS launched support for Valkey—a fully open-source, drop-in replacement for Redis—bringing significant cost savings to ElastiCache users.
For those who missed the announcement, here are the key takeaways:

• 33% lower cost for serverless Valkey compared to Redis OSS serverless.
• 20% savings on node-based Valkey vs. Redis node-based.
• Reserved Instance (RI) flexibility and prorated RI transfer to Valkey.
• Zero-downtime migration from Redis OSS.

Now, with Valkey 8, AWS users have even more reasons to consider migrating.

What’s New in Valkey 8?
The latest version introduces several performance, security, and efficiency improvements:

• 10% memory savings from key storage optimizations, reducing resource usage without impacting performance
• Over 4x the ElastiCache Serverless scaling speed, handling 5 million requests per second in just 13 minutes
• Stronger security with fixes for ACL issues and Lua vulnerabilities
• Better observability with per-slot and per-client insights, including event loop latency, rehash memory tracking, and traffic breakdowns

With ElastiCache now supporting Valkey 8 (version 8.0.1), there’s no reason to wait.
