Amazon ElastiCache for Valkey: Save Up to 33% on Your Redis Costs with Zero-Downtime Migration

ould you say no to $800,000 in savings with just a few clicks? That's not a hypothetical question – it's a real result one enterprise achieved by switching their ElastiCache deployment to Amazon ElastiCache for Valkey. In an era where cloud costs can spiral out of control, Amazon ElastiCache for Valkey isn't just another cost-cutting tool – it's a complete Redis-compatible solution that's reshaping how we think about cloud caching costs.

What is Valkey and Why It Matters

Valkey is like upgrading from a reliable sedan to a hybrid car - you get the same familiar driving experience but with better performance and lower running costs. As an open-source fork of Redis version 7.2.4, Valkey is fundamentally similar to Redis - both offer an in-memory data store and cache. It's fully compatible with Redis OSS 7.2 and all earlier open source Redis versions, which means existing Redis applications can switch to Amazon ElastiCache for Valkey without any code changes.

The Cost Advantage: Numbers That Will Make You Smile

Let's talk money, because this is where Amazon ElastiCache for Valkey really shines compared to Amazon ElastiCache for Redis OSS. AWS has made it incredibly simple to switch between these managed services, and the cost benefits are compelling:

• Serverless Savings: Up to 33% lower pricing compared to other ElastiCache engines
• Node-based Savings: 20% lower pricing for self-designed clusters
• More Granular Data Storage Billing: ElastiCache charges for both compute (ECU) and data storage. With Valkey, your data storage is rounded to the next 100MB, while Redis rounds to the next 1GB - making you pay closer to what you actually use

To put this in perspective, let's look at a real-world example of running an empty cache in eu-west-1:

With Amazon ElastiCache for Redis OSS:

720 hours * $0.14/hour * 1 GB = $100.8/month 
(minimum 1GB billing even for an empty cache)

With Amazon ElastiCache for Valkey:

720 hours * $0.094/hour * (100MB) = $6.77/month
(minimum 100MB billing for an empty cache)

This dramatic difference in starting costs makes Valkey particularly attractive for development environments or smaller applications. The combination of lower hourly rates and more granular storage increments (100MB vs 1GB) means you can start small and scale up as needed, paying closer to what you actually use.

Performance Benefits That Come as a Bonus

While cost savings are the headline act, Valkey brings some impressive performance improvements to the stage:

• Improved multi-core utilization
• Enhanced asynchronous I/O threading
• Up to double the throughput for the same core count
• 20.6% reduced memory usage

Think of it as getting a sports car for the price of a sedan – you're not just saving money, you're getting better performance too.

Migration Made Simple: No Drama, No Downtime

Here's where Amazon ElastiCache for Valkey really shines – the migration process. The migration from Amazon ElastiCache for Redis to Amazon ElastiCache for Valkey is:

• Zero downtime
• No code changes required
• In-place replacement
• Available in all AWS regions

It's literally a few clicks in your AWS console. That's it.
