ValKey vs Redis: AWS's Game-Changing Move and What It Means for E-commerce

The database world is buzzing with AWS's recent announcement: significant price cuts for ValKey services, coupled with full support in ElastiCache and MemoryDB. This move marks a seismic shift in the cloud database landscape, one that e-commerce businesses should pay close attention to.

The Redis Licensing Shakeup

At the heart of this development lies Redis's controversial decision to change its licensing model. By moving from an open-source license to the more restrictive Business Source License (BSL), Redis has effectively put itself at odds with major cloud providers. This change makes Redis less attractive and potentially more expensive for companies like AWS to offer as a managed service.

AWS Responds with ValKey

AWS's response has been swift and calculated. By throwing its considerable weight behind ValKey, a Redis fork, AWS is sending a clear message: they're not willing to be held hostage by restrictive licensing terms. Here's what AWS has done:

1. Added full support for ValKey in ElastiCache and MemoryDB
2. Slashed prices for ValKey services:
   • 33% reduction for ElastiCache Serverless
   • 20% cut for node-based ElastiCache
   • 30% decrease for MemoryDB

In our opinion, this is a masterstroke by AWS. They're simultaneously addressing the licensing issue, potentially reducing their own costs, and offering customers a compelling reason to switch to ValKey.

What This Means for E-commerce Businesses

For online retailers, especially those running on AWS, this development is significant. Here's why:

1. Cost Savings: The price reductions alone make ValKey an attractive option. For high-traffic e-commerce sites, this could translate to substantial savings.

2. Performance Potential: Early benchmarks suggest ValKey performs on par with, if not better than, Redis in many scenarios.

3. Future-Proofing: AWS's backing of ValKey indicates long-term support and continued optimization.

4. Low-Risk Transition: ValKey's strong backwards compatibility with Redis minimizes migration risks.

The Badger Commerce Experience

At Kedos, we recently guided our e-commerce SaaS subsidiary, Badger Commerce, through a migration from Redis to ValKey. While Badger Commerce doesn't use AWS, our experience offers valuable insights for businesses considering a similar move.

Smooth Sailing: Backwards Compatibility

We were impressed by ValKey's compatibility with Redis:

• Existing Redis clients connected to ValKey without any code changes.
• All Redis commands we used were fully supported in ValKey.
• Our data structures transitioned seamlessly.

The Migration Process

Our step-by-step approach ensured a successful transition:

1. Thorough Assessment: We cataloged our Redis usage, confirming ValKey support for all our use cases.
2. Parallel Testing: We set up a ValKey instance alongside Redis, using replication for real-time data synchronization.
3. Gradual Rollout: We migrated non-critical services first, using feature flags for easy rollback if needed.
4. Performance Validation: Rigorous benchmarking confirmed performance improvements.
5. Full Cutover: The final switch was completed during a planned maintenance window.

Tangible Benefits

Post-migration, Badger Commerce saw:

• 20% improvement in response times for key operations.
• Enhanced memory efficiency, boosting scalability during traffic spikes.
• Flawless execution of existing Lua scripts and Pub/Sub functionality.

Our Take: A Strategic Move for E-commerce

In our professional opinion, the shift from Redis to ValKey represents more than just a technical upgrade—it's a strategic move that can yield significant benefits, especially for AWS users. The combination of cost savings, performance improvements, and AWS's clear commitment to ValKey makes this transition worth serious consideration.

For e-commerce businesses, where every millisecond of latency and every dollar saved can impact the bottom line, the ValKey proposition is particularly compelling.

At Kedos, we're excited about the possibilities ValKey opens up. Whether you're running on AWS or another platform, we believe the ValKey transition is a move worth evaluating. Our team, with its deep expertise in both AWS technologies and e-commerce solutions, is ready to help businesses navigate this transition smoothly and capitalize on its benefits.

The database landscape is shifting, and with ValKey, AWS has dealt a strong hand. It's time for e-commerce businesses to consider their next move carefully.
