Storage¶
The choice of storage system depends on the deployment needs. The Relock service supports any Redis OSS-compatible solution, including Valkey, Memcached, KeyDB, and managed cloud services like Amazon ElastiCache. Each option offers different trade-offs in terms of performance, scalability, features, and operational complexity:
Valkey: A fully open-source fork of Redis, created to maintain an open governance model after Redis adopted a source-available license. Valkey is compatible with Redis clients and is a solid choice for those who want to remain in the open-source ecosystem without vendor lock-in.
Memcached: A lightweight, high-performance memory caching system. It supports simple key-value pairs and is well-suited for use cases where persistence, replication, or complex data structures aren’t needed.
KeyDB: A Redis-compatible database offering advanced features such as multi-threading, active-active replication, and built-in TLS support. It’s a good option for applications requiring high throughput and enhanced performance without changing the Redis API.
Amazon ElastiCache (for Redis or Memcached): A fully managed, scalable, and highly available in-memory data store service from AWS. ElastiCache removes the operational overhead of managing infrastructure, provides built-in monitoring and security, and is ideal for production environments needing reliability and ease of maintenance.
Other cloud-based Redis-compatible services: Providers like Azure Cache for Redis, Google Memorystore, and Upstash offer similar managed Redis solutions with varying levels of scalability, regional availability, and pricing models.
When choosing a solution, consider factors such as required performance, operational overhead, cost, licensing preferences, and whether there’s a preference to manage infrastructure directly or use a cloud-managed service.
