How to configure and scale Redis in a high-availability setup?

[liya_09]

We use Redis as a cache layer for a Django app on AWS EC2. We’ve experienced occasional downtime and data loss. What’s the best way to configure Redis for HA and persistence?

To configure Redis for high availability on AWS EC2, use Redis Sentinel for automatic failover with a master-replica setup and enable AOF persistence to prevent data loss. For better scalability, use Redis Cluster to shard data across multiple nodes. Alternatively, consider Amazon ElastiCache for Redis, which offers a fully managed, scalable, and fault-tolerant solution.
