ElastiCache is protocol-compliant with open source Redis though, so no code changes should be required to move from open source to ElastiCache as long as you are on a supported versions. Currently, those are Redis 5.0.0, 4.0.10, 3.2.10, 3.2.6, 3.2.4, 2.8.24, 2.8.23, 2.8.22, 2.8.21, 2.8.19, 2.8.6, and 2.6.13.

Only advantage using Elasticache probably its managed solution in AWS but moreless it works as Redis OSS. (actually provision separate EC2 for each Redis deployment). Elasticache always behind latest Redis OSS version (normally n-1) so you always miss latest features compare to Redis OSS.

Redislabs, a company behind Redis OSS has better re-architected managed Redis Enterprise service available on AWS, GCP, Azure as well as as Software solution. It has

  1. Better linear scale
  2. Better performance, HA, Persistence options
  3. Modules support like RediSearch, RedisGraph, RedisAI, RedisJSON, RedisTimeseries
  4. Multitenancy
  5. Multi-layer security
  6. Active-passive, Active-Active deployment support
  7. Redis on Flash support
    such many better feature and always run on latest Redis version. give a try
