Amazon MemoryDB: Azure equivalent
Microsoft states that Azure has no direct equivalent of Amazon MemoryDB.
Azure Managed Redis supports persistence (RDB or AOF) and high availability, but it's designed as a cache, not a durable primary database with a multi-AZ transaction log.

| Service | Amazon MemoryDB | No first-party equivalent |
| Lifecycle | Generally available | — |
| What it is | Durable in-memory database compatible with Valkey and Redis OSS. Writes go to a Multi-AZ transactional log, so it can serve as a primary database. | — |

Key differences
- MemoryDB commits every write to a distributed Multi-AZ transaction log before acknowledging it, so a failover loses no acknowledged writes. Redis persistence on Azure Managed Redis is periodic or append-only to disk and isn't intended as the system of record.
