Amazon ElastiCache

Managed in-memory caching with Redis OSS, Valkey or Memcached for very fast data access.

What is Amazon ElastiCache?

ElastiCache runs in-memory data stores (Valkey, Redis OSS or Memcached) so your application can read frequently used data in microseconds instead of querying the database each time.

Key features

  • Serverless or node-based clusters
  • Replication and automatic failover
  • Data tiering for larger datasets
  • Encryption in transit and at rest
  • Online scaling

What it is used for

  • Caching database queries
  • Session storage
  • Leaderboards and counters

When to use it

  • Caching slow database queries
  • Session storage
  • Rate limiting and leaderboards

When something else fits better

  • As the only copy of important data without persistence
  • Very low-traffic apps that do not need caching

How pricing works

Serverless is charged for data stored and compute used; node-based clusters are charged per node-hour. Prices change and differ by region; we confirm current costs for your setup before you commit.

Equivalent on Google Cloud

The closest Google Cloud service is Memorystore: managed in-memory data store for Redis, Valkey and Memcached.

How DomainHostly helps with Amazon ElastiCache

  • Plan: choose the right setup, size and region for your workload and budget.
  • Set up securely: configure Amazon ElastiCache with least-privilege access, encryption and backups where they apply.
  • Migrate: move from shared hosting, your own servers or the other cloud with minimal downtime.
  • Run and optimise: monitoring, updates and regular cost reviews so you only pay for what you use.

Databases: Managed relational, NoSQL, in-memory and specialised databases.

What to consider: Databases

  • Pick relational databases for transactions and reporting, NoSQL for very high scale with simple access patterns.
  • Enable automated backups, point-in-time recovery and a standby replica for production.
  • Keep the database on a private network and never expose it directly to the internet.
