ElastiCache
AWS offers services to handle the cache management process. Earlier, we were using Memcached or Redis installed on VM, which was a very complex and tough task to manage in terms of ensuring availability, patching, scalability, and security.
On AWS, we have this service available as ElastiCache. This gives you the option to use any engine (Redis or Memcached) to manage your cache. It's a scalable platform that will be managed by AWS in the backend.
ElastiCache provides a scalable and high-performance caching solution. It removes the complexity associated with creating and managing distributed cache clusters using Memcached or Redis.
Now, let's look at how to secure ElastiCache.
Securing ElastiCache
For enhanced security, we deploy ElastiCache clusters inside VPC. When they are deployed inside VPC, we can use a security group and NACL to add a level of security on the communication ports at network level.
Apart from this, there are multiple ways to enable security for ElastiCache.
