title: AWS Elasticache - Redis Autoscaling
body: <p>There is an redis instance been created in ElasticCache and this will be used to store and retrieve data as usual.</p>
  <p>Is there any max memory for this redis instance and how can that be checked?</p>
  <p>All I need is say example if the data size in redis reaches above 100 mb then it should be auto scaled without me having to manually scale it or create a new instance and things like that.</p>
  <p>And when the data size is reduced(example: From 300mb to 50 mb due to less traffic) then the instances should be reduced so that there is no extra cost incured.
  How can this be configured in AWS ElastiCache?</p>
