A company has experienced high latency on its main application, affecting thousands of users daily. You have been hired to redesign the application and find that the company has been using a hybrid approach where the application is hosted on EC2 instances but the databases are hosted within the corporate network. After some research, you conclude that a first step to reducing latency is to use an in-memory cache service. Which of the following services best meets your needs?
Correct answer - "ElastiCache" : A managed service offering from AWS for in-memory data storages.
Incorrect:
"RDS" - Stores data on disk which has higher read latency
"DynamoDB" - Stores data on disk which has higher read latency
"Parameter Store" - Best suited for secrets and configuration information
