Solution
The best EC2 storage option for a research lab looking to optimize caching for its scientific computations application would be Amazon Elastic Block Store (EBS).
Here's why:
a. Amazon S3: This is a simple storage service that offers an object storage service. It's great for storing and retrieving any amount of data, but it's not ideal for caching purposes.
b. Amazon EFS: This is a file storage service for use with Amazon EC2. While it could be used for caching, it's not the most efficient option for this specific use-case.
c. Instance Store: This provides temporary block-level storage for instances. This storage is ideal for temporary data that changes frequently (like buffers, caches, scratch data, and other temporary content) or for data that is replicated across a fleet of instances. However, data in an instance store is not persistent through instance stops, terminations, or hardware failures.
d. Amazon EBS: This provides persistent block storage volumes for use with Amazon EC2 instances. EBS volumes are network-attached, and persist independently from the life of an instance. This makes it a great choice for an application that requires a database, file system, or access to raw block level storage.
So, for a scientific computations application that requires caching, Amazon EBS would be the most suitable choice.
