A university research department is deploying a multi-node cluster of Amazon EC2 instances to run a distributed genomic data analysis application. The application requires a shared, highly available file system that all EC2 instances can mount simultaneously to access research models, as well as high-performance, low-latency block storage attached to each individual instance to serve as boot volumes. Which two AWS storage services should the research department select to meet these requirements? (Select TWO).
- Amazon Elastic File System (Amazon EFS) to provide a shared, scalable file system that can be concurrently mounted by all EC2 instances in the clusterAnswer
- Amazon Elastic Block Store (Amazon EBS) to provide persistent, low-latency block storage volumes attached to each individual EC2 instance for boot systemsAnswer
- CAmazon Simple Storage Service (Amazon S3) to provide a local block storage drive that acts as the primary boot volume for each running EC2 instance
- DAWS Storage Gateway to provide high-performance local cache file shares that connect the cloud-based EC2 instances back to on-premises servers
- EAmazon S3 Glacier Flexible Retrieval to provide active file-level storage that supports simultaneous read and write actions with millisecond latency
Answer
Amazon Elastic File System (Amazon EFS) and Amazon Elastic Block Store (Amazon EBS)
The system requires a shared file system and boot storage for EC2 instances. Amazon Elastic File System (Amazon EFS) is the correct choice for the shared file system as it supports the NFS protocol and allows thousands of EC2 instances to connect concurrently. Amazon Elastic Block Store (Amazon EBS) is the correct choice for instance boot drives because it provides low-latency, persistent block storage volumes tailored for operating systems.
