Which service provides lowest latency in terms of data acess on AWS?Answer choicesSelect only one optionREVISITEBSS3EFSSagemaker

The service that provides the lowest latency in terms of data access on AWS is EBS (Elastic Block Store).

Here's why:

1. EBS: Amazon Elastic Block Store (EBS) 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. EBS volumes offer the consistent and low-latency performance needed to run your workloads.

2. S3: Amazon S3 (Simple Storage Service) is an object storage service that offers industry-leading scalability, data availability, security, and performance. However, it is not designed for low latency access.

3. EFS: Amazon Elastic File System (EFS) provides a simple, scalable, fully managed elastic NFS file system for use with AWS Cloud services and on-premises resources. It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files. However, it also does not provide as low latency as EBS.

4. Sagemaker: Amazon SageMaker is a fully managed service that provides every developer and data scientist with the ability to build, train, and deploy machine learning (ML) models quickly. It is not a storage service and thus not relevant to the question of data access latency.

So, among the options provided, EBS offers the lowest latency for data access.
