Final answer:
AWS Simple Storage Service (S3) is the recommended storage service for storing static images with internet access. It is scalable, reliable, secure, and allows for easy retrieval of data. Other options like ElastiCache, EBS, and EFS serve different purposes such as caching, block storage, and file storage respectively.
Step-by-step explanation:
If you need a storage service on AWS that is accessible from the internet and can store static images, AWS Simple Storage Service (S3) is the recommended solution. S3 is highly scalable, reliable, and secure. It is specifically designed to make web-scale computing easier for developers. AWS S3 is an object storage service that allows you to store and retrieve any amount of data from anywhere on the web. With S3, you also have the flexibility to control who can access your data as well as configure CORS to allow web applications to access your resources.
ElastiCache is more suitable for caching frequently accessed data to improve the performance of web applications. Whereas, Elastic Block Store (EBS) is block storage used with EC2 instances, and Elastic File System (EFS) is a scalable file storage used with AWS Cloud services and on-premises resources.
