AWS Technical Essentials Practice

The selection of block storage, object storage, file storage, and archival storage accurately reflects the diverse range of storage options provided by AWS, catering to different use cases and requirements.

Block storage, such as Amazon Elastic Block Store (EBS), is optimized for use with compute instances, providing high performance and low latency for applications that require consistent I/O performance. It is commonly used for running databases or applications that need fast access to data.

Object storage, exemplified by Amazon S3, is designed to store and retrieve large volumes of unstructured data. It is highly scalable and provides features such as versioning and lifecycle policies, making it ideal for data backup, web content storage, and big data analytics.

File storage is represented by Amazon Elastic File System (EFS), which allows for scalable and elastic file storage that can be shared across multiple instances. It is useful for applications that rely on a shared file system, supporting use cases like content management, media processing, and web serving.

Archival storage, such as Amazon S3 Glacier, is aimed at long-term storage of infrequently accessed data at very low costs. This is suitable for data that is retained for compliance, backups, or archival purposes where immediate access is not critical.

Thus, the
