The 7 Main AWS Services

For cloud applications, Amazon offers a wide range of services. Here are the top AWS ecosystem services, along with a quick explanation of how developers use them.

1. Compute Service

This service aims to assist developers in building, testing, and deploying applications within the cloud platform.

AWS EC2: This service lets users find and rent virtual machines and scale when required.

Developers can choose from various instance types, allowing them to choose the CPU, memory, storage, and networking capabilities necessary for their applications.

AWS Lambda: Among the serverless computing, the option is AWS Lambda. It is also in charge of running application code.

It enables you to run an application without having to deal with managing servers.

2. Storage

To archive data, WS offers a web data storage service. Additionally, disaster data recovery with excellent durability is a major benefit.

Amazon S3: Amazon S3 is an open cloud-based storage service created for online data storage.

It also provides storage on a web-based services interface and focuses on simple developers’ computing tasks.

Amazon EBS: Amazon offers a huge storage capacity for persistent data. EBS is usually used for primary data storage such as database, block-level, and file storage.
