Which of the following is an AWS compute service?

Amazon EC2, or Elastic Compute Cloud, is indeed an AWS compute service. It provides scalable computing capacity in the cloud, allowing users to launch virtual servers, known as instances, on-demand. This flexibility means that you can quickly scale resources up or down based on your application's needs. EC2 enables users to run applications without having to invest in hardware upfront, offering various instance types tailored for different use cases, such as general-purpose computing, memory-optimized applications, and compute-optimized workloads.

In contrast, Amazon S3 (Simple Storage Service) is focused on object storage for data, making it ideal for storing and retrieving any amount of data from anywhere on the web. Amazon RDS (Relational Database Service) is a managed database service used for setting up, operating, and scaling relational databases in the cloud. Amazon VPC (Virtual Private Cloud) is a networking service that facilitates the creation of isolated network environments within AWS. Each of these services plays a vital role in the AWS ecosystem, but only Amazon EC2 directly falls under the category of compute services.
