AWS Technical Essentials Practice

Amazon EC2, or Elastic Compute Cloud, is a fundamental component of AWS's infrastructure offerings. It provides scalable computing capacity in the cloud, allowing users to launch virtual servers, known as instances, to run applications and services. EC2 is crucial for users who require flexibility in their resource allocation, enabling them to quickly adjust compute resources up or down as their needs change. This service is integral to building cloud-based applications, accommodating everything from small-scale web hosting to large-scale enterprise solutions.

In contrast, the other options—Amazon Pay, Amazon Drive, and Amazon Prime—are not considered core AWS services. Amazon Pay is a payment processing service designed for e-commerce, while Amazon Drive is a cloud storage service intended for personal file storage. Amazon Prime is a subscription service that offers various consumer benefits, including streaming video and music. While these services are associated with the Amazon brand, they do not fall under the umbrella of core AWS services that directly support computing and infrastructure in the cloud.
