AWS Technical Essentials 2025 – 400 Free Practice Questions to Pass the Exam

Amazon EC2 (Elastic Compute Cloud) is primarily designed to provide resizable compute capacity in the cloud. This service allows users to easily provision and manage virtual servers, known as instances, which can be scaled up or down based on demand. It enables organizations to quickly deploy applications, handle varying workloads, and optimize their resources according to their needs.

The ability to resize compute capacity is fundamental to cloud computing, as it provides the flexibility to accommodate spikes in traffic or to reduce resource usage when demand decreases. With EC2, users can select instance types tailored for specific tasks, configure networking, and choose operating systems, all while benefiting from the cloud's elasticity.

In contrast, resilient storage capabilities are more closely associated with services like Amazon S3 or Amazon EBS. Managed database services are provided by Amazon RDS and similarly named services, while cloud-based machine learning tools are offered under Amazon SageMaker and various AI services. Each of these other choices fulfills a different role within the AWS ecosystem, but they do not represent the primary function of Amazon EC2.
