EC2
Amazon EC2 (Elastic Compute Cloud) is a web service that provides resizable compute capacity in the cloud, allowing users to launch virtual servers, configure security and networking, and manage storage. It enables scalable deployment of applications by eliminating the need to invest in hardware upfront, offering a variety of instance types optimized for different workloads such as compute, memory, or storage-intensive tasks.
Developers should use EC2 when they need flexible, on-demand virtual servers for hosting web applications, running batch processing, or handling variable workloads without managing physical hardware. It is ideal for scenarios requiring quick scaling, such as e-commerce sites during peak traffic, development and testing environments, or data analysis pipelines, due to its pay-as-you-go pricing and integration with other AWS services.
