What is a primary use case for Amazon EC2?

The primary use case for Amazon EC2 revolves around running scalable virtual servers, particularly for web applications. Amazon EC2, or Elastic Compute Cloud, provides the ability to provision and manage virtual machines in the cloud. This service allows users to quickly scale resources up or down as needed, making it ideal for applications that may experience varying levels of demand.

For web applications, which often require flexibility to handle traffic spikes or decreased loads, EC2 offers features such as auto-scaling and load balancing. These functionalities enable a dynamic adjustment of computing resources based on real-time demand, ensuring optimal performance and cost efficiency. Additionally, users benefit from the wide range of instance types tailored to different performance requirements, further enhancing the suitability of EC2 for running diverse web applications.

While options like data backup and recovery or storage of large data sets are important functions, they are not primary use cases for EC2 specifically. Data backup and recovery typically rely on services designed for storage, such as Amazon S3. Hosting static websites is more aligned with services like Amazon S3 or Amazon Lightsail, which cater specifically to content delivery without the need for scalable backend infrastructure. Therefore, the emphasis on scalable virtual servers for web applications distinctly marks EC2's primary use case in the cloud computing
