Amazon Elastic Compute Cloud (Amazon EC2) provides highly scalable and flexible virtual computing environments. Amazon EC2 allows you to provision and manage virtual servers, known as Amazon EC2 instances, to meet a wide range of computing needs.
Amazon EC2 instances are virtual machines that can be customized with various configurations of CPU, memory, storage, and networking capabilities. You can choose from a diverse selection of instance types, ranging from lightweight, cost-effective options to powerful, high-performance instances, depending on your application requirements. This flexibility enables you to match your computing needs to optimize performance and cost-efficiency.
Additionally, Amazon EC2 offers a suite of features that empowers you to manage your compute resources effectively. These include the ability to quickly launch new instances, create custom machine images (AMIs) for rapid deployment, and scaling computing capacity up or down as needed.
You can access the features of Amazon EC2 using the AWS Command Line Interface (AWS CLI). To list the AWS CLI commands for Amazon EC2, use the following command.
