What is compute services?
Compute services are a type of cloud computing service that allows users to create and manage virtual machines and containers, and provide scalable computing power on demand. Compute services are used for running applications, processing data, and performing various computing tasks in the cloud.
Compute services provide users with the ability to quickly and easily create virtual machines or containers with the desired configuration, operating system, and software, and to scale these resources up or down as needed. Compute services also allow users to choose the type of hardware and resources they need, including CPU, memory, and storage, and to pay only for the resources they use.
Some of the popular compute services provided by AWS include Amazon EC2, AWS Lambda, Amazon ECS, and Amazon Elastic Beanstalk.
Amazon EC2 (Elastic Compute Cloud): This service provides resizable compute capacity in the cloud and allows users to create and manage virtual machines, known as EC2 instances, with a range of configurations and operating systems.
AWS Lambda: This service provides serverless computing and allows users to run code in response to events or on a schedule, without the need to provision or manage servers.
Amazon ECS (Elastic Container Service): This service provides a highly scalable, high-performance container orchestration service that allows users to easily run and manage Docker containers on a cluster of EC2 instances.
Amazon Elastic Beanstalk: This service provides an easy-to-use platform for deploying and scaling web applications and services developed with Java, .NET, PHP, Node.js, Python, Ruby, or Go.
Compute services are an essential component of cloud computing, and they enable businesses and individuals to quickly and easily access computing resources on demand, without the need for expensive and complex hardware and infrastructure.
What is EC2?
Amazon Elastic Compute Cloud (EC2) is a compute service provided by AWS that allows users to rent virtual machines (EC2 instances) on the cloud. EC2 provides scalable computing capacity on demand, allowing users to quickly and easily create, launch, and manage virtual servers in the cloud.
