What is Amazon EC2 and how does it work?

Amazon Elastic Compute Cloud, commonly known as Amazon EC2, is a core service offered by Amazon Web Services that provides resizable compute capacity in the cloud. Essentially, it allows users to rent virtual servers, known as instances, to run their applications without the need to invest in physical hardware. This service is designed to simplify the cloud computing process, making it accessible for both individuals and large enterprises. To understand how Amazon EC2 works, it is essential to know that users can choose from a variety of instance types with varying configurations of CPU, memory, storage, and networking capacity. This flexibility enables users to select an instance type that best fits their application needs. Users can launch instances quickly and in a scalable manner, which means they can increase or decrease their computing resources depending on demand. When a user wants to launch an instance, they can select an Amazon Machine Image, or AMI, which serves as a template containing the operating system and application software needed. Users can also define network and security configurations, including firewalls and access control lists. After launching an instance, users can connect to it just as they would with any other server, using secure protocols such as SSH or RDP. One of the key features of Amazon EC2 is its pricing model, which is based on a pay-as-you-go structure. This means that users are billed for the compute time they consume, allowing for cost efficiency and predictability. Additionally, Amazon EC2 supports various features such as auto-scaling, load balancing, and integration with other AWS services, enhancing its value as a versatile cloud computing solution.
