Amazon EC2 Overview
Amazon Elastic Compute Cloud (EC2) is a core Cloud Computing service provided by Amazon Web Services (AWS). It offers resizable compute capacity in the form of Virtual Machines, commonly referred to as Instances. By using EC2, developers can deploy Applications quickly without the need for physical hardware maintenance, making it a cornerstone of Infrastructure as a Service (IaaS).
Core Features and Flexibility
One of the primary advantages of EC2 is its wide range of Instance Types, which are optimized for tasks involving high CPU, large memory, or enhanced storage capabilities. These Instances can run various Operating Systems, including multiple distributions of Linux and versions of Windows Server. To manage traffic and ensure high availability, EC2 integrates with Elastic Load Balancing and Auto Scaling, which automatically adjusts capacity based on demand.
Storage and Networking
Data persistence for EC2 is typically provided by Amazon EBS (Elastic Block Store), which offers durable block-level storage. Networking is handled within an Amazon VPC (Virtual Private Cloud), allowing users to define their own virtual network topology. Security is maintained through Security Groups and IAM (Identity and Access Management) roles to control access to resources.
