Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. The architecture of Amazon EC2 is designed to provide developers with a flexible and scalable computing environment for their applications.
The following components are involved in the architecture of Amazon EC2:
Regions: Amazon EC2 is available in different regions across the world, which consist of multiple availability zones.
Availability Zones: Each region contains multiple availability zones (AZs). An AZ is a data center that is designed to be isolated from failures in other AZs to ensure high availability and fault tolerance.
Instances: An instance is a virtual machine (VM) that runs in the Amazon EC2 environment. The instance type defines the hardware resources that are allocated to the instance, such as CPU, memory, and storage.
Amazon Machine Images (AMIs): An AMI is a pre-configured virtual machine image that is used to create instances. The AMI contains the operating system, application server, and any other software required for the application to run.
Elastic Block Store (EBS): EBS provides block-level storage volumes that can be attached to EC2 instances. EBS volumes are used for storing persistent data, such as databases and file systems.
Elastic IP addresses: An Elastic IP address is a static IP address that can be assigned to an EC2 instance. This allows the instance to maintain a consistent IP address even if it is stopped and started again.
Security Groups: Security groups are used to control access to EC2 instances. They act as a virtual firewall, allowing or denying traffic based on the rules that are defined.
Elastic Load Balancers (ELBs): ELBs are used to distribute incoming traffic across multiple EC2 instances. This improves the availability and scalability of the application.
Overall, the architecture of Amazon EC2 provides a flexible and scalable environment for running applications in the cloud. The ability to easily provision and scale instances, as well as use a variety of storage and networking options, makes Amazon EC2 a popular choice for hosting applications in the cloud.
