Amazon Web Services (AWS)

Amazon Web Services (AWS)

Definition

Amazon Web Services (AWS) is a comprehensive and widely adopted cloud platform offered by Amazon. It provides a range of services including computing power, storage options, and networking capabilities, allowing businesses and developers to scale and innovate efficiently.

Key Concepts

  • Elastic Compute Cloud (EC2): Virtual servers in the cloud for scalable computing capacity.
  • Simple Storage Service (S3): Object storage built to store and retrieve any amount of data.
  • Amazon RDS: Managed relational database service that supports multiple database engines.
  • Amazon VPC: Virtual private cloud to launch AWS resources in a logically isolated network.
  • AWS Lambda: Serverless compute service that runs code in response to events and automatically manages the compute resources.
  • IAM (Identity and Access Management): Securely manage access to AWS services and resources for users.

Detailed Explanation

  • Elastic Compute Cloud (EC2): EC2 provides resizable compute capacity in the cloud, making web-scale cloud computing easier for developers. Instances can be configured with different CPU, memory, and storage options.

  • Simple Storage Service (S3): S3 is designed for high scalability, data availability, and security. It can store and retrieve any amount of data at any time, serving as a foundational service for various AWS applications.

  • Amazon RDS: RDS simplifies the setup, operation, and scaling of a relational database in the cloud. It automates administrative tasks like hardware provisioning, database setup, patching, and backups.

  • Amazon VPC: VPC enables the creation of isolated networks within the AWS cloud. Users can control the IP range, create subnets, and configure route tables and network gateways.

  • AWS Lambda: Lambda allows running code without provisioning or managing servers. Users only pay for the compute time consumed, which makes it a cost-efficient solution for event-driven computing.

  • IAM: IAM enables fine-grained access control to AWS services and resources. It allows the creation of users, groups, and roles, with permissions to control access to specific services.
