Simplifying Cloud Services: Understanding SaaS, PaaS, and IaaS in AWS

Infrastructure as a Service (IaaS)

  • Definition: Offers fundamental computing resources like virtual servers, storage, and networking over the internet.

  • AWS Example: Amazon EC2 (computing power), Amazon S3 (storage).

  • Importance: Provides scalable and flexible cloud computing resources.

  • Use Case: Hosting websites, backup and recovery, and big data analysis.

Platform as a Service (PaaS)

  • Definition: Provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining infrastructure.

  • AWS Example: AWS Elastic Beanstalk (application deployment and management service).

  • Importance: Simplifies web application development and deployment by automating infrastructure provisioning and management.

  • Use Case: Web and mobile application development.

Software as a Service (SaaS)

  • Definition: Delivers software applications over the internet, managed by the service provider.

  • AWS Example: Amazon Chime (communications service).
