Cloud computing refers to delivering computing services — such as servers, storage, databases, networking, software, and analytics — over the internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale. Here's a quick breakdown:

Key Concepts

  • Definition: A model for delivering on-demand computing resources via the internet.

  • Service Models:
    • IaaS (Infrastructure as a Service): Virtualized computing resources (e.g., storage, servers).
    • PaaS (Platform as a Service): Development platforms (e.g., databases, middleware).
    • SaaS (Software as a Service): Ready-to-use applications (e.g., email, productivity tools).

  • Deployment Models:
    • Public Cloud: Shared infrastructure (e.g., AWS, Google Cloud).
    • Private Cloud: Dedicated infrastructure (e.g., for enterprises).
    • Hybrid Cloud: Mix of public and private clouds.
