Cloud Computing: An Overview

 

☁️ Cloud Computing: An Overview

Cloud Computing is the delivery of computing services—servers, storage, databases, networking, software, analytics, and intelligence—over the internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

🔹 Types of Cloud Computing

  1. Public Cloud

    • Managed by third-party providers (e.g., AWS, Google Cloud, Microsoft Azure).

    • Resources are shared among multiple users.

    • Use: Hosting websites, data storage, app deployment.

  2. Private Cloud

    • Used exclusively by one organization.

    • Hosted either on-premises or by a third party.

    • Use: Highly secure data processing (e.g., banks, govt agencies).

  3. Hybrid Cloud

    • Combines public and private clouds.

    • Allows data and apps to move between environments.

    • Use: Flexible scaling, data sovereignty needs.

  4. Community Cloud

    • Shared by organizations with a common concern (e.g., compliance).

    • Use: Universities, government alliances.

🏢 Key Functions of Cloud Computing for Enterprises

  1. Data Storage and Backup

    • Secure, scalable, and remotely accessible.

  2. Software as a Service (SaaS)

    • Cloud-hosted apps (e.g., Microsoft 365, Salesforce).

  3. Platform as a Service (PaaS)

    • Development environments for app creation.

  4. Infrastructure as a Service (IaaS)

    • Renting virtual servers, networks, and storage.

  5. Disaster Recovery

    • Business continuity with automatic backups and failover systems.

  6. Collaboration & Remote Work

    • Teams can work simultaneously across the globe.
