    Study Notes

    Cloud Computing

    • Cloud computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics, intelligence, and more, over the internet.
    • It provides an alternative to on-premises data centers.

    On-Premise Data Centers

    • On-premise data centers require managing everything from purchasing and installing hardware to maintaining it through its entire lifecycle.
    • Advantages of on-premise data centers include:
      • Higher upfront cost
      • Storage capacity
      • Data backup capabilities
      • Total ownership of regulatory compliance responsibilities
    • Disadvantages of on-premise data centers include:
      • Reliability
      • Scanability
      • Ownership cost
      • Maintenance
      • Technical skills required

    Cloud Models

    • There are three types of cloud models:
      • Public Cloud: Cloud resources owned and operated by a third-party cloud service provider, delivering computing resources over the internet.
      • Private Cloud: Cloud computing resources exclusively used inside a single business or organization.
      • Hybrid Cloud: Combination of public and private clouds, allowing data and applications to be shared between them, providing flexibility and more deployment options.

    Cloud Services

    • There are three types of cloud services:
      • Infrastructure as a Service (IaaS): Renting IT infrastructures like servers, virtual machines, storage, networks, and operating systems from a cloud service vendor.
        • Provides maximum flexibility, but requires more effort in maintenance.
      • Platform as a Service (PaaS): On-demand environment for developing, testing, delivering, and managing software applications.
        • Reduces flexibility, but the cloud vendor manages the environment.
      • Software as a Service (SaaS): Centrally hosted and managed software services provided to end-users over the internet.
        • Minimizes operational costs, with examples including Microsoft One Drive, Dropbox, and WordPress.

    Advantages of Cloud Computing

    • Advantages include:
      • Compute power
      • High availability
      • Secure connection
      • Scalability
