    Study Notes

    Cloud Computing Fundamentals

    • Cloud Computing delivers computing services over the internet, providing access to resources and applications on-demand.

    • Major Cloud Computing Platforms: Notable examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), but not Dreamweaver.

    • Key Characteristics:

      • On-demand Self-service: Users can provision resources without human interaction.
      • Broad network access: Services accessible from various locations with internet connectivity.
      • Resource pooling: Providers serve multiple consumers with shared resources.
      • Rapid Elasticity: Resources can be quickly scaled up or down.
      • Measured service: Usage is tracked and billed accordingly.

    Cloud Computing Services

    • Infrastructure as a Service (IaaS): Providers offer basic computing resources, including servers, storage, and networking. Users manage their software and operating systems.

    • Platform as a Service (PaaS): Providers offer a platform for developers to build and run applications without managing infrastructure.

    • Software as a Service (SaaS): Providers offer ready-to-use applications accessed over the Internet, eliminating the need for users to install and manage them locally.

    Benefits of Cloud Computing

    • Scalability: Resources can be easily adjusted to meet fluctuating demand.
    • Cost efficiency: Pay-as-you-go pricing model reduces upfront investments and optimizes expenses.
