Study Notes

Traditional Computing Model

  • Infrastructure is typically viewed as physical hardware requiring substantial space, staff, security, planning, and capital expenditure.
  • Involves significant upfront investments and lengthy hardware procurement cycles.
  • Capacity provisioning relies on estimated theoretical maximum peaks, often leading to resource inefficiencies.
  • Risk of under-provisioning results in lack of capacity, while over-provisioning incurs costs for unused resources.
  • Setting up new infrastructure demands time and resources, including hardware purchase, installation, and management.

Cloud Computing Advantages

  • Transforms the perception of infrastructure from hardware to software.
  • Promotes flexibility and scalability in resource management, reducing dependency on physical assets.

Cloud Computing Models

  • Infrastructure as a Service (IaaS):

    • Provides fundamental cloud IT building blocks like networking, computing, and storage.
    • Offers high flexibility and control, closely resembling traditional IT resources.
  • Platform as a Service (PaaS):

    • Minimizes the need to manage underlying infrastructure (hardware and OS).
    • Allows greater focus on application deployment and management rather than infrastructure.
  • Software as a Service (SaaS):

    • Delivers fully managed applications by service providers, requiring no maintenance effort from users.
    • Example includes web-based email services, where users engage without needing to manage servers or software updates.
