    Study Notes

    Cloud Computing Definition and Characteristics

    • The National Institute of Standards and Technology (NIST) defines cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources.

    Cloud Computing Characteristics

    • On-demand self-service: computing resources can be provisioned and de-provisioned automatically
    • Broad network access: resources are accessible over the network from any device
    • Resource pooling: provider's computing resources are pooled together to provide a multi-tenant environment
    • Rapid elasticity: computing resources can be rapidly scaled up or down
    • Measured service: usage of computing resources is metered and billed accordingly

    Cloud Deployment Models

    • Cloud computing can be hosted in a public cloud, private cloud, hybrid cloud, or community cloud

    Value Proposition of Cloud Computing

    • One of the value propositions of cloud computing is the reduced capital expenditures (CapEx) for startup companies, as they do not need to invest in purchasing and maintaining their own hardware and software

    Minimizing Startup Costs

    • Cloud computing helps in minimizing startup costs by eliminating the need for upfront capital expenditures (CapEx) on hardware and software, allowing companies to allocate their resources more efficiently
