    Study Notes

    • Cloud computing allows deploying applications with multiple components and services working together, available to anyone worldwide.
    • Application instances can be easily scaled to handle increased or decreased loads and can be deployed in various locations.
    • Private clouds are self-managed by organizations, while public clouds are offered by third parties and accessible to the public.
    • Hybrid cloud deployment combines both private and public clouds.
    • Community clouds allow multiple organizations to share the cost of a private cloud.
    • Infrastructure as a Service (IaaS) allows users to rent hardware and deploy their own software, providing more control over data.
    • Software as a Service (SaaS) allows users to access software without installation or management, relieving them of responsibility for application and data storage.
    • Platform as a Service (PaaS) provides users with a platform to build their applications, reducing the need for extensive programming.
    • Internal clouds are self-managed and do not require additional payments for usage, while external clouds are managed by third parties and come with additional costs.
