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.
