What is Cloud Computing?

Cloud computing is the delivery of resources such as servers, storage, databases and networking over the internet under a "pay-as-you-go" model. Instead of buying physical hardware, you rent as much resource as you need.

Cloud Models

• IaaS: You rent the infrastructure and manage the system yourself.
• PaaS: An application development platform is provided; the operational burden is reduced.
• SaaS: You use ready-to-use software.
• It clarifies communication between teams.

The Benefit of the Cloud

The value of the cloud lies not in being "trendy" but in providing elastic capacity: it grows when traffic increases and balances costs when it drops. With the right setup, availability and security standards are raised.
