Study Notes

Cloud computing allows organizations to access computing resources over the internet instead of managing their own data centers.
Private cloud refers to a cloud infrastructure that's exclusively used by one organization and not intended for external sharing.
Public cloud, on the other hand, is a shared infrastructure that can be accessed by multiple organizations or the general public.
Hybrid cloud is a combination of private and public cloud, where an organization uses both for different parts of their application or workload.
Community cloud is a type of private cloud where multiple organizations share the infrastructure and costs.
Infrastructure as a Service (IaaS) is a cloud deployment model where the provider offers virtualized computing resources over the internet and the end user is responsible for managing and configuring the operating system, applications, and data.
Software as a Service (SaaS) is a cloud deployment model where the provider offers applications over the internet and manages and maintains the underlying infrastructure, while the end user only manages their data.
Platform as a Service (PaaS) is a cloud deployment model where the provider offers a platform for developing, deploying, and managing applications over the internet. The end user is responsible for managing their application logic and data, while the provider manages the underlying infrastructure and middleware.
Salesforce is an example of a platform that offers a set of modules or building blocks for creating custom applications through Platform as a Service (PaaS).
