Types of Cloud
There are three cloud types:
- Public cloud: Here, the resources and services provided by third-party service providers are available to customers via the Internet.
- Private cloud: In a private cloud, the resources and services are managed in-house or by third parties, exclusively for a particular organization.
- Hybrid cloud: It is a combination of both public and private cloud types. The decision whether to run the services on public or private depends on some parameters such as the sensitivity of the data and applications, industry certifications and required standards, etc.
