What is cloud computing?
Cloud computing is when data and software services are stored and accessed over the internet. It does not save any information on your machine. It means that computer services like computers, data storage, networking, databases, etc., can be used whenever they are needed. The main purpose of cloud computing is to let many people use data centers.
Types of cloud computing:
- Public cloud: the resources and services are given by the third party and customers can avail it through the internet.
- Private cloud: the resources & services are managed by third party or in house specially for particular companies.
- Hybrid cloud: it is known as the combination of both private and public cloud types. Whether the services are run on a public or private network depends on many factors, such as how sensitive the data and apps are, any industry certifications and standards that must be met, etc.
