What is cloud computing in OpenStack?
Cloud computing in simple terms is using servers and storage and processing resources instead of buying and maintaining them physically.
There are three main types of services offered in Cloud environments:
- IaaS (Infrastructure As A Service): In this type of service, you get the infrastructure you need, such as servers, RAM, hard drives, etc., from a cloud service provider online.
- SaaS (Software As A Service): In this type of service, instead of installing and running software, you use it online through a web browser.
- PaaS (Platform As A Service): In this type of service, you get an online software platform to develop and run your applications.
