Open–source cloud is a cloud service or solution built using open–source software and technologies. This includes any public, private or hybrid cloud model providing SaaS, IaaS, PaaS, or XaaS built and operated entirely on open–source technologies.
The best example of open source Cloud Computing is OpenStack.

This is one of the most frequently asked cloud computing interview questions.

Cloud computing lets us store and access our applications or data over remote computers instead of our computer. First of all, the cloud is just a metaphor for technology. Cloud data centers might be anywhere globally; we can also access them from anywhere with an Internet-connected device. It has the following benefits as given below:

Pay-per-use model: We only have to pay for the services we use.
24/7 Availability: It is always online! There is no such time that you simply cannot use our cloud service; you’ll use it whenever you would like.
Easily Scalable: it’s effortless to proportion and down or turn off as per customers’ needs. For instance, if your website’s traffic increases only on Friday nights, you can opt for scaling up your servers that particular day and then scaling down for the rest of the week.
Security: Cloud computing offers excellent data security. Especially if the data is mission-critical, then that data can be wiped off from local drives and kept on the cloud only for your access to stop it from ending up in the wrong hands.
Easily Manageable: You only have to pay subscription fees; the Cloud Provider entirely maintains all maintenance, up-gradation, and delivery of services. This is backed by the Service-level Agreement (SLA).
Cloud Computing Examples

Further, various places where Cloud Computing is applied as given below:

Big Data Analytics: Cloud computing helps businesses store and analyze many structured, semi-structured, and unstructured data to find underlying relationships. It is used to analyze customer buying patterns and use them for marketing and advertising campaigns.
File Storage: the most important advantage of cloud storage is that it’s virtually unlimited. Cloud storage will be available for nearly an equivalent or maybe a lesser price, which is 10 times quite your local storage.
Backup: Backup generally requires a storage unit where the data is secure and infinite storage is provided. Both can be achieved by using Cloud Computing.
