In the context of Cloud Computing, what is the full form of PaaS?
- A.Payment as a Service
- B.Platform as a Service
- C.Performance as a Service
- D.Protocol as a Service
Correct answer
Explanation
The correct answer is B, Platform as a Service. Cloud computing is sold in three service models, and PaaS is the middle one. A PaaS provider hands the developer a ready platform — the operating system, a runtime, a database, libraries and build tools — so an application can be written and deployed without buying or managing any hardware or patching an operating system. Google App Engine, Microsoft Azure App Service, Red Hat OpenShift and Heroku are examples. Below it, IaaS supplies raw computing power and storage, such as Amazon EC2, and the user still installs the software. Above it, SaaS delivers finished software over the browser, such as Gmail or Google Docs. The three main deployment models are public, private and hybrid cloud. Options A, C and D are wrong because Payment as a Service, Performance as a Service and Protocol as a Service are not cloud service models. Exam tip: IaaS gives the machine, PaaS the platform, SaaS the finished software.
