Explanation:

Platform-as-a-Service

The capability provided to the consumer is to deploy onto the cloud infrastructure consumercreated or acquired applications created using programming languages, libraries, services, and
tools supported by the provider. The consumer does not manage or control the underlying cloud
infrastructure including network, servers, operating systems, or storage, but has control over the
deployed applications and possibly configuration settings for the application-hosting environment.
PaaS is also used as an application development environment, offered as a service by the cloud
service provider. The consumer may use these platforms to code their applications and then
deploy the applications on the cloud. Because the workload to the deployed applications varies,
the scalability of computing resources is usually guaranteed by the computing platform,
transparently. Google App Engine and Microsoft Windows Azure Platform are examples of PaaS.
