Platform as a service (PaaS) is a category of cloud computing services that provides a computing platform and a solution stack as a service. Along with software as a service (SaaS) and infrastructure as a service (IaaS), it is a service model of cloud computing. In this model, the consumer creates an application or service using tools and/or libraries from the provider. The consumer also controls software deployment and configuration settings. The provider provides the networks, servers, storage, and other services that are required to host the consumer's application. PaaS offerings facilitate the deployment of applications or services without the cost and complexity of buying and managing the underlying hardware and software and provisioning hosting capabilities.

DBaaS
Platform as a Service (PaaS) is a way to rent hardware, operating
systems, storage and network capacity over the Internet. The service
delivery model allows the customer to rent virtualized servers and
associated services for running existing applications or developing
and testing new ones.

Cloud is reliable when it comes to the point “Deployment”. Many high-
end infrastructure companies serve a great deal of services.
Two such services that developers get for their easier development and
deployment are Compute Ecosystem and DBaaS.
We shall dive more into it further.*
* A basic and overall knowledge of the platform shall be discussed, rather than diving deep.
