Introduction to PaaS

PaaS is a type of cloud computing product in which a service provider provides
customers with a platform that enables them to build, operate and manage
business applications without the infrastructure needed for such software
development. Because the underlying infrastructures are not seen by developers
and other users, the PaaS Architectures are similar to serverless principles, where
a cloud service provider owns, operates the server and controls resource
allocation.

What is PaaS?

Platform as a service (PaaS) is a cloud-based development model that enables the
user to deliver starting from simple applications needed in day-to-day life to
centralized applications required for big organizations.

o The working procedure of PaaS is to provide a smooth working principle
in the cloud that includes the entire application development phase in the
cloud.

o In the PaaS cloud computing platform, the cloud service provider at the
back end handles scalability and the end-user does not have to worry about
managing the infrastructure.

o With the help of PaaS, we also get additional resources, including database
management systems, programming languages, libraries, and various
software development tools that works on cloud and made our daily life
better.

o PaaS has varieties of usefulness and among them, it cuts down the price
and headache of installing extra software licenses, core application, and
other platform resources.

o PaaS architectures used to hide their underlying infrastructure from
developers and other end users. As a result, the model becomes a serverless
computing model and function-as-a-service architectures where the cloud
service provider manages and runs the server and controls the distribution
of resources.

o It helps us to organize and maintain useful applications and services
whereas third-party providers maintain every other service in the cloud.
