Developers Let's Try

P

latform as a Service or PaaS is a cloud computing

service model that reduces the complexity of building

and maintaining the computing infrastructure. It gives

an easy and accessible environment to create, run and deploy

applications, saving developers all the chaotic work such as

setting up, configuring and managing resources like servers

and databases. It speeds up app development, allowing users

to focus on the application itself rather than worry about the

infrastructure and runtime environment.

Initially, PaaS was available only on the public cloud.

Later, private and hybrid PaaS options were created. Hybrid

PaaS is typically a deployment consisting of a mix of public

and private deployments. PaaS services available in the cloud

can be integrated with resources available on the premises.

PaaS offerings can also include facilities for application

design, application development, testing and deployment.

PaaS services may include team collaboration, Web service

integration, marshalling, database integration, security,

scalability, storage, persistence, state management, application

versioning and developer community facilitation, as well as

OpenShift is Red Hat’s container application platform that brings Docker and

Kubernetes into play when deployed. With OpenShift, you can easily and quickly

build, develop and deploy applications, irrespective of the platform being used. It is

mechanisms for service management, such as monitoring,

workflow management, discovery and reservation.

There are some disadvantages of using PaaS. Every user

may not have access to the full range of tools or to the high-

end tools like the relational database. Another problem is that

PaaS is open only for certain platforms. Users need to depend

on the cloud service providers to update the tools and to stay

in sync with other changes in the platform. They don’t have

control over this aspect.

OpenShift

OpenShift is an example of a PaaS and is offered by Red

Hat. It provides an API to manage its services. OpenShift

Origin allows you to create and manage containers.

OpenShift helps you to develop, deploy and manage

applications which are container-based, and enables

faster development and release life cycles. Containers are

standalone processes, with their own environment, and are

not dependent on the operating system or the underlying

infrastructure on which they run.
