What is PaaS?

Like IaaS, PaaS also provides servers, storage along with software frameworks, middleware, development tools, operating systems and more. As a consumer, we are only responsible for managing hosted applications and services.

  • PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing and updating.
  • PaaS helps us to create an application by managing the underlying infrastructure.
  • It provides a development and deployment environment in the cloud as cloud provider takes care of underlying infrastructure.
  • Billing:- We pay only for the resources we use (pay-as-you-go).
    • No upfront costs:- Upfront costs are those which we pay even before the good is produced or service is performed. No upfront fee to be paid in IaaS as we pay only for the resources we use.

What PaaS consists of?

  1. Physical Infrastructure: data centers, servers, storage, network equipment.
  2. Middleware:- operating systems, libraries, languages, frameworks, tools for building apps.
  3. User interface:- a graphical user interface (GUI), a command-line interface (CLI) or both.

Advantages of PaaS

  • Manages application lifecycle efficiently:- building, testing, deploying, managing and updating within the same integrated environment.
  • As the development environment is accessed over the internet, teams can work together on projects even when they are in different locations geographically.
  • Add development capabilities without adding staff. As PaaS components can give your development team new capabilities without your needing to add staff having the required skills.
  • We can use the provided tools affordably as there is no need to purchase completely. We only pay for what we use.
  • PaaS can cut the time it takes to code a new app as PaaS comes with pre-coded application components built into the platform, such as workflow, directory services, security features, search and so on.

When you should choose PaaS?

  • When a company has legacy applications that cost a lot to keep in operation. They wish to reduce the cost of operations but do not expect to change the applications much.
  • When you have a team who can create and deploy apps.
  • PaaS provides a framework that developers can build upon to develop or customize cloud-based applications.

There are many other such scenarios where you can choose PaaS instead of IaaS and SaaS. PaaS can be a good option for startups and growing businesses as it reduces cost and difficulty in setting up and managing infrastructure.
