Preface – This post is part of the Cloud Computing series.

Introduction

PaaS removes the need to manage underlying infrastructure (usually hardware and operating systems) and allows you to focus on deployment and management by providing you with software and hardware tools. These help you be more efficient as you don’t need to worry about resource procurement, predicting future requirements, software maintenance, patching, or any other heavy lifting involved in running your application.

It easily allows us to create, run, and post web applications. You can buy any platform as a service from the cloud at a meager cost and start your deployment journey without any upfront cost. And the end-user does not have to worry about management, security, and scalability because the cloud manages everything, so you can focus more on your business. Small firms have never been able to build robust development environments on-premises earlier in traditional computing methods. But now, it is possible as PaaS provides a path for accelerating software development.

Examples of PaaS

The most popular examples of PaaS are:

• AWS Elastic Beanstalk
• Windows Azure
• Heroku
• Force.com
• Google App Engine
• OpenShift

Facebook is an example of PaaS. Developers can create specific applications for the Facebook platform using APIs (Application Programming Interface) and make that application available to any Facebook user.

Platform as a Service Features

Database PaaS providers provide various databases such as ClearDB, AzureSQL Database, PostgreSQL, MongoDB, and Redis to communicate with the applications. And the programming languages used here are SQL. These databases are fully managed and secure and have backup options when needed. A cloud-based SQL service is the ideal way to increase database efficiency in your IT world.

1. Application Framework

It is a type of framework which help users quickly understand and design their applications. It has some pre-defined classes for faster development. It’s a platform responsible for control across the software life cycle, works at high speed, and collaborates with other frameworks. WordPress, Spring, Play, Rack, and Zend are popular frameworks.

2. Programming Languages

PaaS has enabled us to use many programming languages like C, C++, Ruby, Java, etc., which help us code and design different websites and applications.

3. Deployment

It provides various tools for deploying our application and software to be visible to everyone. It also has scalable solutions to automatically scale resources up or down according to the need. The cloud deployment model comprises four types: private, public, hybrid, and community.

Deep knowledge about Platform as a service and its factors

Advantages of Platform as a Service (PaaS)

1. Low Management

Clients need not worry about management because it is all the responsibility of the cloud to manage the services provided.

2. The lower total cost of ownership

Customers need not purchase expensive hardware, servers, power, and data storage. It saves their money, and now they can focus more on their business.

3. Scalable solutions

It is straightforward to automatically scale the resources up or down based on their demand.

4. The speed at its peak

PaaS services offer a very high speed of app creation, which saves developers a lot of time. There is no need to spend time setting and maintaining core infrastructure.

Conclusion

The PaaS model consists of the framework and application part of the cloud. It consists of many benefits, as discussed in the article. Many big companies and industries have adopted the PaaS model for switching their business to the cloud.
