“The cloud services companies of all sizes…The cloud is for everyone. The cloud is a democracy.” – Marc Benioff
Platform as a Service or PaaS, is a cloud computing category, in which a PaaS provider provides a platform through which customers can develop, run, and manage applications without the complexity of maintaining the infrastructure that is associated with developing and launching an app.
Platform as a Service in cloud computing is quite useful for those associated with the IT industry – both sellers and customers. Along with SaaS and IaaS, the PaaS model is used by small businesses for developing and trading their own software and as other cloud business models, this too is a profit generating one, as can be seen in the image.
“By 2026, the revenue of vendors offering platforms-as-a-service in the public cloud market is predicted to reach a combined value of 68.3 billion U.S. dollars.”
PaaS simplifying complexity
PaaS provides a hassle free way to install in-house hardware and software to develop or run a new application. It does not replace the entire infrastructure of your business. Instead, a business relies on PaaS providers for various key services, such as application hosting or Java development.
For example, if you are using any local business tool, then you have to buy and install hardware, OS, middleware (such as databases, web servers and so on), define access or security to the user, and then add the application to existing performance monitoring (APM) tools. It’s not over, you should take care to maintain all of these resources over time.
However, a PaaS provider provides a platform through which customers can develop, run, and manage applications without the complexity of maintaining the infrastructure that is associated with developing and launching an app. To start using the platform, users only need to log in – through a web browser interface.
PaaS helps to do the following:
- Enable faster time to market.
- Enhance ability to react to changes and opportunities.
- As no upfront investment is involved, so you can spread your capital investments further and outshine the competition.
The diagram on the right shows a high-level view of the provider and customer roles for PaaS.
Most PaaS platforms are associated with software development, and they provide developers several advantages. (Windows Azure PaaS is one of them. It delivers a robust platform, allowing users to test, build, and deploy applications with ease, so that the enterprises can focus on the application, rather than managing complex computing resources.)
Let’s understand these cloud computing advantages one by one in detail:
Pay as you go method
Users only pay for the services procured, so there is not any wastage of resources. Pay-as-you-go method permits you to be charged only for what you use. Some PaaS providers charge monthly fee to access their platform and the apps. It is important to discuss pricing before engaging their services.
Speed, Flexibility and Agility
PaaS provides better flexibility, speed, and agility to the development process. By providing a predictable, application infrastructure, enterprises don’t get bogged down with enabling applications and can meet the customers’ e needs.
Scalability and Performance
Cloud can be scaled to meet your growing IT system requirements.
Regarding performance, it is the PaaS provider’s responsibility to ensure that customers’ services run without any hurdle and, also to provide them with the ability to access their resources via dashboards for better performance.
No backup overheads
Storage spaces and backups require costs for maintenance, power, and cooling, which all drain a company’s budget. These are not required with PaaS solutions, as PaaS eliminates the need for backup and storage. It will ultimately result in substantial savings.
High Network bandwidth
It’s very important for deployment process of a web app to perform testing to see how it performs in different frameworks. It often results in a network-wide slowdown, but with PaaS, the entire process of testing can be done on the cloud computing servers.
This is one of the biggest advantages provided by platform as a service in cloud computing. What all you need -an internet connection and a web browser, through which developers can work together across several locations anytime, on the same application build.
Zero software maintenance
PaaS in cloud computing provides all the management and upgrades of both hardware and software, so that the users can focus only on their business.
Benefits of PaaS across different roles
The below diagram shows the benefits of PaaS in cloud computing across different roles i.e. from IT department to architect, developer to builder, and CIO(Chief Information Officer)/LOB (Line of Business) to project manager.
PaaS platforms help you focus on code, not management, so you can build, test, and deploy applications without worrying about IT tasks or waiting for days to get servers ready for writing code. Also it’s helpful in those situations when multiple people work on a single project while being at different locations. Thus, benefits of cloud computing make your life in IT a lot more easier. Happy cloud computing!
