Platform as a service (PaaS) is a category of cloud computing services that provides a computing platform with a subset of software systems.
Clients of PaaS create their own software using the software tools delivered by the cloud services vendor. PaaS is a cloud computing service designed to give the client maximum control over software development and platform management.
In summary, PaaS is for clients who want to facilitate applications without the complexity and cost of buying, managing and maintaining the underlying hardware architecture and software needed for a powerful computing platform. PaaS typically includes an operating system, a programming language execution environment, a web server and a database. Examples of PaaS that you may have heard of include Heroku, Force.com and Google App Engine.
Why Platform as a Service is important
PaaS is designed for companies who have either an application or a set of applications and wants to deploy those applications over the cloud. In this situation, a PaaS provider with computer programming compatibility is the best solution. This gives you the following opportunities:
- Reduce your setup costs. All software developments require a combination of programming language, design and system administration abilities. If your business project requires an integrated environment, someone will have to buy, build, design, manage and maintain the components for your application. Neither the work nor the components not provide for any distinguishing features of your software—they are simply required. You can avoid those setup and ongoing maintenance costs with PaaS.
- Maintain control over your architecture. Even while your architecture is provided by a cloud vendor, you still retain control over configuration and management. This is a big advantage when developing and deploying your own application.
- Increase the speed of your application deployment. Without having to set up your own hardware and software to create your own platform, you can immediately continue with the process of developing your application or applications.
- Generate productivity and innovation. The PaaS system promises to free your operations from the mundane management and maintenance while freeing up your team or employees from the maintenance work so that they can focus on innovative software development and improvements which are likely the heart of your business.
- Easily deploy a scalable service. PaaS is typically a scalable subscription service that allows for substantial cost savings on what is likely the basis of your revenue generation (for clients using PaaS). This way you can grow your application quickly with a powerful platform to grow with your needs.
Challenges of Platform as a Service
- Objections from those who do not have trust in cloud services. Whether it’s for internal or public use, not all members of your business may be comfortable putting their faith into an outside company to provide the platform for your custom company applications.
- Disagreements over how to implement PaaS. When it comes to cloud services, not everyone in your company will always agree on a single service. Furthermore, because of the requirements for software environment development, you could get bogged down in debate of which PaaS provider is correct for your business.
- Finding the the right PaaS provider. As previously indicated, there are many different types of PaaS providers. Finding the right solution is extremely important; you don’t want to find yourself locked into an expensive contract when your requirements have changed. The accompanying services offered with PaaS are highly dependent on the cloud services vendor. All PaaS providers offer application hosting and deployment. However, additional integrated services and levels of scalability vary greatly from vendor to vendor.
- Proprietary lock-in. If your application needs run on the language required by the PaaS provider, or if your provider has provided customisation to services, you could find yourself getting locked in to a single provider. This often is an expensive exercise–only slightly less expensive than breaking away from the provider.
Three keys to successfully implementing Desktop as a Service
Successfully implementing PaaS involves fully understanding your requirements—including future requirements—as well as understanding what services comes with each provider. Here are the three keys to a successfully implementing your PaaS:
- Carry out a thorough analysis of your software requirements
- Create a shortlist of the best-perceived PaaS providers for your need
- Chat with each organisation’s IT experts to determine the best implementation strategy
Carry out a thorough analysis of your software requirements
As a business decision maker, you must fully understand the requirement of your custom software and your future application development. This is the only way you will be able to align your needs with the products offered by particular PaaS.
Choose the best cloud services provider to implement your PaaS
The best way to select a PaaS provider is to compare your list of possible PaaS providers in your region and create a shortlist. Discussions within your company and with IT experts will be essential in choosing your PaaS vendor.
Discuss your options with IT experts
Because of the nature of software development and the specific development required for each, it is important that the IT experts involved in any PaaS solution are fully aware of your current and future requirements. You need to deal with a company that will provide you with a flexible solution without selling you their product (which can often sound the same during meetings).
