What is Application Platform as a Service (aPaaS)?
Application Platform as a Service (aPaaS) is also referred to as Platform as a Service (PaaS). It is one the most sought after cloud computing models in addition to Infrastructure as a Service and Software as a Service. It empowers users with all vital capabilities for application development including hardware, storage or network capacity, and operating systems, to name a few. It is used for development of new applications as well as running existing applications.
There are multiple examples of aPaaS model including EngineYard, VMForce, and GoogleApp Engine. Clients are offered hosted software applications at considerably low costs. Application can be easily developed and deployed due to its scalability and fault tolerance. It also facilitates concurrent working of geographically dispersed teams. Users are allowed to access its services irrespective of location and time.
In spite of such remarkable advantages, PaaS does have its own downside. There is an element of vendor lock in that must be kept in mind. PaaS is designed with developers in mind. It facilitates deployment of code with no need to worry about runtime, server infrastructure, or operating system. Developers are not required to own and maintain data centers and can simply build and deploy code. The payment method of pay-as-you-use is also very convenient and cost effective.
PaaS enjoys excellent popularity among developers since it is easy for them to focus all their efforts and concentration to development tasks, instead of bothering about execution and management aspects. Service providers of PaaS offer greater flexibility of scaling up or scaling down of CPU power in response to traffic. PaaS eliminates the need to separately purchase underlying hardware or software. It is one the most growing categories of cloud services. aPaaS offers a robust development platform for automating, configuring, and deploying the application in cloud.
