Platform as a Service
The rapid growth of IT industry continuously brings efficiency, innovation, and agility in IT operations. Organizations are fast approaching cloud computing to gain efficiency in development, testing and creating web applications to meet customer’s demands. Cloud platforms such as PaaS allow organizations to maintain proper balance between centralization and distribution of control. Centralization of control brings consistency, economies of scale, and efficient roll out of innovation while distribution of control allows agility and flexibility to organizations to respond quickly.
PaaS is an online platform where users can develop, run and manage web applications without the propriety of any complex infrastructure such as Software, Hardware, Middle-wares, Security, Database and Web servers. It gives users a cloud platform for developing, testing and running new applications without investing heavily in building infrastructure. A user needs to pay only the usage cost to service provider for using their cloud platform. Typically, PaaS allows self-service and self-provisioning of resources to support cloud architectures.
PaaS is helping the organizations in many ways:-
- It reduces time to market new application.
- It provides a platform for real time automated testing and development of applications.
- It provides common standards for developers to integrate with web services and databases.
- Reduced risk as organizations are not required to build & operate infrastructure to support their applications.
- PaaS provides flexibility to choose any tool already installed in platform and assists in setting up of customized platform if required.
However, like any other new technology, PaaS holds its list of challenges - security issues attached with cloud technology, vendor lock-in, integration with other application and standardizing developers work flows. PaaS extends businesses to multi-servers in vague geographical areas and there is always a concern for data access, authentication and authorization.
Today IT world is well out of the starting blocks with PaaS. The global PaaS market will top $6 billion by 2016 with growth rate projected to be over 48% per year for the next four years. Considering the size of the market and the projected growth rate, PaaS could be a driver of infrastructure business in near future.
