Platform as a service, usually referred to simply as PaaS, is a kind of cloud computing provides a platform and environment to allow developers to build applications and services on the internet. PaaS services hosted in the cloud and accessed by users simply through their web browser. Platform as a service that allows users to create software applications using the tools provided by the vendor. PaaS services may include pre-configured features that customers can subscribe to; they can choose to include the features that meet their requirements while eliminating those that do not. Therefore, the package may be different from the framework provides point-and-click simplicity, where no storage expertise customers are required to provide the infrastructure options for advanced development . The infrastructure and management applications to customers and support available. The service is constantly updated, with the existing features and upgrades add features. PaaS providers can support the developers from conception of their original ideas to create applications, and through the testing and deployment. This was all achieved in a management mechanism. As with most cloud services, PaaS services are often paid for a subscription basis to end customers only pay for what they use. Customers also benefit from the economies of scale arising from the sharing of physical infrastructure between the user base, and can result in lower costs. Here are some of the features can be included to provide a PaaS: Operating System Server-side scripting environment management system database Server Software supports network storage tool for device access design and development of software developer Hosting, web developers and businesses can benefit from PaaS. Whether building an application that they are planning to offer software over the Internet or sold out of the box, the software developers can take advantage of a PaaS solution. For example, web developers can use the private PaaS environment at all stages of development, testing and finally held their website. However, businesses are developing their internal software can also use the platform as a service, especially for creating development and test environments separate ring fenced. Here are some benefits of PaaS for application developers: They do not have to invest in physical infrastructure; able to 'rent' virtual infrastructure benefits including cost and practical benefits. They do not need to purchase hardware or use your expertise to manage it. This makes them the freedom to focus on the development of applications. Moreover, customers will only need to hire the resources they need rather than fixed investment, capacity utilization and thus wasted. Make development possible for 'non-experts; with some PaaS services anyone can develop an app. They can simply do this through their web browser using one-click functions. striking example of this is one-click blogging software like WordPress installation. Flexible; customers can control which tools are installed in their platform and be able to create a platform suitable to their specific requirements. They can "pick and choose" the features they feel necessary. Adaptability; These features can be modified if circumstances dictate that they need. Teams in different locations can work work together, such as an Internet connection and web browser is all that is needed, the developers spread across multiple locations can work together on the construction applications. Protection, security provided, including data security and backup and recovery. in short, an offer PaaS provides an operating environment for application development. in other words, it provides the architecture as well as general infrastructure to support application development. this includes network services, hosting, software support and management. Therefore, ideal for the development of new applications for the site as well as mobile devices and computers.
