Platform as a Service

Platform as a Service (PaaS) is merely a method to hire operating systems, hardware, storage and network capacity on the web. This helps clients to run their existing applications or developing new ones. These services are a natural outgrowth of Software as a Serivce (Saas), which brought within the reach of clients many software applications on the web.

Apart from being cost effective, PaaS has many advantages. It allows upgrading and changing the essentials of operating systems, even as teams located in distant locations are able to contribute their services and knowledge for developing various software.

Google App Engine is a classic example of a PaaS. It is very easy to maintain and build applications through this engine, and after uploading your application, it can automatically take over all the functions. There is support for various programming languages such as Java, PHP, Python, apart from Go – which is a feature with run-time environments and natively compiles Go codes. The Go programming language itself was developed by Google and released in 2009.

As a Paas provider, Google App Engine has a number of other features that include storage sorting and transactions, automatic load balancing, accepting jobs outside the requests’ scope, scheduling various tasks. Users can also integrate the application projects with Google's other cloud computing services.

Applications running in the App Engine, are sandboxed and perform in a safe environment. It offers usage of all libraries accessed by the Engine, has tools to help you to upload your application and manage its various versions. Software Development Kits (SDKs) can be accessed through various computing languages. It is this kit which locally manages the application. The Administration Console is used to manage the application on the platform during the development process, also utilizes an interface for creating newer applications, configuring domains, examining logs, etc.

The downisde is that Google App Engine, as a PaaS, allows only 1 GB of data storage and transmission at no cost. The systems stability is safeguarded by imposing certain restrictions on the quotas even for paid services. Google App Engine has been of immense help to access various hardware, network and storage facilities for users.
