PaaS; Platform as a Service
Platform as a Service, often simply referred to as PaaS, is a category of Cloud computing that provides a platform and environment to allow developers to build applications and services over the Internet. PaaS services are hosted in the Cloud and accessed by users simply via their web browser.
Platform as a Service allows users to create software applications using tools supplied by the provider. PaaS services can consist of preconfigured features that customers can subscribe to; they can choose to include the features that meet their requirements while discarding those that do not. Consequently, packages can vary from offering simple point-and-click frameworks where no client-side hosting expertise is required to supplying the infrastructure options for advanced development.
With PaaS solutions from Certus, a SysGroup Company, the infrastructure and applications are managed for your business and support is available. Services are constantly updated, with existing features upgraded and additional features added.
Below are some of the features that can be included with a PaaS offering:
- Operating system
- Server-side scripting environment
- Database management system
- Server Software
- Network access
- Tools for design and development
Below are some of the benefits of PaaS:
- You don’t have to invest in physical infrastructure; being able to ‘rent’ virtual infrastructure has both cost benefits and practical benefits. They don’t need to purchase hardware themselves or employ the expertise to manage it. This leaves them free to focus on the development of applications. What’s more, clients will only need to rent the resources they need rather than invest in fixed, unused and therefore wasted capacity.
- Makes development possible for ‘non-experts’; with some PaaS offerings, anyone can develop an application. They can simply do this through their web browser utilising one-click functionality. Salient examples of this are one-click blog software installs such as WordPress.
- Flexibility; customers can have control over the tools that are installed within their platforms and can create a platform that suits their specific requirements. They can ‘pick and choose’ the features they feel are necessary.
- Adaptability; Features can be changed if circumstances dictate that they should.
- Teams in various locations can work together; as an Internet connection and web browser are all that is required, developers spread across several locations can work together on the same application build.
- Security; security is provided, including data security and backup and recovery.
In summary, a PaaS offering supplies an operating environment for developing applications. In other words, it provides the architecture as well as the overall infrastructure to support application development. This includes networking, storage, software support and management services. It is therefore ideal for the development of new applications that are intended for the web, as well as mobile devices and PCs.
