The impressive capabilities of cloud computing, in particular private clouds, have given businesses the means to create and fully utilise secure customisable infrastructure platforms. Platform as a Service (PaaS) enables businesses to use services on-demand on a pay-as-you-go basis. Relieving businesses of costly expenditures such as hardware, software, essential upgrades, security programs, and storage backup, PaaS delivers platform resources as needed. Highly configurable, PaaS empowers users to focus on the deployment of business applications rather than the traditional complex on-site infrastructure.
A platform, such as Windows and Linux, is the operating system from which applications run. PaaS replaces the traditional method of purchasing and maintaining an expensive and complex application platform by creating a foundation on which to build and deliver applications and services entirely through the Internet. PaaS provides integrated solutions for application design and development, testing, hosting, and deployment for the life of web applications and services – from start to finish.
Designed for custom application testing and development, PaaS cloud hosting gives developers the resources they require at any given time. Spikes in traffic are instantly served by a storehouse increase within the underlying layers of the cloud infrastructure.
PaaS is the ideal solution for a variety of applications.
- Application design
- Application development, testing, and deployment
- Team collaboration
- Web service integration and marshalling
- Database integration
- State management
- Application versioning
- Application instrumentation
- Developer community facilitation
PaaS Cloud Hosting
Cloud hosting takes developing applications to the next level. Most secure UK data centres use servers and software specifically designed to take full advantage of the cloud computing concept, such as the virtualisation hypervisors vSphere from VMware and Hyper-V from Microsoft.
The following terms and definitions are used to describe the different types of PaaS hosting:
- Private cloud hosting: Private cloud hosting is a virtual cloud platform solely dedicated to a single enterprise. Multiple resources make up the dedicated cloud hosting infrastructure, ensuring reliability, scalability, and availability. In addition to the dedicated resources, private cloud hosting is immeasurably more secure than public, where resources are shared among different users
- Hybrid cloud hosting: Hybrid cloud hosting is a mix of private, public, and, often, local resources that work together to create a platform infrastructure. Hybrid hosting is an option for enterprises with an up-to-date environment in place, although, a move to private cloud hosting will likely occur in the future because of the cost of upgrading on-premise systems
Why the Cloud?
In the past, application developers were forced to purchase developer and server licenses, buy and maintain development hardware, install and update security and software programs, and spend hours testing before deploying an application. Cloud computing changes all of that.
Consider these PaaS cloud computing advantages:
- Java, ASP.NET, Python, and other platform developers can tap into the cloud and get right to work
- Users pay only for the resources used
- Redundant resources ensure the availability and scalability of any platform or application
- User and administrative accessibility is available worldwide
PaaS gives programmers and application developers the tools to develop more and spend less.
