Platform as a Service (PaaS)
Cloud Services Comparison
Perfect for businesses that want to create, test, and develop applications in the cloud. Cloud Platform as a Service (PaaS) allows businesses to buy the computing resources they need when they need them by the minute, hourly or on a monthly basis. PaaS includes everything from network to operating system (OS), middleware, servers, storage, and virtualization.
What is Cloud PaaS?
Platform as a Service (PaaS) is a category of cloud computing that delivers applications over the Internet. With PaaS, the cloud provider delivers both hardware and software – usually those needed for application development to its clients as a service.
A PaaS provider hosts all hardware and software on its own infrastructure. As a result, PaaS frees users from having to acquire and manage hardware and software to develop or run new applications. Cloud PaaS does not replace an organizations’ infrastructure. Instead, clients rely on PaaS providers for key services, such as Java development or application hosting. For example, deploying a typical application locally may require an IT team to buy and install hardware, operating systems, middleware (such as databases, web servers) to the actual application, define user access or security, and then add the application to existing systems management or application performance monitoring (APM) tools. IT must then maintain all of those resources over time. A PaaS provider, however, supports all of the underlying computing and software resources, clients only need to login and start using the platform – usually through a web browser interface.
Most PaaS platforms are geared toward software development, and they offer developers several advantages. For example, PaaS allows developers to frequently change or upgrade operating system features. It also helps development teams collaborate on projects. Users typically access PaaS through a web browser. PaaS providers then charge for that access on a per-use basis. Some PaaS providers charge a flat monthly fee to access the platform and the apps hosted within it. A few examples of PaaS providers include Force.com, Google App Engine, OpenShift, and Microsoft Azure.
Why Would You Use Cloud PaaS?
Cloud PaaS empowers businesses to create and launch new applications on the fly in test environments and production in a matter of minutes. PaaS provides computing resources on the fly and allows businesses to scale those resource up or down based on their present requirements.
Benefits of Cloud PaaS?
Cost Savings: Increases savings by reducing costs associated to purchasing hardware and software. It also helps organizations avoid the costs associated with ensuring up-time, maintaining hardware, and networking equipment or replacing old equipment.
Flexibility: PaaS provides added flexibility to launch new applications quickly into development or production environments.
No Hardware: It eliminates the need for costly hardware and technology refreshes. It shifts spending from a capital expenditure (CapEx) to operating expenditure (OpEx) and allows organizations to spend capital on their business.
No Single Point of Failure: Most PaaS providers offer replication and redundancy. If one server fails the service would be unaffected as there would be a remaining hardware resources and redundant configurations.
Not Location Dependent: In the event of a natural disaster or a power outage at your company, keeping servers housed there can be very problematic if they are suddenly unavailable to customers. PaaS allows companies to house their data elsewhere where it wouldn’t be affected if something happened where the business was located.
