PaaS: Software Vendors' Ticket to On-Demand
Platform as a Service (PaaS) is a metered on-demand infrastructure designed to host on-demand applications. “The PaaS model makes all of the facilities required to support the end-to-end life cycle of building and delivering web applications and services entirely available from the Internet — with no software downloads or installation for developers, IT managers or end-users. It’s also known as cloudware.”
Why PaaS? Why is it becoming popular?
- Decent web-based are becoming competitive to traditional desktop alternatives, like Microsoft’s Office products. Web apps like Google Apps, 30boxes, ThinkFree and Zoho have proved themselves to be effective and available whenever you are on-line.
- With the entry and success of the SaaS model, momentum has grown for vendors of all sizes to make their applications available on-demand.
- PaaS is more cost effective for small software vendors to seek out and partner with infrastructure providers when deploying their applications on-demand. Infrastructure providers have seen the need and have responded by building platforms that provide turn-key solutions to things like collaboration, multi-tenancy, concurrency, scalability, storage, failover and security
- Vendors also see cost reductions from from being able to directly access higher level programming abstractions that allow for the rapid creation services, user interfaces and other application elements.
