1.3.3 Describe Platform as a Service

Description of PaaS.

PaaS

PaaS is a middle ground between renting datacenter space, and paying for a complete deployed solution. Here, the cloud provider maintains the physical infrastructure, physical security, internet connection, OS, middleware, dev tools and business intelligence services. In this setup, you don't need to worry about licensing or patching for operating systems and databases. PaaS is suited to a complete dev environment without maintaining the dev infrastructure. See the shared responsibility model for visual.

Scenarios

• Development framework: allows developers to build on or develop customize cloud based applications. Cloud features like scalability, availability and multi-tenant capability are all included, reducing the amount of coding required.

• Analytics or business development: tools provided as a service allow organizations to analyze and mine their data.
