Cloud computing provides on-demand access to computing resources like processing power, storage, and applications via the internet on a pay-as-you-go basis. It allows developers and IT departments to avoid undifferentiated work like procurement, maintenance, and capacity planning. There are three main types of cloud computing models - Infrastructure as a Service (IaaS) which provides basic computing resources, Platform as a Service (PaaS) which removes the need to manage underlying infrastructure, and Software as a Service (SaaS) which provides complete software packages managed by the service provider.

control over IT resources.
• Similar to existing IT resources, IT departments and
developers are familiar with.

9. Platform as a Service(PaaS)
• Remove the need for organisations to manage underlying
infrastructure(hardware and OS).
• User/Organisations Focus on the deployment and
management of applications.
• Takes care of:
– resource procurement
– capacity planning
– software maintenance
– patching
– any other issues. CODROIDHUB_ CLOUD COMPUTING-1

10. Software as a Service(SaaS)
