Cloud Computing is offered three different service models to address the unique set of requirements for any business. Based on the service types, Cloud Computing is classified as Software as a Service (SaaS), Infrastructure as a Service (IaaS) & Platform as a Service (PaaS).
Software as a Service (SaaS)
In the case of SaaS, the Cloud Providers offer users the end product, which could be an application or software that could be used directly or on a subscription basis. The Cloud provider looks after maintenance, infrastructure, management network security, data availability, and other essential components.
Infrastructure as a Service (IaaS)
In IaaS, users rent out the required IT Infrastructure from their Cloud provider, mainly on a pay-per-consumption basis. In this type of Cloud Service model, users don’t need to worry about infrastructure management, as the service provider will ensure the allotment of resources & their availability at all times.
Platform as a Service (PaaS)
In this form of Cloud Computing Service, Cloud providers offer users a pre-deployed platform. The users only need to manage their codes and applications over the provided platform, without the need for installing & working with the expensive IDEs.
