Cloud Service Models

Each cloud computing service model offers completely different levels of control, flexibility, and management. This way, businesses can select the right service for their needs.

As cloud computing has grown in popularity, several different cloud service modelsĀ have emerged to meet the specific need of different users. The three main models are “Infrastructure as a Service’ (Iaas), “Software as a Service” (SaaS) and Platform as a Service (PaaS).

Software as a Service

The SaaS model will provide users with a complete product/application that is run in the cloud by a Managed Service Provider (MSP) such as Serval IT Systems. The cloud users will not manage the cloud infrastructure and platform where the application runs. Instead, the MSP will take care of installing and operating the applications in the cloud and cloud users can access the software from cloud clients. This eliminates the need for users to install and run the application on their own computers, which simplifies maintenance and support.

SaaS allows organisations to reduce IT operational costs by outsourcing hardware and software maintenance and support to a cloud service provider. Therefore, organisations can reallocate IT operational costs away from hardware and software spending and personnel expenses, towards meeting other goals. Additionally, with applications hosted centrally, updates can be released without the need for users to install new software.

Infrastructure as a Service

The IaaS model is where an MSP will provide and manage virtualised infrastructure for users over the internet/”cloud” from its data centres. It is one of the most fast-growing models of cloud computing.

IaaS can be easily and quickly scaled up and down with demand, letting you only pay for what you use. Using cloud service models of this form allow organisations to avoid the expensive costs and complexities that come with of buying and managing your own physical servers and data centre infrastructure.

Platform as a Service

The PaaS model is a cloud base where users can develop, test and organise the different applications for their business. Using cloud service models in this form simplifies the process of enterprise software development. The resources for PaaS are offered in the form of servers, storage and networking which are managed by either the company or a platform provider.

PaaS resources can be purchased from a provider on a pay-as-you-go basis and are accessed over a secure Internet connection. This form of cloud service model helps organisations save money and time on buying and managing software licenses, underlying application infrastructure and other necessary tools.
