What is a managed service delivery model? The delivery model for managed services depends on the type of service being managed or delivered. For example, cloud models typically include three types of delivery models:
PaaS (Platform as a Service)
Software as a Service (SaaS)
Infrastructure as a Service (IaaS)
Here's what you need to know about each model and the benefits it can bring to your business.
PaaS
In the PaaS software delivery model, developers rent everything they need to build a specific application. A cloud provider is required to provide access to the operating system, infrastructure and development tools.
PaaS is known to simplify web application development. From a developer's point of view, the entire backend management process happens behind the scenes. Although PaaS looks similar to serverless computing, there are many differences between the two.
Examples of PaaS include Magento Commerce Cloud, Force.com, Stratos, Apache Stratos, OpenShift, Windows Azure, and Heroku.
software as a service
SaaS is a software delivery model in which a third-party service provider is responsible for hosting the application. A provider is a person who provides these applications to customers over the Internet.
SaaS is considered closely related to on-demand computing software and application service provider (ASP) software delivery models. As with ASP, this model involves a provider that hosts the client's software and then delivers it to authorized end users over the Internet.
