IaaS, PaaS, and SaaS are the three most popular types of cloud service offerings. They are sometimes referred to as cloud service models or cloud computing service models. The digital cloud is a dense group of computer systems that work together as a giant computing resource. Traditionally, there are three main delivery models for cloud computing: SaaS, PaaS, and IaaS.
These delivery models allow your organization to take advantage of the benefits of cloud computing while minimizing the internal resources needed to manage them on your own. To learn more about the three cloud computing models, see the following infographic. Infrastructure as a Service (IaaS) is a self-service model for managing remote data center infrastructures. Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS) are the three service models of cloud computing, each designed to meet specific business requirements.
Platform-as-a-Service (PaaS) allows organizations to create, run, and manage applications without IT infrastructure. Cloud computing services offer shared resources, such as servers, databases, and networks, over the Internet. Cloud computing also provides more abstract services, such as access to analytical engines and business intelligence platforms. It is the most flexible of the three cloud computing service models, providing the customer with almost total control of the infrastructure.
The three main models of cloud computing services are infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Parallels RAS is multi-cloud ready and is compatible with Amazon Web Services (AWS), Azure and Google Cloud Platform, among other cloud services. SaaS solutions are the easiest of the three cloud computing service models to implement, as they are primarily supported by the SaaS provider. Cloud service providers (CSPs) have developed models of cloud computing services that provide different types of IT resources and support.
Software as a service (SaaS) replaces traditional software embedded in the device with software that is licensed on a subscription basis.
