There are three major cloud service models: software as a service (SaaS), infrastructure as a service (IaaS) and platform as a service (PaaS). Cloud service pricing models are categorized into pay per use, subscription-based and hybrid, which is a combination of pay-per-use and subscription pricing models. Software as a ServiceSoftware as a service vendors host the applications, making them available to users via the internet. With SaaS, businesses don't have to install or download any software to their existing IT infrastructures. SaaS ensures that users are always running the most up-to-date versions of the software. The SaaS provider handles maintenance and support. Platform as a ServicePlatform as a service offers developers a platform for software development and deployment over the internet, enabling them to access up-to-date tools. PaaS delivers a framework that developers can use to create customized applications. The organization or the PaaS cloud vendor manage the servers, storage and networking, while the developers manage the applications. Infrastructure as a ServiceInfrastructure as a service is used by companies that don't want to maintain their own on-premises data centers. IaaS provides virtual computing resources over the Internet. The IaaS cloud vendor hosts the infrastructure components that typically exist in an on-premises data center, including servers, storage and networking hardware, as well as the hypervisor or virtualization layer. How Do the 3 Cloud Computing Service Models Differ?The three cloud service models mainly differ in what they offer out of the box. SaaS is cloud-based software that companies can buy from cloud providers and use. PaaS helps developers build customized applications via an application programming interface (API) that can be delivered over the cloud. IaaS helps companies build the infrastructure of cloud-based services, including software, content or e-commerce websites to sell physical products. Companies that use SaaS don't have to manage their data use or maintain their applications. With PaaS and IaaS, however, users must manage their own data use and applications. SaaS and PaaS providers manage organizations' operating systems, but IaaS users must handle their own operating systems. SaaS Pros, Cons and Use CasesPros of using SaaS include:

How to Choose Between SaaS vs. PaaS vs. IaaSThe size of your organization can help determine which cloud model to use. A few recommendations include: Small/medium/large companies with limited resources: SaaS Businesses can save money with software as a service because they don't have to design and develop the software themselves. It makes sense for companies to use SaaS products that meet their business requirements because they can quickly be more productive. Medium/large organizations with some resources: PaaS Medium and large businesses with IT departments should consider platform as a service as an option, particularly if they need customized applications that can more easily integrate with their workflows and technologies. Medium/large enterprises with moderate resources: IaaS Medium and large businesses that have the necessary IT resources should think about using infrastructure as a service. The almost complete control that IaaS provides means they can create highly customized technology stacks that meet an organization's specific business requirements. IaaS also makes it easy to adapt the technology if business requirements change. Although similar, choosing among software as a service, platform as a service and infrastructure as a service means companies have to find the right balance between giving up control and saving their employees time and effort so they can be more productive.
