Software as a Service (SaaS) is the most commonly used area of cloud computing that provides multiple cloud tenants access to a certain application.
Office 365 is a form of SaaS where anyone can open a monthly subscription to Microsoft’s suite of Office products. SaaS provides a complete solution owned and managed by an IT services provider. These solutions are optimal for end-user applications for daily operations.
Infrastructure as a service (IaaS) includes the basic necessities for the cloud and offers access to network functions, virtual machines, dedicated hardware and storage space. These technologies serve as the foundation for your business operations, SaaS and other cloud-based services.
Windows Azure and Amazon Web Services are two common IaaS providers that enable you to outsource infrastructure like backup and storage space, space needed for testing and more. Azure offers access to virtual networks, service buses, message queues and non-relational storage platforms.
When considering which cloud computing solution is right for your business, you need to think in terms of hosted, hybrid or on-premises solutions. IaaS, SaaS and PaaS include the equipment software and applications that operate on the cloud. Hosted, hybrid and on-premises are the common deployment models of cloud computing. Let’s dive into these options a bit more.
A hosted cloud is a complete cloud deployment with all the applications and services you need. In a hosted cloud, applications are already available, and new applications can be developed on low- or high-level infrastructure. Hosted cloud solutions are entirely managed, owned and maintained by a managed services provider and require monthly subscription fees.
