The ability to scale : Because the cloud service provider supplies all necessary infrastructure and software, there's no need for a company to invest in its own resources or allocate extra IT staff to manage the service. This, in turn, makes it easy for the business to scale the solution as user needs change—whether that means increasing the number of licenses to accommodate a growing workforce or expanding and enhancing the applications themselves.
Lowered costs : Many cloud services are provided on a monthly or annual subscription basis, eliminating the need to pay for on-premises software licenses. This allows organizations to access software, storage and other services without having to invest in the underlying infrastructure or handle maintenance and upgrades.
Software as a Service (SaaS) : The most widely recognized type of cloud service is known as software as a service, or SaaS. This broad category encompasses a variety of services, such as file storage and backup, web-based email and project management tools. Examples of SaaS cloud service providers include Dropbox, G Suite, Microsoft Office 365, Slack and Citrix Content Collaboration. In each of these applications, users can access, share, store and secure information in “the cloud.”
Infrastructure as a Service (IaaS) : Infrastructure as a service, or IaaS, provides the infrastructure that many cloud service providers need to manage SaaS tools—but don’t want to maintain themselves. It serves as the complete data center framework, eliminating the need for resource-intensive, on-site installations.
