With the increasing trend for companies to outsource (such as certain accounting or IT functions), cloud computing has increasingly become a solution for organizations. It’s an innovative and increasingly popular model of software deployment that offers enterprise-class software function without traditional up-front infrastructure costs or the unpredictable support and maintenance costs of on-site software and hardware.
From infrastructure to security to personal productivity to workflow, CRM, accounting and ERP, there are today mature, cloud-based applications available in nearly every segment of the software marketplace. The typical types of cloud computing methods include:
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
- Infrastructure as a Service (IaaS)
