Cloud Service Provider (CSP)
Cloud Services Providers offer and manage SaaS (Software as a Service), PaaS (platform as a service) or IaaS (infrastructure as a service) for their end-customers.
Examples are Interxion and SaaSplaza
MSP versus CSP
MSPs are a superset of CSPs. Generally speaking, MSPs manage both on-premise and cloud-based workloads and infrastructure for end-customers. But the MSPs may not actually own or control the underlying cloud infrastructure. In contrast, Cloud Service Providers typically offer and manage SaaS (Software as a Service), PaaS (platform as a service) or IaaS (infrastructure as a service) for their end-customers. MSPs may also manage those services without directly hosting the offerings on their own.
On a slightly related note, Microsoft considers Value added resellers (VAR’s) and MSP’s that resell Office 365 to be Cloud Solutions Providers — rather than services providers.
Value added reseller (VAR)
A value-added reseller (VAR) is an organization that buys equipment from a vendor at a discount, adds value (such as application software packaged and sold with underlying system software) and re-markets it.
Examples are Delaware and Prodware
Systems Integrator (SI)
An enterprise that specializes in implementing, planning, coordinating, scheduling, testing, improving and sometimes maintaining a computing operation. SI’s try to bring order to disparate suppliers.
Examples are Dimension Data and CGI
The IT consulting industry can be viewed as a four-tier system:
- Professional services firms which maintain large professional work forces and command high bill rates.
- Staffing firms, which place technologists with businesses on a temporary basis, typically in response to employee absences, temporary skill shortages and technical projects.
- Independent consultants, who are self-employed or who function as employees of staffing firms, or as independent contractors in their own right.
- Information Technology security consultants
Examples are Atos and Accenture

A distributor is an entity that buys noncompeting products or product lines, warehouses them, and resells them to retailers or direct to the end users or customers. Most distributors provide strong manpower and cash support to the supplier or manufacturer’s promotional efforts. They usually also provide a range of services (such as product information, estimates, technical support, after-sales services, credit) to their customers.
Examples are Arrow ECS, Also and Copaco
Independent Software Vendor (ISV)
A software producer that is not owned or controlled by a hardware manufacturer; a company whose primary function is to distribute software. Hardware manufacturers that distribute software (such as IBM and Unisys) are not ISVs, nor are users (such as banks) that may also sell software products.
Examples are Microsoft and Exact
A service in which a vendor offers the housing of business-to-business (B2B) or business-to-consumer (B2C) e-commerce websites via vendor-owned shared or dedicated servers and applications for enterprises at the provider-controlled facilities. The vendor is responsible for all day-to-day operations and maintenance of the website. The customer is responsible for the content.
