If you are migrating from enterprise to a cloud based solution, it is necessary to understand the different roles in cloud computing. In this post, I will cover the 6 major roles in the cloud setup.

Cloud Service Provider

This is the entity that provides the cloud service. The cloud service provider owns and controls the cloud computing platform. The services include SaaS (Software as a Service), PaaS (Platform as a Service), IaaS (Infrastructure as a Service) and IpaaS (Integration Platform as a Service). Based on the services provided, the CSPs can be broadly categorized into 3 types:…

  • Application provider – These are providers that directly provide you access to an application without you having to worry about the layers underneath.

Examples include Dropbox, Salesforce.com, Google Apps and Microsoft Office 365.
