In Cloud Computing, there are three types of common cloud services and four types of common cloud deployments. This week, we will talk about the three types of services. They are software, platform, and infrastructure services.
Software as a Service (SaaS) allows businesses and consumers to use applications that are hosted by a cloud provider. When you use Netflix, Microsoft 365, Gmail, or Google docs, you are using SaaS. Check out http://www.ibm.com/developerworks/cloud/library/cl-cloudservices3saas/ to learn more.
Platform as a Service (PaaS) is an application platform that allows developers to build and deploy applications without having to maintain an infrastructure. Check out http://www.ibm.com/developerworks/cloud/library/cl-cloudservices2paas/ for more information.
Infrastructure as a Service (IaaS) uses a cloud provider to provide datacenter hardware needed. The provider will host servers for a business. They are able to increase and decrease the size of the servers in a very short time period. Businesses just pay for what they use.
