Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is cloud service applying to Infrastructure level such as Server, Storage, Network, Security,… With IaaS, resources are always ready in Service Provider, you just need to choose accurately, which suitable with required configuration. You don’t have to buy device, system development and management personal cost. The Service Provider owns and manages these infrastructures in accordance with the SLA. Access to resources is accomplished through IP Public or VPN. In particular, most IaaS services provide a self-service portal that allows customers to interact directly with monitoring, administration, optimization, etc. IaaS is sometimes referred to as Hardware as a Service (Haas).
Platform as a Service (PaaS)
PaaS is a service model based on IaaS (Server, Storage, Network, Security, …) with the addition of OS components and middleware to create a computing environment that makes it easy to develop and deploy applications. With PaaS, software developers or IT departments of the enterprise can quickly set up the application programming environment. This allows us to focus on refining the functionality of the application rather than the complex infrastructure underlying it. Some famous PaaS platforms include Google App Engine, Microsoft Azure, Salesforce Force.com.
Software-as-a-Service (SaaS)
SaaS is software services deployed on Service Provider systems that can be accessed and used anytime by a Web browser. With SaaS, you do not have to worry about deploying the software, just choose the software that suits your needs. SaaS services charge subscription fees, so you only pay a monthly fee for the number of accounts you use.
