Introduction •
Cloud computing has three most common types of cloud services to offer. Depending on the needs of users, any type of cloud computing service is used either individually or in combination with others. The following is a brief introduction to the three cloud service types, namely, SaaS, PaaS and IaaS.
Different types of ClouD Computing Infrastructure as a Service Platform as a Service Software as a Service Recovery as a Service Hybrid cloud Community cloud
Infrastructure as a Service •
IaaS is the lowest level of cloud solution and refers to cloud-based computing infrastructure as a fullyoutsourced service. An IaaS provider will deliver pre-installed and configured hardware or software through a virtualized interface. What the customers accessing the cloud services do with the service is up to them. Examples of IaaS offerings are managed hosting and development environments.
Platform as a Service •
This type of cloud computing is similar to IaaS but is more advanced. With PaaS, apart from simply providing infrastructure, providers also offer a computing platform and solution stack as a service.The IT infrastructure may come with a graphic user interface, run-time system libraries, programming languages or an operating system.
Software as a Service •
When talking about cloud services, most people think of Software as a Service (SaaS) providers. SaaS providers provide fully functionally webbased applications on demand to customers. The applications are mainly targeted at business users and can include web conferencing, ERP, CRM, email, time management, project tracking among others.

Recovery as a Service (RaaS) solutions helps companies to replace their backup, archiving, disaster recovery and business continuity solutions in a single, integrated platform. RaaS providers protect and can help companies recover entire data centers, servers, and data.
Hybrid Cloud •
Hybrid clouds cannot be just categorized into public, private or hybrid cloud because they can overcome the provider’s boundaries. Here, resources are provided by either external or internal providers. This is usually an adaptation among two platforms, where the exchanges are done between public and private cloud based on demand and pay-perthe-need.
Community Cloud •
In community cloud, cloud resources are mutually shared between many organizations which belong to a particular community, for example, banks and trading firms. This setup is typically shared amongst several organizations belonging to a certain group, which has the same computing apprehensions.
