If you are concerned about the practical examples of cloud hosting, you can notice these both under Infrastructure as a Service (IaaS) as well as Platform as a Service (PaaS).
Under IaaS, you are provided with a virtualized hardware resource, which you can use for installing a software environment of your choice, before you build a web application. On the contrary, when you opt for PaaS, you are provided with the same software environment, as a solution stack. This can be a database support, a web server software, an operating system or a programming support. With the help of this software environment, you can directly install and develop a web application. If your business has multiple complex IT infrastructures and you have a group of experienced IT professionals, you may consider opting for an IaaS model that can be customized based on your own requirements. If you don’t need to tackle an extremely complicated business process, you can also opt for a PaaS, and enjoy the ease of operation.
As an enterprise customer, you can consider opting for a Virtual Data Center or VDC, which is a developed version of cloud hosting. This employs a virtualized network of servers in the cloud. This can be used to host the entire IT operations of a business, including the websites.
Public cloud model is another example of cloud hosting that is quite relevant for business owners. This refers to the process of hosting websites on virtual servers that draw resources from a common source. This source is also used for other virtual servers that are publicly available. There are certain security measures in public clouds. This ensures the data is absolutely secure and kept private. It also ensures that the data will be sufficient for most of the website installations.
