If you are a small business or individual entrepreneur looking to set up a web presence, there are many more options available to you for web hosting and development than ever before. The market has changed so much in the past few years it is virtually a whole new world from what was available in the early two thousands. Cloud hosting has taken the computing world by storm and the options around hosting a web site are often more flexible but can be more confusing than ever before.
Shared hosting environments are what enable the new crop of cloud computing environments. Large server farms such as Linux Enterprise Red Hat and Windows Azure Server are the operating system environments for large cloud datacenters that host hundreds of virtual servers on only a couple of large enterprise class servers. The technology that allows one or two large servers to host dozens or even hundreds of virtual server environments is called hypervisor. The hypervisor works as a management layer between the “bare metal” of the server hardware and the multiple virtual machines running on the box. Each virtual machine server in a shared hosting environment is isolated from each other virtual server and given its own dedicated resource pool. Typically each virtual machine will be guaranteed a minimum allocation of hardware resources as needed and can be set up to max out at a certain amount or resource usage. Since not all virtual servers will need all of the resources such as RAM or CPU at the same time, the hosting provider can purchase a single large server that actually has much less physical capacity than is doled out to each virtual server. This is kind of like time sharing.
There are a couple of practical upshots to this shared hosting server environment. First of all, you do not have to purchase hardware in large chunks such as you would with dedicated server hosting. With dedicated server hosting, you would actually need to figure out if you need to rent 8, 16 or 24 processors and how much RAM you need to dedicate to your site to accommodate the load you estimate for the year. With shared hosting, however, many hosting providers will allow you to work in a pay as you go method. This method of working is great for businesses who have a hard time estimating how much traffic or resources they need for the year, such as small businesses that are just starting to take off. This is also great for businesses that are seasonal in nature because they can utilize heavy resources during the busy season, Christmas time for instance, and utilize a smaller load the rest of the year and only pay for the resources that they actually use from month to month. The efficiency in hardware resources that the hosting provider saves by purchasing less hardware will ultimately save you money by offering much more computing resources for a smaller price.
For as many benefits as shared hosting provides, there are still a few instances where dedicated hosting is the best or even only option available to you. Many banks or financial services institutions have certain state regulations around them concerning the handling of their customer’s financial data. Some banks, for instance, are regulated to keep their customer data within a certain range of their geographic bank location. Some health care providers have similar regulations around the handling of private health information. In these cases, the use of a shared environment is not really an option and dedicated hosting is the only way to go.
