A web hosting service is a type of service which allows an individual or organisation to make their website available via World Wide Web. These websites are hosted on special computers called servers. Two prominent types of web hosting are Shared web hosting and VPS hosting.
Shared web hosting and VPS hosting are two related terms but also quite different as far as applicability is concerned. In shared hosting you get a space on the server but the space is shared with other web sites. In a way you are sharing resources like bandwidth and memory on the server. VPS hosting a different concept altogether. A space is given on the server which looks like a dedicated space where you share the resources of the server all to yourself but within a shared hosting environment.
Shared hosting is like renting a room in an already shared house. A small room is given to you but you are a part of the total space occupied by other people. VPS hosting is like an apartment in a block given to you. You have got big rooms, your personal space altogether with world of privacy but still you are the part of a sharing of the whole block.
A question arises whether one should choose VPS hosting or Shared Web hosting. If the web site is having a static content it is always better to use shared web hosting. It is good for personal sites like blogs. You don’t get features like security and fast loading speeds but actually those are not required for such websites. If you want to have a website for small businesses, departmental stores etc. you need to have VPS Hosting. Those websites support dynamic content and are able to host a large number of people. If the plan of a business enterprise is to grow then it is always better to have VPS hosting. In other words if your website is a low traffic one then it is always better that you go in for shared hosting.
Resource allocation is one of the major points in reference to comparison between Shared Web Hosting and VPS hosting. In Shared web hosting if one website is using too much bandwidth then other websites might suffer due to it. It is just like wanting to cook in your kitchen when all gas burners are already working and occupied. In VPS hosting because you own a large portion of the server you have more resources at your disposal.
Definitely, VPS hosting is safer as far as security is concerned. Your site is on VPS hosting server and similarly other sites are on VPS hosting. All have their own security. You can install CCTV and alarms in your own flat. You are secured even if someone leaves the front door of your block open. Shared server hosting is like you are having keys of your bedroom but your housemate leaves the front door of your house open. You are still at risk. If security breach occurs on one site of a server the other sites on that server at equally at risk.
You might be having all resource on your website but what the users or the visitors want is that your website should open in 1-2 seconds. No one has the patience to wait for a website to open in more than that time. On those counts also VPS hosting is always better. Since a large number of visitors might visit your website in the near future it is always better that the site opens in a couple of seconds.
Scalability factor is another feature to look out for while deciding whether you want to go in for Shared web hosting or VPS hosting. You need to consider how many visitors you want to accommodate in the future. If you think that your business is ought to grow in the near future and you would need to accommodate a large number of visitors on your website it is always better to go in of VPS hosting. If you think that your website will need let us say about 25000 visitors per month then it is always fair if you go in for shared hosting. If however, your website needs to accommodate visitors much higher than that in the case of shared hosting you will start receiving internal errors from your host.
As far as costing goes definitely VPS hosting is a much costlier option. Moreover, costs vary as per plans selected by you. The higher the plan the more the prices. But VPS hosting gets in more resources at your disposal. You can choose higher plans if your business demands it. It all depends how much traffic you need for your website currently or in the near future.
