Web hosting service plays a vital role in the modern computer era, as there are billions of websites available in the World Wide Web via this service. The hosting place where the data of the particular website are stored can be anywhere in the world. Making the website available 24*7 with no interruption is the ultimate target of any web hosting service. Also supporting the updates of any programming language in which it has been built is very vital, as the competition in the web hosting service is very high. Email hosting can be either integrated along with this service or can be subscribed as a separate service. Depending on the requirement from the owner of the website, limit can be imposed on the mail storage of the users, as well as the maximum number of people that can be allowed at any particular time.
Backup servers can also be purchased if the visitors limit is crossed. It’s a good practice to buy the servers at different locations as it will not impact the users in case of severe natural calamity in the web hosting locations where the users data is stored.
The scope of the web hosting varies from a small site with few pages to a social site network such as Facebook/Twitter where billions of users get connected with no interruption. The downtime of a website can be calculated easily as the historical data can be accessed at any time from the service providers. Downtime for maintenance on the servers/systems can be scheduled earlier as per the Service Level Agreement (SLA) between the service provider and the customer. This will help to intimate the user at the earliest.
There are some free web hosting services available as well, it may be quite interesting to understand how they make profit by providing the hosting service at free of cost. Web ads help them to make it possible but the limitation will be more for the users when compared to the users subscribing the paid web hosting service. For making the web hosting service economical to the users, web hosting servers can be built with common RAM and CPU, these are formally known as shared web hosting service.
The Big Organizations will always go for a dedicated web hosting service where they have the complete control over the servers which indeed have their all business related data. The most recent form of this web hosting service is the cloud hosting where the users are charged only for the amount of data accessed by them, also more immune to the natural disasters as it is not located at any particular centre. Any single RAM/CPU failures don’t affect the users subscribing the cloud hosting service. To make it clear any type of web hosting service can be chosen depending upon the intent of the website.
