Web hosting is really just about having an online computer that serves a website.
In that case, you might be asking yourself: , then why do I need a hosting service? Can’t I just have my home computer host my website?"

Yes, it is technically possible but that would be a really bad idea unless the user has a large amount of resources and time at his disposal.  There are many reasons why web hosting companies exist and the low-cost and high performance of these make it affordable for everyone, not to mention tension free usage of the service.

Below are some of the shortcomings of having a hosting setup at home:

Self Hosting Pitfalls:

1)Power Outages - If your power goes out at the work station, the website will go down, resulting in a lot of complications. It is important to have a non interrupted power supply
2)Slow Connection - While the user may have very high speed Internet at home, this is usually in relation to to download speed.  However with a server, since the user is  sending files,he need a high upload speed. It is almost guaranteed that in most of the home internet connections, the upload speed is very low.
3)Dynamic IP Address - The home Internet connection has a dynamic IP address that keeps changing over time. This is like the house address constantly changing and people trying to send you mail. It makes it nearly impossible.
4)Hardware Maintenance - If the user's home computer has any issues or needs a new part, it could be days or weeks before the computer gets back to running  again, and all of that time the website will be down and you may even lose your files or business.

Web Hosting Companies to the Rescue:

1)Redundant Power Supplies - The power supplies at most web hosts are almost always backed up by on-site power generators that keep websites running even under extreme power outages.
2)Ultra-Fast, Stable Connections - Web hosting companies have their datacenters optimized for extremely fast upload speeds and can serve tens of thousands of concurrent visitors easily.
3)Static IP Address - With a web hosting company you can have a dedicated IP that will never change un like the home internet service. This means the address always stays the same and people can always find your site.
4)Expert Team Maintaining Hardware - The qualified experts at these web hosting datacenters constantly maintain the hardware and always have replacement parts on hand. They also have redundant hardware and backup your files for you incase of issues.As a result they are better able to manage your data and files.

Besides these reasons, web hosting companies such as www.vpb.com always have attractive offers and tariff plans for their hosting which actually make it cheaper and cost effective besides a 24/7 customer and tech support team which is on standby to solve any issues that may arise.Ultimately, it makes more sense to host the website and data using a professional web hosting company that can serve the client's needs.
