What Are Web Hosting and How Do They Work?

The best free and paid website hosting companies briefly reviewed and compared to enable you make an appropriate decision on the one that best meets your requirements.


What are Website Hosting Services?

Website Hosting Services provide space on a web server owned by a company to host websites for their customers. These websites store files on the web server such as images, texts, plugins, codes, etc, and are available for viewing on the internet. Website Hosting Services facilitates creation, maintenance and optimal functioning of the website they are hosting. Website Hosting Services are provided by companies which are sometimes referred to as web hosts.


Types of web hosting

There are various types of web hosting, which provide services that meet the various needs of websites they host, namely;

1. Shared Web Hosting

This is when a website is being hosted on the same server and share the same server resources (CPU and RAM) and several other websites. The shared web hosting plan is relatively less expensive and can be set-up easily because all resources are shared, thereby making it a good option for beginners, or websites that are just starting up and are not expecting a high volume of traffic to their site in the short term such as blogs, personal websites and small to medium sized companies.

2. Dedicated Hosting

As your business grows and gradually becomes a large business with huge volumes of traffic to your website, you will require a dedicated hosting server in order to ensure your site performs well and is able to accommodate an appropriate number of resources.

With dedicated hosting, the server is rented exclusively by the owner of a website who will have the most control (known as complete root and admin access) over the server that stores or host their websites, including the type of operating system run by these server as well as the security of the server, which comes with a price.

In terms of cost when it comes to web hosting, the most expensive option is using dedicated servers. This type of web hosting are typically used by website owners who require total control of their server and websites with huge volume of traffic; dedicated servers require a high level of technical know-how for installing, configuring and continuous administration of the server. 

3. VPS Web Hosting

VPS (Virtual private servers) hosting can be considered as a stepping stone between shared web hosting and dedicated web hosting. With VPS hosting, customers are given full access for configuring the servers but they do not have the server dedicated to their needs. The server could be serving other multiple websites; however, the website owner of a VPS hosting plan has their own space on the server, maintains full control, and may not necessarily have the technical required knowledge.

Typically, VPS hosting is used by small websites and businesses that need the flexibility of owning a dedicated server, without having to pay so much for the hosting service. Also known as VDS (virtual dedicated server), website owners are provided with additional storage space, additional customization, and personalized installations of software and packages. However, VPS hosting are not suitable for handling huge volume of traffic.

4. Cloud hosting

The latest type of web hosting that has become very popular in recent years in the technology business is cloud hosting. It works across various web servers that are interconnected, thereby providing a cheap, reliable and scalable web infrastructure, which enables the utilization of several resources as required by users without needing to build and maintain their computing infrastructure. These resources are scattered across numerous servers, which reduces the possibility of the malfunction of a server and reducing downtime.

So many businesses are turning to the cloud because cloud hosting plans provides bandwidth that is reliable and unmetered, as well as offers an unlimited amount of disk space for limitless websites. It is effective in running websites with applications that are resource-intensive or a great amount of content properties such as images, and can be quite expensive. Your website can grow as time goes on, utilising as many resources as it needs and you only pay for what you use.

5. Reseller Hosting

This involves hosting a website or selling hosting services to third parties by an account owner who has a prearranged bandwidth and hard drive space. If you are looking for a hosting plan where you could share some of the resources allocated to you with another website owner or where you don’t necessarily need a certain amount of space you purchased, then you could consider reseller hosting.

With reseller hosting you could be paying wholesale rates to the providers; and can share your CPU, bandwidth, disk space, and even choose the price for your customers. You can even consider this as an extra source of income and could make substantial profits from this type of hosting plan. It is particularly suitable for anyone who is hosting multiple sites or entrepreneurs such as web designers, agencies, web developers and those interested in this type of business.


How to choose the Best Web Hosting option for your website needs

As your business moves online, you will need a high quality, reliable, cost-effective type of web hosting service that meet your website needs and in order to run your website successfully. However, this would be different for everyone in terms of the size of your business, the resources you have, the type of website you require, the volume of traffic you are expecting to your site in the short and long terms, and ultimately your budget.

This is considered as scalability; ensuring your web host offers scalable options with additional features if and when you need them.

It is important to have a web host that is always available to provide you with the required technical support when you need it. You do not want a situation whereby if your website goes offline, you may have to wait until the next day or couple of days to be able to get assistance in fixing it.

5. Bandwidth and traffic

This is the amount of data transferred from your server to browsers of visitors to your website. You the website owner would be using up bandwidth each time one of the pages on your website is loaded by site visitors using a mobile phone, tablet or computer, and you may be using significant amount of bandwidth if your site runs heavy contents such as videos, images or music. So, it is important to be aware that there is a limit on the amount of bandwidth you can actually use when you sign up to some hosting packages, and that if these limits are exceeded each month, you may be incurring additional charges.

6. Cost

Cost is an important factor to consider when choosing a web host. Compare the various pricing options offered by the web hosting providers and ensure thee are no hidden extra cost associated with the services you are signing up for, including as it relates to renewals, upgrades and bandwidth.

7. Storage

However be mindful that even though thee is a substantial amount of storage or unlimited amount of storage, you may not be allowed to store materials that are unrelated to your site. You may want to consider other storage options for these types of files/materials.

8. Location

The location of the data centres are important when choosing a web host. The location is also equally important if you collect any personal data on your website. You may be allowed by some web hosting services to choose the location of your data centre, which could greatly improve the performance and speed of your website.

Conclusion

From reading this article, you should now have a much clearer picture of what you need to look for when choosing a web host. You should understand that there are quite a few technical considerations you need to think about as well as looking at the service and support offered by the host.

One of the things you should do is look at the reviews that the web host is receiving to give you a clear indication of what the current customers of the web hosts think of their service. Nevertheless, after you have a tangible knowledge of the fundamentals of web hosting, you may want to reflect on the most appealing type of web hosting service that would meet your needs: shared, dedicated, VPS, cloud or otherwise.
