Do you feel like you have outgrown your current web hosting? Do you require more power and better performance to handle the massive traffic than you are currently receiving on your website? Are you on a budget and you want to scale your hosting solution without breaking the bank on an expensive dedicated server? If this sounds like you, then you most definitely need to invest in a Virtual Private Server or a VPS in short.

What is a VPS?

Let’s first begin by looking at the extremes of web hosting. Lets’ begin with shared hosting. In shared hosting you have one server shared across multiple customers. These customers share the server’s resources such as CPU, RAM and Disk Space. It’s easy on the pocket and effective. However, Shared hosting does not give users total control over their server’s resources and security. If one of the virtual servers is breached, then other clients’ servers on the shared server are equally at risk. In addition, it’s a challenge when scaling up your server in the event of future growth of the business.

On the other end, we have Dedicated hosting, a sharp contrast from shared hosting. In dedicated hosting, the server is specifically reserved for one customer and the customer gets to enjoy the entire server without sharing with anyone else. There’s a  high degree of customization than shared hosting. In addition, clients have full control of the server including the choice of the Operating System – whether Windows or Linux. Dedicated hosting comes packed with huge benefits such as high performance, enhanced stability, and better control. On the flipside, this type of hosting is costly, and for this reason, it is usually used by high-traffic volume websites.

Over the years, a hybrid model has emerged, leveraging the benefits of dedicated hosting and shared hosting.  This approach is known as Virtual Private Hosting. Virtual Private Hosting is a website hosting model where a physical dedicated server is split into multiple virtual machines, commonly known as Virtual Private Servers (VPS). This is made possible through virtualization technology where a hypervisor allocates hardware resources such as RAM, CPU and disk space to virtual instances. Each VPS is independent of each other such that they can run different Operating Systems and varied set of applications. This approach has significantly made it more cost effective for businesses and website owners. More importantly, the model allows clients to start small and scale up as the business gradually grows. Generally, VPS hosting is chosen by website owners with medium level traffic that surpasses shared hosting plans but at the same time do not require resources of a dedicated server which will be costly.

Virtual Private Servers come in two main configurations: Single Server VPS and Cloud VPS.

Single VPS and Cloud VPS

In a single Server VPS, several virtual servers are hosted on only 1 physical server. In a Cloud VPS, virtual servers are hosted across several physical servers, usually located across different geographical regions making up what is known as the cloud. The Single server VPS is low cost because only 1 server is required to host several VPS. The downside of this is limited scalability because of the hardware constraints of the single server. At the same time, this kind of model does not allow for high availability and fault tolerance. For cloud VPS, several dedicated servers are pooled together forming what we call a hardware cloud. The beauty with this model is that in the unlikely event that something goes wrong with one server, the VPS will continue working because data is still stored across other servers as well.  At the same time, there’s high availability and you can easily scale your requirements as your business grows.

So, what are the advantages of a VPS over dedicated hosting?

A VPS is cheaper unlike dedicated hosting and cost-effective as you use what you need without incurring overhead costs. A VPS is also easy to deploy – take a few minutes -, provides high availability, fault tolerance, and scalability. You can easily upgrade and downgrade according to your needs.

“When do I need to deploy a VPS?” you may be wondering. If you need control over your own Operating System, If you need more power for your website, if you need to make your own customizations and have total control of security in your hosting environment, and lastly, if you need dedicated resources such as disk space, CPU and RAM,  then a VPS is definitely the right option for you!

In conclusion, VPS hosting is ideal for those seeking growth and total control over their system. Virtual Private servers are easily scalable and provide the user with total control over the server’s resources and security as well. It’s most suitable for small to middle-level business with growth and expansion in mind which is made seamless by the VPS hosting provider.
