What is Virtual Private Server ?

Virtual Private Server (VPS) is a virtual machine sold as a service by an Internet hosting service. A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS.

What does A VPS stand for ?

VPS stands for Virtual Private Server. VPS hosting is a source of confusion for many individuals and businesses searching for a web host for their Internet ventures. The reason for this is that it really is a hybrid of shared hosting and dedicated hosting.

How a VPS works
A VPS hosting provider relies on virtualization software, called a hyper-visor, to abstract resources on a physical server and provide customers with access to an emulated server, called a virtual machine (VM). Each virtual machine runs a complete operating system, and has restricted access to a portion of the physical server’s compute, memory and storage resources. Customers have access to the VM’s OS, but not to the physical server.

While multiple tenants can share VMs that reside on the same physical server, those VMs are restricted from interacting with VMs owned by other tenants, hence creating a server that is logically private, but not physically separate.

Advantages of VPS hosting
One of the primary advantages to using a VPS, as opposed to a traditional web hosting service, is that the subscriber has full access to the VPS’s OS, with unrestricted root or administrator permissions. This level of access allows subscribers to configure the VPS to meet their own unique requirements.

When is the right time to switch?

Is VPS the right answer for your site?

Most hosting users are on VPS hosting for more server resources (shared hosting offers limited CPU resources) and better control over the hosting environment (safety). Also, some users who are wary of the technological know-how simply take VPS hosting as the stepping stone to dedicated hosting.

If you are on shared hosting, when is the right time to switch?

Most websites launch using a shared hosting plan. And that’s absolutely okay because shared hosting is the easiest option for starters – it’s cheap, easy to manage, and requires very little technical knowledge. However, as your site grows and demands more functions, VPS hosting becomes a necessity at some point.

In case you were confused, here are a few indications that (maybe) it’s time to switch over to VPS.

1. Heavy Traffics

You have a high amount of incoming traffic. Sometimes you will receive a notification from your shared hosting provider if you are pulling too many resources from the shared server – this is a tangible way to know that you need to upgrade your server capacity. If you don’t receive a notification from your provider, watch your load times and visitor traffic – your growth is an excellent indication.

2. Reliability and security

You need a stable stream of resources for better website reliability. Or, you need to implement better backups, advanced monitoring capabilities, and enhanced security features (such as SSH – or secure shell access)

3. Better control / Server root access 

You have reached a point that you require complete control over your web host to perform more advanced actions, such as installing custom software or a custom server configuration.

Or, you need better control over your users. For example, if you are a developer who helps clients to design and host their own websites, you likely take on some of that hosting work and responsibility – VPS hosting will give you better control over user access, while also allowing you to give your clients access to the servers.
