Archive for Virtual Private Server (VPS)
Virtual Private Server (VPS) is a virtual environment hosted on a node server with several other Virtual Private Server (VPS). By having a Virtual Private Server (VPS) you have your own server, more or less, and you can add programs and features as you like within your own environment without being at the mercy of other users. This can prove to be an advantage for some resellers since they might require special security settings which they’d never be able to get set on a reseller account.
A Virtual Private Server (VPS) is perfect for you, if you require a dedicated environment but are not able to afford a dedicated server or if you have outgrown your standard reseller account and have no choice but to upgrade to a dedicated environment. If you are using a control panel such as cPanel then you should be able to get all your data and websites moved over without causing any downtime or hassle to your customers.
Upgrading to a VPS From Shared Hosting Environment
Shared Hosting
Shared hosting is an environment where several websites are all hosted on one web server. Each website account gets its own limited share of disk-space, bandwidth, email accounts, FTP accounts, databases. No server administration, security administration & other system tasks to be performed. Its plug-and-play means you just buy an account & start using it. This only caters to small websites or individual users.
VPS Hosting
Virtual Private Server (VPS) Hosting is the technology that separates one physical server into several independent virtual servers parts, each isolated from the other. Each Virtual Private Server (VPS) has its own set of processes and resource management, and behaves exactly like a stand-alone server. It allows you a larger amount of resources available for use. You also get full administrator level root access for your Linux / Windows Virtual Private Server (VPS) respectively.
With the Virtual Private Server (VPS) Hosting, you are under the control of all operations & processes running on your server.
It is a perfect balance of a shared environment and a completely independent hosting environment.
Do not cancel your existing account till the time all the websites start resolving from the VPS.
Your data would be there for you, unless you asked not to move the files. Once you have verified that everything is correct, then you start off using your Virtual Private Server (VPS).
You should ensure that you have the nameservers in place. Depending on your Virtual Private Server (VPS) plan, you are allotted a specific number of dedicated IP. You would have to change the nameservers for your domain name in your registrar account. Once all the websites have the correct nameservers, you just have to go on adding more websites, everything would be done.
The step-up is suitable, when you have to take care of the administration tasks, which include System processes (management), repairing the Virtual Private Server (VPS), backing up data & storing it, Virtual Private Server (VPS) re-installation, reboot & overall management. Basic knowledge of the Linux / Windows would also be a plus point. You may also install any application or software which is compatible with Virtual Private Server (VPS).
There is also a difference between Guaranteed RAM & Burstable RAM.
Guaranteed RAM is what you will always have available for use on your Virtual Private Server (VPS). However, you might have occasions where your Virtual Private Server (VPS) would require more than the available quota of RAM for the system processes & other applications to be functioning.
Burstable RAM is available on the server node to be used whenever there is a short time requirement. However, this is subject to the usage of other Virtual Private Server (VPS) hosted on the node. Abundant amount of resources are almost always available on each server node. But burstable RAM is not something which would always be available. If your Virtual Private Server (VPS) happens to use up the additional RAM available on the main node, it would start hampering the performance of other Virtual Private Server (VPS) too, hosted on the same server.
