In some instances, the performance of a VPS is limited to the hardware and software specifications of the host machine. You have a finite amount of CPU and memory resources at your disposal, and you are not free to change the operating system’s global configurations. Nevertheless, there are a plethora of OS and software parameters […]

In-box upgrades on any operating system can be tricky. You are essentially updating all of the software, including the kernel, while keeping all of the current data. This makes it inherently risky, and some would argue against it and maintain that you should either not do upgrades or only do backups and clean installs.
For Ubuntu […]
It is generally understood that a server running Linux needs to have a relatively recent kernel version or at least one that has been securely patched to fix any vulnerabilities. For dedicated servers, a kernel upgrade is not big deal; a simple install, reboot and you are done. For a virtual private server, it can […]
Overselling is not a new concept. Every web hosting company that offers “unlimited” anything (bandwidth, disk space, etc.) is overselling. There is always a limit, even if they do not tell their customers. Their bet is that at least some customers, maybe even most, will not use up all the resources at once. It […]
The “Information Age” has left us with more information than we can easily handle. As a result, storage has become an industry in itself, and it is no longer just for backup and recovery. Simple access and retrieval can be difficult when you have terabytes of data to deal with. Virtualization has presented its own […]
One of the frequently mentioned benefits of VPS hosting is that it is more secure than shared hosting because your account is walled off from other accounts, allowing them to function as separate servers. Virtual private servers and virtualization in general are generally thought to be secure. So, can one virtual machine compromise the security […]
Virtualization has been one of the best technologies to develop in a long time for many organizations. Server deployment times are shorter, data centers are more energy efficient, and overall operational costs are down. In short virtualization is almost certainly something you should consider for your servers. What follows are some tips that should […]
OpenVZ is free and open source virtualization software that gives you the ability to create and manage virtual private server containers on your dedicated server. While you could manage it quite effectively from the command line, you may prefer to use some type of hosting automation system. The following are some free web-based management tools […]
Virtualization is extremely popular in the server world right now, and many organizations swear by it. Still, there are some IT people that will look at individual virtualization examples and say to you, “Why don’t you just use a chroot environment.” There are pros and cons to this method, and we will discuss the benefits […]
KVM is a Linux-based virtualization system that allows you to virtualize a wide variety of operating systems and environments. When you want to manage your virtual machines or guests, you can use a program called virsh. As a command line tool, you can use virsh to manage guests and the hypervisor. It is built on […]
Virtualization can save your organization a lot of money, so it is no surprise that it has become a popular tool for server deployment. What once required 4 dedicated servers may now only need one server running four virtual machines. While enterprise-level virtualization is inexpensive compared to actual hardware, it is still not free. To […]
In an earlier post, we learned how to setup a new virtual machine in VMware Player for the purposes of testing a server implementation. In this post, we will look at some ways you can manipulate VMware Player to emulate your server environment.
One of the first things you will want to do is […]
In the past, creating a testbed environment for your server often involved setting aside an old machine or even using a desktop or laptop computer. In most cases, it was difficult to mimic the exact hardware configuration of your server and not as efficient. Virtualization changed all of that, and VMware Player is one free […]
When businesses talk about virtualization, they are often concerned with the financial savings that it can bring. When IT people talk about it, they usually laud its ability to do more with less space, fewer servers, and often less effort. In addition to those technical and financial savings, virtualization can also help conserve energy in […]
Most web hosting companies offer some form of VPS service, so it can be difficult to decide which one is right for you. A virtual private server can be almost anything that uses virtualization, so it is important to know what you are getting and if the services offered fit your needs. These are some […]
A virtual private server (VPS) is a low-cost alternative to a full dedicated server. Using a VPS has a number of strategic advantages for small and medium sized businesses. Among those advantages are the following:
Savings – Above all else, a business that is small or just getting started will need to find ways to […]
In a previous post, we looked at some of the ways that virtualization can help you save money. It can help you maximize space usage, reduce power consumption, and reduce the amount of time you spend on provisioning and deployment. The following are three more ways virtualization help:
Application consolidation – In the […]
There are many ways to create virtual machines and many virtualization tools you can use. KVM is one tool that is built into most Linux distributions. Cloudmin, an optional add-on for Virtualmin and Webmin, can provide a graphical interface for creating and managing virtual machines.
To create a virtual machine in Cloudmin, do the following:
1. Click […]
Sometimes you need a dedicated server but do not need the full hardware package. A VPS is great for small server projects that do not require the full power and memory available on the system. Moreover, many cloud companies offer VPS systems that are quick and easily to deploy, charging monthly or even hourly fees […]
Saving money is very important in the competitive dedicated server industry, and a good system administrator will always look for ways to help the business save. Virtualization, when used correctly, is a great way to save money and still get good performance out of a server. The following are three ways to save with virtualization.
One of the dangers of hosting virtual private servers is what is known as virtual server sprawl. Like constructing buildings in an area, only so many virtual machines can occupy a single server. High demand for VPS accounts may quickly out pace your ability to create new machines or even deploy new servers to host […]
When shopping for a virtual private server (VPS), one of the terms you will come across while reading technical specifications is “burstable RAM”. Usually, the specifications will list the amount of RAM available on a VPS package and then list the burstable RAM, which is always more than the allocated RAM amount, beside it.
As the […]
Virtualization gained many fans in 2011. More system administrators than ever before are seeing the benefit of creating virtual machines for a variety of purposes, from sectioning off business operations to hosting virtual private servers for customers. The more virtual machines you have, the more difficult it can be to manage all of them. Fortunately, […]
Virtualization can save you time and money when used efficiently. This has made it very popular for small, medium, and large sized data center operations. Whether you have a single server or a fleet of them, virtualization has its benefits.
KVM and Xen are two virtualization options for Linux servers, both with their advantages. Xen is […]
Depending on the business you are involved in, opting for a dedicated server may make the most sense. On the other hand, there are plenty of situations where you can make a strong case for a virtual private server (VPS) to save money and make things a little easier for you.
The following are benefits of […]
Once you’ve purchased a VPS to store your data, run your apps, or act as a testing environment, the next step is customizing your server environment so that it works best for you. This can take the form of optimizing your Linux or Windows OS, and then using the VPS control panel you have available […]
Running a LAMP VPS means choosing a distro to go along with your server space; a choice that often comes with a number of judgments on the part of so-called “experts” in the field. Everyone has their favorite distro for their own reasons, but each one performs admirably in its own space. Choosing one comes […]
A VPS (virtual private server) gives you the ability to host several instances of your operating system within a single dedicated server. Each virtual machine or container within your server behaves independently as though it were a server by itself. This gives users all of the benefits and administrative access of a full dedicated server […]
Yesterday, we looked at low end boxes, inexpensive servers with less powerful hardware than your average high-quality dedicated server. Many low end boxes are actually virtual private servers (VPS), and are, therefore, technically not boxes at all. With a VPS, you share your server with other tenants, all of whom need to play fairly to […]
Every system administrator should have a server backup of some form. For on-premise servers, it may be an external storage device, either physically connected to the server or stored within a network-attached storage (NAS) device. For remote servers, you can still use a local storage or lease a separate server for backups.
In some cases, your […]
