The Pros of Choosing VPS Hosting

The Pros of Choosing VPS Hosting

Friday, September 23rd, 2011

This article explains very common but necessary information and pros of using the Virtual Private Servers (VPS). A few crucial features are mentioned in this article, which are necessary to count when choosing a vps hosting provider.

VPS Hosting also known as virtual private server is a step up from the cpanel web hosting (ie. shared web hosting) solution. A physical dedicated server is divided into smaller servers using a server virtualization technology, such as Virtuozzo, providing each of them with isolated hardware and software features. A virtual server is private and dedicated, however it does share the actual physical server space with other vps accounts on the server.

Pros of Virtual Private Server (VPS) over Shared Web Hosting

A vps permits to have root access, Remote Desktop Access on a windows based server or SSH access on a Linux based server. The root access allows users to install their own favorite third party softwares, applications and scripts. A vps solution offers greater flexibility and complete control compared to a shared web hosting plan.

If you check out the resources, a vps will have defined limitations, but less restrictive than a shared hosting account. Usually, vps resources depend on the resources of the physical server it resides on. However, since each vps is isolated it will have a dedicated amount of resources at its disposal. These dedicated resources will not be affected by other vps accounts on the physical server.

Whereas, if you look at the shared hosting resources, they are unilaterally shared. Because of which, a sudden rise of traffic, or use of resource from one or two websites may affect the performance of other websites sharing the same web server. Since, vps is allocated with its own dedicated resources, such an issue won’t occur on it.

Also, due to the capability of performing exactly like a stand-alone server, each vps can be rebooted independently.

Additional Security

Unlike shared hosting, a vps is much more secure and doesn’t share the memory related resources with other virtual private servers on the same node. A vps has its own allocated dedicated resources such as RAM and Disk Space which are inaccessible by other virtual servers hosted on the same physical server.

The security advantage of featuring your own private Disk Space, RAM, and other resources is obvious. No one can maliciously interfere, other users cannot intrude, and you get complete control over any applications or softwares you install on the vps.

Unmanaged and Managed VPS

An unmanaged vps solution is simple as the unmanaged word defines. Users have complete control over all the aspects and are free to install and manage their own vps softwares and applications. For a technically expert user, an unmanaged vps hosting offers overall control. An unmanaged vps plan will always be cheaper than a managed one, as there are no extra administration charges to incorporate.

However, a managed vps hosting solution would be much easier for anyone that has limited technical skills or don’t have much technical knowledge. By choosing a managed vps, the web hosting provider will add a helping hand and manage few aspects of your vps hosting account, such as updates, upgrades and software installation.

VPS Issues Created By Poor Hosting

a] CPU Usage and Overselling

  • CPU resources of a VPS fully depends on the size of the CPU processor installed on the main node (ie. physical server it resides on) and the number of vps sharing the same CPU.
  • A low powered CPU may attempt to efficiently fulfill the demands placed on it by too many virtual servers, resulting in slower load speed and downtime for websites hosted on those virtual private servers.
  • When a web hosting provider oversells the server space, an issue like poor performance occurs. It is said “too many cooks spoil the broth” and that’s especially true with vps hosting. An excess of users on one vps can overload a CPU, resulting in poor performance.

You should look for a reputable and stable web host who can offer decent CPU resources and capably manage the vps.

b] Restrictive RAM Issues

Some cheap vps hosting providers offer low RAM allocation with their cheaper vps plans. It is necessary to check the amount of RAM (Memory) included in the plan the web hosting provider offers. Every website has a different requirement of RAM depending on various factors. If a website intends to run larger databases, or resources intensive applications or CMS platforms, then having a restriction on RAM will be an issue.

A cheap vps plan may only offer a 128 MB of dedicated RAM. Though it is fine for most of the basic HTML based websites, but way too limited for CMS based websites, and websites having multiple smaller databases and resource intensive applications. In some cases, a decent shared web hosting package may be superior to a low cost vps package with limited RAM. Never get influenced by cheap rates without checking the RAM allocation.

Signs of Quality VPS Hosting Provider

Flexibility

A decent vps hosting company should offer an option to configure the specifications, such as Disk Space, RAM, Bandwidth as per the requirements. The benefit of this over dedicated hosting is that the user will only be paying for the resources which are going to be used. Also, the web hosting provider should be able to increase the allocated resources if required.

Burstable RAM

A vps plan with burstable RAM covers up the flexibility aspect. The burstable RAM allows a user to exceed the allocated RAM limits when a website finds a sudden spike in traffic. However, the burstable RAM is not always guaranteed and available. It is simply a potential backup for your resource. If a website is perpetually surpassing its allocated amount of RAM, the user should upgrade the hosting package to add a larger amount of RAM.

Why Choose a VPS Hosting ?

A Virtual Private Server (VPS) offers a secure and flexible hosting alternative. It is the best way to gain a web hosting solution with dedicated resources without paying the higher costs of a dedicated server. A vps offers more security than shared web hosting package, and users don’t have to concern themselves about downtime and the resource sharing issues.

It is wise to check the amount of total resources a website will require before selecting a vps service. A cheap vps hosting package offering a tiny RAM, most of times proves to be ineffective compared to a decent shared web hosting package.

Virtual private servers are very much flexible and can be modified to suit individual requirements. VPS comes in many different sizes along with various resource allocations, support and pricing. You should opt for a vps hosting plan by making a list of your website requirements, such as the softwares you want to install, traffic you expect in a month, and the disk space your website will require.

You can always plan ahead, if you select a vps hosting plan that will permit for expansion, but it is not essential to choose and buy a web hosting plan that is way beyond your requirements and exceeds your budget. A good vps hosting provider will always allow you to upgrade your package whenever required.
