Benefits of Virtual Private Server (VPS Hosting)

Admin    VPS Hosting     Benefits of Virtual Private Server, cheap vps, Virtual Private Server, VPS, vps hosting, Why VPS

If you are serious about your online business, you may wish to take a closer look at VPS hosting. What exactly is VPS? And how does it benefit your business?

VPS is short for Virtual Private Server. A VPS hosting plan gives you complete control over your own hosting account. It’s almost as if you are the owner of a dedicated server. However, a VPS is not the same as having a dedicated server. It is just a virtual segment of the server. In other words, there may be other hosting accounts on the same machine, but these accounts do not impact your VPS account. The virtual segment is created using special software, and the goal here is to allocate dedicated resources to you without having to setup a new machine.

This allows you to enjoy all the benefits of running a private server without having to undertake the costs of setting up a dedicated server. A VPS hosting account may cost you between $50 to $100, depending on the amount of resources allocated to your account. A dedicated hosting account can easily cost you $200 or more each month. So by using a VPS account to host your sites, you enjoy a massive savings of 50% or more upfront. Now let’s take a look at some of the benefits of owning a VPS account.

1) Administrative rights and access.

A VPS account gives you full admin rights. It’s almost as if you are running the server in your own home. You are given virtual access to the root directory of the account. You may then install and configure the server anyway you like. Remember, whatever you do doesn’t affect all the other accounts on the same server (and vice versa). So you are free to pretty much do what you like with the server.

This is important for some webmasters because some software require special components to function properly. But you can’t install third party components in a shared hosting environment. You can, however, buy and install third party components on a VPS account.

2) Cost savings.

Compared to a dedicated server, a VPS hosting account offers immense cost savings. You do not, however, enjoy the same amount of resources that you get with a dedicated server. For this reason, a VPS account is ideal for mid-sized websites

. You don’t really need a full-fledged server to run your site, but you do require dedicated resources. In this case, a VPS account is perfect.

3) More reliability.

In shared environment, you never know when an inexperienced webmaster may bring the whole machine down. This happens from time to time because webmasters upload scripts that hog too much resources. If the server goes down, everyone is affected. However, if you are using a VPS account, you don’t have to worry about what the other webmasters are doing. The resources are dedicated to your account and you will not be affected adversely. If reliability is important to you, paying a little more for a VPS account may be worth it.

What is Vps Hosting?

Admin    VPS Hosting     Virtual Private Server, VPS, vps hosting

Virtual Private Server (VPS) hosting is the hosting of separate entities for different customers in a single server. This technology allows the hosting provider to partition and create multiple virtual servers from one physical server. Customers would share the server which includes the hardware itself and the connection. However, they would enjoy the benefits almost similar to dedicated hosting such as their private operating system and file system, allowing freedom of accessibility and security. Hence, VPS hosting can be considered as a hosting environment in between a shared and a dedicated hosting. Ultimately, an advanced performance and privacy can be achieved at a lesser cost than for a dedicated hosting.

In terms of control, customers would be able to access administrative tasks such as changing server configurations, installing software, hosting multiple sites and rebooting the server. Thus it is imperative that customers who require greater accessibility and security of their server to opt for this type of account. If you are planning to move from a shared to a dedicated hosting environment without having to incur significant rise of costs, the logical step is to move to VPS hosting server first. With the price dropping to as low as $10 per month for some hosting providers, VPS hosting is definitely a worthy proposition for a lot of users. Since the operating system and file system are separate for each customer, users can expect a guaranteed share of the server in terms of CPU, disk input/output and network.

For those intending to do reseller hosting, you will be able to have more control on the services that you can offer, therefore having the edge over other resellers in the market. For web developers who plan to set up a social networking website or function-rich blogs, VPS hosting would be a suitable option. It is also a good choice for webmasters who are already comfortable with managing a shared hosting and intend to upgrade their skills on server management, without being exposed to the risks of running a fully dedicated server. Webmasters would be able to install custom applications or change modules for the server. They would also be able to enjoy guaranteed security over the websites that they manage since every VPS environment has its own software to run its hosting and is allocated its own portion of resources, hence reducing possibilities of intrusion.

In summary, VPS hosting is the perfect hosting solution for customers who want the control and flexibility of dedicated hosting at a cost similar to shared hosting. With this technology that enables webmasters to enjoy the best of both worlds, it is indeed a great value proposition.

Virtual Private Server (VPS) Web Hosting

For those webmasters whom desire more control over their website hosting environment, virtual private server, or VPS web hosting is a viable alternative. The extremely low cost web hosting service provided by shared hosting has it’s limitations. Because a single server is home to possibly several hundred websites, some of their resources such as CPU, disk space, and bandwidth have to be shared by all of the individual hosting account customers. These shared resources normally are not necessarily an issue for small to medium sized sites. The major limitation is the restraint of control over system level software such as http servers, mail servers etc. You don’t have options such as being able to select a different operating system and you cannot compose programs or do administrative functions like putting Spam filters or firewalls in place. For most of you this isn’t a problem because you either don’t know how or don’t want to do that stuff anyway! The majority of website owners don’t have any interest or the skills to deal with this sort of work and are content to leave it to the hosting company. Those who want or need more control over their server situation or desire to try out new software, however, can attain this level of management with a Virtual Private Server.

A virtual private server (VPS) is a physical server that has been split into several virtual machines by software. Each of these divisions acts as an autonomous dedicated server. The physical resources such as RAM, CPU and disk space are still shared, but each VPS acts independently of the others. Each VPS can even have a different operating system and can be configured any way you want. The central asset of VPS is that it lets each VPS administrator have access to the root level of his virtual server. This accessibility allows the web master to install and remove software, set permissions, and create accounts. You have the same control as if it were a “real” server. In addition to allowing you a greater degree of control over your hosting environment, a VPS is more secure than shared hosting. If a hacker were to gain access to the root of a shared server he could wreak havoc on any or all of the websites on that server. A VPS is sub-divided in such a way that even if a hacker were to obtain entry through one account, he could not get to the others. Each VPS is invisible to the others and there is no way to set up root level access from one VPS to another.

The most common configuration of virtual private servers (VPS) is to evenly divide all of the physical resources by the number of accounts. So if there are 10 virtual servers, each would be allocated 10% of the total bandwidth, CPU, memory and disk space. The control that a VPS account provides can get you into a real mess if you don’t understand what you are doing. You are capable of deleting files, setting permissions improperly, allowing virus-laden software on the system and, in general, really putting your website in jeopardy. If you don’t have the skills necessary to administer a server, or are not able to get assistance, VPS is not a wise choice for you. If your website has grown beyond the capabilities of shared hosting, then, VPS may offer an affordable option to dedicated hosting. Be certain to ascertain how system resources are divvied up, how many VPS accounts are on each physical server, how you upgrade if needed, and what the choices of operating systems are.

Virtual Private Servers (vps) – a Guide

Admin    VPS Hosting     Virtual Private Server, Virtual Private Servers, VPS

Web Hosting, if tarred with as broad a brush as possible, is split into Shared and Dedicated Hosting. There are those who purchase a space on a server for their own use, and then there are those who just buy the server. A bit like buying a plane ticket, or buying a plane (except the difference between a return to Oslo and a Cessna are a bit more pronounced).

There is a bridge over these troubled waters, however. It’s known as VPS (Virtual Private Server – it’s also known as VDS, Virtual Dedicated Server, but that’s not as common, presumably because it leads to confusion with old fashioned displays and sounds like something unsavoury you might catch on a night out in Calcutta). VPS allows freedom from the constraints of Shared Hosting, without the expense or expertise of a Dedicated server.

A Shared Hosting server typically has an operating system installed on it, and the host then installs the software they want – they set the server exactly as they like it, and then customers pay them certain amounts of money to purchase a little space on the server. The customer has as much control over that space as the host will let them, and their performance will be based on however many customers are Sharing the server (hundreds, perhaps). Remember that a server is just like your computer at home or at work – and just like your computer, it has a certain amount of memory and a certain speed of processor, and it can only do so many things at once before it has to start putting people in a queue (this is the point where your site may seem slower than usual).

A Dedicated server works the same as a Shared server, except the owner of the server has far more control over what is on their server. Like the hosting company with the Shared server, the owner of the Dedicated can pick the operating system, what software is installed, and how many sites run on the server. If a Dedicated server is set up specifically for one site and is configured for that site alone, that site will run considerably faster than a site on a Shared server. It doesn’t have to share resources and it can be built purely for the purposes of running that site.

VPS sits between these two types of hosting. There are several kinds of VPS, but we will focus on software VPS. In this instance, the host will buy the server, and install an Operating System (OS) on it. They then use another program (i.e. Virtuozzo) to create several isolated Virtual Servers (sometimes known as Containers) on the server. Each of these Containers is a Virtual Server – they function as if they were stand-alone, Dedicated Servers, when in actual fact they are a more advanced form of Shared hosting!

Compared to Shared hosting, VPS has many benefits. To begin with, Shared hosting comes with no performance guarantees. That’s not to say that Shared hosting is slow – it’s just that some sites require a lot more resources than others, and a few busy or intensive sites on a full Shared server could well impact the performance of everyone else (try opening a few basic programs on your computer at once , keep them open, and then see how well your computer runs when you start a virus scan – those basic programs aren’t so responsive now, are they?).

With a VPS, your Container will come with a guaranteed proportion of the server’s resources. This usually comes in the form of RAM (Memory) available – for instance, your VPS might come with a guaranteed 256 or 512 MB of RAM. This means that, regardless of how many people there are on the server, regardless of how busy their sites are, you always, always have that much memory available for you to use. Some companies also advertise the ‘burst’ memory available to you as well. This is essentially the memory that you could conceivably use, assuming that everyone else isn’t using their quota. However ‘burst’ memory is a subjective term – as there are no guarantees on how often this memory will be available to you (beyond the length of a piece of string), it’s more a fancy figure to impress potential customers with.

As a Container is purchased with a guaranteed RAM quota, there will be far fewer customers sharing a VPS server than there would be sharing a, er, Shared server. So the CPU won’t be divided between as many clients and their respective demands on it, so speeds will improve and the load on the CPU will decrease. All in all – your hosting will be noticeably faster. Again, some hosts will advertise CPU preferences, server contention rates etc., to demonstrate how the more expensive VPS packages will take preference to some degree over the cheaper packages when requesting resources from the CPU. How much this makes an impact on your decision to buy that VPS or not is up to you; many hosts don’t make any preferences between packages whatsoever.

The other major benefit to a VPS is the extra control that you will have over your hosting. If you’ve managed to find someone who does hardware VPS, then you’ll be able to pick your own OS as well (hardware VPS, essentially, creates the VPS on a hardware level rather than a software level – the good part; you can do whatever you like with your VPS – the bad part; the hardware, rather than shared, is divided, so instead of having the use of, for instance, a 2gHz processor and a guaranteed 256MB of RAM, you get a .5gHz processor and a guaranteed 256 MB of RAM if 4 people are sharing your server). From here you can configure your hosting as you see fit – customise your PHP settings, install PHP x, Zend whatever, Hardy Heron and/or Peggle (not recommended for a work environment). Even better, as your VPS is essentially a Virtual Machine, you can take snapshots of your entire VPS – so your whole account can be backed up into a single file, and then should something go horribly wrong, you can use the snapshot to restore the VPS in its entirety.

VPS will, of course, cost more than Shared Hosting, but on the flip side of the coin it is considerably cheaper than a Dedicated server. If performance is more of an issue for you than cost then a Dedicated is the way forward – a VPS will never be able to command the amount of resources that a Dedicated server used for the same purpose can. But as a cost-effective solution to providing a significant performance boost to your hosting, as well as allowing yourself a greater degree of control – VPS is hard to fault.

*Please note – I’ve been to Calcutta. I’m not implying that the place is unsavoury, disreputable, or otherwise trying to smear the good name of Calcutta in any way – it just seemed to round the sentence off nicely!

Why is Vps Better Than Shared Hosting?

Admin    VPS Hosting     Virtual Private Server, VPS, VPS vs Shared Hosting

If you’re planning to start an on-line enterprise, or if you’ve already got one, you’ll know that there are many different web hosting plans out there – each with its own set of advantages and disadvantages. The least expensive is very popular shared hosting with hundreds of web sites all sharing a single, very large hard drive. However this type of Hosting is not always well suited for all sites, especially for high traffic sites, because it is not always possible to isolate each website from other sites that share the server. The really big sites employ dedicated servers. One company. One server.

In between these two options is virtual private server, or VPS. VPS is less expensive (much less) than a dedicated or private server, and offers more freedom and many more options to a growing on-line business than shared hosting. With a Virtual Private Server, each web hosting account receives their own operating system. Users can configure these components without affecting other users on the same physical machine because they are working within their own virtual server. Moreover a VPS hosting environment can be smoothly scaled to even more powerful physical hosts as demand increases. In the long run, hosting on a VPS can significantly reduce the total cost of ownership.

VPS isn’t suitable for every site owner. Some people wish to host a low-to-moderate traffic website and are happy with the level of control offered by a web hosting control panel like cPanel or Plesk. These individuals will prefer Shared Hosting for its perceived simplicity and ease of use: they generally do not have linux system administration experience and they are not interested in picking up any. Other have outgrown their shared hosting account or aren’t happy with site performance (30-second download times) then it’s definitely time to move up to a VPS account. A good web hosting company will help you migrate from your shared account to a VPS account without any breakdowns or hassles.
Do I Need VPS? If you plan to expand, offering more products and services, then consider a VPS plan even as a start-up. The difference in price between a good shared hosting plan and a good VPS plan is negligible in the whole bang-buck equation.

These are the main advantages:

PERFORMANCE
Shared server accounts are always dependent on the performance and good behavior of neighboring accounts. If one account violates their terms of service and sends out a mass-mailing of spam, this will load the server and negatively impact the performance of all accounts on that server.
VPS have guaranteed resources. One customer can not run away with a large share of the resources. You service will run reliably and predictably. If you have a bad VPS neighbor, they will tend to impact only their own account, as each account appears like a separate server to the Internet. They will not be able to grab your memory when you need it, get your server blacklisted, etc.

HIGH CUSTOMIZABILITY
Virtual Private Servers are very feature rich. They are functionally equivalent to a dedicated server. Some applications require that certain ports and/or protocols be opened or closed in the firewall. With Shared hosting, custom firewall configurations are not advisable for security reasons. Under the VPS, custom firewall configurations are feasible because of the partitioning between customers.
With a VPS, you can close ports using the IPTables feature.
You have your own IP Address.
You have Root Access.
Freedom to reboot your VPS at any time.
You can customize services such as web, mail, database, panels, domains
and much more…
The only limitation is you are not able to install your own kernel. This is due to the nature of how a VPS work.

SECURITY
Shared hosting is inherently difficult to secure completely. If an account on a shared server is broken into, the criminal may cause damage to the entire server, causing extended outages. If a spammer causes the server to get blacklisted with Spam organizations, this may impact other accounts that produce legitimate mailings until the server is whitelisted again.
VPS accounts are insulated from each other, minimizing the risk of unauthorized access from hackers as well as other customers. The isolation of your account also minimizes the risk of being impacted by a DoS attack that was intended for someone else.

SCALABILITY
Virtual private servers are inherently scalable – whether you need a minimal allocation to run a simple e-mail server or virtual private network end-point or a webserver with enough resources to support extensive database applications and heavy traffic, there is always a VPS hosting plan to meet your needs. Moreover you can anytime easily downgrade or upgrade your service with very little or no downtime!

UNLIMITED WEBSITES
Another advantage to VPS is the ability to manage numerous web sites. You won’t run into problems with hardware sharing even if you run a dozen different sites. Your access to server assets is assured through the use of server-side software such as Apache Virtual Hosts and similar VPS packages. VPS hosting plans are a bit pricier than shared hosting. But with more and more sites coming on-line (approximately 6,000 a day!) VPS offers better value for your server dollars when you can host as many sites as you want. When considering VPS plans, amortize the monthly costs over the number of sites you anticipate creating. You’ll quickly see that VPS monthly costs are consistently lower than shared hosting on a per site basis.

There may be a little downside to VPS for some people. VPS = more responsibility. That means you are responsible for many of the software installations, site maintenance, site security and many of the other responsibilities that come with on-line business ownership. If you don’t know much about server side administration, VPS may be a bit more than you want to take on yourself. This is something to farm out to an expert if you’re not familiar with maintaining a VPS, but you still need the power and control of VPS.
The solution  – get a managed vps, the hosting provider will take care of those things for you and you can pay full attention to your websites content.

OpenVZ VPS

What is OpenVZ?

OpenVZ is a complete server automation and virtualization solution developed by SWsoft. OpenVZ creates multiple isolated Virtual Private Servers (VPS Hostings) on a single physical server to share hardware and management effort with maximum efficiency. Each VPS Hosting performs and executes exactly like a stand-alone server for its users and applications as it can be rebooted independently and has its own root access, users, IP addresses, memory, processes, files, applications, system libraries, and configuration files. Light overhead and efficient design of OpenVZ makes it the right virtualization choice for production servers with live applications and real-life data.

The basic OpenVZ VPS Hosting capabilities are:

Dynamic Real-time Partitioning –
Partition a physical server into tens of VPS Hostings, each with full dedicated server functionality.
Resource Management –
Assign and control VPS Hosting resource parameters and re-allocate resources in real-time.
Mass Management -
Manage a multitude of physical servers and Virtual Private Servers in a unified way.

Basics of OpenVZ and VPS Hosting Technology

This figure presumes that you have a number of physical servers united into a network. In fact, you may have only one dedicated server to effectively use OpenVZ for the needs of your network. If you have more than one OpenVZ-based physical server, each one of the servers will have a similar architecture. In OpenVZ terminology, such servers are called Hardware Nodes (or HN, or just Nodes), because they represent hardware units within a network.

OpenVZ is installed on Fedora Core 3 or 4 or Red Hat Enterprise Linux 4 configured in a certain way. For example, such customized configuration shall include the creation of a /vz partition, which is the basic partition for hosting Virtual Private Servers and which must be way larger than the root partition. This and similar configuration issues are most easily resolved during Linux installation on the Hardware Node.

OpenVZ is installed in such a way that you will be able to boot your computer either with OpenVZ support or without it. This support is presented as “OpenVZ” in your boot loader and shown as OpenVZ Layer in the figure above.

However, at this point you are not yet able to create Virtual Private Servers. A Virtual Private Server is functionally identical to an isolated standalone server, having its own IP addresses, processes, files, users, its own configuration files, its own applications, system libraries, and so on. Virtual private servers share the same Hardware Node and the same OS kernel. However, they are isolated from each other. A Virtual Private Server is a kind of ‘sandbox’ for processes and users.
Different Virtual Private Servers can run different versions of Linux (for example, SuSE 9.2 or Fedora Core 4 and many others). Each VPS Hosting can run its own version of Linux. In this case we say that a VPS Hosting is based on a certain OS template. OS templates are packages shipped with OpenVZ. Before you are able to create a Virtual Private Server, you should install the corresponding OS template in OpenVZ. This is displayed as OpenVZ Templates in the scheme above.
After you have installed at least one OS template, you can create any number of VPS Hostings with the help of standard OpenVZ utilities, configure their network and/or other settings, and work with these VPS Hostings as with fully functional Linux servers.

What is VPS?

When you browse through some of the hosting types that your Web host offers you might stumble upon a listing for VPS hosting.

What is it?

Well, I am sure I will not cover every inch of what a VPS hosting account is, but let me go through the basics so we don’t need a degree to understand what it will and will not give you.
VPS stands for virtual private server. It is sometimes also referred to as a virtual server or a virtual dedicated server. It takes one big server and partitions it off into several smaller servers. Each VPS hosting account can have its own operating system and can be rebooted without effecting the other accounts on the machine.

Now that you know what it is, what is it good for?

These types of hosting accounts are usually used as a stepping stone between your basic shared hosting accounts and dedicated hosting accounts. You get all of the benefits of having your own dedicated machine, but you still have some limitation as to what you can do with it. If shared hosting is a light snack, and dedicated hosting is a three course meal, you can consider VPS hosting a regular sized dinner.

Now where with a dedicated machine, your RAM and CPU usage would be a little less limited, with VPS hosting you are more in the boat with shared hosting. You will be limited by your Web host in disk space, bandwidth, CPU and RAM usage. Now where a VPS is helpful is when you need the benefits of dedicated hosting such as certain types of script setups and account access.

So as I said before, this is a much needed plan in between your shared and dedicated hosting. It allows you a little more flexibility than a shared hosting account, but limits you more than a dedicated account would.

What is VPS

Admin    VPS Hosting     cheap vps, linux vps, top vps hosting, Virtual Private Server, VPS, vps hosting, vps hosting comparison, vps hosting reviews, VPS Review, VPS Reviews, windows vps

A Virtual Private Server (VPS) is a hosting environment that combines the benefits of both shared hosting and dedicated hosting. It does this by creating a virtual server that runs inside a hardware server via a specially designed partition.

Each Virtual Private Server partition runs its own operating system in a secure and private environment and cannot be accessed or interrupted by its neighbours.

This system gives you the same level of root access as a dedicated server whilst sharing the cost of the hardware. With a VPS you are virtually running your own server but at a fraction of the cost.

The flexibility of a dedicated server

Users share system resources, such as the CPU and memory, but unlike shared hosting (a virtual host on a shared hardware server ) the file system is fully partitioned. This means you get a guaranteed share of the server’s resources, while full root access allows you to completely customise the virtual server, adding or changing modules and installing your own software.

Highly cost effective

Because a single physical server is shared between several users, the cost of a virtual server is small when compared to the price of a dedicated server. But the level of flexibility is similar (although you’ll still need a dedicated server for really demanding applications or high-traffic sites).

How much technical knowledge do I need?

All our VPS options include the Plesk control panel, which makes it easier to administer your websites and services.

However, because a VPS gives you root-level access, allowing you to install whatever software you like, you will need some technical knowledge and understanding of how servers work to run a VPS effectively.

The inclusion of the very latest range of software and control panels for Windows and Linux is accompanied by price reductions across the range so we’re increasing performance, features and value at exactly the same time.

Powerful partnerships working for you
