The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.

Speaking of email and limits, you'll want the ability to create an unlimited number of accounts. Should your website grow significantly, you'll appreciate being able to scale your email accounts without spending additional money. Web hosts typically place a cap on the amount of storage per email account. In other words, you may be able to create an unlimited number of email accounts, but each one may have a 10GB storage cap. Take time to investigate a potential web host's email offerings so as not to be surprised by its messaging limitations. Again, find out what the unlimited gotchas might be.
Similarly, in the case of VPS, there are several users that are using the same server but they are isolated from each other. It means that no one will be affected by how much resources another is using. You will get the speed and security that you need without compromise. It is almost a perfect scenario because you will get the benefits of a private server with shared cost of services.

Virtual private servers have become a popular choice for web hosting because they offer many benefits of dedicated servers at a lower cost. They also provide the added benefit of easy scalability. Since each VPS is virtualized, the configuration can be updated with a software modification rather than a hardware upgrade. Still, dedicated servers often provide better performance since all the resources of the physical machine are dedicated to a single server.

A virtual machine (VM) is automatically assigned a private IP address from a range that you specify, based on the subnet it is deployed in. The address is retained by a VM until the VM is deleted. Azure dynamically assigns the next available private IP address from the subnet you create a VM in. Assign a static IP address if you want a specific IP address from the subnet assigned to the VM.
If you’re outgrowing your shared web hosting or simply want more control, a managed or fully managed Virtual Private Server (VPS) is the next logical choice for your hosting needs. It gives you more freedom with root access to Apache and PHP, plus you can install an SSL certificate, as well as any type of software – all without the responsibility of a dedicated server.

VPS can be a perfect solution for businesses that want many of the features of a dedicated server but don't have the resources to physically host, support and maintain the server hardware. A shared environment won't offer you the same bandwidth or Web hosting space that a VPS will be able to support and there are also many more constraints on the software you can run in a shared hosting environment. In contrast, a VPS will give you the freedom to install, delete, reboot and do all the functions as if you have your own server. You also get an increased level of security as each VPS is isolated and completely separate from other Virtual Private Servers on the same physical server. The environment is secure and protected and each VPS can be rebooted or stopped independently – even if a hacker infiltrates one VPS there is no access to the others using the same physical server.


VPS has a dedicated IP address, which you do not have to share with other users. This is important, as in shared hosting many domains are under one IP address and if one website fails, the whole IP address is added to the blacklist. Also, in case of shared hosting, your website's load can be affected by another user on the same server. It means that if your "neighbor" website is loading or it is inaccessible for various reasons, your website loading time can be increased too.
Lastly, arguably the most significant advantage of VPS hosting comes at the highest price. You get root access and unparalleled control of the resources granted. That means that you can install a wide range of operating systems, work on resource-heavy projects and do much more, than with shared hosting. But sadly, the customer support team will only help you with questions relating to VPS hosting management and other back-end related queries.
WHM's Backup Configuration section is one of the most powerful and vital tools for an administrator of multiple sites. It allows you to manage each of your individual cPanel backups separately, giving you the choice of backup cadence (daily, weekly, monthly and manually) and location. Preserving your clients business-critical files, data and site content is of the utmost importance. Work with your clients on implementing a backup schedule and location that is appropriate for their site(s) and make sure they have the peace of mind that their data and site material are safe.
In this case, providers do not offer any help in case any problems are encountered with unmanaged VPS accounts. The customers should, therefore, have a thorough knowledge of Linux operating system and understand the ways to control the VPS so as to ensure uptime, reliability, and server stability. There may be problems related to resources, software, performance, or configuration- all of them have to be handled by the clients themselves. The web host will only look into problems related to network or hardware in case of unmanaged hosting.
Managed VPS plans offer a managed environment similar to our shared hosting accounts, but with increased resource availability. If you are outgrowing a shared hosting environment, but are not ready yet to make the leap to a dedicated server, you should consider a managed VPS. This plan is also a good option if you need certain customizations that are not provided with shared hosting plans, but you would still like A2 Hosting to handle configuration changes, software upgrades, and other system administration tasks.
In a dedicated hosting plan, a client leases or rents a physical server from a hosting provider. With Dedicated hosting plans, the client has complete control of the physical server and access to all its resources. This is a good fit for companies that have websites that expect a high amount of traffic, that are running intensive CPU applications, and that are hosting enterprise CMS sites.
If you'd like to run a VPS, I'd suggest you to look for a managed one with cPanel. cPanel is a piece of software that facilitates a lot configuring the server, while managed means that the support guys will help you with initial configuration of the server, and also help you out with config/upgrades whenever you need help. It's a bit more expensive than non-managed, but if you don't know how to manage/administer a server, than it's essential. You can find a decent managed VPS in USA from 20 $ and up.
The fun part starts when you try to secure your server. I configured CSF (ConfigServer Security & Firewall) and cPHulk Brute Force Protection to make sure the server is secure. As i am responsible for the security of my own server, i am always having to spend valuable time to stop any attack or hacks. I usually get notifications of hackers trying to get in but the server hardening work has made it impossible to hack. The only thing is, now, i wouldn't mind paying the extra to get a managed server so i can use the time elsewhere.

I use the recommended setting I’ll go select Eastern time zone. Yeah and my network is a working Network and it’s now finished and it’s inside Windows 7 and it’s installed now of course you need to run the Windows Update also but before I do anything else are going to install the VirtualBox Edition that makes the Mouse better and seamless resizing of the screen and think that one so install what is called guest additions down here and take a few seconds before it shows up but it basically put in a CD in the CD ROM Drive for this VirtualBox and then it will run the software from the CD so the old PC essence is just finished installing Windows I guess so I want to run the VirtualBox Windows additions and that’s fine and I’ll just check this one that I want to trust it all the time so in future updates of VirtualBox I don’t have to check that I want to run it here and that was installing the VirtualBox additions in here so go ahead and reboot so now in Windows and of course I could choose another Drive in here I just going to remove that one because I don’t need the VirtualBox one.
VPS is short for a Virtual Private Server, which refers to the partitioning of a physical server into multiple servers. You can think of a VPS like a Dedicated Server, where you can enjoy all the components a Dedicated Server offers yet you pay a lower price. Each VPS also features its own OS (Operating System) and allows for separate rebooting. Since each OS receives a specific share of the resources from the physical server, each one is isolated from one another and cannot interfere.
A Virtual Private Server (VPS) uses virtualization software to partition physical servers into multiple "virtual" servers—each having the ability to run its own operating system and applications. VPS is not for everyone, but is quickly becoming the hosting preference of choice for advanced Web developers who require root access to the server to run their own software.
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. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.[1]
