Change is a good thing. Unfortunately, when you are making big changes to your site or application, there is always room for error. Live-state snapshots takes the idea of a "backup" and takes it forward to its next logical step. Taking a snapshot of your partition not only creates a backup of your files, but also all of the processes running in the background at that instant in time. This way, if you make an error or break something while making updates, you can revert your partition to that exact snapshot, providing a working, fail-safe rollback.
A VPN server is a machine on the internet that runs VPN software. A VPN client can connect to that server, and all data that travels between the client and the server is encrypted. If you wanted to connect to a website on the internet but didn’t want anyone, even your ISP, to see which site it was or the data your were sending, you could connect via a VPN. All an observer would be able to see is that you connected to the VPN server.

OpenVZ virtualization is an OS level container-based virtualization, and it has resources that are divided between users on a physical server. Each container acts like a stand-alone virtual server and can be accessed with a root (SSH) connection. As a separate server container can be rebooted separately, it also has a dedicated IP address, shared RAM, individual processes, files, applications, system libraries and configuration files. On OpenVZ, the kernel cannot be modified. It has its stable version and modules cannot be added. The good thing regarding this virtualization is a faster performance, and a lower need of resources.


Most VPS hosts only offer servers running Linux-based operating systems; you'll need to dig a bit to find Windows-based VPS hosting. This is important to note if you're planning on running software that requires a Microsoft-compatible environment. That said, Linux-based VPS hosting will save you a few bucks; Linux servers usually cost $10 to $20 less than Windows servers.

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.
A virtual private server (VPS) is created through the process of virtualization, by which a virtual replica of a physical server is created. A VPS is like having access to your own personal server with an allocated number of resources and choice of a pre-installed operating system. It is an isolated microsystem based on a shared server. Since a VPS is self contained, you have full control of your server setup and are responsible for all updates and security. You can also choose to opt for our managed service.
Managed VPS hosting is the ideal solution for both non-technical but also technically savvy people since the hosting provider takes care of any technical tasks related to the server. In other words the web hosting provider is responsible for managing the server including system upgrades and configuration and your job is to do what you are supposed to do i.e. run your website or online business.
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.

cPanel will do almost everything for you (until things go wrong) but you still need to know how to use bash and yum, how to secure your VPS, and how to troubleshoot your own connectivity issues at a minimum if you decide to roll with an unmanaged service... also, whenever WHM/cPanel sends you an e-mail alert you should read it and follow any links to WHM/cPanel documentation - our support team had far too many cPanel tickets in which the subscriber forwarded along the alert after ignoring the link which described how to solve the problem.


This is a low cost option for the hosting company and they will usually offer some kind of data protection using a RAID system where data is copied across multiple disks. This is an entry level solution but one issue is that the server itself represents a single point of failure. It could be that the power supply fails which brings the server down for example.
Vrtualbox is an alternative to using VMware or when the old days you would use Virtual PC. It allows 64-bit operating systems and Irving and especially for testing 2013 and are more advanced nav features. It’s a great product because it also performs very well. So I’ve already downloaded the VirtualBox here so I would just go through the install. And it’s one of those simple ones is just like those next-next-next. It will give you a warning here that it actually will shut down the network interface for a short second. It’s not different than what virtual preceded.
VMs on ESXi run Windows and Linux operating systems near flawlessly. It’s also a powerhouse for many sizeable virtual desktop deployments running on VMware View or Citrix XenDesktop. And more recently VMware was in the news because they will soon power Google’s Chrome virtual desktop cloud and provide access to Windows application. How cool is that!
You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your web servers that has access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.
