With unmanaged VPS hosting, the cost is also much cheaper. It is not uncommon to find $10 unmanaged VPS plans because the web host does not have to pay for a cPanel or Plesk license and are able to minimize costs. Also, since the web host does not provide software and account support for an unmanaged VPS, the host also saves money on customer support. In the end, you'll have VPS hosting that is typically $20-30 cheaper than a managed VPS solution.

Since the 90’s VMware has been evolving. It started as a clumsy little software that used to be installed on a Windows desktop. Then from there, it changed into GSX for Windows Servers. And then again it morphed into ESX which eliminated the need for Windows and booted to a Redhat kernel. And later in version 4, it became ESXi which now runs on a custom Linux kernel.

The number of sites that you host on the server, the number of databases or mailboxes are not limited on a VPS, moreover, Hostens does not block any ports. VPS is a separate server that gives its owner the possibility to customize its settings. On shared hosting, you cannot choose any control panel or any software, as the provider has already configured it. As VPS provides full access (SSH) to VPS hosting, the customer is free to install, manage and control any software that is compatible with server virtualization.
If your bandwidth usage is high and your website seems slow to perform, you may need more resources than a shared website hosting plan provides. Shared hosting means you share everything - so you're restricted in how big your website can grow, and your available resources (disk space, bandwidth, etc) can be affected by the traffic flow and bandwidth usage of other websites running on the same server.
Connect to the Internet using Network Address Translation (private subnets) – Private subnets can be used for instances that you do not want to be directly addressable from the Internet. Instances in a private subnet can access the Internet without exposing their private IP address by routing their traffic through a Network Address Translation (NAT) gateway in a public subnet.
A VPS Server is the reasonable web hosting choice for your domains when more system resources are needed. VPS takes of the virtualization technologies to partition physical servers into several virtual machines. Virtual Private Server Hosting is the future of modern hosting as it provides the power and functionality of a high-end dedicated server but at a much lower price. Main virtualization technologies used including Vmware, OpenVZ and XEN etc. By purchasing a VPS hosting package, you get a 100% individual machine with your own dedicated CPU and RAM, and mostly root access to the hosting server. Each Virtual Server can run under its own operating system (Windows server, CentOS and other Linux distributions) or have custom configurations of its own.
With many other VPS plans, they cut off and limit your resource usage. Our Cloud VPS plans are different in the sense that they offer Burstable RAM limits. You will have a dedicated amount of RAM during low traffic periods (1.5GB for Cloud VPS-1000, 3GB for Cloud VPS-2000 and 6GB for Cloud VPS-3000), but are able to use a higher amount during high traffic surges and spikes.
InMotion Hosting's Virtual Private Servers are now using Solid State Drives (SSDs), a type of hard drive that uses no mechanical parts and provides substantial performance upgrades from traditional spinning drives. Solid State Drives give you faster read/write speeds, can handle more disk requests and can push through significantly more data than a standard Hard Disk Drive (HDD).
A VPS is not the same as a dedicated server, but it gives the illusion of being one. A good Web developer can do almost anything on a VPS that they would want to do on dedicated server, however, a VPS hosting plan is substantially less expensive, comes with technical support, and the hardware behind a VPS is not your responsibility. Sure, cheap servers can be acquired, but they will require a far larger overhead in terms of physical security and technical maintenance, security and support. Ultimately, a VPS can be the perfect solution when you need more flexibility and features than a shared hosting plan, but are not in the market for your own dedicated hosting server.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.[3]
