Shared hosting is like you are living in a room with a lot of friends. It means you must fit in the same room and you must split the cost of several things because it is affordable and cheap. However, several individuals are sharing the same space, it means everyone needs to live within a space with restricted resources among them. You will have to use the same things (that sounds a little unhygienic).
You're an experienced developer who wants full control over your environment. We're giving it to you! You get root access so you're able to access and edit all of your server's files! You get to choose your Linux OS and can even re-load your server with a new operating system on demand! You also get boot, shutdown and reboot control. Now we're talking about serious hosting!
The leftover disk space in a VPS plan can be used to store private backups of important files. It’s cheaper to use cloud-based storage The Cloud Storage Showdown - Dropbox, Google Drive, SkyDrive & More The Cloud Storage Showdown - Dropbox, Google Drive, SkyDrive & More The cloud storage scene has heated up recently, with a long-awaited entry by Google and a revamped SkyDrive from Microsoft. Dropbox has gone unchallenged by the major players for a long time, but that’s changed... Read More from a price-per-gigabyte perspective, but if you’re already using a VPS for some other reason and you have leftover space, you might as well think of it as free file storage.
Perhaps the best way to approach the virtual server is the idea of a virtual machine. A VM allows you to run an emulation of a computer within your computer, drawing on the resources of the physical one –  disk space, RAM, CPU, etc. This tactic allows you to run an entirely separate operating system (OS) solely for the purposes of the VM, even if its type and version of OS are identical to what’s on your hardware.

During the Nutanix demo, Andy did what he does better than anyone I know – he drew a full stack of Nutanix on the whiteboard and covered the hyperconverged technology from end to end. I was intrigued by Andy’s presentation of hyperconvergence. For more information see the results of Gartner’s Peer Insights: Nutanix vs VMware Review. Some folks say Nutanix is the solution to the VMware tax.

Be careful of what we call “managed in name only” or MINO hosts. They’ll claim to offer managed hosting but will act more like an unmanaged host in that they won’t proactively spend time on your account. You can usually judge the quality of a managed host when you’re first signing up as the good ones will go out of their way to understand your business and to tailor their offering to your needs instead of just trying to sell you their most expensive “package”.
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.

KVM virtualization gives customers more possibilities of management and server configuration. As it is a kernel based VPS hosting, kernels can be upgraded and modified by installing kernel modules. KVM has its own virtualized hardware, and the virtual server acts as a physical server. There is a possibility to set up a container-based system, such a Docker or Kubernetes to create OS level based containers on the KVM server.
System virtual machines grew out of time-sharing, as notably implemented in the Compatible Time-Sharing System (CTSS). Time-sharing allowed multiple users to use a computer concurrently: each program appeared to have full access to the machine, but only one program was executed at the time, with the system switching between programs in time slices, saving and restoring state each time. This evolved into virtual machines, notably via IBM's research systems: the M44/44X, which used partial virtualization, and the CP-40 and SIMMON, which used full virtualization, and were early examples of hypervisors. The first widely available virtual machine architecture was the CP-67/CMS (see History of CP/CMS for details). An important distinction was between using multiple virtual machines on one host system for time-sharing, as in M44/44X and CP-40, and using one virtual machine on a host system for prototyping, as in SIMMON. Emulators, with hardware emulation of earlier systems for compatibility, date back to the IBM System/360 in 1963,[7][8] while the software emulation (then-called "simulation") predates it.
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.
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.
