We regularly examine customer bandwidth and disk space utilization data in a series of statistical analyses and use the results to define "normal". Although these tests vary from month to month, one thing remains constant: 99.95% of our customers fall into "normal" range. If your account's bandwidth or disk space utilization causes any concern, you will receive an email asking you to reduce usage. We strive to provide at least 48 hours notice to allow customers to make adjustments before we take any corrective action.
It provides you with even more options, including root access, access to Apache and PHP.ini (modification of PHP variables), and much more. You can also install an SSL certificate, and all software program types. In short, you get more freedom in terms of administering and configuring your server, without the hassle of managing any physical hardware.
Traffic between Azure resources in a single region, or in multiple regions, stays in the Azure network—intra-Azure traffic doesn’t flow over the Internet. In Azure, traffic for virtual machine-to-virtual machine, storage, and SQL communication only traverses the Azure network, regardless of the source and destination Azure region. Inter-region virtual network-to-virtual network traffic also flows entirely across the Azure network.
Launch Assist™ includes 2 hours of dedicated time with one of our T3 System Administrators and can be used upon purchase for a number of different practical applications, including site migrations, server security setup, email servers, application installation, CRON automation, hardware configurations and much more.

I have some sites hosted on a shared-hosting/cpanel environment and need to make a move up. I have some experience running my own server, but it is very basic (a local box to do live testing/file serv). My question is how difficult is it to run a VPS, should I buy a managed VPS (with stuff already installed), or unmanaged (blank box), and lastly if I go for unmanaged what steps should I take to keep my VPS secure? Edit: Also how difficult is it to backup files and databases? Can it be automated?
Shared hosting: With shared hosting, your site is stored and served from the same physical machine as many other customers – possibly hundreds of them. All domains are drawing from the same CPU, RAM, and other resources.  This type of hosting is the lowest-priced option. However, your site’s speed and reliability suffer from other users, and you don’t get root access.
So that could be either a virtual machine - an operating system running inside another operating system, or a virtual private server - you rent a virtual server from a company, so you have your own internet-facing server running 24/7 relatively cheap (since it's not a real server, but one of many virtual server running on an actual server). I think he might have meant the later, since you'd have to run a snartnofe (btw I love that name) non stop to benefit from it.
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.
