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 major difference between a VPS and a private cloud is the location of the hardware. A virtual private server is generally hosted at an off-site, third-party web hosting provider. A private cloud is situated on site or at a data center you own. There are exceptions to this rule, however, as some cloud providers are offering hosted private clouds for users. These clouds use hardware that is solely for the use of that particular cloud and is not shared with other users.
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.

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”.

With support for Linux, Windows Server, SQL Server, Oracle, IBM, and SAP, Azure Virtual Machines gives you the flexibility of virtualization for a wide range of computing solutions—development and testing, running applications, and extending your datacenter. It’s the freedom of open-source software configured the way you need it. It’s as if it was another rack in your datacenter, giving you the power to deploy an application in seconds instead of weeks.
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.
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.
