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 brings 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.

I was running a small private weather website in AWS and the satellite images got "picked up" by a news website and they regularly use them during major weather evenings. AWS' 12c per GB of outbound network traffic made things expensive and VPSServer makes this a lot more manageable and has excellent data volumes included with the price of the VPS. I also get many more CPUs for the price compared to AWS, so I am a happy customer.

VPS has a dedicated IP address, which you do not have to share with other users. This is important, as in shared hosting many domains are under one IP address and if one website fails, the whole IP address is added to the blacklist. Also, in case of shared hosting, your website's load can be affected by another user on the same server. It means that if your "neighbor" website is loading or it is inaccessible for various reasons, your website loading time can be increased too.
Use Virtual Network to build your services that rely on Azure cloud services and Azure Virtual Machines. Use Azure web roles for your front end and virtual machines for backend databases. Combine platform as a service (PaaS) and infrastructure as a service (IaaS) in a virtual network to get more flexibility and scalability when you’re building apps.
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.
