This is a low cost option for the hosting company and they will usually offer some kind of data protection using a RAID system where data is copied across multiple disks. This is an entry level solution but one issue is that the server itself represents a single point of failure. It could be that the power supply fails which brings the server down for example.
The NDV cloud platform provides a consistent, integrated, and configurable security management framework, utilizing security mechanisms in individual components and security services across the integrated solution. NDV’s security mechanisms include identification and authentication, access control, authorization and auditing, and use of secure communication protocols. Additional security features such as DDoS mitigation and anti-virus protection can be opted for as per requirement.
The really good thing about the VirtualBox is that is completely free it even works on multiple versions. So if you had a Linux server you could actually also run VirtualBox same environment as this here so where it’s now booting Windows for the first time for real after installing it so put in the username I’ll just call this one Windows 7. I have to type in a password and a hint so same password cause I don’t need to put in a Windows key and since it’s so faster install I would just blow away this one when windows actually half-hour months won’t work any longer it’s all for testing anyway.
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.

All the features I've detailed to this point are valuable to the web hosting experience, but none matches the critical importance of site uptime. If your site is down, clients or customers will be unable to find you or access your products or services. It doesn't matter how great the features are, or how good it looks; if your site is down, it might as well not exist.
Our VPS Hosting plans all come with a high availability feature that essentially takes your VPS container, and empowers it with a cloud infrastructure. How does this work? We put a premium on your server's uptime, so we created an infrastructure of redundant hardware clusters that provides your partition with real-time redundancy. If for some reason there is an error on your server, there is another server in the cluster with that backup information ready to spin up. We utilize Virtuozzo, a virtualization solution built on top of OpenVZ.
As for learning to manage a VPS on your own, the best advice I can give is just to dive right in. Set yourself little goals and try to accomplish them, such as setting up a firewall or taking regular backups. If you get stuck, ask for help on Quora or look for an answer on Google. It can seem complicated when you’re first starting out, but if you stick with it then you’ll get there. There are plenty of talented self-taught system administrators out there and there’s no reason why you can’t be one of them!
Amazon VPC provides advanced security features, such as security groups and network access control lists, to enable inbound and outbound filtering at the instance level and subnet level. In addition, you can store data in Amazon S3 and restrict access so that it’s only accessible from instances in your VPC. Optionally, you can also choose to launch Dedicated Instances which run on hardware dedicated to a single customer for additional isolation.
