A VPN server is a machine on the internet that runs VPN software. A VPN client can connect to that server, and all data that travels between the client and the server is encrypted. If you wanted to connect to a website on the internet but didn’t want anyone, even your ISP, to see which site it was or the data your were sending, you could connect via a VPN. All an observer would be able to see is that you connected to the VPN server.
You can periodically backup your mission critical data from your datacenter to a small number of Amazon EC2 instances with Amazon Elastic Block Store (EBS) volumes, or import your virtual machine images to Amazon EC2. In the event of a disaster in your own datacenter, you can quickly launch replacement compute capacity in AWS to ensure business continuity. When the disaster is over, you can send your mission critical data back to your datacenter and terminate the Amazon EC2 instances that you no longer need. By using Amazon VPC for disaster recovery, you can have all the benefits of a disaster recovery site at a fraction of the normal cost.
A key aspect of VPS internet hosting is its virtualization capabilities. With VPS, the hosting provider divides each physical server into multiple smaller virtual servers with private and dedicated RAM and hard drive space. This provides site owners with a more isolated hosting environment without disruptions from other clients sharing server space.
Which VPS hosting plan to choose between a managed VPS and unmanaged VPS? Generally speaking, unmanaged VPS hosting is less expensive than managed VPS hosting when you compare plans that have the same allocated resources. One of the main reason is that your hosting provider offers less support on unmanaged VPS, thus they charge less for the service. If you are well-versed in VPS hosting and you have a lot of time planed for the VPS server, you can go for a unmanaged VPS. Otherwise, you should get a managed VPS. Some of the tech issues you may need to know if you choose unmanaged VPS include but not limited to: VPS security, software update and patching, LAMP server configuration (linux, apache, mysq, php), DNS configuration, control panel setup, SSL certificates creation, website setup, server backup, etc.
Traffic Handling Users of the server may be hampered by an excessive number of requests from a webpage or application. Your website may become very slow or even temporarily stop. Because this system has its own piece of server capacity that other users can not access, you will not be hampered by other websites or applications. The performance of your website will naturally become a little better and more reliable. The question of being hampered by other websites or applications do not arise at all.
For packages supporting unmetered disk space or data transfer (bandwidth), we do not have defined limitations. These resources are "unmetered", meaning you are not billed according to the amount of disk space or bandwidth used. While of course these resources are not infinite, we believe our customers should have all the resources necessary to build an online presence and 99.95% of customers will have more than enough disk space and bandwidth to meet their needs.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
