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.
You can choose to create additional VPCs by going to the Amazon VPC page on the AWS Management Console and selecting the "Start VPC Wizard" button. You’ll be presented with four basic network topologies. Select the one that most closely resembles the network topology that you’d like to create and choose the "Create VPC" button. Once the VPC has been created, you can begin launching Amazon EC2 instances into your VPC.
Speaking of email and limits, you'll want the ability to create an unlimited number of accounts. Should your website grow significantly, you'll appreciate being able to scale your email accounts without spending additional money. Web hosts typically place a cap on the amount of storage per email account. In other words, you may be able to create an unlimited number of email accounts, but each one may have a 10GB storage cap. Take time to investigate a potential web host's email offerings so as not to be surprised by its messaging limitations. Again, find out what the unlimited gotchas might be.
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
