Introduction to Amazon EC2
Amazon EC2 is one of AWS's flagship offerings and allows you to launch and set up virtual servers in the cloud. These are very similar to setting up and configuring VMs in your on-premises environment, which you would configure on a hypervisor such as VMware or Hyper-V.
A hypervisor, as discussed in Chapter 1, What Is Cloud Computing?, is a piece of software that allows you to create virtual resources such as virtual servers. Depending on the capacity of the underlying hardware, you can then host multiple virtual servers on the same physical hardware. These virtual servers are granted access to actual physical hardware via the hypervisor, which carves out virtualized representations of the physical hardware components (CPU, memory, storage, and so on) into smaller virtual components, that are then presented to your virtual servers. You can access hypervisor software such as VMware and Hyper-V to create your virtual servers, selecting the virtual...
