Cloud Computing - History
It is made possible by logically slicing a huge server. Typically a ‘bare-metal server’ which is a computer server by itself. These servers are purpose built for a ‘single-tenant’ . To make cloud computing possible this bare-metal server is cut across for multiple customers by a concept called Hypervisor. This allows one or more virtual machines to be served to each customer, through virtualization.
AWS a Brief
Every AWS AMI, Amazon Machine Image – is a special type of virtual appliance that is used to create a virtual machine within the Amazon Elastic Compute Cloud – EC2 . This uses the Xen hypervisor on bare metal to meet the virtualization.
Xen offers two kinds of virtualization:
- HVM : Hardware Virtual Machine – VMs running on top of their hypervisors are not aware that they are sharing processing time with other clients on the same hardware.
- PV : Paravirtualization – is a virtualization technique that presents a software interface to the virtual machines which is similar, yet not identical to the underlying hardware–software interface. You can typically notice HVM/PV while launching your EC2 instance.
