• The request from user travels through internet and reaches routers maintained by Amazon to enter into amazon network.
• The Silicon helps is networking hardware with in amazon.

What are the things to consider While Create a VM

• AWS has a Service for Creating Virtual Machine which EC2 (Elastic Compute Cloud).
• Each VM is often referred as an ec2 instance.
• Factors:
  • Which Operating System?
  • What is Size of EC2 instance (CPU, RAM)
  • How much storage do you need
  • Which ports of your instance are open for communication and what are closed
  • Do you want to run any script immedietly after EC2 instance is created
  • What will be the Credentials (For logging in )(Usernames are already fixed in Amazon)
  • Where do you want your ec2 instance (Region + AZ)
• Costs:
  • Charges for EC2 instances only when they are running
  • Storage Charge is calculated separately which will be on when your ec2 instance is running or stopped

Virtualization Types

• To Create a Virtual Machine from Physical Servers we use Hypervisors, Amazon also has their propietary Hypervisor which supports Virtualization
• There are two kinds of Virtualizations
  • Paravirtual (PV)
  • Hardware Virtual Machine (hvm)
