Physical Server Deployments, Virtualizations, Cloud

• Problem
  
• To use the hardware effectively, we have a software introduced to perform virtualization.
  
• Hypervisors are the software used to create virtual machine
  
• For peak hour demands we might need more virtual machines and increasing the virtual machines that run the same application. is called as (Horizontal Scaling)
• This is where cloud can help.
  
  
• Azure has two major services for handling virtual machines
  • Virtual Machines (VM) => for individual vm creating
  • Virtual Machine Scale Sets (VMSS) => when we need automatic scaling or fixed number of vm’s running your application all the time
• Created one Windows Server VM
