  • Four storage accounts: 3 for storing VM's disks of each tier, 1 for storing diagnostics data.
  • One Virtual Network with four subnets.
  • 4 Network Security Group, one for each subnet.
  • External Load Balancer to load balance Web Traffic(HTTP & HTTPS) to web servers.
  • Internal Load Balancer to load balance traffic for app VM's.
  • 2 Public IP’s, one for external Load balancer and other for Jump VM.
  • 3 Virtual Machine Availability sets for Web Tier, Application Tier and Database tier.
  • One Jump VM to faclitate ssh access to all other tier VMs.
  • Multiple Red Hat Enterprise Linux VMs for each tier as per parameter value specified during deployment.
