In this design diagram I explain a hybrid DNS architecture on Azure. This diagram covers two scenarios: Scenario 1 with User1 (blue lines): User1’s computer is in Project1 vnet. User1 is trying to reach the file share in a different vnet (possibly in a separate subscription). User1 must rely on the DNS server in his/her…

Here is what I will cover today: Create an Ubuntu Linux VM with managed disk Generalize the VM and make it ready for image capture Capture the VM image Remove the VM Create a Virtual Machine Scale Set (VMSS) with OS managed disk from the captured image Let’s get things started: Create a VM with…
There are many ways to protect your EC2 Instances from being exposed to the Internet. One way is to give them private IP addresses and put them behind a public-facing Elastic Loadbalancer.
