Before starting your journey into Azure IaaS, like in a physical world, one of the main topics which should be understood is networking. This is for many reasons, but most importantly:
- Understanding the basic topology of Azure networks enables correct placement of Virtual Machine workloads
- Understanding how deploying networks in ASM vs. ARM can affect management and functionality
- Understanding the security options within Azure helps you prevent data loss
- Understanding connectivity options helps you to optimise end-user experience
- Understanding how 3rd party appliances can enhance network features and security helps you meet regulatory and governance requirements
While it may not be immediately obvious, some decisions around networking can have a deep and lasting impact on your deployment such as being unable to move a Virtual Machine to a new network without deleting it and re-creating. As your Cloud deployment grows in size and complexity, such problems can quickly escalate and become near impossible to resolve without significant impact to your service.
This first post of the series will focus primarily on the basic topology of the Azure networks, look at the differences between networks in ASM vs. ARM, and touch on some of the core features available in Azure for securing your workloads and data.
