Four Azure landing zone mistakes that cost you a rebuild
Subscription sprawl, hand-built networks, and no cost model. What we see most often when we inherit an Azure estate.
A landing zone is cheap to get right at the start and expensive to fix once forty workloads depend on it. These are the four decisions that most often force a rebuild.
One subscription to rule them all
A single subscription looks simple until you need to separate cost, blast radius, or policy. Management group hierarchy costs nothing to plan and everything to retrofit.
Networks built by hand
Click-ops networking is undocumented networking. Define hub-and-spoke topology in Bicep or Terraform, and treat the portal as a read-only surface.
Policy added last
Azure Policy applied after workloads land turns into a long list of exemptions. Applied first, it is simply how the platform works.
No cost model
If nobody owns a budget, everybody over-provisions. Tag for ownership on day one and put a monthly cost report in front of the teams who can act on it.
