Una landing zone antes de la primera carga de trabajo
Las cuentas cloud siguen siendo manejables cuando las suscripciones, la red y los límites de identidad existen antes de desplegar nada.
Esta nota de campo se publica en inglés.
A cloud account that grows without a plan becomes difficult to reason about. Resources appear in the wrong subscription, budgets surprise at month end, and nobody can say which environment a workload belongs to. A landing zone fixes that by deciding the structure before the first workload lands.
Separate the concerns
Management groups, subscriptions and resource groups should mirror how the business actually operates: production apart from non-production, shared services apart from workloads, and cost ownership visible per team. This is mostly admin work, and it is the highest-leverage admin work in the whole cloud estate.
Draw the network first
Virtual networks, address space and private endpoints are painful to retrofit once workloads depend on them. Decide hub-and-spoke or landing-point topology early, reserve address ranges generously, and keep internet egress behind a controlled path. A diagram on one page beats ten pages of rules.
Bound identity before workloads
Management identities, break-glass accounts and conditional access belong in the landing zone, not in a workload sprint. When identity boundaries exist first, every later deployment inherits least privilege instead of negotiating it.
Manage everything as code
Terraform from day one — even for the landing zone itself. Console clicks are how drift starts. A reviewed pull request that creates a subscription or a policy assignment is auditable proof for the next security review.
