Your Azure invoice should not be a surprise.
The cloud was supposed to be predictable. Instead a consumption spike no one flagged has produced an Azure invoice your CFO cannot explain. The estate grew organically with no Landing Zone management or governance, you are wasting roughly a third of your spend on idle resources, and a VMware or Broadcom renewal has arrived at multiples of last year. You need the cost under control, the estate managed and governed, and an owner for the hypervisor migration.
