Regroup several landing zones in a Business Zone (Explorer)

Introduction

If you have multiple infrastructure landing zones, you may have encountered some common issues:

Difficulties to maintain a 360 dashboard to monitor all your landing zones
Enable to collect infrastructure logs to your dedicate CSOC
Provide reader or security accesses on multiples landing zones
Enable to add additional security policies related to your business

What does it change ?

By default, all the infrastructure landing zones are isolated between themselves :

A business group regroups the infrastructure landing zones in a customer management group (providing a transversal visibility to all subscriptions) and centralizes log into a transversal subscription.

How to ask for a business zone ?

Prerequisites:

have multiple subscriptions associated with a single TDFaccountID
all subscriptions should be in the same region

Access to postIT, and make a simple request mentioning this documentation. Please provide:

the TDFaccountID
the list of subscription to regroup
the custom permissions you want on the management group
the identity of the people who need access to the transversal log sink

Impact of business zone:

all the subscriptions will be switch to "industrialized" service offer
a new subscription will be created to store all the logs coming from the subscriptions

HOWTO access to my transversal log analytics ?

Let's take an example:

BZ-SHOWROOM will be the the business room
BZ-SHOWROOM - Core Services will be the transversal landing zone (added during the creation of the business zone to store all the subscription logs)

On azure portal, search for management group. You should see all the management group you have the permission on. Click on you business zone, like:
