Thanks for the Wonderful Overview. I have three Questions. 

Q1) As part of the initial onboarding process, ISOC requires an Azure Subscription. What resources do ISOC deploy in the Azure backend. What Location will those resources get deployed?

Q2) Post 90 days what happens to the logs. Can these logs be archived. If yes, what archival solution is been used?

Q3) Is it possible integrate the Data Lake with ISOC?
