01The Architecture Challenge

Manual tenant provisioning was slowing user onboarding and creating operational bottlenecks.

Key Technical Pain Points Addressed:

High operational risk of service disruption during production cutover.
Over-provisioned compute resources driving unnecessary cloud expenditure.
Lack of declarative configuration management and GitOps workflows.
