Defining variable management and tracking strategy for all services per environment in ADO
Should have a generic strategy to maintain/inject variables per environment for any microservice. Currently all variables are getting stored either into a common ADO library (variable group per environment) or a microservice specific ADO library (variable group per microservice). Here we do not have tracking for variables. Current approach is good for few services (10-15) but problematic for more services (20-100) in future.
Example: Schema service needs to have some variables which varies per environment. Now that can only be stored into common ADO library. This suffice the current need but common ADO library is growing up at scale and ends up with maintaining huge number of variables which would be difficult to maintain and track with the growth in number of microservices.
