To provide zero downtime upgrades of my highload service I use blue green deployment strategy.

Every moment data changing happens, so how to migrate all data consistently? In the moment I switch between blue and green the data is changing.

What is the best strategy to maintain data consistency (as much as possible)?

    This question is quite vague. Usually the solution to this is to blue-green stateless resources and have shared, separate state. – Ant P May 02 '19 at 13:47
  • Does it mean blue-green strategy is not appropriate for this case? – J.J. Beam May 02 '19 at 15:54
