Hi,
Is there any good reading how application code should be patched in
relation to database migration?
The requirements are to maintain uninterrupted service for end users.
We're almost there with multi-zone configuration, haproxy loadbanacers.
But sometime application requires DB migration and it means app servers
should be shutdown. What design would you consider in this case?
Thanks,
