From one side, it makes it easier to monitor and update / rollback systems that lowers performance-related risks. The answer to this challenge is service virtualization, which allows simulating real services during testing without actual access. The dynamic architectures represent a major challenge for both monitoring and analysis.

If tuned for performance, there is a good change reliability is compromised - and vice versa. This means despite having extensive observability and monitoring we cannot detect new problems or issues unless we go through them. Generally speaking, data pipelines are leaky by nature. Pipeline reliability and performance go hand in hand.

If you are mostly virtualized on machines with 8 or fewer logical processors with a default MAXDOP, you're probably in OK.

If you have big physical hardware with defaults, then you should look at optimizing MAXDOP.
