Main benefit with microservices is independent deployments.

In my team, we once had 5 deployments of our service in a day and we did not have to coordinate it with anyone outside the team. This is an amazing benefit. Not many realise the cost we pay due to coordination. I can't even imagine how this would work in a monolith. Maybe we would meticulously write code in our dev environment and kinda pray that it works properly in production when our code is released say once a day.

Real life is more messy and it is great that I had the option to deploy 5 times to production. That fast feedback loop is much appreciated.
