The ThoughtWorks Technology Radar is full of good stuff. Here are my personal favorites:
There's an upfront cost in building more distributed systems with independently operated micro services but it brings so much clarity to your world. You can align small agile teams with each service, you have much more explicit conctracts, leaky interfaces becomes more rare.
The key trend here is that platform services and frameworks have come a long way to make it easier to build micro services. So you should absolutely trial it out and understand just how the cost compares to your current approach.
