Monolithic Grails app
Everything works fine. Until...
Changes in one module breaks other modules
Cannot scale up only part of the application
High risk adopting new technologies
Test, build and deploy jobs take forever
Hard to establish ownership and autonomous teams
Introducing microservice
Benefits
Cleaner boundry between services
Can scale up services independently
Services can be implemented with different tech stack
Smaller code base, faster to build and deploy
Flexible release schedule
Enable autonomous teams
No silver bullet
Things to watch for
Ops overhead (config, deploy, monitor, logging, etc.)
Transaction management
Fault tolerant
Testing
