My two cents would be that tooling makes all the difference with microservices, especially in terms of developer productivity. Having tooling which allows me to test changes to a microservice locally and easily is a huge win, and without that tooling microservice development becomes much more difficult. Making it easy to test a service locally -- including its network interactions -- lets me be more confident that my code will work in production and reduces a lot of the cognitive overhead of developing one component among thousands.
