Micro services are all the rage. What makes this interesting is the swing from monolithic applications. This same pendulum swings in the operating system realm too; consider the microkernel.What will make the future of micro service is interesting is a complete set of micro services may end up looking something very similar to J2EE. In which case you might just implement in the j2ee framework and skip all the bugs and infrastructure development costs.On the other hand there are many good reasons for avoiding java in the first place.
