The writing is on the wall. Traditional services just won't cut it for mobile and IoT. Who is willing to wait for 2-3 seconds for each service call to respond and be parsed per mobile event. I think this is also driven by SPA style programming where micro data segments need to be served almost at realtime vs. loading the entire service data. Microservices are the clear winner
Question is what is the migration path for enterprises from SOA to Microservices? And how much heavy lifting in terms of rewrite is needed.
