Joined a start-up working on a fantastic ‘Google Search for Cars’ application. Very new and exciting technology. Java/Groovy Vert.x based microservices running in Docker containers on AWS.

The microservices self-registered with Consul (Service Discovery) and clients to these microservices used Netflix Ribbon in conjunction with Hystrix to load balance the HTTP calls to the RESTful endpoints of the microservices and ‘circuit break’ on failure.

This provided us with a fast and highly scalable architecture which could be monitored constantly and would also self-heal.

I absolutely loved the technology we used here, the architecture was rock solid and they were all fantastic people to work with.

Also used some React to build a front end onto a statistics dashboard which queried a RESTful microservice connected to ElasticSearch as the persistent store.
