Experience

Microservice Architecture for Customer Interaction Analytics

In the pursuit of migrating a large interaction analytics platform from the massive servers of a data center to a nimble swarm of EC2 instances, we needed to rebuild our application as a group of microservices.

Each service was extracted from the functional definition of our software, and over several months, we reached feature parity with the original monolithic system. Using load balancers and auto-scaling rules, the data processing nodes were able to rise to meet large batch processing dumps and scale back down during periods of relative quiet.
