The company where I am working at currently is using Spring Boot/Cloud and we looking to break apart our monolith into microservices and implement auditing functionality. I can’t provide details about what we are doing but I am fairly convinced Lagom’s architecture fits our needs better than Spring Boot/Cloud and have a strong feeling we will end up spending a lot of time reimplementing what Lagom provides for free (primarily persisting of events and event driven architecture where microservices communicate using a message bus). Our CTO wants to see concrete evidence supporting this claim but it is very difficult to provide this.
I am not an expert on Lagom and was wondering if there were any objective reasons why Lagom is better that Spring for a event driven, event persisting microservices. Performance is not really a requirement, however development speed, reliability and robustness are.
