Explore DDD 2019 – Denver, Sept. 16-20
Say on Black Friday, a customer buys a pair of pants from a global retailer. This single purchase triggers a series of workflows across the enterprise: the JavaScript UI makes a dozen requests to a custom storefront backend, which in turn makes requests to the COTS inventory system, the third-party payment processor, myriad services for sales analytics, logistics, recommendations engines, and more. Each of these systems emits dozens, even hundreds, of discrete events, aggregated custom metrics, stack traces, and JVM telemetry data. Now multiply that times hundreds or thousands of concurrent purchases. Multiply that times the thousands of large retailers that rely on a multi-tenant SaaS platform to provide their observability services. This is the world Daniel walked into.
This talk follows the journey of an experienced software developer and DDD advocate in a world of high throughput, high availability data engineering. Daniel discusses the points where domain-centricity provides insight into this new domain, and where he’s finding dissonance. Building off a foundation provided by Nick Tune's 2018 Strategic Autonomous Design session, Daniel talks about what patterns and heuristics seem to be working, which are not, and what he’s learned on the way.
