Build Stuff 2017

Financial systems for Institutional Investors and Wealth Management are among some of the most demanding software systems produced today, requiring great throughput, scale, and accuracy, along with stringent availability, audit, and recovery requirements.
We will discuss our ongoing transformation of a large Asset Management product line from multiple legacy N-Tier applications into a single flexible Vectored Event Driven Application Architecture that brings together CQRS/ES, DDD, Micro Services, SEDA, and Vector Clocks in a coherent and structured manner.
Using this architecture, we have been able to create a deterministic and provably correct distributed system that can be reasoned about easily, provides good NFRs, and in the event of partitions will provide stale rather than inconsistent data.
The talk will focus on the Architectural transformation and cover the reasons for adopting each of the core components. This will include details on the benefits, roles, and constraints for each component, along with the critical role each plays in the overall architecture, as well as the overall definition and structure.
