Domain-Driven Serverless Design
I love mashing up ideas and seeing what happens. Two areas of deep interest for me over the last two years have been Domain-Driven Design (DDD) and Serverless infrastructure (also known as Functions as a Service). What do these two areas have in common? The central concept of events, of course!
Domain-Driven Design helps us to identify Aggregates, or clusters of objects, that maintain both business invariants and transactional boundaries for one or more domain concepts. These Aggregates communicate with other Aggregates through the use of Domain Events, which potentially trigger other behaviors. We can chain these behaviors to create eventually consistent, long-running business processes.
Serverless infrastructure, at least as its currently been expressed in offerings like AWS Lambda and Azure Functions, has also focused on events as the sole mechanism available for triggering the execution of standalone functions. For one function to trigger another function, it must produce an event that is then consumed by the downstream function’s trigger. We can achieve this through the use of queuing mechanisms, data stores, and even HTTP gateways.
In this session, we’ll explore a mashup of DDD and Serverless infrastructure, and examine how these two areas can synergize to create evolvable and scalable systems.
About Matt Stine
My passion is taking a metaphysical approach to software engineering: what is the nature of the collaborative game that we continuously play, and are there better, more contextually-aware ways to play that game?
By day I lead a team tasked with taking a first-principles-centric approach to intentionally enabling programming language usage at the largest bank in the United States.
By night I write and teach my way through a masterclass in software engineering and architecture targeting early-career software engineers working in large-scale enterprise technology organizations.
What is the primary goal?
To win the game. More seriously: to get 1% better every day at providing business value through software.
Who am I?
I'm a 22-year veteran of the enterprise software industry. I've played almost every role I can imagine:
- Software Engineer
- Software Architect
- Technical Lead
- Engineering Manager
- Consultant
- Product Manager
- Field CTO
- Developer Advocate
- Conference Speaker
- Author
- Technical Trainer
- Technical Marketer
- Site Reliability Engineer
- Desktop Support Specialist
I've worked at Fortune 500 companies, a tenacious teal cloud startup, and a not-for-profit children's hospital. I've written a book, and I've hosted a podcast. I've learned a lot along the way, including many things I wish I'd known when I first got started. And so now I want to pass those learnings on to you, especially if you've only just begun your career.
