Green Software Architecture: A Bird's Eye View
This session will provide an overview of the state of the art in architecting for sustainability: rationale; integrating reduction and mitigation; design principles; existing frameworks; reference and evaluation models; tools, communities and APIs.
Modernizing Monoliths: principles, patterns, risks and roadmaps
The legacy monolith (AKA Big Ball of Mud) is a challenge to startups and even more to large and established companies, built when paradigms and tooling followed different patterns. As the tech ecosystem has evolved, new patterns, tools, APIs and possibilities tend to overtake them, tightly coupled apps become a source of increasing technical debt and diminishing competitiveness and business value. But the alternatives are fraught with risks, challenges and complications. I will review 6 state-of-the-art patterns: maintaining the legacy (Wikipedia); decomposing into a modular monolith (Etsy); decomposing into microservices (About You); Serverless monoliths (Phantom); Serverless microservices (Liberty Mutual), and microservices as a service (Moonpig/CommerceTools). In the process I will offer principles, roadmaps, risks and tools to make the jump, touching on the issue of language migration/complementation.
Advanced Technical Debt Management: The Good, The Bad And the Costly
A workshop training you in assessing, measuring, monitoring and transforming technical debt, evaluating its effects on operational security and environmental debt and its risk trajectory. This includes a green amber red model, from when technical debt is beneficial to when it's an emergency; metrics to judge the severity, including code analysis, issue analysis, version analysis, carbon footprint analysis, critical incident analysis and financial cost attribution. It will also cover how to integrate tech debt management into CI; how to prioritise what to refactor, alternative strategies for debt recovery, some relevant tooling, and how to make the business case for investment to management in a persuasive, non-technical way.
