S3E4: Sarah Wells
Shownotes
Sarah Wells joins Nick and Chris to talk about the lessons learned from her decade at the Financial Times, and their journey to implementing microservices. The same lessons that informed her book, 'Enabling Microservices Success'. We touch on whether the purpose of microservices is to scale a system, or to scale an engineering organisation. By breaking down monoliths into independent domains, teams can reduce cognitive complexity and release software hundreds of times a day. Sarah warns however that this shift introduces a "maintenance treadmill", requiring robust automation for library upgrades, security patching, and cross-service governance to prevent a sprawl of unmanageable tech debt.
The conversation goes deep on human factors, and the role of organizational culture in technical success. Sarah emphasises the importance of a 'generative culture', as defined by Ron Westrum, where information is shared openly. By taking a 'you build it, you run it' approach supported by a strong platform team, organizations can balance individual team autonomy with the necessary guardrails for long-term operational health and efficiency.
