 Several presentations about sustainability and how we can architect for a greener future, maybe it will become an entire track next year.
 What we can sum up is that we have the power to act at our own level. Choose services that auto-scale, prefer ARM instances, select partners who measure and try to improve their Carbon emissions. In many cases, Serverless or Compute@Edge can be a very good choice for applications that can take huge load spikes as much as a few requests (quickly scalable and extremely elastic). When possible, try to run jobs during the night, when load spikes are over. 
 The aim is to use energy when it is really needed: switching off dev and staging environments when employees are resting. Limit over-provisioning of resources and pre-scaling times.

 The last day of the conference offered a dedicated track on platform engineering, where we listened to the insights shared by the speakers. As they delved into their own experiences and learnings, we found striking parallels with our own journey at Bedrock over the past few years.

 One of the most resonant themes was the importance of treating the platform as a product—a perspective shift that has significantly influenced our approach. By emphasising the need for a smoother experience that balances consistency, performance, security, and development speed, the speakers reinforced the notion that our platform isn't just a set of tools; it's a crucial enabler for our developers' success.
 
 The concept of providing a golden path for developers stood out as particularly impactful. We've come to realise that by streamlining the onboarding process and offering clear guidelines, we can empower developers to navigate the platform with confidence and efficiency. This approach not only accelerates time-to-market for new features but also fosters a sense of trust between the platform team and its users.
