Raising the Bar on Resilience: Designing Systems for Resilience at Scale Using Feature Flags

Recent years have demonstrated that the scale required of our systems is anything but predictable. Moreover, when systems become overwhelmed they often fail spectacularly rather than discreetly. Unlike our need for scale, failure is predictable, and with proper design and tooling, blast radius can be contained and isolated. Isolating failure requires deliberate design, understanding of failure modes and how to compensate and contain them. Designing for failure doesn’t have to come at the expense of delivery velocity. With the right tools and tactics you can raise the bar on the resilience of your systems. In this session, Alex will lay out practices and tools to help you optimize the resilience of your systems. From containing security events to adapting to changes in scale, you will walk away with the insights you need to improve the resilience of your legacy and brownfields and greenfields alike.

Building Better Software: Lessons from Construction

Monday Mar 27 / 02:55PM BST

Software development and construction may seem like completely different worlds, and yet we use similar terminology to describe concepts in both: infrastructure, architects, frameworks, scaffolding, foundations, builds, … Are these two processes really so similar?
