Greetings, Future Tech Titans! 👋

The AI revolution might be redefining business, but let me take you behind the scenes of another quiet revolution happening in our cloud stack—one that’s transforming how we deliver performance, resilience, and simplicity at scale.

In this edition of Tiny Big Spark, I’m diving into the massive impact of a focused decision: our move from Ceph to Pure Storage ActiveCluster in our 40,000-core Canonical OpenStack cloud. It’s a change rooted in deep customer insights, proven in rigorous testing, and aligned with our vision of performance-first infrastructure.

Here's what I’m sharing in this issue:

🔍 Listening to Latency: Why finance customers pushed us to rethink our storage layer.

⚙️ ActiveCluster in Action: The tech behind the switch—and what made it a game-changer.

🤖 Pure1 + Observability: How AI and metrics are simplifying our infrastructure management.

📊 From PoC to Production: The tests that sealed the deal (and the numbers that blew us away).

💬 My Take: What this shift means for our team, our users, and the future of OpenStack.

If you care about cloud performance, high availability, and engineering that just works—this one’s for you.

Stop Working for Loser Strategists

Roger encourages young professionals working with ineffective strategists to consider moving on after about two years, rather than staying in what he describes as a "kill zone." He believes that without a clear strategy, determining if decisions are beneficial or detrimental becomes nearly impossible until it's too late, turning work into a haphazard effort. While he suggests attempting to introduce your own strategy and possibly swaying your boss, Martin notes that remaining too long under inadequate strategic guidance can really eat into valuable career time.
