Autoscaling in Production: When It Works and When It Doesn't with Zaigham Sarfaraz and Šimon Bučko

Sovereign Cloud and Sovereign AI in Europe with Klaus Koefoed, CEO of T-Systems

Klaus Koefoed spent more than 25 years in IT services and consultancy, at Capgemini, Deloitte, and Accenture, before taking over as CEO of T-Systems in Northern Europe. In this episode of the Smooth Scaling Podcast, Klaus walks host Jose Quaresma through the rise of sovereign cloud: why a theme almost nobody raised two years ago turned urgent in early 2025, and what actually changed. They get into Europe's real position against the American hyperscalers, why the answer is rarely either/or, and how leaders should weigh the data, operational, technology, and legal layers of sovereignty. Klaus is candid that none of this comes for free. Multi-cloud adds complexity, and the right answer depends entirely on who you are. The back half turns to sovereign AI, where T-Systems and NVIDIA have stood up a billion-euro Industrial AI Cloud, and where Europe's gigafactory ambitions, real use cases like simulated wind tunnels, and AI Scrum Teams come in. A grounded, practical look at building and running infrastructure when geopolitics is suddenly part of the architecture.

Klaus Koefoed is CEO of T-Systems Northern Europe, leading Deutsche Telekom's B2B IT-service business across the Nordics, UK and Ireland. He joined T-Systems in June 2023 from Capgemini, where he was VP and Nordic Head of Cloud Strategy & Transformation Advisory. Before that, he was a Partner at Deloitte Consulting, with earlier years at Accenture. Copenhagen-based, with 25+ years in IT services and consultancy. His move from advising to operating arrived just as digital sovereignty stopped being a compliance footnote and became a board-level resilience question. Under Klaus, T-Systems Northern Europe has pushed hard on Sovereign Solutions for Europe and especially T Cloud Public (formerly known as Open Telekom Cloud) — now ten years old enterprise grade European Public Cloud — and recently opened the Industrial AI Cloud, Europe's largest sovereign AI-infrastructure, with 10,000 GPUs connected to the existing portfolio. That makes him one of very few executives in the region who can credibly talk about running sovereign cloud and sovereign AI at scale in Europe.  🔗 Connect  Klaus Koefoed: https://www.linkedin.com/in/klauskoefoed/  Host José Quaresma: https://www.linkedin.com/in/jose-quaresma/  This podcast is researched by Joseph Thwaites, produced by Perseu Mandillo, and brought to you by Queue-it, your virtual waiting room partner.  © Queue-it, 2026

The Rise of Cloud Prem: Data Ownership in the Age of AI with Galileo's Sam Dhar

Sam Dhar has spent 14 years building infrastructure at Cisco, Amazon Alexa, and Adobe, and now works as Senior Staff Engineer and AI infrastructure leader at Galileo, the enterprise AI evaluation platform. In this episode of the Smooth Scaling Podcast, Sam walks host Jose Quaresma through Cloud Prem: deploying your full product stack inside the customer's own cloud environment instead of running it as SaaS. They get into why the model is resurging, and it mostly comes down to data. Enterprises want ownership and control, plus a heavy compliance load (SOC 2, HIPAA, fully air-gapped government workloads), and they do not want a vendor sitting in the read path of their most sensitive data. Sam is candid about the hard parts. Cloud Prem can be a losing game on margins, deployment is the slowest thing in the pipeline, and every customer environment is different enough to reset the work. The conversation closes on AI: why it makes Cloud Prem urgent, the brutal GPU shortage, and why self-hosting an Opus-class model is still out of reach for most companies. A direct, practitioner-level look at where enterprise AI infrastructure is actually heading.

A Decade of Kubernetes Lessons with Chris Nesbitt-Smith

Chris Nesbitt-Smith has been running Kubernetes in production since version 0.4 — long before pods, before managed services, before most of today's tooling existed. In this episode of Smooth Scaling, he sits down with José Quaresma to share what a decade of running Kubernetes for UK government citizen-facing services has taught him about scaling critical infrastructure. The conversation covers why Kubernetes was the least bad option (and largely still is), why relying on autoscaling means you've already lost, and how Gregor Hohpe's "guardrails versus lane assist" metaphor changes the way you think about capacity. Chris makes the case for climbing the service stack — SaaS first, then Functions as a Service, then Platform as a Service, and only reluctantly managed Kubernetes — and explains why tech is one of the only industries that builds critical systems without ever pricing the risk of failure. A direct, opinionated look at what scaling really demands when the stakes are real and the budget isn't infinite.

Autoscaling in Production: When It Works and When It Doesn't with Zaigham Sarfaraz and Šimon Bučko

In this episode, José Quaresma sits down with two Queue-it engineers — Zaigham Sarfaraz, Engineering Manager, and Šimon Bučko, Senior Software Engineer — to talk autoscaling in production. They cover the fundamentals of horizontal and vertical scaling, why stateless architecture matters for scaling out, and what happens when the metrics you're scaling on don't match your actual bottleneck. The conversation gets real when Zaigham shares a war story of autoscaling failing during an iPhone launch — one million users in one second — and how that experience reshaped how the team thinks about pre-scaling for extreme traffic. Šimon challenges the temptation to rely on default configurations and explains why the days you most need autoscaling to work are exactly the days it might not.

Observability as a Product: Building Platforms Engineers Actually Use with Iris Dyrmishi

In this episode, José Quaresma speaks with Iris Dyrmishi, Senior Observability Engineer at Miro, about building an observability platform that hundreds of engineers actually trust and use. Iris explains how her team treats observability as an internal product, walks through Miro's tracing migration from Jaeger and Zipkin to OpenTelemetry with zero disruption, and shares how teams now use traces proactively to find bottlenecks before they become outages. The conversation also covers the honest downsides — alert noise, dashboard sprawl, and the cost of observability — including a recent example using eBPF and Grafana Beyla to uncover hidden networking expenses that transformed Miro's cloud bill.

She started as a backend engineer before moving into SRE roles at Worten Portugal and Farfetch, where she developed her specialty in tracing and drove OpenTelemetry migrations across large engineering organisations without disrupting existing workflows. A CNCF Ambassador, co-organiser of Kubernetes Community Days Porto, and active voice in the observability community, she writes extensively about practical adoption challenges and has spoken at KubeCon EU and on the o11ycast podcast. Her guiding philosophy: observability is a team sport. This podcast is hosted by José Quaresma, researched by Joseph Thwaites and produced by Perseu Mandillo.  © Queue-it, 2026
