Cloud Native Testing Podcast

In this episode of the Cloud Native Testing Podcast, Ole Lensmar sits down with Benjamin Wilms, founder and CEO of Steadybit, to explore the role of chaos engineering in building resilient cloud-native systems—from early-stage startups to global enterprises.

Benjamin shares how his journey from consulting to founding Steadybit was shaped by one key lesson: the best learning happens when systems fail. He explains how chaos engineering can shift from a manual, reactive effort to a repeatable practice that empowers teams to uncover weaknesses before they cause real-world outages.

They also dig into the cultural side of resilience engineering—how game days can bring teams together, why you don’t need massive scale to get started, and what it takes to build an organization where failure leads to progress, not blame.

In this episode of the Cloud Native Testing Podcast, Ole Lensmar sits down with Tony Tam, creator of Swagger API (now known as the OpenAPI specification) and a pioneer in API specification standards, to explore the unexpected ways Swagger transformed software testing.

Tony shares the origin story of Swagger: from its roots in solving REST client generation to how it became a foundational tool for testing, documentation, and collaboration across teams. He explains how OpenAPI specs gave rise to a new generation of spec-driven testing, enabling everything from automated validation to smarter negative test cases.

Whether you're maintaining legacy services, scaling microservices, or figuring out how to test AI-powered workloads in distributed environments, Tony’s insights into API resilience, tooling, and testing culture are not to be missed.

In this episode of the Cloud Native Testing Podcast, Ole Lensmar sits down with In this episode of the Cloud Native Testing Podcast, Ole Lensmar sits down with Cherif Sahraoui, QA Lead & Consultant working with 50Hertz Transmission—one of Germany’s four major electricity transmission system operators, responsible for delivering power across northern and eastern Germany—to explore the complexities of testing cloud-native applications in highly regulated industries like energy.

Cherif shares how his team manages application testing across both cloud and on-prem environments, why manual and exploratory testing still play a crucial role, and how tools like Testkube, Terraform, and ArgoCD help automate quality at scale.

They also dig into the cultural side of QA: how to foster shared responsibility for testing across dev and QA teams and why testing in production doesn’t deserve its bad reputation.

If you’re working in a regulated space or looking to improve your cloud-native testing strategy, this conversation offers practical takeaways you can apply right away.

In this episode of the Cloud Native Testing Podcast, Ole Lensmar sits down with Joe Karlsson, Developer Advocate at CloudQuery, to discuss how testing and governance intersect in today’s fast-moving cloud-native environments. They explore what it takes to catch issues like cloud drift, overly permissive configurations, and deprecated services—before they become costly outages.

Joe shares real-world insights from his work helping teams bake governance into CI/CD pipelines without slowing down delivery. From debugging GitHub Actions to building a culture of shared responsibility, this episode is packed with practical advice on making governance feel less like red tape—and more like a safety net for scaling teams.

In this episode of the Cloud Native Testing Podcast, Ole Lensmar sits down with Daniel Bryant, Engineer, Speaker, and Head of Product Marketing at Syntasso, to explore how testing is evolving in modern cloud-native environments. They dive into the critical role platform engineering plays in shaping a healthy testing culture, and how teams can strike the right balance between enforcing standards and empowering developers.

Daniel shares hard-won insights on testing in production, infrastructure validation, and why contract testing is essential when working with external dependencies. From technical best practices to organizational mindset shifts, this episode unpacks what it really takes to make testing a first-class citizen in the cloud-native world.

In this episode, Ole Lensmar talks with Joe Karp, DevOps Architect at UWM, about what it really takes to build a testing culture inside a modern, cloud-native organization. Joe shares how his team intentionally designed clear ownership between developers, QA engineers, and platform teams—and why empowering devs to own their testing is key to scaling quality across hundreds of services.

From infrastructure-level chaos testing to critical-path monitoring in production, Joe walks through the tooling, strategies, and cultural shifts that enabled UWM to test across multi-cloud, multi-cluster environments. They discuss why off-the-shelf tools often fall short, how internal platforms should be treated like products, and what it means to build resilience into both systems and teams.
