One PetaByte is the equivalent of 11000 4k movies. And CERN's Large Hadron Collider (LHC) generates this every single second. Only a fraction of this data (~1 GB/s) is stored and analyzed using a multicluster batch job dispatcher with Kueue running on Kubernetes. 
In this episode we have Ricardo Rocha, Platform Engineering Lead at CERN and CNCF Advocate, explaining why after 20 years at CERN he is still excited about the work he and his colleagues at CERN are doing. To kick things off we learn about the impact that the CNCF has on the scientific community, how to best balance an implementation of that scale between "easy of use" vs "optimized for throughput". Tune in and learn about custom hardware being built 20 years ago and how the advent of the latest chip generation has impacted the evolution of data scientists around the globe

The word "Compliance" reminds many about mandatory training or audits. Two things not everyone gets excited about!
Tune in and meet Michiel de Lepper who has spent most of his career in Security and Compliance. He gives us a different perspective on the importance of compliance, why it exists, how it intertwines with security and threat detection, what it has to do with security posture management and why he thinks its one of the most exciting things in IT!

Feature Flagging - some may call them "glorified if-statements" - has been a development practice for decades. But have we reached a stage where organizations are doing "Feature Flag-Driven Development?". After all it took years to establish a test-driven development culture despite having great tools and frameworks available!
To learn more we invited Ben Rometsch, Co-Founder of Flagsmith, to chat about the history, state and future of Feature Flagging. He is giving us an update on where the market is heading, how the CNCF project OpenFeature and its community is driving best practices, what the role of AI might be and what he thinks might be next!

To predict the future, it's important to know the past. And that is true for Bernd Greifeneder, Founder and CTO of Dynatrace, who has been driving innovation in the observability and security since he founded Dynatrace 20 years ago!

Bernd agreed to sit down, look behind the covers and answer the open questions that people posted on his LinkedIn in response to his recent observability prediction blog. 
Tune in and learn about Bernd's though on the evaluation from reactive to preventive operations, who is behind the convergence of observability & security, why observability can help those that have serious intentions for sustainability and how observability becomes mandatory and indispensable for AI-driven services.

eBay, Yahoo, Netflix and then 10+ years at Uber. In this episode we sit down with Vishnu Acharya, Head of Network Infrastructure EMEA and Platform Engineering at Uber. Vishnu shares how Uber has scaled over the years to about 4000 engineers and how his team makes sure that infrastructure and platform engineering scales with the growing company and the growing demand on their digital services.
Tune in and learn about how Vishnu thinks about SLOs across all layers of the stack, how they manage to get better insights with their cloud providers and why its important to have an end-to-end understanding of the most critical end user journeys.

For the past 10 years Anton has been working at Booking.com - one of the leading digital travel companies based out of Amsterdam. The journey that started as System Administrator has led Anton to be an Engineering Manager for Site Reliability where over the past 3 years he led the rollout and adoption of OpenTelemetry as the standard for getting observability into new cloud native deployments.
Tune in and learn how Anton saw R&D grow from 300 to 2000, why they replaced their home-grown Perl-based Observability Framework with OpenTelemetry, how they tackle adoption challenges and how they extend and contribute back to the open source community

Most services are moving to SaaS - whether it’s email, collaboration, customer relations, or finance. But not everyone can go to SaaS - or at least that’s the initial reaction when navigating certain industries’ rules and regulations.
Milan Steskal - who worked in healthcare for many years - is now helping organizations ask the right questions and find the best solutions as they evaluate their options to move their observability data to SaaS. Tune in and learn about the questions to ask vendors and your internal security, privacy, and compliance teams. Milan also walks us through the capabilities SaaS vendors such as Dynatrace have put in place to protect data sent to the cloud so that it stays safe and only accessible to those needing access.

Andreas Taranetz is a software engineer and lecturer at the University of Vienna. He creates a lot of educational content around Web Performance Optimization. For the past seven years, he has also operated Wahlkabine, Austria's top website, for matching one's political views with the parties that are up for election.
This episode was an amazing flashback - reminding us about the time when Steve Souders - the "godfather" of Web Performance Optimization - educated web developers about optimizing CSS, JavaScript, and server-side roundtrips.
Tune in and learn why Web Performance is still such an important topic, how it relates to sustainability, why you should cache on every layer, and what the Static Site Paradox really is!

Authentication (validating who you claim to be) and Authorization (enforcing what you are allowed to do) are critical in modern software development. While authentication seems to be a solved problem, modern software development faces many challenges with secure, fast, and resilient authorization mechanisms. 
To learn more about those challenges, we invited Alex Olivier, Co-Founder and CPO at Cerbos, an Open Source Scalable Authorization Solution. Alex shared insights on attribute-based vs. role-based access Control, the difference between stateful and stateless authorization implementations, why Broken Access Control is in the OWASP Top 10 Security Vulnerabilities, and how to observe the authorization solution for performance, security, and auditing purposes.
