In this episode, Jon sits down with Jacek Marmuszewski, founder of Let’s Go DevOps, to explore the evolution of DevOps from its chaotic early days to today’s specialized platform engineering landscape. Broadcasting from Krakow, Poland’s thriving tech hub, Jacek shares his 15+ year journey from Java developer to building a 20+ person DevOps consultancy that addresses some of the most complex infrastructure challenges in the industry.From creating AWS’s first-of-its-kind “ultra cluster” with 8TB of unified memory to inadvertently shutting down an entire European country’s internet while migrating half a petabyte of data, this conversation is filled with war stories, technical insights, and practical advice for modern DevOps challenges.Key TakeawaysDevOps Evolution: The field has shifted from “hire DevOps to fix everything” mentality to specialized platform engineering roles focused on creating developer highways for faster software deliveryMulti-Cloud Reality Check: True multi-cloud implementations often create more pain than benefits – most companies should focus deeply on one primary cloud provider rather than spreading thin across multiple platformsSecurity-First Approach: Implementing “shift-left” security by embedding scanning tools, least-privilege access, and compliance restrictions directly into reusable platform modulesSpecialization Over Generalization: Rather than trying to solve every problem, focusing on deep expertise in specific areas (AWS/GCP, Linux, cloud-native) delivers higher quality resultsContinuous Learning Culture: Building teams where knowledge sharing and experimentation are encouraged through regular show-and-tell sessions and competitive security testingScale Challenges: Moving from startup “Swiss Army knife” DevOps to an enterprise-scale platform teams requires careful evolution of both technical approach and team structureYouTube Timeline00:00 Introduction – From Krakow to the Cloud00:32 Jacek’s 15+ Year DevOps Journey01:33 How DevOps Has Changed Over the Years02:55 What’s Missing from Today’s DevOps04:40 Introducing Let’s Go DevOps – The Team Approach07:11 Specialization vs. Swiss Army Knife Consulting08:09 Biggest Technical Challenges – The “Ultra Cluster” Project09:58 Krakow’s Tech Ecosystem Impact11:09 Multi-Cloud Strategy and Reality Check13:48 Security-First DevOps Implementation15:14 Shifting Security Left in Development17:38 Vision for the Future of DevOps19:17 Staying Ahead of the Technology Curve20:18 Achievement Showcase – AWS Ultra Cluster21:12 The “Hot Potato” Project – Half Petabyte Data Migration22:09 When DevOps Accidentally Shuts Down a Country’s Internet23:21 Wrap-up and Final Thoughts🔔 Don’t forget to Like, Subscribe, and hit the notification 🔔 ✔ Subscribe: https://www.youtube.com/jonmyer/?sub_confirmation=1📱 Social Media Twitter: https://twitter.com/_JonMyerWebsite: https://jonmyer.comLinkedIN: https://www.linkedin.com/in/jon-myer/Spotify: https://open.spotify.com/show/0wjJzdIwctq4o4pTXM2KSFLike my sounds?
