Has one of the decision makers in your organization decided that you have to go "all in on technology X" because they saw a great presentation at a conference or got a great sales pitch from a vendor? If that is the case then this episode is for you and you should forward it to those decision makers. Sebastian Vietz, Director of Reliability Engineering and Host of the Reliability Enablers Podcast, shares his thoughts on considerations when picking a technology like Serverless. We discuss the importance of knowing limits, best fit architectural patterns and things that should influence your technology decisions! Being aware of coldstarts, a 20000 concurrent request limit or 512mb being an ideal size for Lambda are just some of the things we can all learn from Sebastian.

When thousands of systems show a blue screen - which ones do you fix first to quickly bring up your most critical systems? For that you need to know which systems are impacted, which mission critical applications run on it, and which depending systems are also impacted by something like the recent CrowdStrike incident! We have invited Josh Wood, Principal Solutions Engineer at Dynatrace, who was one of the first responders helping organizations to leverage observability data to identify which systems to fix first to bring critical apps such as ATMs, Self-Service Terminals, POS (Point of Sales), ... back up again quickly. In this special episode Josh is walking us through the technical details of the CrowdStrike BSOD (Blue Screen of Death), what caused it, how to leverage observability to get a priorities list of systems to fix first and what organizations can do to prevent software impacting issues in the future.

WebAssembly runs in every browser, provides secure and fast code execution from any language, runs across multiple platforms and has a very small binary footprint. It's adopted by several of the big web-based SaaS solutions we use on a daily basis.  But where did WebAssembly come from? What problems does it try to solve? Has it reached critical adoption? And how about observing code that gets executed in browsers, servers or embedded devices? To answer all those questions we invited Matt Butcher, CEO at Fermyon, who explains the history, current implementation status, limitations and opportunities that WebAssembly provides.

Use Things you Understand! Learn the fundamentals to understand the layers of abstraction! And that we don't live in a world with unlimited resources! These are advice from our recent conversation with Ernst Ambichl, Chief Product Architect at Dynatrace, who has started his performance career in the late 80s building the first load testing tools for databases which later became one of the most successful performance engineering tools in the market. Tune in and learn about how Ernst has evolved from being a performance engineer to become an advocate for "Deg and Architecting for Performance". Ernst explains how important good upfront analysis of performance requirements and characteristics of the underlying infrastructure is, how to define baselines and constantly evaluate your changes against your goals. On a personal note: I want to say THANK YOU Ernst for being one of my personal mentors over the past 20+ years. You inspired me with your ion about performance and building resilient systems

SREs (Site Reliability Engineers) have varying roles across different organizations: From Codifying your Infrastructure, handling high priority incidents, automating resiliency, ensuring proper observability, defining SLOs or getting rid of alert fatigue. What an SRE team must not be is a SWAT team - or - as Dana Harrison, Staff SRE at Telus puts it: "You don't want to be the fire brigade along the DevOps Infinity Loop" In his years of experience as an SRE Dana also used to run 1 week boot camps for developers to educate them on making apps observable, proper logging, resiliency architecture patterns, defining good SLIs & SLOs. He talked about the 3 things that are the foundation of a good SRE: understand the app, understand the current state and make sure you know when your systems are down before your customers tell you so! If you are interested in seeing Dana and his colleagues from Telus talk about their observability and SRE journey then check out the On-Demand session from Dynatrace Perform 2024: https://www.dynatrace.com/perform/on-demand/perform-2024/?session=simplifying-observability-automations-and-insights-with-dynatrace#sessions

Whether its GitOps, DevOps, Platform Engineering, Observability as a Service or other . We all have our definitions, but rarely do we have a consensus on what those really mean! To get some clarity we invited Roberth Strand, CNCF Ambassador and Azure MVP, who has been ionately advocating for GitOps as it was initially defined and explained by Alexis Richardson, Weaveworks in his blog What is GitOps Really! Tune in and learn about Desired State Management, Continuous Pull vs Pushing from Pipelines, how Progressive Delivery or Auto-Scaling fits into declaring everything in Git, what OpenGItOps is and why this podcast will help you get your GitOps certification (coming soon) As we had a lot to talk we also touched on Platform Engineering and various other topics Here are all the links we discussed: Alexis GitOps Blog Post: https://medium.com/weaveworks/what-is-gitops-really-e77329f23416 OpenGitOps: https://opengitops.dev/ Flux Image Reflector: https://fluxcd.io/flux/components/image/ CNCF White Paper on Platform Engineering: https://tag-app-delivery.cncf.io/whitepapers/platforms/ Platform Engineering Maturity Model: https://tag-app-delivery.cncf.io/whitepapers/platform-eng-maturity-model/ Platform Engineering Working Group as part of TAG App Delivery: https://tag-app-delivery.cncf.io/wgs/platforms/

Can you explain GitOps in simple ? How does it fit into Continuous Integration (CI), Continuous Delivery and Continuous Deployment? And what are considerations when rolling out GitOps in an enterprise? To get answers to those questions we sat down with Christian Hernandez, Head of Community at Akuity, who has a fabulous analogy to explain GitOps that I am sure many of us will "borrow" from him. Christian also explains the ecosystem he works in such as ArgoCD, Kargo as well as OpenGitOps which aims to provide open-source standard and best practices to implementing GitOps. We closed the session with some advice around Application Dependency Management, External Secrets Operator and choosing the right Git Repo Structure.

Its only been a year since ChatGPT was introduced. Since then we see LLMs (Large Language Models) and Generative AIs being integrated into every days life software applications. Developers have the hard choice to pick the right model for their use case to produce the quality of output their end s demand. Tune in to this session where we have Nir Gazit, CEO and Co-founder of Traceloop, educating us about how to observe and quantify the quality of LLMs. Besides performance and costs engineers need to look into quality attributes such as accuracy, readability or grammatical correctness. Nir introduces us to OpenLLMetry - a set of Open Source extensions built on top of OpenTelemetry providing automated observability into the usage of LLMs for developers to better understand how to optimize the usage of LLMs. His advice to every developer is to start measuring the quality of your LLMs on Day 1 and continuously evaluate as you change your model, the prompt and the way you interact with your LLM stack! If you have more questions about LLM Observability check out the following links: OpenLLMetry GitHub Page: https://github.com/traceloop/openllmetry Traceloop Website: https://www.traceloop.com/ OpenLLMetry Documentation: https://traceloop.com/docs/openllmetry

After analyzing Distributed Traces over more than 15 years Brian and I thought that everyone in software engineering and operations must be satisfied with all that observability data we have available. But. Maybe Brian and I were wrong because we didn’t fully understand all the use cases - especially those for developers that must fix code in production or need to quickly understand what code from somebody else is really doing without having the luxury to add another log line and redeploy on the fly. To learn more about the observability requirements of developers we invited Liram Haimovitch, CTO at Rookout and now part of Dynatrace, who has spent the last 7 years solving the challenging problems that developers face day and night. Tune in and learn about what non-breaking breakpoints are, how it is possible to "debug in production" without impacting running code and how we can make developers lives easier even though we push so many things "to the left"

I was invited to speak at BankTechShow in Budapest, Hungary where the nations IT leaders in the banking sector presented and discussed the future of banking - both in the cloud as well as what it means for the physical bank branches. I got a chance to sit down with Adam Gajdi, IT Solutions CoE Lead at K&H, who walked me through the process of their recent new mobile banking app launch. Adam highlighted the importance of observability for both business owners as well as developers. Furthermore, Adam enlightened me with the fact that Hungarian banks are mandated to conduct chaos tests to proof that their systems are resilient in case of data center outages. I was obviously also curious about how AI, LLMs and other technologies are adopted in their sector. Tune in to learn more
