Use Things you Understand! Learn the fundamentals to understand the layers of abstraction! And remember 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 "Designing and Architecting for ..read more

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 arch ..read more

Whether its GitOps, DevOps, Platform Engineering, Observability as a Service or other terms. We all have our definitions, but rarely do we have a consensus on what those terms really mean! To get some clarity we invited Roberth Strand, CNCF Ambassador and Azure MVP, who has been passionately 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, wh ..read more

Can you explain GitOps in simple terms? 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 ses ..read more

While the mainframe is powering the world's most critical system the words "modern", "open source" or "generative AI" typically don't come to mind. So lets change this! To do that simply tune in to our latest episode where we have Jessielaine (Jelly) Punongbayan, Sr. Technical Support Engineer at Dynatrace, telling us why she is excited about the modern Mainframe and how it brought her from the Philippines via Singapore and Czech Republic to Austria. We learn about all the open-source projects and communities she is involved in such as Open Mainframe or Zowe that make it easy to connect the M ..read more

201 is the HTTP status code for Resource Created. It is also the number of PurePerformance Episodes (including this one) we have published over the past years. None better to invite than the person who initially inspired us to launch PurePerformance: Mark Tomlinson, Performacologist and Director of Observability at FreedomPay Tune in and listen to our thoughts on current state of automation, a recap on IFTTT, whether we believe that AIs such as CoPilot will not only make us more efficient in creating code and scripts but also lead to new ways of automation. We also give a heads-up (or rather a ..read more

Marcelo Amaral is a Researcher for Cloud System Optimization and Sustainability. With his background in performance engineering where he optimized microservice workloads in containerized environments making the leap towards analyzing and optimizing energy consumption was easy. Tune in to this episode and learn about how Kepler, the CNCF project Marcelo is working on, which provides metrics for workload energy consumption based on power models it was trained on by the community. Marcelo goes into details about how Kepler works and also provides practical advice for any developer to keep energy ..read more

4% of worldwide CO2 emissions come from IT and like in all other industries we have big potential to not only reduce the carbon footprint but also lower costs. Tune in to our episode where we have Mario-Leander Reimer, CTO at QAware GmbH, talk about his top 3 suggestions for Sustainable IT: Making the right architectural choices, Right-sizing your environments and shutting down environments not needed! Mario is also heavily involved in the CNCF and gives us an overview of projects to look into such as Kepler, kube-green, Karpenter or Carbon Aware Multi-Cluster Schedulers. Here are the links w ..read more

Martin Spier was one of six engineers to take care of all of Netflix Operations about 10 years ago. Back then performance and observability tools weren't as sophisticated and didn't scale to the needs of Netflix as some do today. FlameScope was one of the Open Source projects that evolved out of that period, visualizing Flame Graphs on a time-scaled heatmap to identify specific performance patterns that caused issues in their complex systems back then. Tune in to this episode and hear more performance and observability stories from Martin, about his early days in Brazil, his time at Expedia an ..read more

As far as we know - besides Kubernetes there is only Prometheus that belongs to the prestigious group of open-source projects that have their own documentary. Now why is that? Prometheus has emerged as the go-to solution for capturing metrics in modern software stacks, earning its status as the de facto standard. With its widespread adoption and a constantly expanding ecosystem of companion tools, Prometheus has become a pivotal component in the software development landscape. Join us as we sit down with Björn Rabenstein, an accomplished engineer at Grafana, who has dedicated nearly a decade t ..read more
