PurePerformance
The brutal truth about digital performance engineering and operations.Andreas (aka Andi) Grabner and Brian Wilson are veterans of the digital performance world. Combined they have seen too many applications not scaling and performing up to expectations. With more rapid deployment models made possible through continuous delivery and a mentality shift sparked by DevOps they feel it’s time to share their stories. In each episode, they and their guests discuss different topics concerning performance, ranging from common performance problems for specific technology platforms to best practices in development, testing, deploying and monitoring software performance and user experience. Be prepared to learn a lot about metrics.Andi & Brian both work at Dynatrace, where they get to witness more real world customer performance issues than they can TPS report at.

Self-Healing in the Real World – HATech Lessons learned from Enterprise Engagements
Self-Healing, Auto-Remediation: Magic words for most IT Leaders! When starting those kinds of projects teams realize their lack of maturity or even understanding of their current IT landscape to even think about Self-Healing. In other scenarios Self-Healing is misunderstood as a band-aid for “keeping the lights on” in order to buy more time for outstanding product improvements vs investing in the core architecture.In this podcast we invited Jon Hathaway, CEO of HATech, and Jarvis Mishler, Solutions Architect Team Lead at HATech (@hatechllc), to learn about how they help organizations assess and improve the maturity of their IT Systems & processes, which auto-remediation actions they typically implement and why real self-healing is not just about keeping the lights on!https://www.linkedin.com/in/jonhathaway/https://hatech.io/https://www.linkedin.com/in/jarvis-mishler/https://twitter.com/hatechllc

Let the Machines optimize the Machines: Goal-Driven Performance Tuning with Stefano Doni
Did you know that the JVM has 700+ configuration settings? Did you know that MongoDB performance can be improved by 50% just by tuning the right database and OS nobs? Every thought that slower I/O can actually speed up database transaction times?In this episode we invited Stefano Doni, CTO at Amakas.io, who gives us a new perspective on how to approach performance optimization for complex environments. Instead of manually tweaking nobs on all sorts of runtimes or services they developed a Goal-driven AI-engine that automatically identifies the optimal settings for any application as it is under load. Make sure to check out their website and white papers where they go into details about how their algorithms work, which metrics they optimize and how you can apply their technology into a continuous delivery processhttps://www.linkedin.com/in/stefanodoni/https://www.akamas.io/

Good Performance Engineers Look Behind the Percent Usage Metrics
Have you ever used USE? Have you ever wondered what differentiates a performance tester from a performance engineer? Want to know how to automate performance engineering into DevOps Pipelines?Twan Koot, Performance Engineer at Sogeti, is answering all these questions. We met him at the last Neotys PAC Event where he gave an in-depth look on metrics and enlightened us all with USE (a method from Netflix’s Brendan Gregg). In our conversation we explain what USE really is, how to apply it and how a good performance engineer needs to understand more than just response time!Links:Twan on linkedin - https://www.linkedin.com/in/twan-koot-a813a8b7/Twan's deck from Neotys PAC - https://www.neotys.com/performance-advisory-council/twan-kootTwans Video at Neotys PAC - https://www.youtube.com/watch?v=hV8wpkDUtyshttp://www.brendangregg.com/Brendan Gregg's home page - http://www.brendangregg.com/eBPF - https://prototype-kernel.readthedocs.io/en/latest/bpf/BCC - https://iovisor.github.io/bcc/

Keptn: Shipping and running cloud native apps with Alois Reitbauer
How many different continuous delivery pipelines do you have in your organization? Do you have dedicated teams that keep them up-to-date and constantly extend them with new tool integrations? Have you already built in capabilities for shadow, dark, blue/green or canary deployments? Is auto-mitigation and self-healing already on your internal pipeline roadmap? Sounds like a lot of manual work?Keptn (@keptnProject)– an open source enterprise-grade framework for shipping and running cloud-native applications – is going to eliminate the manual efforts in building, maintaining and extending pipelines. Alois Reitbauer, Head of the Dynatrace Innovation Lab, gives us the background on how keptn evolved, which cloud native best practices are implemented as core capabilities, how to contribute to this project and gives us a glimpse into where the journey is going. Visit the about page and join the community and make sure to deploy keptn on your own Kubernetes clusters by simply following the step-by-step guides.https://keptn.sh/https://twitter.com/keptnProjecthttps://keptn.sh/about/https://keptn.sh/docs/

083 My career path towards Serverless and what I wish I had known about Lambda with Nicki Klein
Nicki (@nicki_23) was bored in finance, started to learn .NET development on the side and eventually won 250k at a hackathon she used for her startup. Now she is a “Digital” Technical Evangelist at AWS and spreads her passion about Serverless through twitch and shares her code examples on githubTune in if you want to learn more about which things you should know about Serverless and Lambda. We chat about IAM permissions, timeouts, API Gateway and how a CI/CD Pipeline for Lambdas should look likehttps://twitter.com/nicki_23?lang=enhttps://www.twitch.tv/awshttps://github.com/kneekey23

082 Adopting Cloud-Native in Enterprises with Priyanka Sharma
Is Cloud Native just a synonym for Kubernetes? How to make sense of the sea of tools & frameworks that pop up daily? What can we learn from others that made the transformation and most of all: Where do we start?We got answer to all these and many more questions from Priyanka Sharma (@pritianka) – Dir. of Alliances at GitLab and Governing Board Member at CNCF (Cloud Native Computing Foundation). In her work, Priyanka has seen everything from small startups to large enterprises leveraging Cloud Native technology, tools and mindset to build, deploy & run better software faster. She advises to start incrementally and whatever you do in your transformation make sure to always focus on: Visibility (which leads to transparency), Easy of Collaboration (which increases productivity & creativity) and Setting Guardrails (this ensures you stay compliant & avoids common pitfalls).We ended the conversation around the idea of needing “Cloud Native Aware Developers” which can follow best practices or standards such as those promoted by CNCF or OpenSource projects such as keptn.shhttps://twitter.com/pritiankahttps://www.cncf.io/https://keptn.sh/

081 Mastering Memory Aware .NET Software Development with Konrad Kokosa
The .NET Runtime – whether .NET Framework or .NET Core – provides many ways to optimize memory management. But they don’t come in the form of configuration switches as we know if from Java. While there are a handful of settings, the .NET Runtime favors a different approach: asking developers to write memory aware software that follows a couple of core memory aware principles and best practices.In this podcast we get to talk with Konrad Kokosa (@konradkokosa) – author of Pro .NET Memory Management. In his book he gives developers and operators great tips on how to optimize your .net applications and environments such as #1: start with proper monitoring; #2: reduce memory allocations; #3: well – for this and more you should check out Konrad’s book.Listen in to a great discussion with somebody that has been working very close with the .NET Engineering Teams over the past years and brings the internal secrets of .NET Memory Management to everyone out there that wants to write Memory Aware .NET Software!https://prodotnetmemory.com/https://twitter.com/konradkokosa

080 The AI to Automate Behavior Driven Test Automation with Thomas Rotté from Probit
Creating and maintaining test scenarios not only takes a lot of time, but means we are creating artificial test scenarios based on what we think users are going to do versus replicating real users behavior. In this episode we invited Thomas Rotté, one of our friends from https://probit.cloud, who solved these problems for their work at KBC Bank. Their solution is an AI that learns behavior of real user traffic, creates a probability model for most common user journeys and uses that model to create automation test scripts on the fly for automated, real user simulating test bots. We also learn how GDPR and other challenges influenced their solution and how they are now working with other tool vendors and enterprises to bring this technology to the market.
