Steve McGhee (@stevemcghee) is an expert in post mortems and SRE. He has learned the craft at Google, applied it at MindBody and is now sharing his experiences while back at Google to the larger SRE community. Listen to this episode and learn more about how post mortem analysis can be the starting point of your SRE transformation. How it can help reliability engineering to build and engineer systems that fail gracefully instead of causing full crashes or outages.

Steve also went into monitor what matters and only defining alerts on leading indicators with an expiration date – a fascinating concept to avoid a flood of custom alerting in production!

If you want to learn more from Steve or SRE check out these additional resources he mentioned in the podcast: The SRE I aspire to be (SRECon19) and his 2 blog part series on blameless.com.

Keep hearing the terms SLIs, SLOs, SLAs, Error Budgets and finally want to understand what they are, who should be responsible for and how they fit into SRE (Site Reliability Engineering)?

Then listen to our conversation with Sebastian Weigand who has been helping organizations modernizing not only their application stacks but also helping them embrace DevOps & SRE. Learn about who is responsible to define SLIs, what the difference between SLOs and SLAs are and what the difference between DevOps & SRE is in his opinion!

Sebastian, who calls himself “That Devops Guy” (@ThatDevopsGuy), also suggests to check out the latest free report on SLO Adoption and Usage of SRE as well as SRE Books from Google to get started with that practice.

Cassidy (@cassidoo) has been building but also educating developers on how to build apps on React, JavaScript, JAMStack and many other technologies over the past years. We got her on our podcast where she gave us insights into React Hooks, how WPO (Web Performance Optimization) plays out in the React world, why it is important to think about state from the start and that its important to always have your end user in mind before even writing your first line of JavaScript.

In the podcast she references additional resources which here are the links for: The performance benefits of Variable Fonts, Mandy Michael (@Mandy_Kerr), Isabela Moreira (@isabelacmor) and A/B Testing with React (YouTube).

How do you prepare for a 2Mio concurrent user load that lasts for 7 seconds? What does the load infrastructure look like? How do you optimize your scripts? How do you deal with DNS or CDNs?

In this episode we hear from Joerek van Gaalen who has done these types of tests. He shares his experiences and approaches to running these “special event extreme load tests”. If you want to learn more make sure to check out his presentation and read his blog post from Neotys PAC 2020.

Have you ever burned 30k because you forgot to turn off your test VMs over the weekend? Have you ever accidentally deleted “the production table” because you thought you were connected to your dev database? We often only hear the good stories and not those that teach us about what we should not do in order to avoid disaster!

Join this episode where Justin Donohoo, Founder and CTO of Observian, tells us horror stories from his professional life that taught him great lessons on what not to do when moving to the cloud, re-architecture because of exponential growth or let the intern do things he/she shouldn’t do.

Goranka Bjedov has seen the different sides of Open Source while she was working for organizations such as Google, Facebook or AT&T Labs. Before she takes the stage at www.devone.at later this year she gives us her take on Scott McNealy’s quote “Open Source is free like a puppy is free”. Tune in and hear her thoughts on how to pick the right tools, languages or frameworks, how to grow a an open source project and what things you should definitely avoid.

Starting your new job as Infrastructure Engineer in a large bank with your to-be boss and his key architects just leaving feels like Chaos! Maybe that’s why Tammy Butow has made a career in Chaos and Site Reliability Engineering. In this episode, Tammy shares her experiences of bring reliability into highly complex systems at NAB, Digital Ocean, DropBox or now Gremlin through chaos engineering. You learn about the importance to know and baseline your metrics, to define your SLIs and SLOs and to continuously run your fire drills to ensure your system is as reliable as it has to be.

If you want to learn more check out Tammy’s presentations on speakerdeck and make sure to join the chaosengineering slack channel.

3 years ago, Adam Auerbach explained how he helped Capital One to automate performance into the DevOps Delivery Pipeline. In 2020, where IT Security is a hot trending topic, Adam works for EPAM and is back advocating for the same shift-left he as advocated for when it comes to functional or performance testing. But now – its about baking Security into your practices & culture. And he has a cool word for it: DevTestSecOps!

Listen in and learn which types of security checks can be fully automated in the different stages of the delivery pipeline. Also learn how to prioritize your vulnerabilities as you most likely end up with a lot of noise in the beginning. Adam also highlightes the following open source tools that will help in that transformation: getcarrier.io and reportportal.io.

DesignOps, just as DevOps or NoOps, is targeted towards increasing the efficiency and collaboration between designers and engineers in order to deliver better, intuitive and consistent user experiences. It requires changes in processes, people and tooling and is heavily driven by enabling engineers to become more autonomous when developing and delivering new value for their organization.

Join this podcast and learn from Ursula Wieshofer (@Ursula_W), UX Design Team Lead, as well as from Fabian Friedl (@fabian_friedl), DesignOps Team Lead, on how we live and breath DesignOps at Dynatrace. You will learn about the recently released OpenSource Design System Barista, how it enables our engineers to deliver consistent user experiences across all sorts of software projects and how we manage feedback through the Barista GitHub project for future innovation.

Also make sure to check out the recent blog posts UX Guilds as well as how we deal with the constantly changing requirements of our design teams.

We're back to our regular scheduled show!

Kelsey Hightower (@kelseyhightower) has worn many hats as it says on his bio but we also learned from him that he probably doesn’t have that many hats at home as he has been living a minimalistic life over the past couple of years. A philosophy as we learn in this podcast that also goes well when it comes to building your next platform on Kubernetes.

In this podcast we learn about the do’s and don’ts, how you should plan and test for k8s upgrades, which tradeoffs you have to take as it comes to performance, how to think about developer productivity on k8s and why it is important to read up on security as it relates to the software we build, deploy and run on our k8s clusters.

Thank you Kelsey for supporting our community with your time and expertise. Hope to have you back in the future!
