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.

    Encore - How to build distributed resilient systems with Adrian Hornsby

    Encore - How to build distributed resilient systems with Adrian Hornsby

    Adrian Hornsby (@adhorn) has dedicated his last years helping enterprises around the world to build resilient systems. He wrote a great blog series titled “Patterns for Resilient Architectures” and has given numerous talks about this such as Resiliency and Availability Design Patterns for the Cloud at DevOne in Linz earlier this year.

    Listen in and learn more about why resiliency starts with humans, why we need to version everything we do, why default timeouts have to be flagged, how to deal with retries and backoffs and why every distributed architect has to start designing systems that provide different service levels depending on the overall system health state.

    Service Meshes: From simple load balancing to securing planet scale architectures with Sebastian Weigand

    Service Meshes: From simple load balancing to securing planet scale architectures with Sebastian Weigand

    Whether you are still researching on whether you need a Service Mesh or simple use a load balancer or if you are already deploying multi hybrid-cloud architectures and Service Meshes help you secure the location aware routed traffic. In both cases: listen to this episode!

    We invited Sebastian Weigand (@ThatDevopsGuy) back to our podcast who wrote papers such as Building a Planet-Scale Architecture the Easy Way. In our episode Sebastian walks us through why Service Meshes have gained so much in popularity, what the main use cases are, how you should decide on whether or not use Service Meshes and which challenges you might run into as you expand into using more features.

    From Postmortems to true SRE Culture with Steve McGhee

    From Postmortems to true SRE Culture with Steve McGhee

    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.

    SLO Adoption and Usage in SRE with Sebastian Weigand

    SLO Adoption and Usage in SRE with Sebastian Weigand

    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.

    Building High Performing Apps on React with Cassidy Williams

    Building High Performing Apps on React with Cassidy Williams

    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).
