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.
State of Web Performance Optimization in 2021 with Sergey Chernyshev
Like many frontend developers, Sergey Chernyshev was inspired in the late 2000 by Steve Souders to contribute to and grow the web performance community. Not only did he launch the Meed4SPEEDs as part of the New York Web Performance Meetup. He also worked for meetup.com helping them to improve web performance and user experience. Over the past years Sergey contributed to many projects such as WebPageTest.org, UX Capture Library, Jamstack and more.
Tune in to this episode, learn what has and what hasn’t changed in the quest for better user experience. Get a quick start on Core Web Vitals and current challenges. Most important: get inspired to contribute back to this community.

Shift-Left Load Testing is a LIE with Hassy Veldstra
In his SLOConf talk Production load testing as a guardrail for SLOs and in his blog Production Load Testing, Hassy Veldstra, founder of artillery.io makes the case for load testing in production. It helped him in various organizations to establish SLOs (Service Level Objectives) and change the way engineers think about performance. He got inspired by Building Evolutionary Architectures which introduces the concept of performance as a fitness function.
Tune in into our conversation, hear our arguments pro and contra load testing in the various environments and learn why in the end we agreed on the fact that SLOs – while nothing really new – are a great chance to re-define performance engineering.

Making the case for SRE in a DevOps organization with Bart Enkelaar
How do you convince an organization that just went through a 2 year DevOps transformation to continue the journey by applying SRE practices? What is SRE anyway? What are good SLOs? And how do you get development teams to take responsibility for their code in production?
Bart Enkelaar, Lead Site Reliability Engineer at bol.com, not only got their organization to apply SRE practices, define good SLOs and got dev teams to rotate on-call duties. He also followed the advice of Margaret, Chief Platform Officer, to bring his personal passion to the job. This led to inspiring and educating the community about SRE and SLO through music. To see what I mean check out Barts The Game of SLOs – a three part reliability musical from SLOConf or his funny tech conversations at Friendly Tech Chats.

The future of security is open source and Falco leads the way with Dan Pop
While some think about the late Austrian musician, Dan POP and the CNCF community thinks about modern security when it comes to Falco.
Listen in and hear directly from Dan (@danpopnyc) who, besides doing many things in the CNCF community, also hosts POPCAST where he started connecting technology leaders during the last year. In the podcast you learn a lot about security, the power of eBPF and how Falco aims to contribute to runtime security like k8s contributed to distributed computing.

Roadmap to k8s, DevOps and more with Nana
Wonder what you learn when building k8s from scratch for a large enterprise? Wonder what you learn when automating delivery by connecting your different DevOps tools together?
Nana Janashia runs one of the most successful technical YouTube channels called TechWorld with Nana where she covers topics ranging from containers, docker, k8s, cloud native and DevOps. She basically takes her lessons learned and explains technologies and concept in a very easy way especially for folks that want to get started with.
In this episode we focus a lot on DevOps, what the right trades of a DevOps engineer are and how to get started. Thanks Nana for your time and all the additional resources we talked about during the episode that are listed below:

Old Patterns powering modern tech leading to same old performance problems with Taras Tsugrii
Have you ever thought about reorganizing data allocation based on production telemetry data? Have you ever thought about shifting compiler budgets to parts of your code that is heavily executed based on profiling information captured from your real end users? Whether the answer is yes or no you will be fascinated by Taras Tsugrii, Software Engineer at Facebook, who is sharing his experience on optimizing everything from compilers, to databases, distributed systems or delivery pipelines.
If you want more after listening to this episode check out his recent talk at Neotys PAC titled “Old pattern powering modern tech”, subscribe to his substack newsletter, his hashnode blog, or the conference recordings of Performance Summit and Scaling Continuous Delivery.
