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.

074 Advanced Real User Monitoring Tips & Tricks with Ben Rushlo
Happy Guy Fawkes Night!In the first episode with Ben Rushlo, Vice President of Dynatrace Services, we learned about things like not getting fooled by Bot traffic, which metrics to monitor and how RUM can replace your traditional site analytics.In this episode we dive deeper into RUM use cases around user behavior analytics, bridging the silos between Dev, Ops & Business and elaborate on why blindly optimizing individual page load times is most likely wasted time as you won’t impact what really matters: End-to-End User Experience!In our discussion we also talked about UX vs UI as well as importance of Accessibility. Here two links we want you to look at: Holger Weissboeck on Let’s put U in UX and Stephanie Mcilroy’s presentation at DevOne.Listen to Episode 70:https://www.spreaker.com/user/pureperformance/070-exploring-real-user-monitoring-with-Let's Put the U in UX:https://www.youtube.com/watch?v=qi19hls9LfYStephanie Mcilroy’s presentation at DevOne:https://devone.us/speakers/#stephaniemcilroyData vs. Info article Brian mentioned:https://medium.com/@copyconstruct/monitoring-in-the-time-of-cloud-native-c87c7a5bfa3e

073 Understanding Azure Service Fabric with Sravan Rengarajan
Did you know that Azure Service Fabric is used by most of Microsoft’s global high scale services such as Bing, Dynamics or Xbox)? It’s a battle tested distributed systems platform that enables developers to deploy, manage and scale their microservices. In this session we have Sravan Rengarajan, Program Manager at Microsoft Azure, giving us an overview of the key use cases, how Service Fabric started and in which direction it is heading. We also learn how you get your own free local version of Service Fabric and why Service Fabric gets us towards real Serverless computing. Additional information can be found on the Service Fabric GitHub codebase – yeah – its all out there on GitHub!https://www.linkedin.com/in/sravan-rengarajan/ - Sravan on Linkedinhttp://aka.ms/servicefabricdocs - learn more about Service Fabrichttp://aka.ms/servicefabricmesh - learn more about Meshhttp://aka.ms/tryservicefabric - free clusters to party on!https://github.com/microsoft/service-fabric - GitHub codebase

072 Monitoring Minecraft – Why and What to Learn from it with Mike Villiger
Minecraft – the hugely popular sandbox video game – might not be your traditional software to monitor with an APM (Application Performance Management) tool. But Mike Villiger did it anyway in order to learn some advanced concepts in application monitoring such as custom entry points, thread diagnostics, method hotspots or simply to figure out why his mod’ed Minecraft sometimes couldn’t keep up with processing all the changes and skipped cycles. By using Dynatrace – first AppMon now Dynatrace SaaS – he learned more about the internals of Minecraft, how the single threaded architecture calls each mod and why a single mod must not take longer than 50ms to process. Mike gives us insights into which problems he found within Minecraft but more importantly what he takes away for his daily job as a performance advocate and evangelist. If you have any interesting side projects where you use APM tools let us know – there is always something to learn from every project!https://minecraft.net/https://twitter.com/mikevilliger

071 Lessons learned when breaking a Monolithic Healthcare System with Brett Hofer
Brett Hofer is giving us his inside story on how he was called for the rescue to break a monolithic healthcare system that, after 3 years of development, was on the verge of having a major business impact on the largest healthcare vendor in the US. We learn about his strategic decisions such as quieting the system, establish traceability and most importantly: setting up a separate team that broke the monolithic while keeping it in sync with the main branch development. Brett Hofer is now Global Practice Lead at Dynatrace where he and his team help Dynatrace customers successfully walking through their digital transformations.https://www.linkedin.com/in/brett-hofer-2432572/

069 Four Serverless Patterns everyone should know with Justin Donohoo
Serverless has been a hot topic for quite a while, but we are still in the early stages when it comes to best practices and tooling. Justin Donohoo, Co-Founder of observian.com, gives us the pros and cons of 4 architectural patterns that he calls: “Microservice / nano pattern”, “Service Pattern”, “Monolithic Pattern” and the “GraphQL Patterns”. Besides these patterns we also learn about common cost traps and how to “architecture around them”. For more information on serverless Justin also shared his recent Serverless Meetup presentation. And stay tuned – there will be more from Justin around secrets, containers and anything else there is to know about cloud native applications.* https://twitter.com/justindonohoo* https://www.observian.com/* https://docs.google.com/presentation/d/1ffx9wWioFahxQJbhpPhJ3FC-csNXrdEGdufrj5LwV6w/edit#slide=id.p* https://observian.com/tools/secret-awsome/* https://www.puresec.io/blog

067 Redefine Testing for Microservice Delivery Pipelines with Chris Burrell
How can you get your build times down to minutes? Exactly: eliminate the largest time consumer! At Landbay, where Chris Burrell heads up technology, this was end-to-end testing.Landbay deploys their 40 different microservices into ECS on a continuous basis. The fastest deployment from code to production is 6 minutes. This includes a lot of testing – but simply not the traditional end-to-end testing any longer. Chris gives us insights in contract testing, mocked frontend testing, how they do Blue/Green deployments and what their strategy is when it comes to rollback or rollforward.For more information watch Chris’s talk on 6 minutes from Code Commit to Live at µCon and his lightening talk on CDC Testing is Dead – Long Live Swagger.https://twitter.com/ChrisBurrell7https://skillsmatter.com/skillscasts/10714-6-minutes-from-code-commit-to-live-you-won-t-believe-how-we-did-ithttps://skillsmatter.com/skillscasts/11147-lightning-talk-cdc-testing-is-dead-long-live-swagger#video

066 Load Shedding & SRE at Google with Acacio Cruz
Have you heard about Load Shedding? If not then dive into this discussion with Acacio Cruz, Engineering Director at Google ( https://twitter.com/acaciocruz ). He walks us through what Google learnt from one of the early outages at Gmail and how he and his team are now applying concepts such as load shedding to avoid disruption of their services despite spikes of load or unpredictable requests. We also discuss SRE (Site Reliability Engineering), how it started and transformed at Google and how we should think about automation, configuration of automation, and automation of automation. For more details – including visuals – we encourage you to watch Acacio’s breakout session from devone.at on YouTube (Load Shedding at Google).https://devone.at/speakers/#acaciocruzhttps://www.youtube.com/watch?v=XNEIkivvaV4

065 Running a successful internal bug bounty program with Pascal Schulz
Security is on everyone’s mind. One way to strengthen security of your software and increase the awareness of your engineers is running a Security Hackathon – or a “Bug Bounty Program”. We invited Pascal Schulz ( https://www.linkedin.com/in/pascalschulz/ ), Security Engineer at Dynatrace, to the show to give us more background on HACK.DT – a security hackathon he and his team ran earlier this year within the Dynatrace Engineering Labs. For additional details check out his blog Running a successful internal bug bounty program and ping him on twitter (@PascalSec) in case you have further questions.https://www.dynatrace.com/news/blog/running-a-successful-internal-bug-bounty-program/
