Has one of the decision makers in your organization decided that you have to go "all in on technology X" because they saw a great presentation at a conference or got a great sales pitch from a vendor? If that is the case then this episode is for you and you should forward it to those decision makers.Sebastian Vietz, Director of Reliability Engineering and Host of the Reliability Enablers Podcast, shares his thoughts on considerations when picking a technology like Serverless. We discuss the importance of knowing limits, best fit architectural patterns and things that should influence your technology decisions!Being aware of coldstarts, a 20000 concurrent request limit or 512mb being an ideal size for Lambda are just some of the things we can all learn from Sebastian.Additional links we discussed:Sebastians LinkedIn: https://www.linkedin.com/in/sebastianvietz/Reliability Podcast: https://podnews.net/podcast/ibe8kMore things on serverless: https://serverlessland.com/

When thousands of systems show a blue screen - which ones do you fix first to quickly bring up your most critical systems? For that you need to know which systems are impacted, which mission critical applications run on it, and which depending systems are also impacted by something like the recent CrowdStrike incident!We have invited Josh Wood, Principal Solutions Engineer at Dynatrace, who was one of the first responders helping organizations to leverage observability data to identify which systems to fix first to bring critical apps such as ATMs, Self-Service Terminals, POS (Point of Sales), ... back up again quickly.In this special episode Josh is walking us through the technical details of the CrowdStrike BSOD (Blue Screen of Death), what caused it, how to leverage observability to get a priorities list of systems to fix first and what organizations can do to prevent software impacting issues in the future.Here the links we discussed in the episode:Josh on LinkedIn: https://www.linkedin.com/in/joshuadwood/Josh's blog on CrowdStrike BSOD: https://www.dynatrace.com/news/blog/crowdstrike-bsod-quickly-find-machines-impacted-by-the-crowdstrike-issue/CrowdStrike Incident Takeaway Blog: https://www.dynatrace.com/news/blog/crowdstrike-incident-revisiting-vendor-quality-control/ 

WebAssembly runs in every browser, provides secure and fast code execution from any language, runs across multiple platforms and has a very small binary footprint. It's adopted by several of the big web-based SaaS solutions we use on a daily basis. But where did WebAssembly come from? What problems does it try to solve? Has it reached critical adoption? And how about observing code that gets executed in browsers, servers or embedded devices?To answer all those questions we invited Matt Butcher, CEO at Fermyon, who explains the history, current implementation status, limitations and opportunities that WebAssembly provides.Further links we disucssedLinkedIn Profile: https://www.linkedin.com/in/mattbutcher/Fermyon Dev Website: https://developer.fermyon.com/ The New Stack Blog with Matt: https://thenewstack.io/webassembly-and-kubernetes-go-better-together-matt-butcher/ 

"Because I don't want software to go down every single day in my next gig!" is what drives the motivation of Ash Patel, Reliability Advocate and Podcast host of SREpath, to talk about and educate IT professionals on the importance of building and operating reliable systems.For 15 years Ash used to be Director of Operations at a private health service organization. He has experienced that patients couldn't get the treatment they expected due to unreliable software he was responsible for. In our conversation Ash talks about how he had to close the knowledge gap on technology but also solve the problem by having engineers understand the pain and the requirements of their end users. One way to educate more engineers is through his podcast called SREpath where Observability has become a hot topic recently. Tune in, hear about the memorable stories from his guests from CapitalOne, IKEA and SquaredUp, and lets move towards a world where software is reliable by default.Links as discussed today:Ash on LinkedIn: https://www.linkedin.com/in/ash-patel-srepath/SREpath Podcast: https://www.srepath.com/podcast/Clearing Delusions in Observability https://read.srepath.com/p/30-clearing-delusions-in-observability-2af Boosting your observability data's usability https://read.srepath.com/p/35-boosting-your-observability-datas-3f4 How to Enable Observability for Success https://read.srepath.com/p/40-how-to-enable-observability-for

"Meet your users where they are!" - For Platform Engineering Teams that means understanding the current way your engineers work, understand their pain, and provide a solution that doesnt force them to change their behavior but provides a 10x efficiency improvement. Thats not easy to achieve but is what we discussed with Abby Bangser in our latest episodeAbby is a Team Topologies Advocate, has spent years at Thoughtworks helping organizations transform through Delivery Platforms and is now a Lead at the CNCF Platform Working Group. Tune in and hear our discussions on Why Platform Engineering is nothing new, how to avoid Platform Engineering Teams to become your next bottleneck and silo, why Platforms need to have more than one interface and why the purpose of Platform Engineering should be to bring good Developer Experience to all engineersHere all the links we discussed during this episodePlatform Engineering Maturity Model: https://tag-app-delivery.cncf.io/whitepapers/platform-eng-maturity-model/CNCF Platform Working Group: https://tag-app-delivery.cncf.io/wgs/platforms/KubeCon 2024 Talk: https://colocatedeventseu2024.sched.com/event/1YFdf/sometimes-lipstick-is-exactly-what-a-pig-needs-abby-bangser-syntasso-whitney-lee-vmwareGitHub Issue for Questionnaire: https://github.com/cncf/tag-app-delivery/issues/635Kratix: https://www.kratix.io/Abbys LinkedIn: https://www.linkedin.com/in/abbybangser/Abbys Events: https://www.paintedwavelimited.com/events
