“I was not that interested in coding but more in understanding the impact of software on human beings” says Diana Najda, SRE & Monitoring Lead, when we asked her how she ended up leading the efforts around Site Reliability Engineering.Tune in to our conversation and learn how Diana is bridging the gap between Dev, Ops and Business by ensuring that the right people get the right telemetry data from their observability platform. She gives us insights into her definition of DevOps and SRE, how she helps teams setting up SLOs (Service Level Objectives) and how she proves the ROI (Return On Investment) into the SRE practices!Last piece of advice Diana gives everyone interested: “SRE might be buzzword it loses the buzz the more you hear it – BUT - its really cool because SREs make the life of Dev and Ops easier every day”If you want to connect with Diana reach her on LinkedIn: https://www.linkedin.com/in/diannajda/

Serverless and other emerging technologies hide the complexity of the underlying runtimes from developers. This is great for productivity but can make it really hard when troubleshooting behavior that needs deeper insight into those runtimes, platforms or frameworks.In this episode we hear from Kam Lasater, Founder of Cyclic Software. Kam has run into several walls while he was implementing solutions from scratch using Serverless technologies as well as other popular cloud services. He recently presented a handful of those scenarios at DevOpsDays Boston 2022.Tune in and learn from Kam as he walks us through two of those challenges he covered during his DevOpsDays talk.

Over the years we learned how to optimize the performance of our JVMs, our CLRs or our databases instances by tweaking settings around heap sizes, garbage collection behavior or connection and thread pools.As we move our workloads to k8s we need to adapt our optimization efforts as they are new nobs to turn. We need to factor in how resource and request limits on pods impact your application runtimes that run on your clusters. Out of memory problems are all of a sudden no longer just depending on the java heap size alone!To learn more about k8s optimization best practices we have invited Stefano Doni, CTO of Akamas. Stefano walks us through key learnings as the team at Akamas has helped organizations optimize the performance, resiliency and cost of their k8s workloads. You will learn about proper memory settings, CPU throttling and how to start saving costs as you move more workloads to k8s.

In economic turbulent times leaders get asked questions like: “What’s the return on investment of your DevOps or Cloud Transformation? Did we really get better and more efficient? Or did we just blow a lot of money out the window?”Connecting business results with your technical initiatives is what would answer those questions. To learn how this works we invited Adam Dahlgren, SVP Product at Allstacks. From Adam we learn about Value Stream Management, how to align with your top level OKRs and how to improve your DORA and SPACE metrics. Because as Adam says in the beginning: “Inspection is coming especially during turbulent economic times and they will question your investment in transformation projects!” If you want to follow up with Adam check out the following links we discussed:LinkedIn: https://www.linkedin.com/in/adam-dahlgren/What are DORA Metrics: https://www.allstacks.com/blog/dora-metrics/?hsLang=enWhat is the SPACE Framework: https://queue.acm.org/detail.cfm?id=3454124Allstack: https://www.allstacks.com/DevOps World sessions from Allstack: https://events.devopsworld.com/widget/cloudbees/devopsworld22/conferenceSessionDetails?tab.day=20220929&search=dora

While this episode started out with a recap of April Edwards (@TheAprilEdwards) keynote called “Putting the Ops into DevOps” we quickly got April talk about what measures Microsoft has set to embrace the cultural change needed for their DevOps transformation: Every service has a public health dashboard, putting the customer in the center, make products open source, eat your own dog food, align your objectives with the team, …Besides this great conversation that finally gave some great input on what cultural change really looks like we learned from her background in Ops, moving to Dev, getting into the cloud and now inspiring Ops teams to have it easier in their job using automation. Tune in, learn and get inspired.

Feature Flagging has gained a lot of momentum which we can observe by counting the number of feature flagging solutions. To ensure a good developer experience when implementing feature flags the CNCF OpenFeature project was launched during KubeCon 2022 in Valencia. It is aiming to provide a feature flag standard similar to what OpenTelemetry did for Observability.Tune in to this podcast where we have two of the founding members Mike Beamer and Todd Baert explain why it was the right time to initiate the project, which problems it solves and what use cases feature flagging brings to organizations.If you want to learn more about the project check out the following resources discussed during the podcastWebSite: https://openfeature.dev/GitHub: https://github.com/open-featureCommunity: https://github.com/open-feature/communityITPro Today Launch Coverage: https://www.itprotoday.com/testing-and-quality-assurance/open-source-openfeature-project-takes-flight-advance-feature-flags

How do you plan for unplanned work such as fixing systems when they unexpectedly break in production? Just like firefighters – the best approach to practice those situations so that you are better prepared when they happen.In this episode we have Mandi Walls, DevOps Advocate at PagerDuty, explain why she loves Game Days where she is “practicing for the weird things that might happen”. Prior to her current role she worked for Chef and AOL – picking up a lot of the things she is now advocating for. In our conversation Mandi (@lnxchk) gives us insights into how to best prepare and run game days, shared her thoughts on what good chaos scenarios (unreliable backend, slow dns …) are and which health metrics (team health, # incidents out of hours, …) to look at in your current incident response to figure out what a good game day scenario actually is.Mandi on Linkedin: https://www.linkedin.com/in/mandiwalls/In our talk we mentioned a couple of resources – here they are:Mandi’s talk at DevOpsDays Raleigh: https://devopsdays.org/events/2022-raleigh/program/mandi-wallsOps Guides: https://www.pagerduty.com/ops-guides/
