“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

We all want to leverage technology to solve problems. New and shiny toys are appealing to look which sometimes means we loose the insights on the base technologies that powers most of our connected lives, such as DNS or TLS.In this podcast we invited Philipp Krenn (@xeraa), Dev Advocate Team Lead at Elastic, and learn about DNS, TLS and other bad config changes. We learn about Log4Shell, how the Java Security Manager was a big help in fighting Log4Shell, why its been deprecated and also get his thoughts into CDD (Conference Driven Development)And if you ever visit Vienna – chances are you meet Philipp dancing Waltz with tourists 😊Show Links:To learn more from Philipp start withHis personal website: https://xeraa.net/Twitter: https://twitter.com/xeraaLinkedIn: https://www.linkedin.com/in/philippkrennHis conference schedule (past & future): https://xeraa.net/events/

How do you a design a feature if you don’t know for whom it is for? How do you define SLOs (Service Level Objectives) if you don’t know what your users expect from you? How do you design performance tests and workloads if you don’t know which user behavior to simulate?In this episode we have Barbara Ogris, Sr Product Experience Designer at Dynatrace, who walks us through the concept of target personas that she helped establish within Dynatrace. It changes product and observability discussions from “as a user I want …” towards “as Archie I have this need …”. Listen in and learn about design thinking, using empathy maps to define your target persona and how this can be applied to many aspects in software engineering.Barbara on Linkedinhttps://www.linkedin.com/in/barbara-ogris-6a0b6011b/Dynatrace Blog: Terminology matters: how to enhance user experience by aligning names with expectationshttps://www.dynatrace.com/news/blog/terminology-matters-how-to-enhance-user-experience-by-aligning-names-with-expectations/Atlassian persona template: https://www.atlassian.com/software/confluence/templates/personaMIRO persona template: https://miro.com/aq/ps/templates/personas/?utm_source=google&utm_medium=cpc&utm_c[…]aIQobChMI6J7Juqql-QIVCOJ3Ch3jtwWwEAAYASAAEgLxT_D_BwE&loc=9062705Adobe XD: how to define a persona: https://xd.adobe.com/ideas/process/user-research/putting-personas-to-work-in-ux-design/

SRE vs DevOps, SRE or DevOps or is it SRE & DevOps? No better person to ask than somebody that has been an SRE for much longer than our industry is talking about Site Reliability Engineering.Michael Wildpaner, Sr Engineering Director Cloud Security at Google, started as an SRE for Google Maps back in 2006. Fast forward to 2022 Michael has a lot of hands-on experience about the SRE role, the different levels of SRE that one organization can apply and how it connects with DevOps.Tune in and hear his personal stories from more than 15 years at Google. While not everyone is Google – there for sure is a lot we can take out of this conversation. Here some of my personal take awaysCore idea of SRE: take engineers that understand distributed systems and “annoy” / guide developers to build better resilient systems from the startDesign for automation: this already starts with naming your infrastructure (aka – don’t use lord of the rings names)SREs help so that you DO NOT DESIGN yourself into a cornerObservability is the foundation of good SRE as it enables incident management, insights all the way up to user insightsTip: Ensure new hires understand that you have a blameless culture As follow up material check out those linksLinkedIn: https://www.linkedin.com/in/michael-wildpanerTalk at DevOps Fusion 2022: https://devops-fusion.com/en/speaker/michael-wildpaner/

For some out there SLOs (Service Level Objectives) are the silver bullet to building and operating reliable software. But nothing is as shiny on the inside as it looks on the outside.In this episode we invited Stephen Townshend, former Performance Engineer now converted to Site (Slight) Reliability. Stephen (@the_kiwi_sre) has experienced the tough side of establishing SLOs within an organization. It’s a constant battle between focusing on reliability and new features and a lack of change in culture.Listen in and learn about the 9 pre-requisites for SLOs that Stephen has identified such as: having a certain level of observability, define clear business objectives, define ownership and give autonomy or establishing a blameless cultureStephen on Linked inhttps://www.linkedin.com/in/stephentownshend/Stephen on Twitterhttps://twitter.com/the_kiwi_sreHere the additional resources we brought up during our talk:Slight Reliability YouTube: https://www.youtube.com/c/SlightReliabilitySlight Reliability Podcast: https://www.buzzsprout.com/1698445Our LinkedIn discussion: https://www.linkedin.com/posts/scottmooreconsulting_7-steps-to-identify-and-implement-effective-activity-6938919857459462144--RI7LinkedIn: https://www.linkedin.com/in/stephentownshend/Twitter: https://twitter.com/the_kiwi_sre

Security is everyone’s business. And as everyone seems to be moving to Cloud Native it's important to understand what the security landscape in k8s, containerized apps, serverless, … looks like.To learn more about this we invited Anais Urlichs (@urlichsanais), Developer Advocate at Aqua Security and CNCF Ambassador of the year 2021. Over the past years Anais has educated thousands of people on cloud native, devops and security on her YouTube Channel.Tune in and learn more about the different approaches to security in cloud native, which open source projects are out there and how her advise on embedding security in your day2day work.Some additional links we discussed can be found here:Anais on Linkedin: https://www.linkedin.com/in/urlichsanais/Anais on Twitter: https://twitter.com/urlichsanaisTrivy: https://github.com/aquasecurity/trivyWeekly DevOps Newsletter: https://anaisurl.com/WTFisSRE Talk: https://www.youtube.com/watch?v=0zL61AiOaK0Anais’s YouTube channel: https://www.youtube.com/c/AnaisUrlichsAqua Open Source YouTube Channel: https://www.youtube.com/channel/UCb4mfRT5UWpjoUQRcIE2qOQ

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. We also talked about the late Abel Wang and how Microsoft UK is supporting Girls Who Code.Show Links:April on Linkedinhttps://www.linkedin.com/in/azureapril/April on Twitterhttps://twitter.com/TheAprilEdwardsPutting the Ops into DevOps keynotehttps://globalazure.at/sessions/#323994Supporting Girls Who Code in memory of Abel Wanthttps://www.justgiving.com/fundraising/msbuild2022/?WT.mc_id=modinfra-67727-apedward
