    The SLO Dilemma: Slight Reliability Discussions with Stephen Townshend

    The SLO Dilemma: Slight Reliability Discussions with Stephen Townshend

    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 culture

    DevOps is 80% culture: But what does this really mean with April Edwards

    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.

    Introducing OpenFeature – Stepping into the footsteps of OpenTelemetry with Mike Beemer and Todd Baert

    Introducing OpenFeature – Stepping into the footsteps of OpenTelemetry with Mike Beemer and Todd Baert

    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 Beemer 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 podcast

    Getting Started with Chaos Engineering through Game Days with Mandi Walls

    Getting Started with Chaos Engineering through Game Days with Mandi Walls

    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.

    In our talk we mentioned a couple of resources – here they are:

    Why SREs are not your new Sys Admins with Hilliary Lipsig

    Why SREs are not your new Sys Admins with Hilliary Lipsig

    “The most significant body of my SRE work is architectural reviews, disaster and failover planning and help with SLIs and SLOs of applications that would like to become SRE supported.”

    This statement comes from Hilliary Lipsig, Principal SRE at Red Hat, as her introduction to what the role of an SRE should be. Hilliary and her teams are helping organizations getting their applications cloud native ready so that the operational aspect of keeping a system up & running and within Error Budgets can be handled by an SRE Team.

    Listen in to this episode and learn about the key advices she has for every organization that wants to build and operate resilient systems. And understand why every suggestion she makes has to be and will always be evidence-based!

    In the talk we mentioned a couple of tools and practices. Here are the links:
