Datanauts 089: SRE vs Cloud Native vs DevOps

Rob Hirschfeld joins the Datanauts to talk about the term Site Reliability Engineer (SRE) and what it means for IT operations.

Rob explores how the SRE designation is an effort to put operations teams on a more equal footing with developers within an organization. Rob and the Datanauts also discuss how SREs line up with other industry trends such as the cloud native and DevOps movements. LISTEN HERE

Why Does DevOps Require a New Operating Model? By Mustafa Kapadia @MKapadiaTweets

For many, redesigning the operating model is table stakes for a successful DevOps transformation. But have you ever wondered why? Popular wisdom will have you believe that the main reason for operating model redesign are to…

“Improve collaboration between business and IT”
“Realign metrics”
“Take full advantage of the new tools”
“And even jump start culture change”

While these are all good reasons, frankly they miss the point. Experience suggests there is a more practical reason – match ownership with desired output.

What do we mean by that? Well first, let’s look at how the current model works. READ MORE

What can developers learn from being on call? By Julia Evans @b0rk http://jvns.ca/blog/2017/06/18/operate-your-software/

We often talk about being on call as being a bad thing. For example, the night before I wrote this my phone woke me up in the middle of the night because something went wrong on a computer. That’s no fun! I was grumpy.

In this post, though, we’re going to talk about what you can learn from being on call and how it can make you a better software engineer!. And to learn from being on call you don’t necessarily need to get woken up in the middle of the night. By “being on call”, here, I mean “being responsible for your code when it breaks”. It could mean waking up to issues that happened overnight and needing to fix them during your workday! READ MORE

Kargo Ansible Playbooks foster Collaborative Kubernetes Ops

Why Kargo?
Making Kubernetes operationally strong is a widely held priority and I track many deployment efforts around the project. The incubated Kargo project is of particular interest for me because it uses the popular Ansible toolset to build robust, upgradable clusters on both cloud and physical targets. I believe using tools familiar to operators grows our community.

We’re excited to see the breadth of platforms enabled by Kargo and how well it handles a wide range of options like integrating Ceph for StatefulSet persistence and Helm for easier application uploads. Those additions have allowed us to fully integrate the OpenStack Helm charts (demo video). READ MORE
