Secure By Design Guests Dan Bergh Johnsson, Daniel Deogun, and Daniel Sawano host Jessica Kerr to discuss their book Secure by Design. Daniel: “There’s a lot of good designs which come naturally to us as programmers but which has the interesting side effect that they also prevent security-related bugs.” Domain Primitives The discusses domain primitives as an example of coding practices that naturally provide security through good design. Dan Bergh: “It’s a good starting point to understand that using domain-driven design not only makes your code more expressive, solves more domain problems. Even though these designs were not crafted to address security to start with, they’ve also had that as a side effect.” Jessica: “I love that what you’re recommending in this part is to think harder about what you do want in the system, express that in the code, and suddenly a bunch of things that you don’t want in the system just aren’t.” Testing The talks about the ways in which testing contributes to secure design. Daniel Sawano: “It tends to be so much easier and more robust if you start defining your own domain types.” Immutability The discusses the benefits of immutability. Dan Berg: “It’s possible to…configure and mutate them until they are kind of safe-ish.” Jessica: “Kind of safe-ish?” Dan Berg: “Well, we are on a DevOps podcast.” Logging The talks about the security implications of logging practices. Daniel Deogan: “One thing that’s very important is that if you put directly into your logs, it becomes an attack surface for second-order injection attacks.” Dan Bergh: “It’s a perfect launchpad for doing a really, really hard attack inside your system.” Daniel Deogan: “The common mistake that many developers do is that they more or less dump inputs blindly.” Jessica: “We have this illusion that logging is simple, but it isn’t.” Cloud Thinking The discusses the chapter on cloud thinking. Dan Bergh: “In a way, we’re instructing the system to become more intelligent.” Symmathesy! The book is available online in its entirety.

Referenced in the show Patrick discussed his love for continuous learning and referenced some of his favorite books. The Ironies of Automation is a paper discussing how automation can expand problems rather than eliminate them. Promise Theory is an approach to coordinating actors and agents in a system about their intentions to each other in the form of promises. The model was originally proposed by Mark Burgess NoEstimates: How to Measure Project Progress Without Estimating is a 2016 book that explains the “No Estimates” Agile concept.

Historical Context The discusses the origins of the book Team Topologies. The project started with a blog post. Matthew: “Back in 2013, I actually wrote a blog post in my personal blog. I actually wrote it in a rage.” In 2015, Manuel ed the team to help expand on the ideas from that blog post and create Devops Toplogies. Manuel: “What the hell are you calling a DevOps team? DevOps is not about creating a new team called DevOps.” DevOps Topologies The discusses the impact of DevOps Topologies and some of the companies that have used it, including Netflix and Conde Nast. Matthew and Manuel explain how the project has evolved over time as DevOps Topologies was being deployed in the real world. Matthew: “It’s not just a set of patterns or templates. We wanted to provide an organizational capability for detecting when things have changed and have gone wrong.” The discusses Conway’s Law and its implications for DevOps. Manuel: “Teams are the means of delivering value.” Flow! The discusses the importance of flow in both living systems and organizations. Manuel: “It’s a more experiment driven approach where we have this goal or this need we need to meet and then allowing the teams to find the right solution.” Jessica: “In modern systems, the flow is of changes to the flow of the product. It’s a very different level of work.” The discusses the need for different team configurations that are constantly evolving. Matthew: “It seems quite important to understand different kinds of dynamics in the organization at different times.” Three Team Interaction Modes The discusses the three team interaction modes laid out in the book: collaboration, as-a-service, and facilitation. Four Team Topologies The discusses the four team topologies in the book: value stream aligned teams, enabling teams, platform teams, and complicated subsystem teams. Jessica: “The limitation of a team is cognitive load. It’s not resources, it’s not pizza.” Manuel: “Although pizza is very appealing.” Manuel discusses Dunbar’s Number and how that concept can put useful constraints on teams. Buy the book!

Three recent ones in a row about k8s - the Kubernetes Best Practices book, Ian Coldwater, and Kelsey Hightower today. Trevor Catching Up With Steven Murawski Devopsdays Chicago 2019 Jessica The Meltwater Transformation What happened in 2019? Bridget Switched from devrel to product. Helped with Helm 3 launch!!! Traveled less. Dragged Joe to a personal trainer because if he’s going maybe I will too. Matty Lots of speaking (spoke at 24 conferences in 2019). Moved back to Chicago. Went to lots of devopsdays. Got even more interested in resilience engineering and realized I don’t know shit. Trevor More travel! A lot of customer work, focus on delivering solutions, now moving officially into product. I also got really into shuffleboard and DND Jessica Consulting!

In this episode, host Jessica Kerr is ed by guests Gene Connolly and Joan Freed to discuss DevOpsiCon and their DevOps transformation at Meltwater. DevOps at Meltwater The discusses how DevOps has transformed the working environment at Meltwater. When Joan started at Meltwater, engineering and operations were kept entirely separate. Joan: “There was this huge wall because engineering knew how things were built and operations knew the production systems…but there wasn’t any cross-pollination there.” The lack of communication between the teams caused friction and slowed down product delivery. The process could take as long as six months. Joan: “We’re a Software as a Service company so we always want to build products that are sticky and keep our customers around.” Joan discusses how Meltwater began to move to a more agile business model. Getting engineers and operations people in the same physical location to work this out was important. Creating truly cross-functional teams couldn’t happen over Skype alone. DevOpsiCon was born to facilitate this transition. DevOpsiCon! Buy-in wasn’t immediate throughout the firm. Teams were updating legacy systems throughout the company and some were more focused on work than enablement. Joan: “The first one was a little bit sneaky. The next one was in Manchester and that one was a little less sneaky.” The discusses the importance of investment in enablement. This allows the feature teams to focus on the features they were actually building instead of all the underlying infrastructure. Joan: “Having them build everything they need is not realistic.” The fact that Meltwater has offices all over the globe makes any wholesale shift of company culture difficult. The discusses the need for face-to-face interaction to facilitate change. Gene: “There are these events like DevOpsiCon where we solve the problem by bringing a broad set of people together.” DevOpsiCon has grown beyond just developers. Product, UX, , and even sales have ed the event to help build relationships and give insight. Jessica: “That is very DevOps in the sense that DevOps says that you need to take these concerns that cannot be separated…and you can’t put those responsibilities on different teams and make them fight.” Unconference The discusses the value of DevOpsiCon as an unconference. Attendees collectively set the agenda on each day of the event. Gene: “That format has been so much fun and created so much value.” Gene: “The event becomes the conference you didn’t know you needed at the start. It adapts collectively to what the organization needs at that moment.” Ongoing Transformation Gene discusses how allowing teams the freedom to experiment can yield results that a top-down structure could not provide. The talks about the structure of mission, framework and teams. Joan: “By keeping things loosely coupled, it gives teams a lot more freedom to make the technology choices that are best for them.” Ownership Challenges The discusses the ownership challenges of moving from the datacenter to the cloud specifically and large enterprise changes more generally. The investment in enablement is critical. Joan: “There’s very much a not built here mentality that can take place.” Gene: “Software can benefit from being owned by many people.” The talks about overhead costs to both software and human changes. Gene talks about the challenges of moving to a full mission responsibility model. Gene: “You need to find efficiencies more effectively than you’ve ever had to find efficiencies before.” So! Has It Worked? Gene: “Oh wait, you’re looking to me for an answer?” The discusses the results of the ongoing DevOps transformation at Meltwater. The six month process for production changes has transitioned to a constant stream. Beyond the productivity, it has also been a quality of life improvement for the employees. Gene: “We’ve got a Slack channel for all the production changes and it is constant activity in it all week long of changes going out.” Joan: “We’re now getting hundreds of features out every six months to our customers.” The discusses the ways in which transformation is, or should be, a constant process. The change goes on. Find out more about Meltwater, their DevOps transformation, and the process of an unconference on their blog. Episode art by Evelyn Kerr.
