Stop Chasing Unicorns – ‘When it comes to ways of working, what do the companies that beat you in deals do better product, design, and engineering-wise?” Silence. “Do they do better discovery and research, ship higher quality work, run more experiments, kill bad decisions faster, retain passionate team members, or have a more effective org…

What is a service mesh? Why do you need a service mesh? And which is the best service mesh?
The infrastructure drives the app architecture A cloud native applications is typically designed as a bunch of little components that coordinate with each other over a network.

Rye Leafoot’s Guide to Elderwood: Aurel’s Reach
At the very heart of the Elderwood, Aurel’s Reach unfurls. Envision the central region of the Elderwood map: this is the Eldergrove, the verdant heart where Aurel’s Reach proudly stands.

Monoliths, Microservervices and Mainframes – Reflections on Amazon Prime Video’s Monolith Move – “The supposed development time difference between the two methods is not based on the technology itself, but the context in which you’re deploying it. The argument made by the table is tendentious. It’s based on comparing the worst case for ‘traditional’ application…

Generic Plan for a Starting a Platform Team in a Large Enterprise On Friday, I had a discussion with someone just starting to think about how they’d put a platform in place at their very large organization.

🗂 Link: Why would anyone need Cloud Foundry when we have Kubernetes? Um, ‘cos K8s is really hard!
Daimler’s Thomas Müller, platform architect, spoke this morning at the summit about his company’s migration from IBM WebSphere to Pivotal Cloud Foundry (PCF) and illustrated another point, that the typical enterprise has more to worry about than K8s support.

Dealing with or hiding from stupid business culture in their org. Getting permission to try new things. Testing code, automation to avoid legacy traps. More scalable architecture for distributed apps, new types of…

🗂 Why Do We Need Architectural Diagrams?
> In practice, most stakeholders are not interested in detailed diagrams, but rather in one or two high-level diagrams which reflect the modularity and boundaries of the system. Beyond these, for a deeper understanding, the code should be the source of truth, which in most of the cases only developers are interested in. www.infoq.com/articles/…

Link: Add It Up: FaaS ≠ Serverless

Link: Think in Products, Not Projects
“In a high level, projects are local optimization efforts. We get a group of people who create new (or improve existing) functionality for our customers and then we pass that onto a team that has no idea why the change was made and how this change was solutioned/implemented. Very often, the quality is low and…
