Rethinking developer productivity in the age of AI

Dec 10, 2025 By Cortex In Cortex
For decades, engineering leaders have struggled to measure the productivity of their developers. Metrics such as number of PRs merged, lines of code changed, hours worked, and tickets closed were always flawed. They incentivized the wrong behaviors and ignored code quality and best practices. Ultimately, they were the perfect formula to make Goodhart's Law a reality. Measures became targets, which meant they ceased being good measures.

CI/CD for Go Microservices on Scaleway Kubernetes with CircleCI

Dec 10, 2025 By Olususi Oluyemi In CircleCI
Development teams depend on microservices to build, deploy, and scale features independently. Microservices have become the backbone of modern, scalable applications. Scaleway’s managed Kubernetes service (Kubernetes Kapsule) offers a powerful, cost-effective platform for running containerized workloads in the cloud. It’s a great fit for startups and solo engineers who want to focus on shipping features, not managing infrastructure.

Cortex Wrapped 2025: The Year of AI Excellence

Dec 3, 2025 By Cortex In Cortex
Every December, Spotify launches its infamous Wrapped campaign, which sends millions of users into a frenzy about their listening habits. They become pseudo data scientists and analyze how frequently they listen to their guilty pleasures, their kids' terrible playlists, or the music they love that nobody else has heard of yet. We love this tradition, so we're bringing it to Cortex.

Cortex and Rootly partner to help teams turn incidents into continuous improvement

Dec 2, 2025 By Tony Marino In Cortex
For many engineering teams, an incident is a chaotic, all-hands-on-deck event. Once the incident is resolved, everyone returns to their regular work and the valuable lessons from the incident are often lost. The result is a cycle of repeated failures and engineer burnout, where incidents are something to be survived, not learned from. At Cortex, our mission is to help engineering organizations build a culture of continuous improvement.

End-to-End Testing for Microservices: A 2025 Guide

Nov 30, 2025 By Alin Dobra In Bunnyshell
End-to-end testing has always been a double-edged sword - even more so in the world of microservices. On one hand, E2E tests are critical for validating that all services work together seamlessly in real user flows. On the other hand, many experts warn that heavy reliance on end-to-end testing in a microservices architecture can create a "distributed monolith," slowing down deployments and undermining the very agility microservices promise. There's truth to that: if done poorly, E2E tests can become brittle, flaky, and a bottleneck that reduces your deployment frequency.

10 platform engineering tools your devs will thank you for

Nov 26, 2025 By Cortex In Cortex
Modern engineering teams are shipping more services, managing more complex infrastructure, and moving faster than ever. But this velocity often comes at a cost to the developer experience. Engineers are frequently bogged down by infrastructure complexity, inconsistent tooling, and a lack of clear standards, which leads to cognitive overload and slower cycle times.

The engineering leader's guide to AI tools for developers in 2026

Nov 25, 2025 By Cortex In Cortex
The holiday shopping season is a familiar ritual for many. We spend hours researching the best deals, comparing features, and reading reviews to make sure we’re investing in the right things. As we all come to grips with the fact that 2026 is right around the corner, engineering leaders are doing the same thing, but largely in response to the explosion of AI developer tools.

The most important question to ask in the build vs. buy debate

Nov 20, 2025 By Cristina Buenahora Bustamante In Cortex
Every growing engineering organization eventually faces the seemingly impossible decision between building a custom solution or buying one off the shelf. It’s a debate that often (and incorrectly) ends by choosing whichever option is less expensive. However, it’s become clear that solving the build vs. buy puzzle boils down to understanding what you want to be good at and whether your internal build is actually unique.

Get more from your AI chief of staff with these prompts for engineering leaders

Nov 19, 2025 By Cortex In Cortex
Engineering leaders face a constant barrage of questions that pull them away from strategic work. A team lead asks about scorecard compliance. A PM wants a status update on a migration. Someone needs incident trend data for a quarterly review. Each question is reasonable. Each requires context switching, digging through dashboards, or pinging someone on your team for a report. What if you could just ask?

Modern Service Architecture for High-Velocity Operations

Modern Service Architecture for High-Velocity Operations

Nov 19, 2025 By OpsMatters In OpsMatters
Modern service architecture supports organizations that target sustained velocity, predictable delivery cycles, and scalable global operations. Cloud-native platforms, microservices patterns, and distributed execution models now anchor these environments. Modern service architecture emphasizes modularity and flexibility, which contrasts with traditional monolithic approaches. The 2025 Gartner Magic Quadrant for Cloud-Native Application Platforms identifies AWS, Red Hat OpenShift, and Heroku as leaders because they strengthen developer experience, platform engineering, and security.
