Integration/E2E TestingLimitations in Measuring Platform Engineering with DORA metrics
Why DORA metrics can't evaluate a platform engineering team: they miss user-centric work, culture and documentation, and work best as one check beside qualitative measures.

Integration/E2E TestingThe wrong way to use DORA Metrics
Five ways DORA metrics get misused, from chasing the numbers over business goals to ranking teams against each other, and why a narrow set of measurements can hide real failures.

Integration/E2E TestingImprove Developer Velocity by Decentralizing Testing
Six ways centralized testing on staging slows developers down, how isolating each change in a shared cluster brings realistic tests back to the pull request, and five benefits of doing so.

How to Improve and Measure DevEx in Your Organization
Nine ways to improve developer experience, from standardized environments to incident management and developer autonomy, and how to measure the results with metrics and qualitative assessments.

How to Be an Effective Platform Engineering Team
Four challenges platform engineering teams face, from adoption versus completeness to vendor lock-in and proving value with DORA metrics, with lessons from Stitch Fix, Uber and Netflix.

Integration/E2E TestingWhy Testing Must Shift Left for Microservices
Why testing after development is too slow for microservices teams, and how smaller changes, faster feedback and isolated test versions on a shared cluster let developers find problems themselves.

Integration/E2E TestingHow to Fix Flaky Tests
How to deal with flaky tests: ban them, suppress them automatically, change what you expect of tests, or change the environment they run in, down to isolating each change on a shared cluster.
-
Integration/E2E TestingHow to Diagnose Flaky Tests
Why scale makes tests flaky, the usual causes from timing and test data to hidden bugs and external services, and how flaky tests wear down a team's trust in CI.

Integration/E2E TestingHow Microservices Communicate with Each Other
REST, gRPC and messaging through Kafka or RabbitMQ compared, then the hard part: testing those calls when every service depends on others, against real dependencies instead of mocks.

Ephemeral EnvironmentsScaling Environments with OpenTelemetry And Service Mesh
How request tenancy, carried by OpenTelemetry and routed by a service mesh such as Istio or Linkerd, lets dev, preview and test environments share one cluster, plus data and queue isolation.
