Modern cloud-native architectures are composed of multiple microservices running across dynamic environments. Effectively diagnosing performance issues, bottlenecks, or failures requires comprehensive observability. For this, many organizations look to OpenTelemetry, which provides a standardized approach to capturing and analyzing telemetry data. Fir is Heroku’s next generation cloud platform , designed to offer more modern cloud-native capabilities with flexibility and scalability. It’s built on proven, open-source technologies. Traditional Heroku relied on proprietary technologies, which was appropriate at the time because high-quality open-source alternatives didn’t exist. But now, technologies like Kubernetes and OpenTelemetry are considered best-in-class solutions that are widely deployed and supported by a vast ecosystem. Kubernetes is at the core of Fir’s infrastructure, providing automated scaling, self-healing, and efficient resource management.…
