In 2020, the enterprise development market shifted significantly towards cloud-native development, embracing microservices architectures with Kubernetes as the dominant platform, largely supported by open source software. The DevOps Pulse survey revealed that a significant portion of infrastructure is now cloud-based, with open source tools like the ELK Stack, Prometheus, Grafana, and Jaeger becoming standard for log management, monitoring, and tracing in Kubernetes projects. Despite their widespread adoption, challenges remain in achieving effective observability, particularly with Kubernetes architecture and scaling open source tools. The OpenTelemetry project aims to address these issues by standardizing data collection methods for telemetry data, enhancing portability and queryability. Companies like Logz.io are capitalizing on these trends by offering scalable SaaS solutions that integrate open source telemetry tools, helping organizations like ZipRecruiter improve performance and scalability while leveraging existing skill investments. The future of cloud-native observability is closely tied to open source tools, which continue to evolve through global community collaboration and vendor innovation, promising improved software reliability and resiliency.
