Modern software runs on open source. In fact, “free” and open source software generates more than $500 billion in annual value in the U.S. alone and an estimated $8.8 trillion in total global value. For most...

OpenTelemetry has become the de facto standard for collecting and exporting telemetry data across cloud native systems. Its success has been driven by strong community collaboration, a clear specification, and a growing ecosystem of language-specific SDKs...

Observability Day has become a cornerstone gathering for the cloud native observability community. The event evolved from FluentCon at KubeCon Europe 2022 in Valencia and Open Observability Day at KubeCon North America 2022, bringing together maintainers...

Ten years into CNCF’s journey, one thing hasn’t changed: we still rely on real signals—open source contributions, real-world deployments, and community energy—to understand where we’re headed. Cloud native is now invisible infrastructure, quietly powering our everyday...

As cloud-native architectures continue to mature, observability has become a foundational requirement rather than an optional add-on. According to the Cloud Native Computing Foundation, OpenTelemetry continues to grow its contributor base and remains the second highest...

The challenge Managing millions of concurrent connections during global events like flash sales and online voting requires resilient, scalable observability. At STCLab, we operate platforms including a bot mitigation platform and traffic management platform that support...

Ambassador post originally published on Medium by Dotan Horovits Microservices have been with us for nearly two decades, but it’s still far from easy to develop at scale, in a polyglot environment. The Dapr project, the...

Stepping into my first KubeCon + CloudNativeCon, held this year in November in Atlanta, Georgia, felt like entering a world I had been following from afar for years; a world full of brilliant minds, bold ideas,...

Modern applications rarely live in a single place anymore. One organization’s application footprint was spread across AWS, Azure, and GCP, with some workloads still running on-prem. This multi-cloud approach gave them resilience and flexibility, but it...

A platform engineer’s guide to developer buy-in Originally published on the author’s personal blog, whitneylee.com As platform engineers, we want the holistic system insights that instrumented code can give us –  yes, please. With code-level insights...

Ambassador post originally published on Medium by Dotan Horovits “Cloud Native Computing Foundation (CNCF) is a new open standardization initiative recently formed under the Linux Foundation with the mission of providing standard reference architecture for cloud native applications...

When people talk about cloud-native observability, the conversation usually revolves around applications, containers, and microservices. However, under those layers lies an equally critical foundation: The physical data center. Servers, storage systems, and networks ultimately host every...

Ambassador post originally published on Medium by Dotan Horovits It’s about time open observability had its own industry-wide, vendor-neutral event. This year, the Cloud Native Computing Foundation (CNCF) finally made it happen with the inaugural Open Observability Summit, bringing...

In today’s rapidly evolving AI landscape, effectively monitoring and debugging AI Gateways has become a critical challenge. This article shares my complete experience through the LFX Mentorship program, where I added OpenTelemetry distributed tracing support to...

DevOps is a way of working that reduces waste. It uses smart tools and practices to build, test, and ship software faster. It makes teams quicker, systems stronger and problems smaller when done right. It’s not...

LLMs and AI are everywhere these days. Everyone wants to build the next big thing, ship it fast, and maybe even cash out and chill for the rest of their lives. The problem? Most open source...

Learn how to test complex asynchronous workflows in cloud native applications using OpenTelemetry for context propagation and Istio for traffic routing. Explore cost-effective approaches to isolate test environments without duplicating infrastructure. Introduction Asynchronous architectures have become...

As OpenTelemetry adoption has exploded, so has the volume of telemetry data moving through modern observability pipelines. But despite collecting more logs, metrics, and traces than ever before, teams are still struggling to answer the most...

On May 29th, 2025, I wrapped up my mentorship with Prometheus through the Linux Foundation Mentorship Program. My project focused on understanding how Prometheus handles OpenTelemetry resource attributes and how that experience could be improved for...

Building upon our previous analyses, we continue to monitor trends and technologies that resonate with developers and end users. Take a look at our past timeframes from our blogs.  Here are the main takeaways I see...
