Trace without traces

A customer emailed on a Tuesday: checkout hung for ten seconds. I opened our tracing tool, punched in the time window, and got nothing. The trace was sampled out. We keep 1% of traces, like most shops with real traffic do. The one request that actually mattered was in the 99% we threw away. I spent twenty minutes admiring our observability stack before admitting it couldn’t answer a first-grader’s question: what happened to this person? Here’s what I know now.

Cloud repatriation strategies: From public dependency to hybrid flexibility

For years, "move everything to the cloud" was the default. But the economics have shifted. Join Russell Smith to explore why enterprises are reconsidering their cloud strategies, and how modern private cloud platforms are changing the game. We'll cover the real costs of public cloud lock-in, achieving feature parity without the price premium, and how to navigate today's hardware constraints, especially if you've got existing infrastructure assets that can still deliver value.

ACP vs MCP: What's the difference for agentic coding?

An AI coding agent holds many conversations at once. Not only is the user prompting it, the agent also talks to the IDE, showing diffs and asking before it touches a file. At the same time it talks to tools, pulling a failing build or querying a database. Two open protocols standardize those conversations. This guide compares ACP vs MCP in practical terms: what each protocol does and when each applies. ACP (Agent Client Protocol) connects a code editor to an AI coding agent.

Walkthrough: Puppet System Hardening Assessment

Is your infrastructure as secure as you think it is? In this walkthrough, see how aSystem Hardening Assessmenthelps organizations identify security gaps, uncover configuration risks, and prioritize remediation efforts across critical systems. You'll learn how teams can evaluate their environment against security best practices, gain visibility into potential vulnerabilities, and take actionable steps to strengthen their overall security posture.

The golden path: security that works because it's the easy path

A golden path for dependency management isn't a policy document – it's a preconfigured private registry with upstream proxies covering every ecosystem your teams use, set as the default. Developers don't opt into security; they get it automatically by using the standard toolchain. The alternative is teams configuring their own controls, producing inconsistent postures and compounding risk across the org. If the secure path requires extra steps, developers will route around it. Make it the easiest option and the policy enforces itself.

How Liftoff cut costs by 87% and latency by 75% with HAProxy

Liftoff, a mobile advertising company, processes 1.5 trillion bid requests every month. Their platform touches 275 million unique devices daily across 150 geographies. At that scale, the proxy layer is a core part of the business. For years, Liftoff relied on a managed enterprise proxy vendor. It worked, until it didn’t.

Designing the New Workloads Dashboard for Rancher

To meet community demand, we have restored the global workload overview in Rancher Manager. After previously removing the feature due to performance constraints, we prioritized user feedback and rebuilt it from the ground up. Powered by a new, optimized API, the updated UI is both highly scalable and resilient.
