What Is sFlow? A Guide to Sampled Flow Monitoring

What do you do when the switch carrying most of your traffic is the one device that cannot tell you what is on it? On high-speed core and data centre links, full flow export pushes device CPU past a comfortable line, so the export gets switched off and the busiest segment quietly becomes the least visible one. sFlow was built for that exact situation.

Ai4 2026: Measuring AI spend is solved. Now it's time to prove its worth.

CloudZero had a full team on the ground at Ai4 in Las Vegas during the first week of August 2026. The team included CTO Erik Peterson, who spoke on a panel about AI cost economics. The same problem surfaced everywhere we went: teams can see what they’re spending, but not whether it’s working. DIY cost tooling that fails time and time again, agent sprawl, and a widening gap between finance and engineering kept coming up throughout the week.

What are AI tokens? The unit your AI bill is written in

AI tokens are the small chunks of text, roughly four characters or three quarters of a word each, that language models read and generate. Every prompt and every response is measured in tokens, and AI providers bill per million of them. That makes the token the base unit of AI spend: 1,000 tokens is about 750 words, and every AI feature you ship is a token meter running.

What is AI ROI? Definition and why it matters

In 2025, 85% of organizations increased AI investment, and 91% plan to do the same this year, according to Deloitte. Despite continued spending, however, ROI lags behind, with just 6% seeing payback within one year. While AI use cases tend to have a longer payback period, often in the 2-4 year range, companies can’t afford to keep spending money without some measure of its practical impact both immediately and over time.

Shipped: Get anywhere in CloudZero with a keystroke

That means there’s no clicking through the nav and no scrolling to find what you already know the name of.

Introducing the Flyway MCP Server: governed database change, now available to your AI coding assistant

AI coding assistants have changed how fast application code gets written. Copilot, Cursor, Claude Code, and agentic tools built on top of them can generate a working feature in minutes. But none of them know your database's history. They don't know that a migration already renamed that column last sprint, that a policy forbids unqualified DELETE statements, or that the target environment has drifted from what your migrations say it should look like.

DORA in Practice: What Two Roundtables with Technical Leaders Revealed

The Digital Operational Resilience Act (DORA) has applied to financial organizations across the EU since January 2025 and is designed to strengthen their ability to withstand operational disruption. What the roundtables revealed was that although these financial organizations had completed extensive DORA planning exercises, this groundwork was not reliably translating into auditable operational control.
