Virtual users (VUs) are the simulated humans that hit your system during a load test. They’re the load. Where real users come from browsers and apps, VUs come from a test harness. JMeter threads, k6 worker goroutines, Locust greenlets. Each VU sends requests, waits for responses, sometimes pauses (“think time”), and repeats. Aggregate enough VUs and you get traffic that looks like a real audience.

Customer data ingestion is the process of collecting customer records from CRM, ERP, product, support, and file-based sources, validating them, and routing them into the systems that power onboarding, reporting, and activation. For B2B platforms, a good approach is a tenant-safe pipeline that can land history, sync ongoing changes, and deliver trusted records quickly.

Modern infrastructure transformation should accelerate innovation — not add complexity. As organizations modernize to support mission-critical workloads, hybrid architectures, AI data activation, and third-party environments, they need flexibility, visibility, and trust. That’s why Hitachi Vantara is simplifying infrastructure acquisition and management by delivering an outcome-driven experience for the data center.

WebSockets are the right protocol for production AI chat. But that fact doesn’t prevent the failure most teams hit first. An enterprise load balancer closes the idle connection at 60 seconds during a tool execution wait. Your reconnect logic fires in under a second, the agent keeps running server-side, and the client receives nothing from the gap. No tokens, no tool call results, no context. The reconnected socket has no view of what happened while it was down.

A streaming transformation is a continuous operation that processes events as they arrive, applies logic in real time, and emits transformed results immediately—without waiting for batch jobs to complete. In Apache Flink, a streaming transformation runs continuously, reacting to each event from a stream. This enables real-time data transformation directly on live data.

The 2027 S/4HANA deadline still looms large in the minds of SAP customers, but at this year’s SAP Sapphire event, SAP worked to move the conversation beyond cloud migration alone. Instead, they introduced a broader redefinition of what it means to be an “Autonomous Enterprise.” At the center of this new Autonomous Enterprise strategy is agentic AI. SAP envisions the future enterprise as one that can leverage its business data to power agents across its ERP applications.

Every QA leader has faced the same conversation. Leadership asks: "What are we getting for our automation investment?" And the honest answer is often some version of "we're faster than we used to be" without hard numbers to back it up. That gap between intuition and evidence is where automation programs get defunded. Not because they are not delivering value, but because the value was never quantified in terms finance teams understand.

Traditional Customer 360 architectures were perfectly adequate for the era of quarterly reports and static marketing segments. They successfully pooled data from CRMs, transaction logs, and support platforms to build a unified profile. But for GenAI-powered applications? Yesterday's architecture is a massive bottleneck. Here is why legacy systems are breaking down under the demands of modern AI, and how the architecture is forcing a shift to real-time data.

People often imagine that to provide a cloud service for a piece of open source software is a simple matter of packaging up the open source and putting it in Kubernetes. We knew when we set out to build Confluent Cloud that a true cloud-native offering of Apache Kafka as a service would be much, much more than that.

For everyone in QA inside the Atlassian ecosystem, the last few months have made one shift obvious. AI is changing how software gets built, and the quality function must change with it.
