Chaos Engineering vs. Traditional Testing: What's the Difference? | Resilience Testing | Harness

Stop treating system outages like surprises and start preparing for them. While traditional software testing is the bedrock of development, using unit, integration, and regression tests to verify that code meets specific requirements, it only accounts for what we expect to happen. Chaos Engineering takes a different approach by shifting the focus from bug prevention to system resilience. Instead of asking "does this work?", Chaos Engineering asks "how does this survive?" by injecting real-world turbulence like network latency or pod failures directly into production-like environments.

RTO and RPO in Disaster Recovery Explained | Resilience Testing | Harness

Struggling with disaster recovery planning? Learn the simple difference between RTO and RPO, the two most important metrics every developer, DevOps engineer, and SRE must understand. RTO (Recovery Time Objective) tells you exactly how long your systems can stay down before it hurts your business. RPO (Recovery Point Objective) shows how much recent data you can afford to lose in an outage.

What Does Load Testing Measure? (Top 5 Performance Metrics) | Resilience Testing | Harness

Before you deploy, you need to know if your application can handle real-world traffic. In this video, we break down the 5 essential load testing metrics: Response Time (latency), Throughput (requests per second), Error Rates (system stability), Resource Utilization (CPU/Memory bottlenecks), and User Concurrency. Whether you're into Software Engineering, DevOps, or SRE, understanding these System Design fundamentals is the only way to prevent server crashes and ensure Software Scalability.

Why Your CI/CD Pipeline Needs Deterministic Test Automation

Most CI/CD pipelines have a testing problem that nobody talks about enough. The pipeline runs. The tests pass. The build deploys. And then something breaks in production that the test suite had no business missing. Not a flaky test, not an infrastructure issue. A real gap in coverage that existed quietly for weeks before it mattered. Here's the thing: the pipeline itself is usually fine. The problem is what's feeding into it.

AppSignal x Hatchbox: Affordable Hosting, Full Visibility

Affordable hosting has always been a puzzle. Heroku made deploying Rails apps simple, but with Salesforce at the helm, active development has stalled. Many developers are left wondering what comes next, locked into a platform that is no longer moving forward. Chris, the founder of GoRails, felt that same frustration. That is why he built Hatchbox. Hatchbox handles your deployments, runs on servers you own, and keeps costs predictable. No dyno management, no add-on sprawl.

Secrets Management: Get Credentials Out of Your Netdata Configuration Files

If you’re running Netdata collectors that connect to databases, APIs, or other authenticated services, there’s a good chance you have passwords sitting in plain-text configuration files right now. It works, but it’s the kind of thing that makes security teams nervous and makes credential rotation painful. Every password change means editing config files and restarting collectors.

From GIGO to Digital Twin: How DCIM G2 Cleans Up Your Data Center Data Quality

“Garbage in, garbage out.” Everyone who has ever worked in computing or other data-adjacent fields has heard this adage at least once. This phrase or acronym (GIGO) reflects the fundamental concept in both computing and data governance that the quality of your data is the critical determinant of successful results in any system, regardless of whether your focus is IT or OT.
