Unit Testing in CI/CD: How to Accelerate Builds Without Sacrificing Quality | Harness Blog

Smart test selection, parallel test runs, and intelligent caching can all speed up builds without sacrificing code quality. Fast, focused, and separate unit tests are very important for quick development. They give you feedback right away and make it easier to refactor with confidence. Unit tests are a quick and cheap way to find logic errors, but they can't check how different parts work together. For full coverage, use them with integration tests and end-to-end tests.

When ConfigMaps Hit Limits: Migrating to CRDs

Over the past few years, Kubex has evolved from a cloud optimization product into a Kubernetes-centric solution, shifting its focus from cost and waste visibility to fully automated resource optimization. As that evolution happened, one of the earliest design decisions we had made began to show its limits: how the product was configured.

How to run checks on internal services with Grafana Cloud Synthetic Monitoring

Many critical services run inside private networks, where traditional monitoring tools and practices can’t offer full visibility. This makes it difficult to validate service availability and performance before problems impact your users. Synthetic Monitoring — a Grafana Cloud solution that helps you proactively monitor the performance of your applications and services — addresses this gap with a feature known as private probes.

VictoriaMetrics at FOSDEM, Cloud Native Days France, and CfgMgmtCamp Ghent

Last week, members of the VictoriaMetrics team, including myself, spoke at three very different but equally important community events: FOSDEM in Brussels, Cloud Native Days France in Paris, and CfgMgmtCamp in Ghent. Each event drew a different crowd with its own expectations, making them a good way to see where open source observability stands today and how VictoriaMetrics is adapting to real-world needs. The talks we gave were snapshots of the problems we are actively working on.

The Future of StatusPal: Classic and Next

Over the past years, StatusPal has been the product teams rely on to communicate clearly during incidents and maintenance. It’s the product our customers use today, and it remains central to how we support critical communication. We want to share how we’re thinking about the future of StatusPal, what this means for the product you’re using today, and how a newer version we’re building fits into the picture.

Kubernetes Network Observability: Comparing Calico, Cilium, Retina, and Netobserv

Calico, Cilium, Retina, and Netobserv: Which Observability Tool is Right for Your Kubernetes Cluster? Network observability is a tale as old as the OSI model itself and anyone who has managed a network or even a Kubernetes cluster knows the feeling: a service suddenly can’t reach its dependency, a pod is mysteriously offline, and the Slack alerts start rolling in. Investigating network connectivity issues in these complex, distributed environments can be incredibly time consuming.

3D Printing Explained: Essential Guide for Businesses in 2026

Most business owners have seen 3D printing - usually in some video where a machine slowly builds a plastic toy. That's where a lot of people stop paying attention. They think it's just for prototypes or hobbyist stuff. But companies are using this to fix real problems now. The expensive kind. Custom parts that used to take weeks? You might have them tomorrow. Want to test five different designs before committing? Make them all this week. Those months-long lead times? Not always necessary anymore.

Is a College Degree Still Worth It for Learning IoT and Emerging Technologies

Figuring out whether a college degree is still the smartest path for learning IoT and other fast moving tech fields can feel overwhelming. Bootcamps, online courses, and self guided learning seem to pop up everywhere, promising quicker paths into the workforce. At the same time, traditional universities continue to update their programs to keep pace with connected devices, AI, and automation. The truth sits somewhere in the middle. A degree is still valuable, but the reasons why have shifted.

Scaling Creative Output Without Sacrificing Quality

Scaling creative output often breaks when volume blurs what made the work recognizable. As calendars fill, small shifts in tone, visuals, and judgment start to stack up. In editorial terms, scaling means increasing volume and coverage without lowering standards. That only works when roles stay clear and each asset has a defined path to "done." More posts do not equal scalable content production. Scale comes from repeatable systems that protect brand consistency and quality control across busy weeks, staff changes, and multiple contributors.
