JUnit 5 Migration to a Monorepo with 1.25 Million Lines of Code
How to perform JUnit 5 migration in a monorepo: automated code transformation, OpenRewrite, and phased change architecture
DevOps
DevOps on ThecoreGrid focuses on building reliable, scalable, and efficient engineering workflows for modern production systems.
We cover practices and tooling that connect development and operations: CI/CD pipelines, infrastructure as code, automation, and platform engineering. The emphasis is on real-world production challenges — deployment strategies, environment consistency, observability, incident response, and system reliability at scale. We explore trade-offs between speed and stability, autonomy and governance, as well as team topology and ownership models. Content includes BigTech practices, incident post-mortems, and lessons from operating highload distributed systems. Topics span Kubernetes, GitOps, release engineering, monitoring, logging, and security in DevOps environments. Instead of basic tutorials, the DevOps tag provides deep technical insight and practical patterns for engineers, SREs, and platform teams responsible for delivering and operating complex systems with confidence and consistency.
ThecoreGrid Trend Report: AI platforms, Zero Trust, and the end of scaling at any cost
6-12 month IT trend analysis: why AI is becoming a runtime platform, security is shifting to Identity-First, and the industry is choosing efficiency
K3s on-prem Kubernetes via k0rdent and Proxmox
How to build K3s on-prem Kubernetes via k0rdent and Proxmox. Declarative approach, BYOT, and cluster management without manual assembly
Golden path platform without implementation traps
Why the golden path platform fails during implementation: an analysis of errors, templates, and metrics that truly show results.
Platform health through the lens of developer experience
How to measure platform health through developer experience, adoption, and toil, not just observability and uptime.
Platform engineering with Policy as Code without friction
Platform engineering with Policy as Code: how to embed governance in CI/CD and mitigate risks through CAPOC and automated policies.
Platform engineering metrics without telemetry
Platform engineering metrics without a baseline deprive teams of control. An analysis of the approach using the Kubernetes Secrets Manager and scorecard model.
When Security and Architecture Diverge, the System Pays
The connection between security and architecture breaks not in the code, but in the decisions. The analysis shows how systemic compromises turn into incidents.
Scaling Architectural Control: A Declarative Approach Instead of Manual Review
GenAI has accelerated code production, but has made consistency (alignment) a bottleneck. Manual processes can no longer keep pace, and the architecture begins to fragment. The problem does not manifest immediately — until the speed of change generation exceeds the organization’s ability to review them. Historically, control has relied on people: key experts in startups … Read more
Automation of Design System Specifications: How Uber Eliminated Documentation Drift Using AI Agents
When component specifications lag behind implementation, the team starts building the system based on assumptions. At Uber, this turned into a systemic, large-scale problem—and was solved through agent-based automation. The problem does not arise at the moment of writing specifications, but later—when the system begins to evolve faster than the documentation. The Uber Base design … Read more
