Observability: When Security Intercepts Traffic Before the Application
Sometimes the system “breaks” even before entering the application. This case is about how the security layer completely obscures the behavior of the backend. Observability
Architecture and Infra
Architecture and Infra on ThecoreGrid covers the foundations of designing and operating scalable, reliable systems at BigTech level. This category brings together system design and infrastructure practices: distributed architectures, highload patterns, cloud-native platforms, and core layers such as compute, networking, and storage. We focus on real engineering decisions — how to balance reliability, performance, cost, and long-term system evolution. Topics include Infrastructure as Code, Kubernetes, multi-region deployments, traffic management, and platform design. Content is grounded in production experience: incident post-mortems, large-scale migrations, and lessons from operating infrastructure under heavy load. Instead of abstract theory, you get practical trade-offs, proven patterns, and insights drawn from real-world systems. Architecture & Infra is built for architects, backend and platform engineers, DevOps teams, and SREs responsible for complex distributed systems and mission-critical infrastructure.
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.
Edge AI on Kubernetes without Loss of Consistency
Edge AI Kubernetes as a unified platform: how to scale the edge without fragmentation and maintain control over distributed infrastructure.
ParaQAOA Accelerates QAOA for Max-Cut
arXiv is the largest open preprint repository (since 1991, under the auspices of Cornell), where researchers quickly post working versions of papers; the materials are publicly accessible but do not undergo full peer review, so results should be considered preliminary and, where possible, checked against updated versions or peer‑reviewed journals.
Hugging Face inference selection for agent systems
Hugging Face inference as a fallback for agent systems: hosted vs local, trade-offs, architecture, and deployment via llama.cpp.
Mid-path Network Analysis through A/B Route Comparison
Mid-path network analysis through A/B comparison reveals bottlenecks in interconnection, hidden behind traditional metrics of latency and throughput.
Edge error handling without failure data
Edge error handling: why CDN failures without logs block diagnostics and how to build observability for analyzing such incidents

OpenShift Virtualization 4.21: how to simplify VM management and reduce complexity in hybrid cloud
Tracing in the actor model without degradation through Envelope
In actor systems, there is no built-in channel for trace context. Discord solved this without changing the architecture and without stopping production.
