Kubernetes controller staleness cache control
How Kubernetes controller staleness affects system behavior and how version 1.36 addresses the issue through AtomicFIFO and resource version control
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.

pgBackRest future reshapes PostgreSQL backup strategy
pgBackRest remains a key tool for PostgreSQL backup, but changes surrounding the project raise questions about sustainability and support. A critical part of the stack relies on a small group of maintainers. pgBackRest has long been the de facto standard for PostgreSQL backup and recovery. It is widely used in production and integrated into data … Read more
