Graph-based remediation reduces pager alerts in MongoDB
How graph-based remediation automates MongoDB recovery and reduces pager alerts through state machine and pathfinding in a graph
SRE
SRE on ThecoreGrid focuses on engineering practices for running reliable, scalable, and observable systems in production.
We cover core Site Reliability Engineering principles, including SLI/SLO design, error budgets, incident management, and operational excellence in highload environments. Topics include monitoring, alerting, automation, capacity planning, and failure handling across distributed systems. We analyze trade-offs between reliability and feature velocity, as well as strategies for reducing toil and improving system resilience. Content is grounded in BigTech practices, including real incident post-mortems and lessons from operating systems at scale. You’ll find deep dives into observability, release engineering, chaos testing, and reliability patterns for cloud-native platforms. Instead of high-level overviews, the SRE tag delivers practical, production-focused insights for SREs, DevOps engineers, platform teams, and architects responsible for maintaining system stability and performance under real-world conditions.

DNS routing for gRPC eliminates thundering herd
DNS routing for gRPC: how changing the Route 53 policy eliminated the thundering herd and distributed the load across 121 million connections without errors
Azure IaaS security through defense in depth
Azure IaaS security is built as a layered system, where the failure of one control does not lead to the compromise of the entire platform. This is crucial for resilience against modern attacks that operate simultaneously across multiple fronts. The problem does not manifest immediately — until the classic “perimeter” model stops working. In the … Read more

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
Edge error handling without root cause data
Edge error handling without diagnostics breaks observability. An analysis of why errors without context block analysis and how this is addressed.
