Day 167: Automated Root Cause Analysis - Finding the Needle in the Haystack
The post outlines a hands‑on project to build an intelligent root‑cause analysis (RCA) platform that automatically traces incidents across distributed microservices. By ingesting massive log streams, constructing dependency graphs, and detecting temporal event patterns, the system can pinpoint the exact failure source within seconds. The tutorial includes source code access and a free interview pack for engineers preparing for distributed‑systems roles. The goal is to turn a traditionally manual, hours‑long debugging process into an automated, real‑time capability.
Microservices Platforms - Part 8: Getting Started with Platforms
The eighth installment of the Microservices Platforms series examines why up to 70% of platform‑engineering teams under‑deliver and outlines steps to improve outcomes. Drawing on the author’s QCon talk and a New Stack study, the piece highlights common pitfalls such...
Day 61: Circuit Breakers for Handling Component Failures
The post details the integration of circuit breakers into a multi‑region log processing pipeline, wrapping outbound calls to Kafka, Redis, and PostgreSQL. It introduces a state‑machine‑driven failure detector with configurable thresholds, timeouts, and half‑open probing. Fallback mechanisms ensure continuous ingestion...
Review Is The Bottleneck Now: How We Let AI Approve Pull Requests (Safely)
Software firm introduced Diff Vader, an AI‑driven reviewer that auto‑approves low‑risk pull requests, shifting senior engineers’ focus to high‑impact changes. The system grades PR risk based on findings, not line count, and routes only safe changes to the bot. A...
SRE Weekly Issue #519
The latest SRE Weekly issue spotlights BigPanda’s new AI‑driven engine that predicts which code changes will trigger incidents, positioning it as a preventive tool for SRE teams. The newsletter curates several thought‑leadership pieces, including a critique of AI‑generated post‑incident reviews,...

Reading Observability Tools? That’s a Robot’s Job
At O11yCon, the author argued that observability is no longer read by humans but by AI agents, making traditional dashboards obsolete. The talk highlighted how metrics and logs were designed for human intuition, while traces provide the structured, queryable data...
You Can't Fix What You Can't See
The post outlines six observability patterns essential for debugging microservice architectures, drawing on the Microservices Patterns book by Chris Richardson and real‑world implementations at Netflix, Uber and Discord. It explains why monolithic debugging is simple compared to the fragmented logs,...
Day 60: Multi-Region Replication for Log Data
The lesson walks through building a multi‑region log pipeline using Kafka MirrorMaker 2 to replicate events across two simulated regions. It implements an active‑active topology, conflict‑resolution via idempotency keys, region‑aware API routing, and end‑to‑end monitoring of lag, throughput and divergence. The...
Urgent Salesforce Security Update Will Break Your CI/CD Unless You Act Now
Salesforce announced a major security update to the Salesforce CLI that will redact sensitive credentials—access tokens, passwords, and auth URLs—from standard command outputs and JSON responses. The changes go live in the release‑candidate today and become mandatory in the production...
The CTO Checklist for AI-Ready IT Operations in 2026
AI is moving from a side project to the core of IT operations, but most enterprises still rely on fragmented toolchains that dilute its impact. The article argues that true AI‑ready operations require a single, connected platform that unifies service...
