Kubernetes

Progressive Delivery

  • (2024) Iter8 [GO CONTENT] [ADVANCED LEVEL] 🌟🌟🌟🌟 [ENTERPRISE-STABLE] — A Kubernetes-native release validation and progressive delivery tool. Iter8 enables automated canary testing, A/B testing, and SLO evaluation. It coordinates traffic shifting using Service Meshes or Gateways, evaluating metrics from Prometheus and metrics-server to automate rollbacks or promote stable microservice builds.

Continuous Delivery

Feature Management

Reliability Engineering

  • (2021) devops.com: How SREs Benefit From Feature Flags [COMMUNITY-TOOL] — Investigates the role of feature flags in risk mitigation. Demonstrates how isolating application deployment from runtime feature activation enables SREs to instantly disable buggy paths without executing a full application rollback.

SLO Validation

REST APIs

Observability

Monitoring

SRE Fundamentals

  • (2021) circonus.com: Monitoring for Success: What All SREs Need to Know [COMMUNITY-TOOL] — Examines monitoring frameworks focused on business outcomes rather than raw resource metrics. Guides SREs on setting up context-rich telemetry pipelines that prioritize application-level user experience over physical host utilization.

Service Level Objectives

Community Events

  • (2021) SLOconf [COMMUNITY-TOOL] — Official site of SLOconf, the premier developer conference and community space focused entirely on Service Level Objectives, error budgets, and reliability-driven service platforms.

Declarative Standards

  • (2021) ==OpenSLO specification 🌟== 1496 [YAML CONTENT] [ADVANCED LEVEL] 🌟🌟🌟🌟🌟 [DE FACTO STANDARD] — The vendor-agnostic OpenSLO specification defines standard YAML schemas for declaring SLOs, SLIs, and error budgets. In 2026, it remains the standard for orchestrating declarative system health models inside GitOps automation.

GitOps

Google Best Practices

  • (2020) sre.google: The Art of SLOs [ADVANCED LEVEL] [DOCUMENTATION] [COMMUNITY-TOOL] — Google's structural guide to defining user-centric Service Level Indicators (SLIs) and Service Level Objectives (SLOs). Features processes to prevent metric fatigue and map indicators directly to consumer utility.

Site Reliability Engineering

Root Cause Analysis

Operations

Platform Engineering

Organizational Design

  • (2022) devops.com: SRE Vs. Platform Engineering: Whats the Difference? [COMMUNITY-TOOL] — Differentiates the core focuses of Platform Engineering and SRE. Analyzes how SRE teams protect application reliability, while Platform Engineering optimizes developer velocity by packaging tools into Internal Developer Platforms (IDPs).
