Resilience Testing
Resilience testing is the practice of verifying that your system handles failures gracefully. This covers more than chaos engineering — it includes unit-level tests for circuit breakers and retry logic, integration tests that simulate dependency failures, and chaos experiments that inject real failures into running systems. This guide covers the
Chaos Engineering
Chaos Monkey is the tool that started chaos engineering. Netflix built it in 2011 to randomly terminate EC2 instances during business hours — forcing engineers to build systems that assumed any server could disappear at any time. The open-source version runs on AWS and Spinnaker. For Kubernetes, Chaos Mesh or
SRE
Chaos engineering is the practice of intentionally breaking production systems to find weaknesses before they find you. Done wrong, it's just causing outages on purpose. Done right, it's a systematic method for building confidence in your system's resilience. The difference between chaos that helps
Testing
Chaos engineering and SLO management seem to be in conflict. SLOs protect reliability commitments. Chaos engineering deliberately breaks things. How do you test resilience without burning your error budget and violating your SLAs? The answer is planning — scoping experiments to stay within budget, baselining before you inject faults, and defining
Chaos Engineering
Chaos engineering without SLOs is just breaking things. You inject failures, watch dashboards, and write post-mortems. Chaos engineering with SLOs is different — it's a structured way to answer a specific question: "Does my system maintain its reliability commitments under real-world failure conditions?" This guide
Chaos Engineering
Chaos engineering is the practice of deliberately introducing failures into a system to find weaknesses before they cause incidents. The core idea: if you run controlled experiments that break things on purpose, you discover fragility in a controlled way rather than during a real outage. Netflix popularized it with Chaos
Testing Strategy
Chaos engineering is the practice of deliberately injecting failures into a system to verify it behaves correctly when real failures occur. Without observability, chaos experiments are blind — you inject a fault and cannot tell whether your system degraded gracefully or silently failed. Combining chaos engineering with structured observability turns experiments
Chaos Engineering
Chaos engineering without measurement is just breaking things. The metrics that matter are: blast radius (how much of your system was affected), MTTR (how long it took to recover), steady-state deviation (how far metrics drifted from baseline during the experiment), and detection time (how long until your monitoring noticed)
Chaos Engineering
Your microservices work in staging. They fall over in production. Chaos engineering is the practice of intentionally injecting failures to find weaknesses before users do. This guide covers two tools — Netflix Chaos Monkey (for instance/pod termination) and LitmusChaos (for Kubernetes-native chaos) — with a focus on meaningful experiments, not
Chaos Engineering
Kubernetes introduces a new class of failure modes that traditional testing misses: pods evicted under memory pressure, nodes drained during rolling updates, network policies blocking inter-service traffic, readiness probes misconfigured. Chaos engineering in Kubernetes targets these specifically — testing that your workloads survive the infrastructure events that Kubernetes itself causes.
Chaos Engineering
Chaos engineering is the practice of deliberately introducing failures into a system to find weaknesses before they cause real outages. Netflix invented the term and the tooling (Chaos Monkey). The core idea is simple: if your system will eventually fail, find out now under controlled conditions rather than during a
Testing
Distributed systems fail in ways you don't expect. Chaos engineering is the practice of intentionally introducing failures into your system to discover weaknesses before they cause production incidents. For microservices, it's not optional — it's how you gain confidence that your system actually works under
