What is Chaos Engineering?
Chaos Engineering is a proactive approach to building system resilience by deliberately introducing controlled disruptions. These disruptions reveal weaknesses and behaviors under real-world conditions like high traffic, unexpected outages, or resource bottlenecks.

How does Chaos Engineering work?
Chaos Engineering turns unexpected failures into learning opportunities by running safe, intentional experiments. It’s about testing assumptions and improving reliability and follows a systematic process to generate actionable insights into system performance. This includes:
- Define Expectations: Start by identifying your system’s baseline behavior using metrics like latency, throughput, or error rates. This serves as your steady state.
- Hypothesize Outcomes: Predict how your system should respond under specific stressors.
- Inject Failures: Introduce conditions like service interruptions, latency spikes, or resource exhaustion to test resilience.
- Observe Behavior: Use monitoring tools to compare actual performance against expected outcomes.
- Refine and Repeat: Apply insights to enhance system design and iterate on experiments.
Steadybit simplifies every stage of this process, combining user-friendly interfaces with powerful automation to ensure safe, efficient experimentation.
The Objective of Chaos Experiments
The goal of chaos experiments is to identify and fix vulnerabilities before they impact users. These experiments help teams make informed improvements to their systems.
These experiments:
- Challenge Assumptions: Validate that your systems behave as expected under stress.
- Proactively Address Risks: Identify failure modes before they impact users.
- Strengthen Recovery Processes: Improve recovery time metrics and reduce operational downtime.
With Steadybit, teams can design precise experiments that minimize risk while uncovering critical insights.
Key Principles of Chaos Engineering
Chaos Engineering focuses on clear principles: start small, measure outcomes, and learn from every experiment. This ensures safe, actionable results.
- Defining the Steady State: A system’s steady state represents its expected performance under normal conditions, measured through key metrics like request latency or error rates.
- Minimized Blast Radius: Limit experiments to specific systems or environments to minimize user impact. Gradually expand the scope as confidence grows.
- Hypothesis-Driven Testing: Use clear predictions to guide experiments. For example, “If a primary database fails, read replicas will maintain query availability.”

Designing Chaos Experiments
Effective chaos experiments are deliberate and well-planned. They simulate real-world conditions to test how systems respond under pressure.
The best chaos experiments:
- Set Objectives: Define what you aim to test (e.g., response to database outages).
- Develop Scenarios: Introduce variables like high CPU usage, dependency failures, or network disruptions.
- Monitor Impact: Observe real-time performance to identify weak points.
- Analyze Results: Translate findings into actionable improvements.
Types of Chaos Experiments
Chaos experiments can target everything from dependency failures to resource constraints. Each type helps teams understand and improve system resilience.
- Dependency Failures: Test how your system handles outages or instability in external services.
- Resource Constraints: Simulate high CPU, memory, or disk usage to assess performance under pressure.
- Network Disruptions: Introduce latency, packet loss, or bandwidth restrictions to evaluate network resilience.

Conducting Chaos Experiments
Chaos experiments follow a simple, repeatable process: plan, execute, and analyze. With the right tools, teams can safely test their systems at any scale.
To execute experiments effectively, follow a structured approach:
- Plan: Identify critical scenarios to test while limiting the blast radius.
- Execute: Use Steadybit’s tools to simulate failures in a controlled environment.
- Analyze: Measure system performance against defined objectives and implement improvements.
Steadybit supports time-based and recurring experiment scheduling, integrating seamlessly with CI/CD pipelines to ensure consistent testing aligned with deployment workflows.
Common Uses for Chaos Engineering
Teams use Chaos Engineering to prepare for outages, validate disaster recovery plans, and improve reliability. It’s about building systems that can handle the unexpected.
- Building Resiliency: Detect and address system vulnerabilities to ensure uptime.
- Disaster Recovery: Validate failover processes and test RTO/RPO compliance.
- Compliance Validation: Prove system readiness for audits or regulatory requirements.
- Improving Site Reliability: Test infrastructure components like load balancers and API gateways under stress.

Challenges in Chaos Engineering and How Steadybit Overcomes Them
While Chaos Engineering delivers tremendous value, teams often face challenges when adopting it. Steadybit is designed to address these obstacles, making it easier to embrace chaos experiments and integrate them into daily workflows.
Cultural Resistance
Many teams hesitate to embrace Chaos Engineering due to fears of causing unnecessary disruptions or the perception that it adds extra work.
Steadybit tackles this head-on with a user-friendly platform that demystifies the process.
By offering intuitive workflows and safety mechanisms, Steadybit helps teams see Chaos Engineering as a manageable and valuable practice rather than a risky or overwhelming initiative.
Resource Constraints
Organizations often worry about the time and effort required to implement Chaos Engineering.
Steadybit reduces this burden by enabling targeted, focused experiments that deliver high-value insights without consuming excessive resources.
The platform’s integration with existing tools and workflows ensures minimal disruption while still providing actionable data.
Technical Complexity
The technical complexity of creating and managing chaos experiments can be daunting, particularly for teams new to the practice. Steadybit simplifies the entire process, from designing experiments to analyzing results.
Predefined scenarios, customizable templates, and real-time observability tools lower the barrier to entry, enabling teams to focus on learning and improving rather than wrestling with implementation.
Getting started with Chaos Engineering
Starting with Chaos Engineering can seem complex, but Steadybit ensures a smooth and straightforward journey.
Here’s how to begin:
1. Define Critical Metrics
Identify and establish baseline metrics that represent your system’s steady state, such as latency, error rates, or throughput. These metrics will help you measure the impact of experiments and evaluate system health.
2. Start Small
Begin with a narrow scope to limit the potential impact. For example, test a single service or a non-production environment first. Steadybit’s platform helps you control the blast radius to ensure safe experimentation.
3. Experiment and Refine
Use the insights from initial experiments to strengthen your systems. Steadybit’s guided workflows and detailed observability features provide clear, actionable feedback, helping teams iterate and improve with confidence.
4. Scale Up Gradually
Once you’ve gained confidence in smaller experiments, expand the scope to include more critical systems or larger portions of your infrastructure. Steadybit makes it easy to scale chaos experiments safely.
