Chaos Engineering
0 likes516 views
This document discusses chaos engineering, which involves deliberately inducing failures or errors in a system to test its resilience. It defines chaos engineering and provides an overview of its history and principles. Netflix is cited as pioneering chaos engineering in 2008 with tools like Chaos Monkey that randomly terminate instances. The document outlines the phases of chaos engineering experiments and provides an example using Chaos Monkey for Spring Boot applications. It also notes that while testing is important, chaos engineering generates new information about how systems respond under turbulent conditions.

the equation [unit, regression and chaos
side] are required to get you the level of

Chaos Engineering
- 1. Plain to fail. Embrace the Chaos.
- 2. Nice to meet you Software Engineer @Colpatria Scotiabank Making things happen! Loves reading, programming and teaching. @yurynino @yurynino @yurynino yury.nino.roa
- 3. Agenda ● Why do we have fear of failure? ● What is chaos engineering? ● Principles of Chaos ● Phases of Chaos Engineering ● Chaos in Practice ● Who is using it? ● Review
- 4. Why do we have fear to failure?
- 5. The reality is inherently uncertain, and this uncertainty exposes our limitations.
- 6. This means that failure should be a perpetual consideration even in the best planned and controlled.
- 7. Benefits of failure 1. Is an opportunity to learn. 2. Encourages the creativity. 3. Keeps hungry and humble. 4. Helps to overcome the fear. 5. Becomes Resilient! Try 1 Try 2 Finally
- 8. We need highly available and durable systems. We need Resilient Systems
- 11. Chaos Engineering: Definition! It is the discipline of experimenting on a distributed system in order to build confidence in the system’s capability to withstand turbulent conditions in production. Taken from https://principlesofchaos.org/

- 22. Because …. Writing many unit and integration tests are not enough. ● How does the application behave with network latency? ● What if one of our services breaks down?
- 23. Remember the world is chaotic! ● Unpredictable events are bound to happen. ● Distributed systems contains moving parts. ● Many things can go wrong. ○ Hard disks can fail. ○ The network can go down. ○ Surge in customer traffic can overload.
- 24. February 28th, 2017 will be remembered ● Simple Storage Service (S3) went down in US-EAST ● Outage lasted about 4 hrs. ● 100,000’s of websites across the US impacted.
- 25. Why is it different of Testing?
- 26. Testing vs Chaos Engineering Tests are assertions, whose outputs typically are binary .. while Chaos Engineering is a practice for generating new information.
- 27. I want to emphasize that both sizes of the equation [unit, regression and chaos side] are required to get you the level of availability you want.
- 28. Chaos Engineer is about ... ● Simulating the failure of a datacenter. ● Injecting latency between services. ● Randomly causing exceptions. ● Changing time travel. ● Emulating I/O errors. http://principlesofchaos.org/
