[chris-cmsoft]

We have used Litmus to build out Chaos Engineering platforms with some of our large E-Commerce customers to improve resilience for big sales periods such as Black Friday.

We looked into quite a few tools, and Litmus provided us with the flexibility we needed, whilst bootstrapping many of the components we would have to write ourselves.

We also used Litmus Chaos experiments when discussing some of our customer's architecture constraints, and showing them real world cases of how to make Kubernetes more resilient.

• One concrete use case was our customer wanting to build a cluster per app, whilst we wanted to build bigger clusters for easier management. We would use Litmus to show what application failure looks like on one part of the cluster, and show global resilience in their cluster when this happens.

The Litmus community and *product have been a great addition to our tool stack, and provided many benefits for us.

[bbarin]

We have been using Litmus 2.X at iFood for a couple of months, replacing chaostoolkit as it provides a wider range of experiments out-of-the-box. We've started using it to validate the fallback mechanisms of critical services monthly. Right now, we are expanding its usage to go further and inject failures to drop access to databases, redis, Kafka and AWS services and learn from it and take some countermeasures to improve the critical services.
I hope Litmus to become the de-facto tool to implement Chaos Engineering in a simple manner.

We at FIS Global, have been embarking on to larger SRE program to transform platform teams from purely operations focused to bring in SRE/Automation culture and mindset. As part of that larger effort, Chaos/Resiliency Engineering is identified as key program to improve stability and availability thus improve overall reliability of applications across organization and provide superior customer experience. We have chosen Litmus as a Chaos Engineering Tool because, It

• Fulfills all of resiliency testing requirements
• Has good and responsive community
• Has good documentation
• is built on loosely coupled architecture
• Has nice dashboard features
• Exposes APIs to integrate with CI/CD pipelines

Where we are using Litmus

• Currently, using in Applications/Workloads but idea is to expand to Infrastructure, e.g. using network latency to identify and understand resiliency of upstream application/component when downstream application/component is slow, Use Pod delete under production load to understand the application's ability to self heal.
• Simulate experiments using Litmus to understand utilization of JVM's key resources such as thread pool, connection pool, heap memory etc
• Kafka Resiliency : Kafka itself is a complex distributed architecture solution, planning to use Litmus network and memory hog experiments to simulate latency between Producer and Broker, Consumer and Broker, Leader and Follower, and also trying to understand how cluster behaves under Memory and CPU pressure.
• Integrate Litmus with CI/CD over APIs so that Chaos Testing can be autonomous

[bjoky]

At Infor we have a resilience team for one of our products. In that team we are using Litmus as the main tool for chaos engineering. Some of our reasons for choosing it were that it is an open-source tool with an active community and that it runs in Kubernetes.

Litmus was our entry point into chaos engineering, and it provided us with a palette of possible experiments and types of failures to choose from. We use it to simulate failures on workloads in Kubernetes environments for development, testing and pre-production, but not yet in production environments.

So far, we have mainly used Litmus for “game day” style workshops. We gather the team working with a component and we run a few experiments together with them. But we have also started using it for running automated experiments in controlled environments and are also looking into integrating it in our CI/CD pipeline.

Our experience with running Litmus and chaos engineering workshops has in general been positive. Besides running the tool, we have also put emphasis on the preparation and follow-up phases of our chaos experiments. We have found that the discussions about resilience and chaos engineering is of value for the developers and helps create a culture of resilience that improves the quality of our product.

Resilience is a key aspect in creating fault-tolerant environments, and leveraging tools like Litmus has been instrumental in automating resilience testing. Litmus has enabled us to simulate real-time chaos scenarios, allowing us to thoroughly verify the robustness of both our infrastructure and applications.

We began with a proof of concept (POC) on a playground cluster. While we explored other tools during this process, Litmus stood out significantly, not only in its capabilities but also due to its excellent user interface. Although we faced a few challenges during the initial setup of Litmus on OpenShift, the team provided timely support, helping us overcome these obstacles and successfully complete the POC.

Now, we've successfully deployed Litmus in a non-production cluster environment, and our SRE team is in the process of transitioning from manual chaos testing to automated chaos tests. This shift will enable us to schedule, automate, and efficiently track the outcomes of these tests, enhancing the resilience of our systems.
