Learn how Harness Resilience Testing helps teams build resilient systems by simulating failures and identifying vulnerabilities.
TL;DR
- Chaos engineering simulates real-world failures to identify vulnerabilities before they cause production outages, helping teams build confidence in system resilience.
- Harness Resilience Testing includes 230+ chaos experiments covering Kubernetes pod deletion, CPU and memory stress testing, network latency injection, and VMware VM failures.
- The platform integrates directly with CI/CD pipelines and GitOps workflows, enabling resilience testing as part of automated software delivery.
- Enterprise-grade security features include self-hosted deployment options, air-gapped environments, and private chaos experiment repositories (Private Chaos Hubs).
- Organizations practicing proactive chaos engineering reduce mean time to recovery (MTTR) and prevent downtime that costs an average of $5,600 per minute [Source: Gartner, cited in "The True Cost of IT Downtime," CatchMark Technologies, 2024].
Today, we launched our latest module in the Harness Software Delivery Platform – Harness Resilience Testing (RT) – into public preview. Harness Resilience Testing empowers teams to deliver more resilient systems, helping organizations avoid downtime that can be costly, both financially and in lost reputation.
Harness Resilience Testing enables DevOps and SRE teams to purposely create failure scenarios (“chaos”) to identify potential resiliency and reliability issues in their deployments. These scenarios go beyond traditional unit, integration, and system tests, more closely representing what random failures in a production operating environment would look like. This insight into how your systems behave under defined failure scenarios equips teams to understand weak links that exist in the applications and infrastructure, and proactively create resilience to help prevent costly downtime.
Chaos Engineering – Making Your Systems More Resilient
Some of the systems-level failure scenarios for which Harness Resilience Testing provides chaos experiments include:
- The ability to validate systems remains available as Kubernetes pods are deleted.
- CPU and Memory hogs at the pod, node, application, and infrastructure levels.
- Injection of network challenges, such as increased latency and network corruptions, and DNS failures.
- Virtual machines in VMware environments can be stopped for a defined time period and then restarted.
The Next Evolution of Chaos Engineering
Chaos engineering is a concept that is rapidly gaining popularity in software delivery. Harness RT is far more than just another solution to meet the chaos engineering need. Here are a few ways in which Harness is unique in helping companies deliver reliable systems with chaos engineering:
- Coverage of as many real-world failure experiments as possible leads to more reliable deployments and therefore less downtime. Harness RT includes – by far – the most experiments available through any provider (48 at the time of publishing), but also the ability for users of Harness RT and the open-source project Litmus to contribute experiments back to the project. This means that you will have access to a continually growing library of different chaos experiments to use to protect against the effects of downtime.
- Creating reliable systems is a team sport. Many teams need information from chaos experiments to help create reliability. To ensure that all involved can get the access and information they need, Harness RT provides integration to CI/CD, GitOps, and integration with your existing observability tools. Other chaos solutions in today’s market aren’t as pipeline-aware or pipeline-integrated as Harness Resilience Testing, excluding teams outside of SRE that are necessary to help accelerate the effort to make systems more reliable.
- Information about where vulnerabilities exist in systems is highly sensitive information. Harness enables enterprise-grade security and privacy controls of all experiments run, as well as the results of those experiments through support for our self-hosted, on-premises, and air-gapped deployments of RT. Additionally, Harness RT provides support for fully private chaos experiment repos (called ‘Private Chaos Hubs’) to contain both the included experiments you desire to run and those you have created - even the experiments you’re running to fortify your systems can be entirely private.
