System-level load testing is crucial for reliability and efficiency. It identifies bottlenecks, evaluates capacity for peak traffic, establishes performance baselines, and detects errors. At a company of Airbnb’s size and complexity, we’ve learned that load testing needs to be robust, flexible, and decentralized. This requires the right set of tools to enable engineering teams to do self-service load tests that integrate seamlessly with CI.
系统级负载测试对可靠性和效率至关重要。它识别瓶颈，评估峰值流量的容量，建立性能基线，并检测错误。在像 Airbnb 这样规模和复杂性的公司中，我们了解到负载测试需要强大、灵活和去中心化。这需要一套合适的工具，使工程团队能够进行自助负载测试，并与 CI 无缝集成。
Impulse is one of our internal load-testing-as-a-service frameworks. It provides tools that can generate synthetic loads, mock dependencies, and collect traffic data from production environments. In this blog post, we’ll share how Impulse is architected to minimize manual effort, seamlessly integrate with our observability stack, and empower teams to proactively address potential issues.
Impulse 是我们内部的负载测试即服务框架之一。它提供了可以生成合成负载、模拟依赖关系并从生产环境中收集流量数据的工具。在这篇博客文章中，我们将分享 Impulse 的架构如何最小化手动工作，如何与我们的可观察性栈无缝集成，以及如何赋能团队主动解决潜在问题。
