It supports a wide range of platforms including Kubernetes, cloud platforms, and bare-metal, and provides dozens of attacks including packet loss, process killing, and resource consumption. Platforms: Docker, Kubernetes, bare-metal, cloud platformsĬhaosBlade is built on nearly ten years of failure testing at Alibaba. Other mechanisms require you to write your own code. Limited control over blast radius and execution.Creates a mindset of preparing for disasters at any time.Well-known tool with an extensive development history.While Chaos Monkey is historically important, its limited number of attacks, lengthy deployment process, Spinnaker requirement, and random approach to failure injection makes it less practical than other tools. Fortunately, you can configure Chaos Monkey to check for outages before it runs, but this involves writing custom Go code. This is meant to help replicate unpredictable production incidents, but it can easily cause more harm than good if you’re not prepared to respond. You set a general time frame for it to run, and at some point during that time it will terminate a random instance. It only has one attack type: terminating virtual machine instances. From it, Netflix built out an entire suite of failure injection tools called the Simian Army, although many of these tools have since been retired or rolled into other tools like Swabbie.Ĭhaos Monkey is deliberately unpredictable. It was one of the first open source Chaos Engineering tools and arguably kickstarted the adoption of Chaos Engineering outside of large companies. No Chaos Engineering tool list is complete without Chaos Monkey. We’ll provide a table at the end so you can see how these tools compare. We understand how to apply Chaos Engineering to large-scale systems, and which features engineers are most likely to want in a Chaos Engineering solution. Our team at Gremlin has decades of combined experience implementing Chaos Engineering at companies like Netflix and Amazon. This isn’t meant to be a direct comparison between other tools and Gremlin, but rather an objective look at each tool’s features, ease of use, system/platform support, and extensibility. Virtualization software using a type 2 hypervisor is easier to install and manage for smaller projects but can become more difficult to manage as projects grow.In this article, we take an in-depth look at some of the most popular open source and commercial Chaos Engineering tools available in the community. Type 2 hypervisors are installed on top of a server’s operating system. Server virtualization software that uses a type 1 hypervisor is ideal for larger operations that use many server instances. As a result, type 1 hypervisors provide high efficiency and stability. Type 1 hypervisors are installed directly onto the server. Hypervisors are an important part of virtualization software as they allow a host machine to manage multiple virtual machines. Types of Virtualization SoftwareVirtualization software can be distinguished by the type of hypervisor they utilize.
