toxiproxy - :alarm_clock: :fire: A TCP proxy to simulate network and system conditions for chaos and resiliency testing

•    Go

---

Toxiproxy is a framework for simulating network conditions. It's made specifically to work in testing, CI and development environments, supporting deterministic tampering with connections, but with support for randomized chaos and customization. Toxiproxy is the tool you need to prove with tests that your application doesn't have single points of failure. We've been successfully using it in all development and test environments at Shopify since October, 2014. See our blog post on resiliency for more information.Toxiproxy usage consists of two parts. A TCP proxy written in Go (what this repository contains) and a client communicating with the proxy over HTTP. You configure your application to make all test connections go through Toxiproxy and can then manipulate their health via HTTP. See Usage below on how to set up your project.

toxy - Hackable HTTP proxy for resiliency testing and simulated network conditions

•    Javascript

---

Hackable HTTP proxy to simulate server failure scenarios, resiliency and unexpected network conditions, built for node.js.It was mainly designed for failure resistance testing, when toxy becomes particularly useful in order to cover fault tolerance and resiliency capabilities of a system, especially in disruption-tolerant networks and service-oriented architectures, where toxy may act as MitM proxy among services in order to inject failure.

Istio - An open platform to connect, manage, and secure microservices

•    Go

---

An open platform to connect, manage, and secure microservices. Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio's control plane provides an abstraction layer over the underlying cluster management platform, such as Kubernetes, Mesos, etc.

sentinel-golang - Sentinel Go version (Reliability & Resilience)

•    Go

---

As distributed systems become increasingly popular, the reliability between services is becoming more important than ever before. Sentinel takes "flow" as breakthrough point, and works on multiple fields including flow control, circuit breaking and system adaptive protection, to guarantee reliability and resiliency of microservices. See the 中文文档 for document in Chinese.

go-resiliency - Resiliency patterns for golang

•    Go

---

Resiliency patterns for golang. Based in part on Hystrix, Semian, and others.Follows semantic versioning using https://gopkg.in/ - import from gopkg.in/eapache/go-resiliency.v1 for guaranteed API stability.

semian - :monkey: Resiliency toolkit for Ruby for failing fast

•    Ruby

---

Semian is a library for controlling access to slow or unresponsive external services to avoid cascading failures.Resource drivers are monkey-patched to be aware of Semian, these are called Semian Adapters. Thus, every time resource access is requested Semian is queried for status on the resource first. If Semian, through the patterns above, deems the resource to be unavailable it will raise an exception. The ultimate outcome of Semian is always an exception that can then be rescued for a graceful fallback. Instead of waiting for the timeout, Semian raises straight away.

pod-reaper - Rule based pod killing kubernetes controller

•    Go

---

A rules based pod killing container. Pod-Reaper was designed to kill pods that meet specific conditions. See the "Implemented Rules" section below for details on specific rules. Additionally, at least one rule must be enabled, or the pod-reaper will error and exit. See the Rules section below for configuring and enabling rules.

cdk-stepfunctions-patterns - A set of Step Functions high-level resiliency patterns.

•    TypeScript

---

cdk-stepfunctions-patterns library is a set of AWS CDK constructs that provide resiliency patterns implementation for AWS Step Functions. All these patterns are composable, meaning that you can combine them together to create quite complex state machines that are much easier to maintain and support than low-level JSON definitions.
