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.

cockatiel - A resilience and transient-fault-handling library that allows developers to express policies such as Backoff, Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback

•    TypeScript

---

I recommend reading the Polly wiki for more information for details and mechanics around the patterns we provide. There are two events, onSuccess/onFailure, that are called when a call succeeds or fails. Note that onFailure only is called if a handled error is thrown.

synapse - A transparent service discovery framework for connecting an SOA

•    Ruby

---

Synapse is Airbnb's new system for service discovery. Synapse solves the problem of automated fail-over in the cloud, where failover via network re-configuration is impossible. The end result is the ability to connect internal services together in a scalable, fault-tolerant way.Synapse solves these difficulties in a simple and fault-tolerant way.

Ethr - Ethr is a Network Performance Measurement Tool for TCP, UDP & HTTP.

•    Go

---

Ethr is a cross platform network performance measurement tool written in golang. Goal of this project is to provide native tool for network performance measurements for bandwidth, connections/s, packets/s, latency, loss & jitter, across multiple protocols such as TCP, UDP, HTTP, HTTPS, and across multiple platforms such as Windows, Linux and other Unix systems. Ethr takes insipiration from existing open source network performance tools and builds upon those ideas. It is very similar to iPerf3 for bandwidth measurements for TCP. iPerf3 has many more options for doing bandwidth measurements such as throttled testing, richer feature set, while Ethr has support for multiple threads, ability to scale to 1024 or even higher connections, multiple clients to single server etc. It is similar to latte on Windows or sockperf on Linux for doing latency measurements.

Fortio - Load testing library, command line tool, advanced echo server and web UI in Go

•    Go

---

Fortio (Φορτίο) started as, and is, Istio's load testing tool and now graduated to be its own project. Fortio runs at a specified query per second (qps) and records an histogram of execution time and calculates percentiles (e.g. p99 ie the response time such as 99% of the requests take less than that number (in seconds, SI unit)). It can run for a set duration, for a fixed number of calls, or until interrupted (at a constant target QPS, or max speed/load per connection/thread).

Nginx - HTTP and reverse proxy server

•    C

---

Nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. It supports accelerated reverse proxying with caching, simple load balancing and fault tolerance, SSL and TLS SNI support, Name-based and IP-based virtual servers and lot more.

SSLsplit - Transparent SSL/TLS interception

•    C

---

SSLsplit is a tool for man-in-the-middle attacks against SSL/TLS encrypted network connections. It is intended to be useful for network forensics, application security analysis and penetration testing. SSLsplit is designed to transparently terminate connections that are redirected to it using a network address translation engine. SSLsplit then terminates SSL/TLS and initiates a new SSL/TLS connection to the original destination address, while logging all data transmitted.

Kong - The Microservice API Gateway

•    Lua

---

Kong is a cloud-native, fast, scalable, and distributed Microservice Abstraction Layer (also known as an API Gateway, API Middleware or in some cases Service Mesh). Backed by the battle-tested NGINX with a focus on high performance, Kong was made available as an open-source platform in 2015. Under active development, Kong is used in production at thousands of organizations from startups, Global 5000 and Government organizations.

multitor - A tool that lets you create multiple TOR instances with a load-balancing traffic between them by HAProxy

•    Shell

---

A tool that lets you create multiple TOR instances with a load-balancing traffic between them by HAProxy. It's provides one single endpoint for clients. Support socks protocol and http-proxy servers: polipo, privoxy and hpts. In addition, you can view previously running TOR processes and create a new identity for all or selected processes. Multitor was created with the aim of initialize many TOR processes as quickly as possible. I could use many instances for my daily use programs (web browsers, messangers and other). In addition, I was looking for a tool that would increase anonymity when conducting penetration tests and testing the security of infrastructure.
