HAProxy - The Reliable, High Performance TCP/HTTP Load Balancer

•    C

---

HAProxy is a fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware.

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.

icmptunnel - Transparently tunnel your IP traffic through ICMP echo and reply packets.

•    C

---

Transparently tunnel your IP traffic through ICMP echo and reply packets.'icmptunnel' works by encapsulating your IP traffic in ICMP echo packets and sending them to your own proxy server. The proxy server decapsulates the packet and forwards the IP traffic. The incoming IP packets which are destined for the client are again encapsulated in ICMP reply packets and sent back to the client. The IP traffic is sent in the 'data' field of ICMP packets.

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.

mtail - extract whitebox monitoring data from application logs for collection in a timeseries database

•    Go

---

mtail is a tool for extracting metrics from application logs to be exported into a timeseries database or timeseries calculator for alerting and dashboarding.It aims to fill a niche between applications that do not export their own internal state, and existing monitoring systems, without patching those applications or rewriting the same framework for custom extraction glue code.

bouncy - bounce HTTP requests around for load balancing or as an HTTP host router

•    Javascript

---

bouncy(cb) returns a new net.Server object that you can .listen() on.If you specify opts.key and opts.cert, the connection will be set to secure mode using tls. Do this if you want to make an https router.

Trafik - A Modern Reverse Proxy

•    Go

---

Træfik (pronounced like traffic) is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease. It supports several backends (Docker, Swarm mode, Kubernetes, Marathon, Consul, Etcd, Rancher, Amazon ECS, and a lot more) to manage its configuration automatically and dynamically.

Envoy - C++ front/service proxy

•    C++

---

As on the ground microservice practitioners quickly realize, the majority of operational problems that arise when moving to a distributed architecture are ultimately grounded in two areas: networking and observability. It is simply an orders of magnitude larger problem to network and debug a set of intertwined distributed services versus a single monolithic application.
