loadcat - NGINX load balancer configurator

•    Go

---

Loadcat is an Nginx configurator that allows you to use Nginx as a load balancer. The project is inspired by the various Nginx load balancing tutorial articles available online and also the existence of Linode's load balancer service NodeBalancers. So far the tool covers some of HTTP and HTTPS load balancing features, such as SSL termination, adding servers on the fly, marking them as unavailable or backup as necessary, and setting their weights to distribute load fairly. Loadcat parses a TOML encoded configuration file. In case one is not found, Loadcat will create one with same sane defaults. The location of the configuration file can be specified with the -config flag.

glb-director - GitHub Load Balancer Director and supporting tooling.

•    C

---

The GitHub Load Balancer (GLB) Director is a set of components that provide a scalable set of stateless Layer 4 load balancer servers capable of line rate packet processing in bare metal datacenter environments, and is used in production to serve all traffic from GitHub's datacenters. GLB Director is designed to be used in datacenter environments where multiple servers can announce the same IP address via BGP and have network routers shard traffic amongst those servers using ECMP routing. While ECMP shards connections per-flow using consistent hashing, addition or removal of nodes will generally cause some disruption to traffic as state isn't stored for each flow. A split L4/L7 design is typically used to allow the L4 servers to redistribute these flows back to a consistent server in a flow-aware manner. GLB Director implements the L4 (director) tier of a split L4/L7 load balancer design.

Sidekick - High Performance HTTP Sidecar Load Balancer

•    Go

---

sidekick is a high-performance sidecar load-balancer. By attaching a tiny load balancer as a sidecar to each of the client application processes, you can eliminate the centralized loadbalancer bottleneck and DNS failover management. sidekick automatically avoids sending traffic to the failed servers by checking their health via the readiness API and HTTP error returns.

minuteman - A distributed Load Balancer

•    Erlang

---

A distributed, highly available service discovery & internal load balancer for distributed systems (microservices and containers). You can use the layer 4 load balancer by specifying a VIP from the Marathon UI. The VIP must be specified in the format IP:port, for example: 10.1.2.3:5000. Alternatively, if you're using something other than Marathon, you can create a label on the port protocol buffer while launching a task on Mesos. This label's key must be in the format VIP_$IDX, where $IDX is replaced by a number, starting from 0. Once you create a task, or a set of tasks with a VIP, they will automatically become available to all nodes in the cluster, including the masters.

Neutrino is a software load balancer(SLB) is used by eBay to do L7 Switching and Load Balancing for eBay’s test infrastructure. It is build using Scala and Netty and it uses the Java Virtual Machine (JVM) as run-time environment. Ebay was looking for options to replace their hardware load balancers which are expensive and unable to keep up with the demand. There were two options, either take an open source product like HAProxy or build an in-house one.
