With Elastic Load Balancing, you can add and remove EC2 instances as your needs change without disrupting the overall flow of information. If one EC2 instance fails, Elastic Load Balancing automatically reroutes the traffic to the remaining running EC2 instances. If the failed EC2 instance is restored, Elastic Load Balancing restores the traffic to that instance. Elastic Load Balancing offers clients a single point of contact, and it can also serve as the first line of defense against attacks on your network. You can offload the work of encryption and decryption to Elastic Load Balancing, so your servers can focus on their main task.

HAProxy (High Availability Proxy) is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.

A modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with your existing infrastructure components and configures itself automatically and dynamically.

Originally built at Lyft, Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and “universal data plane” designed for large microservice “service mesh” architectures.

Deploy apps through our global load balancer with minimal shenanigans. All Fly-enabled applications get free SSL certificates, accept traffic through our global network of datacenters, and encrypt all traffic from visitors through to application servers.

Load Balancers are a highly available, fully-managed service that work right out of the box and can be deployed as fast as a Droplet. Load Balancers distribute incoming traffic across your infrastructure to increase your application's availability.

You can scale your applications on Google Compute Engine from zero to full-throttle with it, with no pre-warming needed. You can distribute your load-balanced compute resources in single or multiple regions, close to your users and to meet your high availability requirements.

It ensures that applications are always secure and perform the way they should. You get built-in security, traffic management, and performance application services, whether your applications live in a private data center or in the cloud.

It is a GCE L7 load balancer controller that manages external loadbalancers configured through the Kubernetes Ingress API.

It comes as a pre-built docker image that enables you to easily forward to your websites running at home or otherwise, including free SSL, without having to know too much about Nginx or Letsencrypt.

node-http-proxy is an HTTP programmable proxying library that supports websockets. It is suitable for implementing components such as proxies and load balancers.

It is a web traffic load balancer that enables you to manage traffic to your web applications. It provides autoscaling, SSL offloading, and other advanced features that help you optimize the performance and security of your applications.

Seesaw v2 is a Linux Virtual Server (LVS) based load balancing platform. It is capable of providing basic load balancing for servers that are on the same network, through to advanced load balancing functionality such as anycast, Direct Server Return (DSR), support for multiple VLANs and centralised configuration.

Pound was developed to enable distributing the load among several Web-servers and to allow for a convenient SSL wrapper for those Web servers that do not offer it natively.

It is an HTTP and TCP reverse proxy that configures itself with data from Consul. Traditional load balancers and reverse proxies need to be configured with a config file. The configuration contains the hostnames and paths the proxy is forwarding to upstream services. This process can be automated with tools like consul-template that generate config files and trigger a reload.

Hipache is a distributed proxy designed to route high volumes of http and websocket traffic to unusually large numbers of virtual hosts, in a highly dynamic topology where backends are added and removed several times per second. It is particularly well-suited for PaaS (platform-as-a-service) and other environments that are both business-critical and multi-tenant.

Use real-time RUM data from billions of benchmarks to load-balance your traffic between multiple CDNs and cloud services.

katran is a cpp library and bpf program to build high performance layer 4 load balancing forwarding plane. katran leverages XDP infrastructure from the kernel to provide in-kernel facility for fast packet's processing.

GLB Director is a Layer 4 load balancer which scales a single IP address across a large number of physical machines while attempting to minimise connection disruption during any change in servers. GLB Director does not replace services like haproxy and nginx, but rather is a layer in front of these services (or any TCP service) that allows them to scale across multiple physical machines without requiring each machine to have unique IP addresses.

Vulcand is a programmatic extendable proxy for microservices and API management. It is inspired by Hystrix and powers Mailgun microservices infrastructure.

It is an open-source layer 7 load balancer derived from proprietary Baidu FrontEnd. It supports multiple protocols , including HTTP,HTTPS, SPDY, HTTP2, WebSocket, TLS, etc. And it supports multiple load balancing policies.

You can use it to connect HTTP and TCP services between networks securely. Through an encrypted websocket, it can penetrate firewalls, NAT, captive portals, and other restrictive networks lowering the barrier to entry.

A powerful abstraction that's become increasingly popular to deliver microservices and modern applications. Provides policy, configuration, and intelligence to service proxies.
