What is HAProxy?

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.

What is Pound?

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.

What is Vulcand?

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

          nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. According to Netcraft nginx served or proxied 30.46% of the top million busiest sites in Jan 2018.
          Træfɪk is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease. It supports several backends (Docker, Swarm, Mesos/Marathon, Kubernetes, Consul, Etcd, Zookeeper, BoltDB, Rest API, file...) to manage its configuration 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.
          Squid reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. It runs on most available operating systems, including Windows and is licensed under the GNU GPL.
          Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture.

              We use HAProxy to load balance between our webservers. It balances TCP between the machines round robin and leaves everything else to Node.js, leaving the connections open with a reasonably long time to live to support WebSockets and re-use of a TCP connection for AJAX polling.

              HAProxy manages internal and origin load balancing using KeepaliveD. Two small servers host the entire site, never moving about 15% load even during the largest load spikes.

              We use HAProxy to balance traffic at various points in our stack, includgin nginx nodes on different physical machines, and api nodes on the backend.

              I use HAproxy primarily for application routing and SSL termination. I also use its logs and statistics to visualize incoming traffic in Kibana.

              We use HAProxy to load balance web requests for our web application, but also for some internal load balancing of microservices.
