Round robin load balancer

This application allows you to fan out your http requests to different backends via round robin - the easiest strategy of load balancing.

Usage:

• Pass IPs (or domain names) to backends.txt (one address per line)
• Build app via Docker (Dockerfile included) or build binary by running go build and passing -f argument with path to file with list of backends (by default it is backends.txt in a current directory). You can also choose the schema (http/https) via -s argument.

Notice: you can build demo version of program by running ./build.sh. It requires Docker to be installed.

Features:

• Round robin load balancing
• No limitations for the amount of backends to be used
• Health-checks for the backends every 3 minutes

TODO:

• Add an ability to make several attempts to access the backend if no good response received
• Add unit tests
• Add some other strategies of balancing
