Malabarista (portuguese for “juggler”) is a java TCP load balancer built on top of Netty.
It’s an extremely simple project that creates between two endpoints, based on Netty’s TCP tunnel example. Different destination selection algorithms can be used and new ones easily plugged in.
git clone https://github.com/biasedbit/malabarista.git cd src/ant ant jar.loadbalancer
This will create Malabarista.jar in “target” folder.
Example 1: java -jar Malabarista.jar -b*:80 -t10.0.0.1:80 -t10.0.0.2:80 -t10.0.0.3:80 -sRR Run the load balancer on all available NIC's on port 80 and redirect to hosts 10.0.0.1 through 3 using RoundRobin (RR) load balancing strategy. RoundRobin assingns every new incoming connection to the next target host. Example 2: java -jar Malabarista.jar -b10.0.0.100:80 -t10.0.0.1:80 -t10.0.0.2:80 -sFAIR Run the load balancer on 10.0.0.100 port 80 and redirect to hosts 10.0.0.1/2 using FAIR strategy. Fair strategy attempts to balance the number of connections between all target hosts.
Above method will help with load balancing TCP servers using Malabarista.
