Description

A load balancer is a component that, once invoked, distributes incoming requests to a list of registered providers and returns the value obtained from one of the registered providers to the original caller. This project intents to simulate the behavior of two types of load balancers with providers that create artificial load when invoked.

Types of load balancers

• Randomized Load Balancer
• Round Robin Load Balancer

Dependencies

Compile Maven Dependencies

1. Apache Log4j API 2.17.2 (log4j-api)
2. Apache Log4j Core 2.17.2 (log4j-core)

Test Maven Dependencies

1. JUnit Jupiter API 5.8.2 (junit-jupiter-api)
2. JUnit Jupiter Engine 5.8.2 (junit-jupiter-engine)
3. JUnit Jupiter Params 5.8.2 (junit-jupiter-params)
4. Awaitility 4.2.0 (awaitility)

Usage

Build with Maven

# Install
mvn install

# ...or compile
mvn compile

# ...or package
mvn package

Test with Maven

Unit tests cover all the scenarios for request load balancing for both types of load balancers implemented in the project.

# Test
mvn test

NOTE: Since the unit tests simulate various scenarios for Load Balancing, running all the tests might take a long time (approximately 1 minute on an Apple M1 powered computer with 32 GB of RAM).
