In this course, we will learn about Load balancer concepts and its advantages specifically HAProxy.

HAProxy is flexible, fast and reliable open source software which can provide us with reverse proxy and load balancing ability.

We will conceptually talk about different aspects of HAProxy and load balancing.For each topic we will bring up lab environments by Vagrant and practice what we have learned and we verify the results to meet our expectations.Our basic topic includes:

• HAProxy installation

• HAProxy basic configuration sections

• HTTP mode

• TCP mode

• Non Default ports

We then move to more advanced topics including:

• ACL

• Logging

• SSLtermination

• HA

• Health check and server failure detection

I also added a section on how to automate HAProxy installation and configuration with Ansible at the end of the course(This section is completely optional).

The only prerequisite for this course is basic familiarity of Linux commands, and layers of TCP/IP stack specially TCP protocol and above.

You need a laptop with some tools installed including text editor of your choice,Vagrant,Virtual box.We may also install additional tool during some lectures.

This course is suitable for all system administrator who are willing to learn about load balancer and its applications.Even if you job requires you to work in cloud environment like AWS or Azure, you will gain solid understanding of LB and you could easily adjust your knowledge and apply it in those environments.
