HAProxy Crash Course - TLS 1.3, HTTPS, HTTP/2 and More

Dive into a comprehensive crash course on HAProxy, exploring its architecture, functionality, and advanced features. Learn about HAProxy's role as a high availability layer 4 and layer 7 load balancer and proxy. Discover how to implement TCP and HTTP proxying, utilize Access Control Lists (ACLs), and understand the differences between TLS termination and pass-through. Follow along with practical examples, including spinning up services, installing HAProxy, and configuring it for various scenarios. Master ACL conditionals, URL rejection, and enabling HTTPS and HTTP/2 on HAProxy. Gain hands-on experience with provided source code for applications and HAProxy configurations, and access additional resources for further learning on software architecture, database engineering, network engineering, and more.
