HAProxy Load Balancing
Learn how HAProxy distributes traffic across backend services through HTTP and TCP load balancing, statistics dashboards, and access-control logic. This course introduces the practical load-balancing skills needed to improve availability and control traffic flow in multi-node service environments.
Why It Matters
As services grow, one server is rarely enough. Load balancers help spread requests, expose health information, and apply routing decisions before traffic reaches the application layer. Operators need to understand how a load balancer is configured and validated because it often becomes the front door to production systems.
What You Will Learn
- Install HAProxy and understand its place in a service delivery stack.
- Configure HTTP load balancing across backend servers.
- Use the HAProxy dashboard and statistics view for visibility.
- Work with TCP load balancing for non-HTTP services.
- Apply ACLs and smarter routing logic to direct traffic intentionally.
- Use these skills in a high-traffic web cluster challenge.
Course Roadmap
The course begins with HAProxy installation so you can establish a working load-balancing service. It then moves to HTTP load balancing, where you distribute web requests across backend nodes and observe how frontends and backends are connected.
Next, the course introduces the statistics dashboard so you can inspect health and traffic behavior visually. After that, you learn TCP layer balancing for services that do not speak HTTP, followed by ACL-based routing that allows more selective traffic handling.
The course ends with the High Traffic Web Cluster challenge, where balancing strategy, observability, and routing logic all contribute to a more complete front-end traffic-management scenario.
Who This Course Is For
This course is for Linux learners and DevOps practitioners who need a practical introduction to load balancing in front of multi-node services.
Outcomes
By the end of this course, you will be able to configure HAProxy for HTTP and TCP services, inspect load-balancer health and behavior, and apply routing logic that supports more resilient service delivery.
