Daniel Corbett of HAProxy discusses how load balancers such as HAProxy are used to improve application scalability, reliability, and security. Host Jeremy Jung spoke with Corbett to explain the concept of load and how a load balancer can distribute it across application servers; the open systems interconnection (OSI) model and how it relates to load balancers; how HAProxy compares to other solutions and some of its defining features. Finally, they reflect on how the role of load balancers has changed in the modern landscape of microservices and container orchestration.
