Handles high traffic efficiently and simplifies complex routing with rule-based logic
I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.
