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.

Multi-cloud traffic has been routed intelligently while security and cost model still need improvement

VMWare Avi Load Balancer can be improved in various ways, as it follows a pay-as-you-go model, which still makes it quite pricey and a little expensive for startups or small-scale industries. They have to pay a lot to use it, and they may not find it reliable for their environment, but for enterprise-level or larger organizations, this tool is excellent. The product's stability has some bugs, and there are reports suggesting quick upgrades. New releases may require patches and fixes. The learning curve for new users is quite tough since the architecture controller and service engine differ from traditional ADCs, requiring an understanding of cloud concepts and networking, plus DevOps. It also has limited advanced traffic control compared to F5 due to a lack of flexibility with F5 rules. It can accept all traffic routes and paths, but when using an advanced setting like an F5 rule, it is not highly flexible with traffic scripting.
