Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management

Struggled with rising costs and limited value while managing internal traffic
The issue with load balancers is that they are all the same. I would rate it seven. I do not recall VMWare Avi Load Balancer having WAF protection. We use WAF and for this specific case, we use F5. It is not about VMWare Avi Load Balancer itself. For multi-cloud capability, you need to do NSX Extended and HCX in VMware. This is what will give you the flavor of multi-cloud. Others will be resources because once you reach NSX Extended, all resources will be under one cloud management. So it does not matter. It is not a feature in VMWare Avi Load Balancer that would be responsible for multi-cloud capability. Multi-cloud capability comes from a configuration called NSX Extended. It is very expensive. The pricing is expensive in that it is only an add-on. From my opinion, they should lower the price.
