Featured Reviews

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

Analytics dashboard has provided deep visibility and delivers reliable load balancing and WAF protection
Regarding the benefit of VMWare Avi Load Balancer's WAF protection, I think the heuristics are pretty common. I do not come across many trainings for the WAF part, but once in a while. I cannot comment much on whether organizations are using it or not. In terms of VMWare Avi Load Balancer's multi-cloud capability, I have not come across many organizations using it across the different platforms. It is primarily used in the VMware context only. I have not seen anyone using it purely from a Linux or AWS or Azure perspective. Most of the organizations I come across are primarily using it from the VMware side. As for the API-driven infrastructure as code feature of VMWare Avi Load Balancer, because I am not from the developer side, I think that is more for the developers or maybe for integrating some new solutions and digging something deeper into it. That is quite handy. Regarding ease of use with VMWare Avi Load Balancer, that is pretty okay. For implementation, people find it quite okay to implement. There is nothing much from the implementation side. I think VMWare should promote their product more, particularly from the VMWare Avi Load Balancer side. It may be promoted a little bit more. Apart from Avi, most of those are already well-known. I would rate this review an 8 out of 10.
