Featured Reviews

Information Security Engineer at BOK
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
Sasikiran Sakalabattina - PeerSpot reviewer
Infrastrecture Engineer at TechMahindra
Centralized load management has improved availability and reduces manual effort for critical apps
The features we use most frequently in VMware Avi Load Balancer are virtual services, backend pools, health monitoring, and Layer 7 load balancing. Virtual services are a component of VMware Avi Load Balancer that serves as the primary entry point for the client traffic. In our application, I regularly create and manage the virtual services for the web applications, APIs, and internal business applications. We configure SSL certificates for load balancing the policies and health monitoring at the virtual service. The best feature of VMware Avi Load Balancer is health monitoring. The most valuable feature for me is the health monitoring capability. In our production environment with more than one thousand virtual machines, it continuously checks the health of the backend application servers. During monthly Windows patching or unexpected application failures, unhealthy pool members are automatically removed from the service. This feature is significantly reducing the traffic directed to unhealthy services without any manual intervention. Once the application server is restored, VMware Avi Load Balancer automatically adds the server back to the pool. This feature has significantly improved the application availability and is reducing the business downtime. Due to this, manual interventions required are minimal, so it is saving time.
