Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.

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.
