Featured Reviews

Global load balancing has improved reliability and currently reduces latency across multi-cloud

Head Of Technical And Network Security at Connex Information Technologies

I have experience with AWS, and I also have experience with both AWS and Azure, and sometimes GCP as well. We utilize multi-cloud support with A10 Networks Thunder ADC. We have customers utilizing A10 Networks Thunder ADC in the public cloud as well. I didn't technically involve myself with analytics in A10 Networks Thunder ADC because I haven't been involved in that part in the past few years. According to my team, the analytics tools are quite prominent, so there are no issues there. We have a distributorship with A10 Networks and are considered a partner. I would rate this review 9 out of 10.

Centralized load management has improved availability and reduces manual effort for critical apps

V Mware And Vector Administration at Tech Mahindra Limited

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.
