Focused on reworking interface and ecosystem while load balancing has improved uptime

A10 Networks Thunder ADC is quite solid, but there are some issues that I face, particularly with the user interface. A current issue is that the GUI is less polished than competitors. When compared against F5 BIG-IP or Citrix ADC, the GUI is not as good. The documentation and learning curve are areas that can be improved by A10 Networks. Compared with larger vendors including F5, Cisco, or Palo Alto, A10 has a smaller ecosystem. Although A10 Networks Thunder ADC supports cloud and Kubernetes, many enterprises now expect deeper cloud-native functionality. Improvement areas include Kubernetes Ingress maturity, service mesh integration, and auto-scaling intelligence.

Multi-cloud traffic has been routed intelligently while security and cost model still need improvement

Senior Associate Infrastructure at Publicis Sapient

VMWare Avi Load Balancer can be improved in various ways, as it follows a pay-as-you-go model, which still makes it quite pricey and a little expensive for startups or small-scale industries. They have to pay a lot to use it, and they may not find it reliable for their environment, but for enterprise-level or larger organizations, this tool is excellent. The product's stability has some bugs, and there are reports suggesting quick upgrades. New releases may require patches and fixes. The learning curve for new users is quite tough since the architecture controller and service engine differ from traditional ADCs, requiring an understanding of cloud concepts and networking, plus DevOps. It also has limited advanced traffic control compared to F5 due to a lack of flexibility with F5 rules. It can accept all traffic routes and paths, but when using an advanced setting like an F5 rule, it is not highly flexible with traffic scripting.
