A stable solution that can be used for upgrades, vulnerability remediation, configuration, and standardization
I am using the latest version of Cisco OpenDNS. Users should prioritize the challenges that they have before implementing the solution. They need to be very clear about what they are looking for. Those parameters need to be defined, success criteria need to be checked, and then they can proceed with the solution that meets the requirements. Overall, I rate Cisco OpenDNS a nine out of ten.

Global load balancing has ensured continuous availability and optimized user response times
While F5 BIG-IP DNS is a very powerful solution, some improvements could enhance the overall experience. For example, the user interface could be more modern and simplified. The reporting and analytics features can be improved. Simplified deployment for cloud-native environments could be improved. Overall, F5 BIG-IP DNS is a robust and reliable solution for global traffic management and application availability. With its advanced traffic steering capability, we are definitely getting great benefits from that. However, the user interface is the major thing I think can be improved. The cost also can be reduced. Those are the two or three points that need to be improved. There is some scope for improvement, including the user interface and pricing. That is why I gave it a nine.
