F5 can completely close all issues in infrastructure about application delivery control because these solutions have all the instruments to close these issues.
Speaking about F5 BIG-IP DNS Global Traffic Manager, at a worldwide level, we get the opportunity to secure DNS records. Also, we have the opportunity to secure if customers have opted into DNS in the local area. You can make all DNS requests through only F5 BIG-IP DNS. Also, you can do any manipulation or modification with this traffic. In just one year, I can't know what F5 could do because there are a lot of things and a lot of instruments to push any task, especially because of the killer feature in F5 firewall. It also has a scripting language in which you can do whatever you want. If you know the TECO language, it's based on the TECO language. You can write, so we use something else to work with traffic, like an SAP application with APM and DNS, with which you can create some custom rules. So, if some feature doesn't have something in advance, you can create that feature. I think it's some of the best features of the solution.
I don't know precisely how it improved the functioning of my organization since, from my experience, I can say that it can close all issues in infrastructure, especially application publishing.
