How does ensuring high availability work? The F5 BIG-IP Local Traffic Manager product is a proxy server that is placed in front of the server farm on which the application runs. It actively monitors the status and health of the servers, their ongoing load, the amount of user requests and continuously balances the load on the servers according to various algorithms. The F5 BIG-IP Local Traffic Manager also allows you to optimize traffic and relieve the load on servers or teams taking care of server traffic. Not only can it optimize TCP traffic, but it also makes it easy to manage encrypted TLS traffic, compressed HTTP traffic, or optimize HTTP. Are you considering moving to more modern communication protocols such as IPv6 or HTTP/2 or HTTP/3? Again, F5 BIG-IP Local Traffic Manager is a solution that is directly built to take advantage of these modern protocols.
When an application is running in multiple data centers, public or private clouds, you may be faced with the question of how to direct users to the most appropriate or closest data center. The F5 BIG-IP DNS product is an intelligent DNS system that has been developed for exactly these operations. It monitors individual applications in all data centers, keeps track of how many connections each individual application in a given data center is serving, finds out where the user is coming from (yes, even geographically, e.g. which city in the world), and uses smart algorithms to direct the user to the best data center or cloud. This application delivery management technology is known as Global Server Loadbalancing (GSLB). F5 BIG-IP DNS is not just a smart GSBL solution. It is also a full-featured secure DNS server, simplifying DNS infrastructure management and deploying modern security standards such as DNSSEC, DNS over HTTP (DoH) or DNS over TLS (DoT).
