Load balancing of F5
Load balancing is a technology, which refers to the method of realizing load sharing through some algorithm. Generally speaking, it is to uniformly allocate the requested equipment. Load balancing will receive all requests uniformly, and then distribute these requests to all members of this load balancing group according to the set algorithm, so as to realize the balanced distribution of requests (loads).

F5 BIG-IP LTM (Local Traffic Manager) is a device that manages and distributes traffic and content. It provides a flexible algorithm of 12, and effectively forwards the data stream to the server group to which it is connected. Facing users, it is just a virtual server. At this point, users only need to access the server defined on BIG-IP LTM, that is, the virtual server. But their data streams are flexibly balanced to all physical servers through BIG-IP. BIG-IP LTM can allocate traffic through various load balancing algorithms, including:
