Methods used to deploy load balancers and firewalls

Load balancers and firewalls can be attached to the core switches directly or indirectly. Indirect attachment is recommended.
(1) If load balancers and firewalls are attached directly to the core switches, all traffic will pass through them even if unnecessary. This wastes interface bandwidth, increases the risk of network faults, and makes subsequent expansion inconvenient. The advantage is that network speed will be high.
(2) If load balancers and firewalls are attached indirectly to the core switches, only part of the traffic will be transmitted to the corresponding load balancers and firewalls after you configure routing policies or dynamic routing instances on the core switches. This reduces the traffic and the risk of network faults, and makes subsequent expansion and optimization more convenient. The disadvantage is that the network will be slower.
