		+	Global load balancing can use DNS-based approach to resolve domain name to the IP address of the nearest node among the geographically distributed nodes. See [[DNS Load Balancing\|DNS load balancing]] for how to use bind 9 to do global load balancing.
		+
		+	Local load balancing can be used to build network service clusters at one physical location, such as web cluster and cache cluster. [[IPVS]] is an advanced load balancing solution in open source for this purpose.

		+
		+	It includes multiple layers of components:
		+	* Global load balancing is used to distribute traffic to the nearest and/or fastest response node at edge layer
		+	* Edge layer can have geographically distributed cache clusters to speed up content delivery
		+	* Application layer can web clusters to process different web logics
		+	* Memory cache layer can be used to speed up access of persistent data from database
		+	* Storage layer can have database cluster and file storage cluster to store different types of persistent data.
