Local and global traffic can be load balanced across servers and datacenters to distribute traffic loads and ensure services remain uninterrupted if servers fail. Load balancing distributes equal amounts of traffic, while load sharing distributes traffic without ensuring balance. Local traffic balancing distributes traffic between servers on a local network, and protects services if servers fail, while global balancing distributes traffic optimally across datacenters worldwide based on location. Well-known load balancing products are commonly used to implement these strategies.

2. Load Balancing VS Load Sharing
Ø Load Balancing: traffic is balanced across
different links, equal or closely equal amounts.
Ø Load Sharing: traffic is only shared across
different links without being necessarily
balanced.

3. Local Traffic Load Balancing
Traffic can be load-balancing between servers in the local
network

4. Local Traffic Load Balancing(cont.)
When one or more servers are down, the others will handle
the traffic, no any service interrupted

5. Global Traffic Load Balancing
Traffic can be load-balancing across the world or different
datacenter

6. Global Traffic Load Balancing(cont.)
Traffic can be shared based on geo topology and can provide
the most optimal servers

7. Global Traffic Load Balancing(cont.)
Services can still be protected while one location server
down
