Possible Minimum Scalable HA Setup¶
Scalable HA (High availability) setup is out of scope in this chapter.
For a HA setup, a load balancer has to be placed in front of the web servers.
To provide high availability with minimum administration overhead for storage
MongoDB driver and for transport use
To have a small footprint while providing HA, you can use two web servers which
