NGINX: upstream load balancing
When to use
Use this skill for upstream load balancing in NGINX. This skill specifically handles upstream load balancing and nothing else in the NGINX family.
Procedure
Define an upstream block across several backends, pick a balancing method (round-robin, least_conn, ip_hash), and set health checks.
Notes
This is the NGINX skill dedicated to upstream load balancing. Sibling skills cover other NGINX capabilities; this one is the right choice only when the task is about upstream load balancing.
