#Gateway

An API gateway is the grandiose traffic cop stationed between clients and microservices, equipped with an outrageous array of configuration options and cryptic error codes that mystify developers. It loudly declares its mastery over routing, authentication, and transformation, yet banishes any request with a single misconfigured header to the cold void of 400 Bad Request. It shackles users with chains of caching and rate limits, casting them into the abyss of 404 when they dare stray from the ordained path. In times of smooth operation, it fades into obscurity; at the first sign of trouble it is condemned with cries of design failure, the unappreciated middle manager of distributed systems. Forever doomed to surveil logs and configs, it endlessly parses the arcane dialect of its own creation.
