Amid the realm of logic and structured thought, architects, much like the mythical creatures of old, harbor a shadowy underside. Like the ancient legends where heroes have their flaws and palaces their haunted chambers, architectural designs, no matter how splendid, possess pitfalls and lurking dangers. The illustrious facades of our software edifices can sometimes obscure the eerie passages and cobwebbed corners inherent within. Like everybody, architects have a dark side, a realm where patterns and practices, if not wielded with caution, can spiral into chilling tales of system horrors. In this paper, we shall venture into this enigmatic domain, shedding light on the specters that haunt our architectural decisions and understanding how to exorcise the demons that threaten our digital sanctuaries. This paper explores various anti-patterns in software architecture such as multi-tenancy, backend for frontend, outbox pattern, CQRS, API gateway, and circuit breaker, discussing the potential issues and challenges associated with each of them. It provides insights on how to address these issues and make informed architectural decisions to ensure the stability, maintainability, and scalability of software systems.
