You still have fleet wide management which can cause issues. Plus there are always a few core services like queues, authz, presentation layer. Also, mono-tenant architectures is no golden bullet either. Such architecture (often coming from a formerly on-premise product that was SaaS-ified) can easily become hell to operate as it multiplies the integration points (DB parameters, URLs, allowlists, etc). It's also quite wasteful in terms of resource utilization and hosting costs.
