# Solutions

Every feature in Ecotone exists to solve a real problem that PHP developers face as their applications grow. Find the situation that matches yours:

| If you recognize this...                                                                                                                        | See                                                                              |

| Business logic is scattered across controllers, services, and listeners — nobody can explain end-to-end what happens when an order is placed    | [Scattered Application Logic](/solutions/scattered-application-logic.md)         |
| Queue jobs fail silently, a retry re-fires handlers that already succeeded, or a duplicate webhook double-charges the customer                  | [Unreliable Async Processing](/solutions/unreliable-async-processing.md)         |
| A multi-step process lives across event listeners, cron jobs, and `is_processed` columns — adding or reordering a step means editing many files | [Complex Business Processes](/solutions/complex-business-processes.md)           |
| Support asks "what exactly happened to this order?" and the trail is in logs, timestamps, and hope                                              | [Audit Trail & State Rebuild](/solutions/audit-trail-and-state-rebuild.md)       |
| Services talk over HTTP with custom retry logic per pair, and one service going down cascades into the others                                   | [Microservice Communication](/solutions/microservice-communication.md)           |
| You're evaluating whether PHP can carry enterprise architecture, with the alternative being a rewrite in Java or .NET                           | [PHP for Enterprise Architecture](/solutions/php-for-enterprise-architecture.md) |
