A typical enterprise cloud initiative often begins with a clear goal: improve scalability, accelerate releases, and enable better customer experiences. But progress quickly slows when legacy systems enter the picture. Critical systems such as billing, ERP, and inventory platforms were never designed for real-time connectivity. They operate on tightly coupled architectures, batch processes, and undocumented dependencies. When modern cloud applications attempt to interact with them, integration becomes fragile and unpredictable. This is where API enablement for legacy systems becomes essential. APIs act as a controlled bridge between legacy infrastructure and modern cloud platforms, enabling communication without disrupting core operations. However, exposing legacy systems through APIs is not as simple as adding endpoints. Done incorrectly, it can overload systems, introduce security vulnerabilities, and create long-term instability.…
