Enterprise mobile applications have emerged as new revenue drivers for companies with legacy applications and data. Exposing these backend services to developer communities' enables creation of value added composite apps used by a new market of mobile consumers. However, most enterprises today concentrate on how to fit mobility and the 'app' economy into existing infrastructure with minimal changes. Enterprises are still learning how to change their server-side and middleware architecture to fit the newer, faster, quicker, more efficient mobile taxonomy.
Service/API Gateway mobile middleware bridges the gap between legacy apps and the sea of heterogeneous mobile platforms, operating systems, and programming languages used today. The traditional 3-tier web architecture is collapsed into a single application proxy that handles all API and service security, including OAuth, secure integration and mediation to external cloud services, high performance data translation, especially for JSON content. It also handles caching of JSON responses, SLA management, and integration with Enterprise directories for policy decision support.
