API Gateway State Management via Connection Pooling

The patent introduces an intermediary layer (the computing environment management system) that maintains state information separately from the ephemeral computing resources. This intermediary maintains a state repository that persists application state across resource lifecycle changes, allowing state to be preserved while resources are dynamically allocated and released.

The patent separates state management from the computational dimension by introducing a persistent storage dimension. Application state is migrated from volatile memory tied to specific computing instances to a persistent storage layer that exists independently of resource provisioning cycles, enabling state preservation across dimensional boundaries.

The patent establishes database connections in advance during environment initialization rather than at each invocation. Connection pooling is pre-configured and maintained throughout the environment's lifecycle, allowing multiple function invocations to reuse existing connections without repeated authentication and connection establishment overhead.

The patent creates a universal connection pool that serves multiple function invocations across different customers and applications. A single connection pool infrastructure provides shared access to database resources for multiple workloads, eliminating the need for separate connection management for each function while maintaining security through credential translation and isolation mechanisms.

The patent extracts connection pool management from the application code and places it in the infrastructure layer. Connection pools are owned and managed by the computing environment rather than individual applications, separating the connection management responsibility from the application deployment unit. This allows applications to be stateless and fully portable while connections persist at the infrastructure level.

The patent merges connection management across multiple applications and customers into a shared connection pool infrastructure. Instead of each application maintaining its own separate connection pool, connections are consolidated into a unified pool that serves multiple workloads, improving resource utilization while maintaining isolation through credential translation and access control mechanisms.
