API Management Strategy for NetApp Storage Platform¶

Overview¶

This document outlines the comprehensive API Management strategy for exposing NetApp storage services as products through a secure, scalable, and monitored API gateway using Gravitee.io. The strategy implements a multi-layered security approach with proper governance, monitoring, and lifecycle management.
