Managing the API gateway sprawl

Managing API gateway sprawl involves addressing the complexities and challenges that arise when an organization uses multiple API gateway vendors, which is common in medium-to-large enterprises due to factors such as local procurement, mergers and acquisitions, cloud migration, multi-cloud vendor support, and regulatory requirements. To tackle this, organizations should aim to unify API governance by establishing consistent standards and practices across different groups and gateways, potentially consolidating to fewer vendors or maintaining a federated approach. Additional strategies include unifying authorization through a central management layer, creating a central API catalog to enhance visibility, implementing distributed logging for traffic analysis, using reverse proxies for non-gateway APIs, and adding correlation identifiers for troubleshooting across gateways. These efforts aim to make interoperability across multiple API gateway vendors feasible while ensuring consistency and security within the API ecosystem.
