What are API Gateway services in OCI used for?

API Gateway services in Oracle Cloud Infrastructure (OCI) are primarily utilized to create, publish, and manage APIs securely. This service plays a crucial role in modern cloud applications where APIs act as the interface enabling communication between different software applications.

With API Gateway, organizations benefit from a centralized management point where they can define API endpoints, manage traffic, enforce security policies, and ensure that the APIs are accessible only to authorized users or applications. This capability is essential for ensuring robust security and reliable performance, as it allows for monitoring, versioning, and analytics on API usage.

The other options focus on different functionalities that are not the primary purpose of the API Gateway. Hosting static websites pertains to web hosting services, managing database connections involves database management solutions, and deploying machine learning models relates to machine learning services rather than API management. Therefore, these options do not align with the core capabilities of the API Gateway service in OCI.
