The API gateway is a server located between the application and the front -end service, mainly a program interface that manages, monitor and protects the application. It can be regarded as the access port of API requests, responsible for management to determine the request, and then forward it to appropriate endpoint services, and perform multiple operations when necessary, such as verification of identity, authorization, traffic management, data conversion, etc. The API gateway can help enterprises or organizations have better API management, security, performance, scalability, and can also provide better monitoring and analysis.

　　What are the main functions of the API gateway?

　　API management

　　The API gateway allows you to centrally manage all API interfaces, including adding, modifying, deleting and version control APIs. This simplifies the management and maintenance process of API.

　　flow control

　　The API gateway can control and restrict the formulated API request to prevent malicious attacks or over -use resources.

　　Access control and security

　　The API gateway can implement identity verification and authorization to ensure that only users who have undergone authentication can access specific API resources. Safety measures such as data encryption and preventing cross -site request format (CSRF) can also be performed.

　　Request forwarding and load balancing

　　The API gateway can forward requests to appropriate load services according to the request content, goals and load balancing strategies, thereby dispersing traffic and improving performance.

　　cache

　　The API gateway can cache response to reduce the request for cloud services, thereby improving the speed and efficiency of response.

　　Monitoring and analysis

　　The API gateway can record the API request and response information, providing real -time monitoring, log records and analysis to help you understand the usage and performance of the API.

　　Log and audit

　　The API gateway can generate detailed access logs and audit reports in order to perform fault exclusion and compliance checks when required.

　　Data conversion and protocol conversion

　　The API gateway can transform the data format and convert the established request from one format to another, which allows different types of clients to interact with API.

　　The API gateway provides a centralized management and protecting API solution to help enterprises/organizations better management and controller APIs to improve security, performance, and scalability.
