Alibaba Cloud API gateway

API Gateway provides high-performance and high-availability API hosting services, helps users to open applications deployed on Alibaba Cloud products such as ECS and container services, and provides complete API publishing, management and maintenance lifecycle management. Users can open data or services quickly, at low cost and with low risk through simple operations. Assist users to realize micro-service aggregation, front-end separation and system integration simply, quickly, with low cost and low risk, and open functions and data to partners and developers.

Provide anti-attack, anti-replay, request encryption, identity authentication, rights management, traffic control and other means. Ensure the security of API and reduce the risk of API opening.

Provide the whole life cycle management of API definition, testing, release and offline, generate SDK and API description documents, and improve the efficiency of API management and iteration.

Provide convenient monitoring, alarm, analysis, API quotes and other operation and maintenance tools to reduce API operation and maintenance costs.

API Gateway maximizes the reuse rate of capabilities, allowing enterprises to leverage each other, and enterprise development can focus on their own business and achieve a win-win situation.

Convenient API management (convenient API management function, convenient API management tool)

API life cycle management: covers the whole life cycle management of API definition, testing and release, facilitates daily management and version management, and supports hot upgrade and quick rollback.

A convenient tool &; Documentation: provide page debugging tools, automatically generate API documents and SDK, greatly reducing labor costs.

Safety and stability (strict authority management, accurate flow control, comprehensive monitoring and alarm)

Security protection: API requests reach the gateway through strict authentication and authority authentication before reaching the back-end service. Support HMAC(SHA- 1, SHA-256) algorithm signature and SSL encryption.

Flow control: you can control the number of API calls allowed per unit time. It is used to protect enterprise back-end services and realize business classification and user classification.

Support API flow control, and different flow controls can be configured according to the importance of API, thus ensuring the stable operation of important services.

Support user, application and exception flow control. Different flow controls can be configured according to the importance of users, thus ensuring the rights and interests of large users.

Flow control granularity: minutes, hours and days.

Request management (filtering invalid requests through parameter verification, realizing high reuse of API through parameter conversion, a set of API services)

Parameter verification: the request passes through the API gateway, and the parameter types and values (range, enumeration, regularization, Json Schema) can be verified according to your configuration, reducing the back-end resource consumption and the processing cost of illegal and invalid requests.

Parameter transformation: parameter mapping rules can be defined in API gateway, and the gateway will translate the back-end service into any form through the mapping rules to meet the different needs of different users and avoid repeated development of functions.

Monitoring and alarm (combined with Alibaba Cloud monitoring service, it provides flexible and comprehensive monitoring and alarm capability, and this part is constantly upgraded).

Monitoring alarm: provide real-time and visual API monitoring, including call volume, call mode, response time, error rate, etc., so that you can clearly understand the running state of API and the behavior habits of users.

Support custom alarm rules, alarm abnormal situations, and reduce fault handling time.

API market (one-stop solution for API management and API implementation)

API market: After accessing the API gateway, the API can be put into the API market in Alibaba Cloud in the form of API service. API gateway and API market will solve the needs of metering and billing, quota control, operation and sales for you.
