Introduction

With the acceleration of digital transformation, APIs (Application Programming Interfaces) have become the bridge for enterprises to connect internal and external systems and achieve data exchange. In order to better manage and optimize API resources, ensuring service quality and user experience, API7 Enterprise provides a comprehensive, efficient, and secure API management solution. In the following article, we will detail the application and practices of API7 Enterprise in the full API lifecycle management.

API Design and Development Phase

API Style Specification

During the API design and development phase, to ensure the standardization, readability, and maintainability of APIs, development teams usually choose to follow specific API style standards. Among them, RESTful API, with its concise, easy-to-understand, and widely accepted characteristics, has become the most popular and recognized standard in the industry.

API Documentation Specification

Additionally, writing API documentation based on the OpenAPI specification has gradually become an industry trend. OpenAPI files, as a universal API description format, are easy to share and understand among different teams and tools. This helps strengthen collaboration and communication between development, operations, and testing teams, ensuring a consistent understanding of APIs. To efficiently write documentation that conforms to the OpenAPI specification, developers can utilize various API documentation tools, which simplify the writing process and ensure the accuracy and consistency of the documentation.

API Mocking and Testing

During the early stages of development or when dependent services are temporarily unavailable, Mock tools such as Postman or MockServer can simulate API responses, allowing developers to continue working without waiting for the backend. They can also simulate different scenarios to ensure the stable operation of APIs in various situations. Meanwhile, automated testing tools like Jest or Karate are responsible for verifying API functionality, performance, and security. They send requests, check responses, test error handling, and evaluate the performance of APIs under different loads. These tools help developers identify and fix issues early on.

API Deployment and Version Control

With the popularity of microservices architecture, services are broken down into many small, independent parts, reducing the coupling of systems but also posing challenges for unified management of services. API gateways can integrate these scattered services, provide a unified entry point, and offer common functions such as authentication, rate limiting, logging, and monitoring. Implementing these functions separately in each service not only increases development complexity but also hinders system maintenance and scalability. Therefore, an API gateway is almost indispensable in enterprise technical architecture.

Importing OpenAPI Files

After the API design and development are completed and tested, APIs need to be deployed to the production environment, and relevant security policies, traffic management rules, and performance optimization settings need to be configured through the API gateway. API7 Enterprise supports directly importing APIs via OpenAPI files, mapping the fields in the OpenAPI file to services and route resources in API7 Enterprise, facilitating users to quickly configure fine-grained gateways for each API.

Services can also be published to the developer portal for external developers to view and debug API documents.

Version Control

In terms of version control, API7 Enterprise provides flexible service version management capabilities through gateway groups, making it easy for developers to manage and maintain gateway configurations in different environments and versions. It also supports canary traffic shifting to ensure smooth transitions during upgrades or modifications to APIs, reducing the impact on users.

API Monitoring, Security, and Protection

API7 Enterprise provides real-time monitoring capabilities, helping developers understand the runtime status, performance indicators, and abnormal situations of APIs in real time. It also supports integration with third-party monitoring tools, allowing developers to obtain more comprehensive monitoring data and analysis reports.

In terms of security, based on Apache APISIX at the underlying level, API7 Enterprise is equipped with various security mechanisms such as authentication, authorization, and rate limiting can be directly implemented using plugins provided by APISIX, effectively preventing API abuse or attacks. Additionally, SSL certificate resources can help operations and maintenance personnel enhance the security of data transmission through HTTPS more conveniently.

API Operations and Optimization

CI/CD

In terms of CI/CD, API7 provides ADC (APISIX Declarative CLI), helping users implement GitOps capabilities in non-Kubernetes environments. With this tool seamlessly integrated into CI/CD pipelines, users can manage the lifecycle of APIs, simplifying the update and release process and reducing the risk of errors caused by manual operations.

High Availability

High availability is crucial for an API gateway, ensuring that API services remain stable and reliable, even in the face of high concurrency or system failures, to provide uninterrupted service support. High availability is also one of the core considerations in the design of API7 Enterprise. Through mechanisms such as control plane and data plane separation, multi-instance load balancing, health check of upstream status, and configuration synchronization and hot updates, API services are ensured to be always available, capable of easily coping with high-concurrency business scenarios.

Security Practices of API Management Platform

API7 Enterprise also demonstrates outstanding security practices. Through features like token management and audit logging, the security of internal API calls within the platform is effectively guaranteed, achieving comprehensive call tracing. Additionally, API7 Enterprise supports integration with external authentication methods and RBAC (role-based access control). Furthermore, to meet the high standards of security required by specific industries, API7 Enterprise also provides support for FIPS (Federal Information Processing Standards), further enhancing its security and providing enterprises with solid and reliable security guarantees.
