What Is an API? What Is API Management?​

Recently, the application of AI-generated content (AIGC) has become increasingly popular in various industries. AIGC service providers provide their content generation capabilities to the outside world through APIs, enabling users to easily access AIGC-related content. Obviously, APIs have become an important pillar of AIGC applications. So, what exactly is an API?

API (Application Programming Interface) is a set of predefined rules and conventions for communication between different software applications. APIs enable software applications (clients) to request functionality and data from other software applications (servers), facilitating interaction and data sharing between different systems. By leveraging APIs, developers can use the functionality of other applications, allowing them to build and release new applications more quickly.

API management involves the processes of creating and publishing APIs, formulating usage policies, controlling access rights, cultivating user communities, collecting and analyzing usage statistics, and reporting performance, typically including components such as an API gateway and a developer portal. Among these, the API gateway, as a key component, is responsible for handling and forwarding requests, as well as executing security and performance policies, while the developer portal is an online platform that provides developers with API documentation, key management, and other related resources.

As enterprises increasingly rely on APIs to drive digital transformation, the importance of API management has unprecedentedly risen. After a brief introduction to the relevant concepts above, we will explore the top ten trends in API management.

1. API Security is Becoming Increasingly Important​

API security refers to the process of protecting the exchange of data and functionality between applications and systems through APIs. The primary goal of API security is to ensure the correctness, reliability, and confidentiality of data and functionality, and to prevent unauthorized access and potential malicious attacks. API security is critical for modern applications and enterprise services, as they heavily rely on APIs for data exchange and integration. The following are several important reasons why API security is crucial:

1. Data protection: APIs are often used to transmit sensitive data, such as user information, transaction details, and payment information. Ensuring API security can prevent data leaks, tampering, and loss, protecting the information security of users and enterprises.
2. System integrity: Maintaining system integrity by ensuring that APIs can only be accessed by authorized users and compliant applications can help prevent malicious attackers from compromising or controlling the system through APIs.
3. Trust and reputation: A secure API is crucial in establishing user trust in enterprise services and building a positive brand reputation. Conversely, inadequate API security can harm the reputation of the enterprise and result in loss of users.

To ensure API security, API gateways are commonly used to manage security features like identity authentication and access control, which protect APIs from unauthorized access and attacks.

There are numerous API gateways available on the market, one of which is Apache APISIX. Apache APISIX is a cloud-native API gateway under the Apache Software Foundation that boasts dynamic, real-time, and high-performance capabilities. It provides a range of security features to ensure API security, including authentication via plugins like key-auth and jwt-auth, and access control via plugins like consumer-restriction. These features help businesses prevent data leaks and protect user privacy and enterprise interests.

2. The Increasing Importance of API Standardization​

As APIs become increasingly prevalent, standardizing their design is of growing importance. The following are several benefits of API standardization:

1. Facilitates collaboration and communication within an organization by ensuring that different teams and departments adhere to uniform design principles and standards, thereby enhancing development efficiency and quality.
2. Enhances the security and stability of APIs by defining clear interfaces, data structures, and protocols, thereby mitigating the risks of errors or misuse.
3. Improves the extensibility and interoperability of APIs by adhering to industry or community-recognized design guidelines or best practices, enabling APIs to adapt to diverse scenarios and requirements.

In the process of API standardization, a common API standard specification is the OpenAPI Specfication. Many tools and platforms support this specification to facilitate the import and management of APIs. For example, the Apache APISIX Dashboard can import relevant route data through OpenAPI documents.

3. For the API ecosystem, the API marketplace can foster collaboration and innovation, inspiring new use cases and generating value by bringing together API suppliers and consumers.

6. Rise of More API Protocols​

With the rise of next-generation API protocols such as GraphQL and gRPC, which are competing with the current dominant but gradually declining REST API, more and more API protocols are being widely used.

GraphQL is a data query and manipulation language developed by Facebook. It allows clients to explicitly request the required data based on their needs and obtain multiple resources in a single request, reducing data transmission and improving performance. Compared to REST API, GraphQL has the following advantages:

1. Flexible data requests: Clients can specify the data they need, avoiding excessive or insufficient data transmission.
2. More efficient request processing: Retrieving multiple resources with a single request helps to reduce network round trips.
3. Real-time data updates: GraphQL supports real-time data updates and can respond promptly to clients' data change needs.

gRPC is a high-performance, open-source remote procedure call (RPC) framework developed by Google. It allows clients to call server-side methods as if they were calling local methods. gRPC uses Protocol Buffers (Protobuf) as the interface definition language and data serialization format, enabling efficient data transmission. Compared to REST API, gRPC has several advantages:

1. gRPC uses Protobuf for data serialization, which offers higher performance and smaller data size than JSON format.
2. gRPC is based on the HTTP/2 protocol, supporting bidirectional streaming, multiplexing, and built-in TLS security. This makes it faster, more flexible, and more secure than REST API based on the HTTP/1.1 protocol's one-way request-response mode.
3. gRPC defines APIs based on Protobuf and provides native code generation functionality. It can automatically generate client and server-side code in multiple programming languages, making it more convenient and consistent than REST API, which requires third-party tools like Swagger to generate code.

In order to accommodate the needs of emerging protocols, Apache APISIX offers a range of plugins designed to support the processing of different protocols.

In Apache APISIX, the following plugins can handle these emerging API protocols:

• grpc-transcode: grpc-transcode facilitates conversion between HTTP and gRPC requests.
• grpc-web: grpc-web is a proxy plugin that processes gRPC Web requests from JavaScript clients to a gRPC service.
• degraphql: degraphql is a plugin that supports the decoding of RESTful APIs into GraphQL.

7. Artificial Intelligence and APIs​

API management platforms are leveraging machine learning and artificial intelligence to automate tasks such as API discovery, threat detection, and anomaly detection. This can help enterprises reduce the burden on their IT teams and improve the efficiency and accuracy of their API management processes.

1. Threat detection: Machine learning and artificial intelligence can assist API management platforms in real-time monitoring and analyzing API traffic to detect and prevent any malicious or abnormal requests.
2. Anomaly detection: Machine learning and artificial intelligence can help API management platforms predict and diagnose any potential issues that may affect API performance or availability, facilitating timely repair and optimization.

8. Greater Focus on Developer Experience​

As APIs become increasingly central to business operations, developer experience has become increasingly important. API management platforms are adding more developer-friendly features, such as documentation, testing tools, and SDKs, to make it easier for developers to use APIs.

1. Documentation: Documentation is the primary way for developers to understand and learn about an API, so it should describe the API's functions, parameters, examples, error codes, and other information clearly, completely, accurately, and in a timely manner. Documentation should also provide interactive consoles or sandboxes that allow developers to quickly test and debug APIs.
2. Testing tools: Testing tools are an essential means for developers to verify and optimize APIs, so they should support a variety of testing scenarios and requirements in a convenient, reliable, and flexible manner. Testing tools should also provide real-time feedback and reports so that developers can identify and resolve issues in a timely manner.
3. SDKs: SDKs are a convenient way for developers to integrate and use APIs, so they should cover a variety of mainstream programming languages and platforms and stay in sync with API updates. SDKs should also follow best practices and standards to make it easy for developers to understand and call APIs.

9. The Rise of API Analytics​

API Analytics is a technology used to collect, analyze, and interpret data on API usage. With the growing popularity of APIs in the software and internet industries, API Analytics has emerged as a critical tool for management and optimization. Here are a few reasons for the rise of API Analytics:

1. With the development of technologies such as cloud computing, big data, and the Internet of Things (IoT), APIs have become an important tool for exchanging data and functionality between enterprises and developers. This has led to a growing need for API Analytics to better understand and optimize API performance.
2. Modern software development increasingly adopts a microservices architecture, which decomposes complex applications into multiple independent and scalable services. These services communicate with each other via APIs, making the need for API Analytics more apparent in this architecture.
3. API Analytics can help detect potential security vulnerabilities and violations of compliance, thereby reducing risk.

10. More APIs Are Provided Through Serverless Architecture​

Serverless architecture is a cloud computing model that allows developers to deploy and run applications without managing servers.

To provide API services through serverless architecture, you only need to follow a few steps:

1. Choose a serverless platform, and write your API logic code using the programming languages and frameworks provided by the serverless platform.
2. Configure your API triggers on the platform, such as HTTP requests, timers, events, etc.
3. Deploy your API code to the serverless platform using the relevant tools provided by the platform and test its functionality and performance.

Using serverless architecture has the following advantages:

1. Serverless architecture allows API developers to focus on business logic without worrying about infrastructure, deployment, scaling, etc.

2. Serverless architecture can automatically allocate resources according to API request volume, avoiding resource waste or shortages.

3. Serverless architecture can improve API response speed and reliability by leveraging distributed edge computing nodes to process requests.

Apache APISIX also supports this area, including plugins such as serverless and openfunction.
