ZhongAn's Business Characteristics

Diverse Insurance Offerings

ZhongAn Insurance boasts many insurance categories that span a wide spectrum, including vital ones like property insurance. Each category comes with its own distinct characteristics, regulatory considerations, and customer demands. Moreover, the diverse nature of insurance types often entails distinct underwriting, claim procedures, and risk evaluations. These disparities require a comprehensive and meticulous approach to management.

Multifaceted Operational Approach

As an internet-based insurance company, ZhongAn Insurance conducts all its operations online. It capitalizes on the inherent advantages of online traffic while managing numerous offline and traditional insurance aspects. More specifically, since ZhongAn Insurance depends on various channels for many of its service entry points, the company is actively pursuing enhanced business management by strengthening its control over traffic from these diverse channels.

Rigorous Regulatory Oversight

Operating in a sector that directly interfaces with financial transactions, the insurance industry falls within the purview of national financial regulators. Like banks and securities firms, insurance products come under the country's vigilant scrutiny, mandating strict adherence to industry-specific regulations. Annually, ZhongAn Insurance is required to align with the country's regulatory and developmental needs, including both business and technological aspects.

Pain Points Before Using APISIX

As ZhongAn continues to advance its business, it becomes increasingly clear that several challenges emerge in the realm of ecosystem integration and gateway management.

Limited Ecosystem Integration

ZhongAn Insurance grappled with several significant operational challenges.

  • Deployment Across Diverse Environments: The company faced obstacles when deploying the same application or service across different environments.

  • Phased Software Release in Production: It also struggled with implementing a gradual release of new software versions in the production environment, which could potentially lead to disruptions and issues.

  • Inadequate Isolation Between Environments: The absence of adequate isolation between distinct computing environments or domains created a situation where ensuring seamless functionality became challenging, resulting in possible interference and conflicts.

  • Challenges in Multi-Cloud Management: In the context of a multi-cloud environment, managing and resolving issues proved to be an ongoing challenge, impacting the efficiency and reliability of their cloud-based operations.

Unclear Gateway Positioning

The blurring of lines between technology and business within the gateway infrastructure introduces confusion and complications. When the boundaries between the two are not well defined, gateways often become repositories for an excess of business logic. This scenario has not only complicated the gateways' operations but also made them challenging to manage and maintain efficiently.

Multiple Gateway Choices Within ZhongAn

Within ZhongAn, different departments have frequently chosen varying gateway solutions. This diversity has introduced challenges in maintaining a uniform approach throughout the organization, as each gateway typically requires dedicated efforts for development and maintenance, leading to inefficiencies in time and resource management.

Governance Complexities

The diversity of gateways resulted in inconsistent implementation of monitoring, alerting, authentication, and authorization mechanisms. This inconsistency could pose some challenges to maintaining a unified approach to security and operations. Without a standardized governance framework, ensuring seamless operation across the gateways was a complex and demanding task.

Therefore, to address the complex business scenarios and industry-specific characteristics of ZhongAn Insurance, there is a strong need for effective traffic governance on the technical side.

Why ZhongAn Opted for APISIX

In a comprehensive technology selection process, ZhongAn Insurance carefully evaluated a range of renowned open-source products available in the market, including Kong, Traefik, APISIX, and Alibaba Cloud MSE. After careful consideration, the enterprise ultimately chose APISIX, drawn to its distinctive advantages:

Implementation of APISIX

Charging Based on Usage for BaaS Products

ZhongAn Insurance is progressively transitioning its core products into a backend-as-a-service (BaaS) model. Since these products offer insurance services with financial attributes, they entail more rigorous deployment requirements, prompting the need for a unified standard that covers both infrastructure products and cloud-based services for measurement and billing.


APISIX's authentication service plays an important role in providing real-name verification and vital auditing functionalities. This function ensures that all in-house products at ZhongAn Insurance align with the regulatory requirements typical of financial reporting. Besides, the robust logging capabilities of Apache APISIX enable comprehensive tracking of all internal transactions within the organization, including metrics like call frequencies and associated costs.

ZhongAn Insurance has also harnessed APISIX to present crucial metrics, gaining a good command of parameters such as API calls and peak usage. These metrics facilitate the calculation of peak audits through billing formulas.


The configuration center operates on layer 7 protocols, seamlessly integrating them into the measurement and billing system, which includes ElasticSearch (ES) and APISIX. In practical terms, this entails defining actions within the current APISIX structure to meet various company-specific business requirements and leveraging APISIX plugins to effectively implement orchestration capabilities.

Traffic Isolation Across Multi-Tenancy and Channels

With its extensive array of insurance products and diverse distribution channels, ZhongAn Insurance has identified a critical need for multi-tenant and multi-channel traffic isolation. Harnessing the power of APISIX, the company has gained unprecedented precision in controlling traffic, a capability that is indispensable in the dynamic landscape of internet-based insurance.

In some cases, when a project is big and has a significant flow of traffic within its channels, a dedicated cluster is set up for each channel. However, for smaller projects with lower overall channel traffic, the approach is to try merging these smaller channels into a single gateway entity or instance for shared usage.

Due to variations in integration processes and different upstream and downstream requirements, each application's integration leads to the creation of a unique domain name. This form of isolation, as depicted in the structure below, is referred to as first-level isolation.


Following the channel integration, there is a subsequent need for specific operations. Despite similar procedures, the subsequent phase demands distinct business control capabilities, distinct from first-level isolation. This scenario calls for the implementation of second-level isolation for channels, as indicated in the diagram.


By deploying a combination of first-level and second-level isolation, ZhongAn Insurance has successfully tackled the challenge of traffic isolation within its multi-tenant, multi-channel gateway environment.
