How can cloud-native development environments be integrated with existing legacy systems?

Cloud-native development environments are based on containerization (such as Docker) and microservice architectures, enhancing the agility and scalability of applications; legacy systems refer to traditional monolithic applications or data sources. Integration is crucial for business continuity and hybrid cloud transformation, with application scenarios including progressive modernization in financial services or manufacturing to ensure data consistency.

Core components include API gateways and service meshes (such as Istio), which encapsulate legacy components using Kubernetes service discovery and namespace isolation. The principle is to bridge old and new systems through adapters or event-driven patterns to achieve microservice interoperability. The practical impact is reducing integration risks and facilitating innovation paths.

Phased implementation: Assess dependencies, package legacy applications into container images; develop RESTful API or message queue adapters; deploy to Kubernetes clusters and configure service mesh rules. A typical scenario is CRM system upgrades, with business values including reduced migration costs and improved development efficiency.
