The implementation of cloud-native applications is usually based on the micro-service architecture. Which of the following descriptions about the underlying technology of the micro- service…

Question

Options

• ANon-intrusive service governance can be achieved through Istio
• BAgile infrastructure can be realized through unified scheduling of OpenStack resources
• CContinuous development and integration can be achieved through the microservice framework
• DContainerized deployment can be realized through Kubernetes container orchestration and

• A
  84% (52)
• C
  16% (10)

Explanation

Istio is a service mesh that injects sidecar proxies alongside application containers to handle traffic management, security, and observability without changing application code, making A correct for non-intrusive governance. OpenStack provides unified scheduling and management of compute, storage, and network resources, enabling the on-demand, scalable infrastructure that defines agile cloud environments, making B correct. Kubernetes automates the deployment, scaling, and management of containerized workloads, directly enabling containerized deployment as described in D. Option C is wrong because continuous development and integration is the domain of CI/CD pipelines and tools such as Jenkins or GitLab CI, not the microservice framework itself; the microservice framework handles concerns like service discovery, communication, and resilience, not build and release automation.

Memory tip: Match each tool to its layer - Istio governs traffic between services (service mesh layer), OpenStack manages the raw infrastructure (IaaS layer), Kubernetes orchestrates containers (container layer), and CI/CD tools handle the development pipeline (delivery layer). C fails because it assigns a delivery-pipeline responsibility to an application-framework tool.
