Kubernetes and Cloud Native Associate (KCNA)Cloud Native ArchitectureMedium
A cloud-native application uses several microservices, each deployed as a container. To improve resource utilization and ensure high availability, these containers are orchestrated across a cluster of virtual machines. Which core cloud-native architecture component is responsible for managing and automating the deployment, scaling, and operation of these containerized applications?
- AAPI Gateway
- BContainer Orchestrator
- CLoad Balancer
- DService Mesh
Show answer & explanationAnswer & explanation
Correct answer: B. Container Orchestrator
A Container Orchestrator, such as Kubernetes, is specifically designed to automate the deployment, scaling, and management of containerized applications across a cluster of machines, directly addressing the scenario's requirements.
Why the other options are wrong
- A. An API Gateway handles incoming API requests and routes them to the appropriate microservices.
- C. A Load Balancer distributes incoming network traffic across multiple servers to ensure high availability and responsiveness.
- D. A Service Mesh provides capabilities like traffic management, security, and observability between services.
Container Orchestration
The automated management, deployment, scaling, networking, and availability of containerized workloads and services.
- Manages container lifecycles.
- Handles scaling up/down based on demand.
- Ensures high availability and fault tolerance.
Memory trick: Cloud's core: containers orchestrated, accessed via API, meshed for comms, balanced for load.
