Kubernetes Basics, Benefits, Architecture, and Components

What is Kubernetes?

• Kubernetes is an open-source container orchestration platform.

• Kubernetes is a hardware device

• Kubernetes is a programming language

• Kubernetes is a type of database management system

List three benefits of using Kubernetes.

• Automated scaling, self-healing capabilities, efficient resource utilization

• Manual scaling, limited resource utilization, slow deployment process

Explain the architecture of Kubernetes.

• Kubernetes architecture does not involve any master node

• Kubernetes architecture only includes worker nodes without a master node

• Kubernetes architecture consists of a single node handling all tasks

• Kubernetes architecture comprises a master node and multiple worker nodes, each with specific components responsible for managing and running applications within the cluster.

Name three key components of Kubernetes.

• Containers

• Pods, Nodes, Services

• Namespaces

• Volumes

What is the role of a Pod in Kubernetes?

• A Pod in Kubernetes is the smallest deployable unit that can run multiple containers.

• A Pod in Kubernetes is a type of cloud storage

• A Pod in Kubernetes is a type of fish

• A Pod in Kubernetes is a type of programming language

How does Kubernetes help in scaling applications?

• Kubernetes provides features like horizontal scaling, auto-scaling, and load balancing to easily increase or decrease the number of running instances of an application based on demand.

• Kubernetes scaling is limited to a fixed number of instances and cannot be adjusted dynamically.

• Kubernetes helps in scaling applications by providing features like vertical scaling, manual scaling, and single instance deployment.

• Kubernetes does not support scaling applications, it is only used for container orchestration.

Describe the role of a Service in Kubernetes.

• The role of a Service in Kubernetes is to schedule and orchestrate containerized applications.

• The role of a Service in Kubernetes is to manage storage volumes for Pods.

• The role of a Service in Kubernetes is to provide a stable network endpoint to access a set of Pods.

• The role of a Service in Kubernetes is to monitor the health of the Kubernetes cluster.

What is the significance of a Kubernetes Controller?

• Kubernetes Controller is significant for managing and maintaining the desired state of the cluster.

• Kubernetes Controller is responsible for network security

• Kubernetes Controller is used for data analysis

• Kubernetes Controller is designed for front-end development
