Master Microservices with Spring Boot and Spring Cloud - Step 01 – Getting Started with Docker, Kubernetes, and Google K

The video tutorial introduces Docker and Kubernetes, highlighting Docker's ability to standardize application deployment across different environments. It then transitions to Kubernetes, showcasing its powerful features like scaling, load balancing, and resilience. The tutorial also covers advanced Kubernetes operations, such as zero downtime updates, and discusses its cloud neutrality, emphasizing the use of Google Kubernetes Engine (GKE) for managing clusters.

What is one of the main advantages of using Docker for application deployment?

• It only supports applications written in Java.

• It allows applications to run without concern for the underlying infrastructure.

• It requires specific hardware configurations.

• It is only compatible with cloud environments.

Why might Docker alone not be sufficient for managing large-scale applications?

• Docker requires manual configuration for every deployment.

• Docker cannot handle application scaling and load management effectively.

• Docker is not compatible with cloud environments.

• Docker does not support multiple programming languages.

What is a Kubernetes cluster?

• A single server running multiple applications.

• A group of servers managed together to run applications.

• A cloud service for storing application data.

• A tool for monitoring application performance.

How does Kubernetes handle load balancing?

• By limiting the number of requests to each instance.

• By automatically distributing load among available instances.

• By using a third-party load balancer.

• By manually distributing requests across servers.

What feature of Kubernetes allows it to maintain application uptime even if an instance fails?

• Manual instance restart.

• Automated instance recovery.

• Scheduled maintenance windows.

• Instance duplication.

How does Kubernetes handle application version upgrades?

• By shutting down the application during the upgrade.

• By running both versions simultaneously and gradually shifting load.

• By replacing the old version with the new one immediately.

• By requiring manual intervention for each instance.

What is the benefit of Kubernetes being cloud neutral?

• It can only run on Google Cloud.

• It allows applications to be deployed on any cloud provider.

• It requires specific cloud configurations.

• It limits the scalability of applications.

What is Google Kubernetes Engine (GKE)?

• A tool for developing Kubernetes applications.

• A managed service for running Kubernetes clusters on Google Cloud.

• A monitoring tool for Kubernetes clusters.

• A database service for Kubernetes applications.

What is one of the challenges of setting up Kubernetes?

• It cannot be used in cloud environments.

• It only works with Docker containers.

• It is difficult to create and manage Kubernetes clusters.

• It requires a specific programming language.

What infrastructure does GKE use to run its services?

• The same infrastructure that Google uses for its services.

• Dedicated hardware for each user.

• A third-party cloud provider.

• A local server setup.
