In which migration strategy might an organization choose to break a monolithic application into microservices?
- Lift and Shift
- Rearchitect/Rebuild
- Refactor/Re-architect
- Rehost/Replatform
The "Refactor/Re-architect" strategy involves restructuring the existing application to make it more suitable for the cloud. Breaking a monolithic app into microservices falls under this category.
A group of non-profit organizations focused on wildlife conservation wants to share resources and data in a cloud environment without making it accessible to external entities. What type of cloud model should they consider?
- Private Cloud
- Public Cloud
- Hybrid Cloud
- Community Cloud
To ensure data privacy for non-profit organizations sharing resources in a cloud environment, a "Private Cloud" is the best option. It offers exclusive control over data and resources, making it inaccessible to external entities.
What is the primary difference between a Docker image and a Docker container?
- Containers are lightweight, images are heavy
- Images are for building, containers are for running
- Images run applications, containers store data
- Images store runtime data, containers store source code
Docker images are read-only templates used to create containers. Containers are instances of images that run applications. Images are for building and containers are for running.
In the context of Google Cloud Functions, what is the significance of "idempotent retries"?
- Ensuring reliability
- Handling cold starts
- Implementing triggers
- Reducing billing costs
"Idempotent retries" ensure that even if a request is retried, the system remains in a consistent state, essential for maintaining data integrity and reliability.
Community clouds are primarily designed to address the needs of:
- A specific industry or community
- Government agencies
- Individual consumers
- Large multinational corporations
Community clouds are designed to serve a specific community or industry, enabling them to share resources and comply with specific regulations and standards.
Azure's managed Kubernetes service is abbreviated as ________.
- A-Kube-Service
- AKS
- Azure Kube-Manager
- K8S
Azure's managed Kubernetes service is abbreviated as AKS, which stands for Azure Kubernetes Service. It simplifies deploying, managing, and scaling containerized applications using Kubernetes.
One of the primary benefits of using cloud-based analytics tools like AWS Redshift or Google BigQuery is the ability to scale ________.
- Elastically
- Horizontally
- Statically
- Vertically
Cloud-based analytics tools provide the ability to scale "elastically" by dynamically adjusting resources to meet demand, a key feature for handling varying workloads.
Docker ________ allows users to define and manage multi-container Docker applications.
- Compose
- Engine
- Hub
- Swarm
Docker Compose is the tool that allows users to define and manage multi-container Docker applications. It uses a YAML file to configure the services.
________ is a popular tool used for managing and orchestrating containerized applications, making it essential in CI/CD pipelines that utilize containers.
- Docker Compose
- Jenkins
- Kubernetes
- Terraform
Kubernetes is a widely used container orchestration tool. It's crucial in CI/CD pipelines to deploy, manage, and scale containerized applications efficiently.
Which of the following benefits can be attributed to the microservices architecture?
- Decreased development speed, high coupling between services, and centralized control
- Enhanced monolithic architecture, simplified deployment, and limited fault tolerance
- Improved scalability, fault isolation, and easier maintenance
- Reduced code reusability, lack of service independence, and slower time-to-market
Microservices offer various benefits, including improved scalability, fault isolation, and easier maintenance. This architecture allows for independent service scaling, enhancing the application's overall performance and reliability.
