Microsoft Azure Architect Technologies (AZ-300) Practice Exam

Which technology is commonly used for containerization in Microsoft Azure?

1. VMware

2. Docker

3. Hyper-V

4. Red Hat

The correct answer is: Docker

Docker is the technology commonly used for containerization in Microsoft Azure. It allows developers to automate the deployment of applications within lightweight, portable containers that can run consistently across different computing environments. Docker containers encapsulate an application and all its dependencies, facilitating easy movement between development, testing, and production environments. In Azure, Docker is integrated smoothly with various services and orchestration tools like Azure Kubernetes Service (AKS), which simplifies the management and scaling of containerized applications. The popularity of Docker stems from its efficient resource usage, reduced overhead compared to traditional virtual machines, and its support for microservices architecture, making it particularly appealing for cloud-native development. Other technologies, while relevant in the context of virtualization and container management, do not serve as the primary method for containerization on Azure. VMware, for instance, is primarily used for virtualization rather than containerization, and Hyper-V, a virtualization platform, focuses on creating and managing virtual machines. Red Hat offers container solutions as well (e.g., OpenShift), but Docker is the foundational technology most closely associated with containerization itself in the Azure ecosystem.
