What is an important difference between containers and virtual machines?
- A. Containers virtualize the operating system and VMs virtualize the hardware
- B. Containers virtualize hardware and VMs virtualize the operating system
- C. Containers virtualize the operating system and VMs virtualize the registry
- D. VMs virtualize the hardware and Containers virtualize the registry
正解: A
解説:
Containers are lightweight and portable executable units (images) of software. They supply portability between different platforms and clouds. Containers are self-contained units that are designed to hold applications as well as all libraries and dependencies that the application requires. Containers can be run on physical computers or in the cloud.
Containers do not have an operating system of their own. Instead, they access the operating system of the device they are running on using a hypervisor. This allows them to be more light-weight, easier to provision, and much smaller than traditional virtual machines.
Virtual machine is a virtual re-presentation of physical computer, you can understand it as a computer inside a computer. Each individual virtual machine behaves exactly as though it were its own computer. It has its own operating system, memory, storage, and compute and is totally unaware of other virtual machines that could be running on the same host.
How do containers differ from a traditional VM?
Traditional virtualization leverages a hypervisor to virtualize physical hardware. Each VM contains:
- A guest operating system (OS)
- A virtual copy of the hardware that the OS requires to run
- An application and its associated libraries and dependencies
- Containers, on the other hand, virtualize the operating system. Each container only contains:
- The application
- Its libraries
- Its dependencies

What is an example of cloud native application built with a microservice approach?
- A. An application developed using IBM Cloud hosted integrated development environment and deployed to production on a locally hosted virtual machine.
- B. A software platform available exclusively on IBM Cloud
- C. A containerized application that is deployed on an Orchestrated platform
- D. A window's application designed to run both on IBM cloud and on locally hosted environments
正解: C
解説:
Cloud native refers less to where an application resides and more to how it is built and deployed. Most organizations using containerized microservices also use a container orchestration platform, such as kubernetes, to automate container deployment and management at scale. Cloud native applications are built to operate only in the cloud. Developers design cloud native applications to be scalable, platform agnostic, and comprised of microservices.
