IBM Bluemix中的容器是什么？

Question

This is my first question in Stack Overflow. I don't know if this is related to programming or not. But I don't know where to ask.

What is a container in IBM Bluemix? What is the difference between a container and a VM?

And do I need a container if I want to use IBM Bluemix services, such as the iot platform?

Welcome to Stack Overflow. This question is only indirectly related to programming. For the types of questions to ask on Stack Overflow, see What topics can I ask about here? in the Stack Overflow help.

You do not need to use containers to use the Bluemix platform and services, unless you have a specific need for them.

Briefly, Bluemix containers are built on Docker technology. They are a lightweight, portable infrastructure that enable you to run your app without alteration in a variety of runtime environments. They are similar to Virtual Machines, but lightweight in providing only the elements your app requires to run, and portable in being able to run anywhere - Windows, Mac, Linux, or in the cloud. For more details, see Getting Started with IBM Containers in the Bluemix docs.

Answer 2

In short :

Containers are virtual software objects that include all of the elements that an app needs to run.

IBM Containers are Docker containers in Bluemix, which is a hosted cloud environment.
