Docker Containers v/s Virtual Machines

Docker

  - Application Delivery Technology
  -  Build an application with a Docker Image
  - Ship an application with Docker Hub
  -  Run an application with Docker Container
  - Avoid single point of failure

Docker Compose

   Defining and Running multi-container Applications.

   - Configuration defined in one or more files

   docker-compose.yml(default)

   docker-compose.override.yml(default)

   Multiple files specified using -f

   All paths relative to base configuration file

- Great for dev, staging, and CI

 Docker Swarm

  Native clustering for Docker

  Provides a unified interface to a pool of Docker hosts

  Fully integrated with Machine and Compose

  Serves the standard Docker API

  1.2 - Ready for Production

    - Reschedule containers when a node fails

    - Better node management

Differences between docker containers and virtual machines can be measured based on the operating system support, security, portability, and performance

Difference between BindingContext and BindingContainer in ADF

BindingContext is a container Object that holds a list of available data controls and data binding objects.It is the Java representation
of all cpx files marked in your adfm.xml file

BindingContext class is an interface that exposes generic methods to access the binding layer


The BindingContainer class represents Java representation of the page definition file.
To read bindings or executable entries present in the page definition we may need to access binding container object.

BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
