Answer 1

Docker, Inc. is a software company based in San Francisco, California which produces the Docker software.

 

It is a computer program that executes containerisation. Containerisation is OS (Operating System) level virtualisation, which allows independent containers to run within single Linux instance, instead of having several virtual machines.

 

Its main features are:

 

·         Allows flexibility to change existing application portfolio, extending the life of legacy systems.

 

·         Developers and IT operators can work on the same platform, their synergies resulting in better output.

 

·         It provides an integrated security framework, thereby delivering safer applications and realistic automation of policies.
