Companies adopting Public and Hybrid Cloud environments often lack the portability they need to deploy applications across various Infrastructure Platforms.
As applications move from development, testing ,staging and production, issues can occur within the application delivery process which places a strain on resources.
Docker changes this paradigm and has opened up hybrid cloud computing to companies of all sizes. Applications can be transported from development, test and production and the code will work as designed every time regardless of the underlying infrastructure .
Any differences in the infrastructure environment does not affect the application inside the container. And the application does not need to be modified to work in production. This is a boon for IT operations teams as they can now move apps across data centers for clouds to avoid vendor lock in.
This has opened a new world around Cloud Federation, allowing companies to adopt the right infrastructure platform, whether inside or outside their data center.
