Applications have historically been deployed and created in a manner reminiscent of classic shopping malls. First, a developer builds the mall, then creates the various stores inside. The stores conform to the dimensions of the mall and operate within its floor plan.
In older approaches to application development, a developer would have a targeted system or set of systems for which they intend to create an application. This targeted system would be the mall. Then, when building the application, they would tailor it to fit within the confines of the targeted system, like the store in the mall.
Historically, however, problems have arisen with this approach. What if I want to deploy a store within a mall but the store doesn’t fit within the confines of the mall floorplans? The same principle applies to applications. What happens if I want to deploy an application to a system it wasn’t designed to target? Usually, it won’t work.
The retail industry came up with a creative solution to the misfit brick-and-mortar store problem — e-commerce. With websites, items could be sold that didn’t fit in physical storefronts. Similarly, the technology sector has a solution for the application misfit problem — containerization.
What is Containerization?
With containerization, developers and engineers can distribute an application as a package that contains the required operating system components for the application. This allows engineers and developers to create applications without the concern about whether an application will successfully deploy to a custom operating system or platform. Because containers usually only include the required components and files of their contained application, ..
