Currently iText DITO is architected on 2 different parts, first the DITO SDK and second the template Editor + template Manager. This 2 parts are delivered in 2 different docker containers (SDK also available as JAVA project) to give flexibility to our customers.
The biggest advantage of using containers is that DITO is platform-independent. The containers should already contain everything that DITO needs.
This will allow you to run your application on any environment you want.
