What is the difference between the Cloud and on-prem options?
With DOORS Next Generation on Cloud, IBM hosts and setup your software in the dedicated hosted environment for you to use. This is the best option for teams who want to get started quickly and without the hassle of going through implementation process, and specially for teams who do not want to manage the technical complexity of managing/hosting. This option enables you to take advantage of the tool quicker and helps you achieve ROI faster and shorten time to market for your products.
With DOORS Next Generation on premise, you host the software on your own hardware and you are able to customize your setup however you would like. This is a good option for teams who want to manage all the details of the setup and are fine with managing and hosting it themselves.
