DITA Open Toolkit Cloud Publishing
DITA Open Toolkit (DITA-OT) Cloud is a cloud-based integration between Heretto CCMS and the DITA-OT open-source publishing engine. DITA-OT Cloud is a cloud publishing engine that uses cloud computing to publish content in a secure, temporary cloud container. As a result, publishing operations do not affect the performance of the CCMS.
If you're interested in DITA-OT Cloud because you need to publish your content to PDF, you might want to consider using PDF Generator instead. PDF Generator is a more user-friendly publishing engine that uses CSS for output styling. Thanks to that, many teams can manage PDF output styling in-house without having to rely on consultants as it is often the case with DITA-OT.
This document doesn't explain how to develop a custom plugin. We can recommend partners who provide DITA-OT customization services.
DITA-OT Cloud Benefits and Overview
Because the Heretto DITA-OT Cloud is a cloud solution, your publishing jobs do not compete for memory and processing resources in the CCMS. The benefit is that the system does not slow down, even when you are publishing a large publication or to multiple languages or output types.
The DITA-OT Cloud publishing engine provides you with the following benefits:
- Publishing does not affect the CCMS performance as it happens in a separate space in the cloud
- You can have parallel publishing (available by default with select CCMS license types)
- Modern, Google Chrome™-compatible scenarios management interface
The default number of DITA-OT Cloud workers depends on the CCMS license type and is at least one worker. One worker can run one publishing job at a time which means that additional jobs are queued and processed one by one as the worker completes jobs. For example, if your publishing job on average takes four minutes to publish and you start three publishing jobs, with one worker the first job will complete at four minutes, the second at eight minutes, with the third job completing at 12 minutes from the start. DITA-OT Cloud enables you to use more workers to run more publishing jobs at the same time, increasing throughput. Using the previous example, if you have three workers enabled, all jobs would run simultaneously and complete in four minutes. You can purchase additional workers regardless of your CCMS license type.
