Process applications
In Web Modeler a process application is a type of folder that contains a set of related files you can work on and deploy as a single bundle.

For example, a process application for a consumer loan application might consist of a BPMN diagram as an entry point and a number of additional supporting files, such as DMN diagrams and forms.

Process application development lifecycle
In Web Modeler, you can quickly develop and progress low-risk process application releases through the stages of a typical development lifecycle.
Create a process application
Get started by creating a new process application.
- When you create a process application, you must select a cluster to use for deployment during development.
- You can add files to the process application as required.
Validate and deploy your process application
Validate your process application in development before deploying it to testing, staging, or production.
Process application versioning
Use versioning to save a single snapshot of all the process application files in one action.
Known limitations
You should be aware of the following limitations when working with process applications.
General limitations
- Self-Managed does not support defining cluster stages, identifying clusters by tags, or cluster promotion.
Deployment limitations
- Process applications can only be deployed to a Zeebe cluster in version 8.4.0 or higher.
- The overall size of the deployment bundle is limited due to a maximum record size of 4 MB in Zeebe.
- The limit is effectively between 2 and 3 MB, as Zeebe writes more data to the log stream than just the raw deployment.
- If you exceed the limit, you are shown an error message:
Command 'CREATE' rejected with code 'EXCEEDED_BATCH_RECORD_SIZE'.
