We use it to schedule batch jobs. Batch jobs are a combination of SSIS jobs, which is actually our group's main use case. I brought it in mostly to schedule our SSIS batch jobs. Then, there are other groups who are using it for SQL Server stored procedures. We also have another group using it for a few Python scripts and FME, which is a different type of ETL tool. So, we are using JAMS to schedule those four types of jobs as well as a bunch of FTP jobs.
The application developers have been doing a combination of migrating some of their older jobs, like Python scripts and SQL stored procedures, and FME jobs over to JAMS. Any new batch jobs that they are creating default to using JAMS. They mostly do interactive online type applications. However, on occasions where they do need batch processes, they just use JAMS.
