Pega Cloud 2.3 supports node classification per Pega 7.3, hence starting Cloud 2.3 versions the BIX agents runs on UTIL node. There is NO seperate node available for BIX.

It needs to be highlighted that there are three key differences between a customer running BIX on-site versus running BIX on a Pega Cloud instance:

• Output format options for extracted data are limited to either XML or CSV files. Writing extracted data directly to a database is not supported on the cloud.
• Direct access to the Pega Cloud server file system is not allowed, and BIX cannot be run from an external command-line process.
• Direct access to the Pega Cloud server file system is not allowed, and the extracted files must be transported to a customer FTP site. All extracted files from a BIX run are compressed and delivered as a single ZIP file whose name consists of classname, extractname and sequence number.
