This document discusses different approaches for deploying SSIS packages and projects. It describes the traditional "copy and configure" approach where packages are copied to shared locations and configurations are stored separately. This can cause issues when environments are restored from backups. The document then introduces SSISDB, the new catalog database in SQL Server 2012 that centrally stores packages, projects, configurations and metadata to simplify deployment. It provides an overview of the steps to create an SSISDB catalog and deploy SSIS projects through the catalog.
