hi, I'm building some "Good practices" guidelines.
For SSIS, I prefer keeping the package files on the database server under a folder named "SSIS Packages". And they don't reside in folders that are someone's name. This way, when a developer leaves, nothing has to be moved etc.
I want to check with other professionsal to get your opinions on the best options for storing the SSIS package files.
you can store it in msdb folder by importing packages to integration services instance. Keep the protection level of packages to rely on server storage. The deployment utility can be created from visual studio project which will create a manifest file which you can click and do the deployment yourself in the required server.
