I'm diving into Azure Data Factory (ADF) for work and recently started learning about Linked Services. I've successfully connected to a single storage account, but now I'm exploring how to use parameters within these Linked Services for greater reusability and dynamism. I have a few questions: 1. How do parameters actually help make a Linked Service reusable in practical scenarios? 2. If we have multiple storage accounts (used by different teams), is it standard practice to create multiple Linked Services for each, or is there a more efficient way? I've heard that using a single Linked Service with parameters could be the way to go, but I'm unsure how that works, especially when it comes to the details needed for authentication, since we usually provide a storage URL and account key. How can parameterization help us connect to different storage accounts seamlessly? I'd appreciate any simple explanations or real-world examples to help clarify these points.

It's interesting because your second question actually answers your first one and vice versa! As for your last concern, you can definitely parameterize authentication too. It's typically best to use managed identities instead of keys, which would eliminate the need to parameterize them altogether.
I can't imagine working with ADF at any scale without applying parameters extensively, like for datasets, Linked Services, and triggers. You're on the right path!
