What is a primary benefit of keeping search requests inside the Azure datacenter boundary?

One of the primary benefits of keeping search requests inside the Azure datacenter boundary is that it eliminates the costs associated with data transfer. When data is transferred out of the datacenter, there are usually charges applied based on the volume of data moved. By keeping search requests and data retrieval within the boundaries of the Azure datacenter, organizations can avoid these additional costs, leading to more cost-effective operations, especially when dealing with large datasets or frequent queries. This practice helps to streamline budgeting and financial management for applications that rely heavily on data-access activities.

In addition to cost savings, this approach can also potentially enhance performance due to reduced latency, as data doesn't need to travel over the internet, but the focus here is primarily on the billing aspect related to data transfer.
