Your agency provides career services throughout a large urban area and you cater to the legal and financial community where proof of delivery, timeliness, and package tracking are critical requirements. You're working with the business partner to upgrade your company's Courier service software with the goal of posting this software in the cloud and making a mobile app available to the client for real$-$time updates and legally$-$defensible documentation.

Partner: "Using a cloud based software is a great move for us so we can incorporate in mobile app. What other technical level changes are we looking at$?"$

You: "For one, the software relies on $$ so each transaction or update to a record occurs right away instead of waiting for a group update. This will offer more up$-$to$-$date information as packages traveled across town."
