Instead, we rely on landing fees, the rent we receive from tenants, and a percentage of the profits from concessions-the restaurants, newsstands, and other shops located in the airport-to fund our growth. And like every business, we're constantly looking for ways to bring down our costs by operating more efficiently. We evaluated a lot of technologies to help us trim costs, but we selected Office 365 because it not only saves money, it gives us what we need to meet future IT demands. With our eyes on current and future needs, we did some modeling to gauge regional demand for our airport services over the next decade. It quickly became clear that we needed to add runways, terminals, and other "bricks and mortar" facilities, and upgrade our network infrastructure. Still, the only way we could budget for that expansion was to reduce or eliminate some of our fixed capital costs. I knew that one important way we could trim expenses was by taking a closer look at the technology we use and how we manage it. Our email system offered a prime example of how, by rethinking the way we deliver core IT services, we could cut down on operational "drag" and potentially save our IT team lots of time. Historically, we've managed our email in a clustered environment across four physical servers. So, we were not only worrying about the cost of the servers; we had to invest in mirroring software and an antivirus so
