Workday provides a number of offerings. I've seen it primarily being used for human capital management, which includes onboarding, the entire employee lifecycles from recruiting to offboarding, payroll, benefits, absence, and time tracking.
Unlike some of its competitors such as PeopleSoft, Oracle, or SAP, Workday is cloud-based. Workday is built natively in the cloud, and you're always on the most recent version.
In terms of the cloud provider, they do have their own data centers. They've got one in Portland. They've got one in North Carolina, one in Dublin, Ireland, and maybe one or two at other places. I have heard that ultimately the underlying technology is AWS, but I'm not certain of that.
Technically, it's a hybrid model. Their enterprise bus model is such that technically you share server resources with other customers. A lot of customers don't actually know that, but if we're all running a lot of integrations or doing a lot of data processing at once, it's possible that the server could be impacted, and whoever is providing the maintenance would have to then throttle and pull resources from somewhere else. However, most customers don't experience any type of real performance issues, and then from a security standpoint, even though they're shared server resources, everything is of course constrained to just that particular customer. No other customer could view a separate customer's data or things of that nature.
