We're doing integrations ourselves. We looked at iPaaS for a long time, but we started doing a lot of this integration before there were good iPaaS solutions on the market that were affordable. The middleware is not that hard, but the key is the talent of the team to do this. We are finding that we're building some centralized databases, SQL tables, that happen to have a lot of the crosswalk data we need to make all the things talk to each other. The team that was doing that ad hoc is now formalizing the process and saying, "We're going to have this middleware database that simply pulls pieces from all the places we need it, to be able to look elsewhere." It's proving to be transformative. And it's stopping a lot of our clients from looking for cloud solutions that fit their needs because we can bring something together a lot quicker using pieces they already know.
