If you've got core business solutions and applications that rely on an uninterrupted bilateral or multilateral flow of information and data to operate effectively, you'll need an integration solution to help them talk to each other.
Whether your applications are on-premises, in the cloud, or a combination of both, the IaaS delivery model allows your partner (or, in the case of iPaaS - your internal team) to build, manage, update, and maintain them in the cloud. So, you always achieve always-on, secure, end-to-end value extraction from your investments.
