With an application in the cloud, you have many points of integration: ✓ The application may integrate with a CRM application in your organization. ✓ The application may integrate with other services in the cloud. ✓ Enterprises that have invested in designing infrastructure with a service-oriented approach will be in the best position to integrate internal services with cloud services. ✓ Enterprises that have focused on taking existing infrastructure and wrapping key components so they can be exposed as services are ready to begin to integrate service in a hybrid environment. In order to make all this happen, the PaaS provider must have well-documented and well-defined interfaces for you to use. In other words, at the center of integration capabilities between applications in the cloud or on-premises are Application Programming Interfaces (APIs). These APIs, which are part of the PaaS platform, enable companies to quickly integrate their services into a wide variety of applications on a diverse set of platforms.
