Data integration solutions come in one of three categories. First there’s old school data integration solutions created in the 1990s from the EAI movement, now expanded to include public cloud computing domains. Second, newer cloud-based iPaaS (integration platforms as a service) solutions built from the ground up as on-demand integration servers hosted on the open Internet, but existing outside of public cloud providers. Third, data integration solution existing within public clouds, which are typically more primitive. However, these native services are easily deployable from inside a public cloud provider.
