Before we jump into the details, let’s answer the question: “What is cloud integration architecture?” Cloud integration architecture is the combination of the cloud components and several cloud providers that allows exchanging of data across several data centers.
For example, imagine that we have a large banking solution. Some banks don’t want to migrate their core and secured data. They want to keep it in their on-premises data centers. However, they can’t avoid using clouds. They migrate existing projects, new projects that are starting, and even the whole call centers and back office to the cloud. Building this complex architecture requires knowledge of the integration service and tools that the clouds provide.
