CPI (Cloud Platform Integration) and Integration Suite are both integration platforms offered by SAP. While there is some overlap in functionality, there are some differences between the two.

CPI is a cloud-based integration platform designed to connect cloud applications with each other and with on-premise systems. It provides pre-built connectors and adapters for popular cloud applications and supports a wide range of integration patterns, including real-time data synchronization, message routing, and data transformation. CPI also includes a visual development environment and a variety of monitoring and management tools.

On the other hand, Integration Suite is a more comprehensive integration platform that includes CPI, as well as other integration tools, such as API Management and Open Connectors. Integration Suite is designed to support a wide range of integration scenarios, including B2B integration, IoT integration, and hybrid integrations that span cloud and on-premise systems. Integration Suite provides more advanced capabilities for managing API lifecycles, building event-driven architectures, and handling complex data transformations.

In summary, CPI is a cloud-based integration platform focused on connecting cloud applications and on-premise systems, while Integration Suite is a more comprehensive integration platform that includes CPI and additional tools for supporting a wider range of integration scenarios.
