When discussing end-to-end solutions with customers, we often explain that blockchain-related components represent a very small percentage of the overall footprint. This is still a very important set of components, but nonetheless they represent a small footprint.

This section will focus on the touch point between our traditional systems and the Hyperledger Fabric and Composer API.

We will explore the various patterns of integration we have leveraged and see how some of the non-functional requirements can influence the integration deployment. Finally, we will explore some additional considerations that integrators will need to keep in mind when designing their integration layer.

In short, in this section, you will:

• Understand the design consideration of the integration layer
• Review the integration design patterns
• Explore the impact of non-functional requirements on the integration
