Enterprise Integration Patterns in Cloud Platform Integration (EIPinCPI)

December 15, 2019 Bhalchandra Wadekar

Hi SAP Community,


I want to contribute more to the SAP Community. Here’s an idea: why not blog about 65 integration patterns explained in Enterprise Integration Patterns book by Gregor Hohpe and Bobby Woolf and their implementation in SAP Cloud Platform Integration.


So, my resolution for 2020 is to blog about Enterprise Integration Patterns in Cloud Platform Integration. I aim to post a blog about an integration pattern every Sunday. I will call this project EIPinCPI. You can easily follow blogs in this series by following the tag EIPinCPI. Maybe, not all of the patterns can be implemented in CPI, maybe some of them can only be implemented partially, I’ll try my best to inform the same in my blogs.


Here’s the table of integration patterns [1]. I’ll link to individual blogs as I write them:

Why Patterns?

Now that we have index out of the way, let us explore a little bit about reasons to use Enterprise Integration Patterns (This paragraph is based on “Why Enterprise Integration Patterns?” paragraph in the book Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf) [1]:


  1. Patterns are accepted solutions to recurring problems, for example,

    • How can I add information from the third party before sending the message to a receiver system? The answer is simple – use the ‘Content Enricher’ pattern.

    • I need to send orders to two systems – A and B. However, system A only requires the order if the order costs over £500. How can I achieve this? The answer is simple – use the ‘Message Router’ pattern.

  2. Patterns are abstract, i.e., you can apply patterns in SAP Cloud Platform Integration as well as SAP Process Integration and many other integration tools available in the market

  3. Patterns provide a vocabulary to efficiently describe the solution like used above in point number 1.


I hope you are excited to know more about individual patterns and see how to implement them in CPI.


EIPinCPI Rating

EIPinCPI rating indicates how well a given pattern is supported in CPI (Credits: Owen Pettiford and Daniel Graversen). From the Selective Consumer pattern, EIPinCPI rating is added.


Hope this helps,
