5. Copy the certificate, including the lines  -----BEGIN CERTIFICATE-----  and  ----END  CERTIFICATE-----  and paste it to both files:  truststore-Cert-mykey.crt  and  keystore-mykey.crt 6. Run  generateSecret.sh. ./generateSecrets.sh my-kafka-secret icp4i Deploy the BAR file 7.9 Splitting an integration across on-premises and cloud 7.9.1 Overview Perform the following to deploy the BAR files: This section discusses available features in IBM App Connect that enables hybrid Integration  between Cloud and on-premises deployments. When you are building your hybrid or multicloud infrastructure, you must make an important  architectural decision about splitting your integrations between these environments. IBM App  Connect makes this possible with callable flows. A message flow can call another flow  directly, both deployed on different platforms or environments, or indeed between  on-premises and cloud. A message flow can complete many different actions, if those actions are  computation-intensive, you can split them from the main flow and complete them somewhere  else. Callable flows also facilitate reuse because they can be called by multiple message  flows. You can split your flows between different applications in the same integration server,  or between different integrations servers, which can also be in different integration nodes.  Callable flows must be in applications. You cannot deploy in libraries or integration projects.  In a hybrid integration scenario, some parts of a message flow might logically belong in a  specific location. For example, if your flow queries an on-premises database, performance is  better if that part of the flow remains on-premises. But if part of your flow queries a website  multiple times, performance might be improved by running that part of the flow in the cloud.  534  Accelerating Modernization with Agile Integration Figure 7-103 Helm chart - Kafka Secret  6. On successful deploy of helm release, verify the connectivity with Kafka broker by  processing the message through IBM App Connect integration flow. 1. On the IBM App Connect dashboard, navigate to the Servers tab and click  Add server . 3. Copy the Content URL to the clipboard and click  Configure release .  2. Select BAR file and click  Continue . 4. Helm chart opens.  Click Configure .  5. Along with all usual configurations, ensure that you enter the secret name as defined  previously in the step for generating secrets for accessing Event Streams. In our case,  secret name is  my-kafka-secret  as shown in Figure 7-103.
