Experience
SAP Cloud Integrator on Public Cloud
Led a team in the deployment of SAP landscapes onto the Azure platform. The project involved designing scripts to automate SAP infrastructure deployment on the public cloud.
This was originally a very fragmented and independent process that I re-designed and turned into an organized architecture where each completion of a step triggered the start of the next one. This gave us far greater control of the process, made it less error-prone, and protected us from when the process would fail in the middle.
SAP CPI initially and now SAP BTP is used as a major SAP intelligent enterprise product to connect SAP and Non SAP systems on the cloud and on-premises using hubs like APIs and cloud connectors.
