Bound to happen as no one used SAP's internal cloud. I bet the Google relationship will be the first amongst equals, whereas Azure will be the last amongst equals... Mainly because Google Apps can combat Microsoft for SAP... and MSFT is clearly driving Dynamics into the 365 suites to knock down SAP. SAP would benefit if everyone moved to G Suite. Also Google has that worldwide private fiber network which helps with HANA's story... no point in having a low latency database if users are accessing it from all over on the slow public internet.
