SAP has already demonstrated All-in-One running in the cloud so there is clear precedent for an OLTP system operating in this manner. When we met with Dr. Plattner, I reminded him that a year or so ago he said that he wasn't sure (at best) whether the Business Suite could be moved to the cloud. Today he is certain but with the caveat that the timing is unclear and benefits today might be elusive. "The Business Suite was not written for massive parallelization but with HANA it may be possible to shrink the suite. - possibly up to 90%." Even then there has to be a re-write: "I don't want 20 years of ABAP carried forward into new technology. It's just not feasible to...deliver breakthrough performance and cost savings," said Dr. Plattner. In that one statement, Dr Plattner is reiterating what he has said in different ways over the last few years - do not customize at the core ERP level.
