Hana Enterprise Cloud (HEC) was SAP’s initial cloud offering. Each customer had their own S/4 Hana installation, which makes HEC a cloud-ready solution; meaning that technically, it could be installed in a cloud computing center. Hosting more than one company on one installation would make for cloud-native software. However, as many media outlets and analysts suggest, the public cloud is supposed to be the holy grail of cloud computing – but is it really, though?
Building software for the (SAP) cloud is very different from on-premises software. This obvious and trivial fact has consequences for software development rules.
