[joehuang] suppose that there are two OpenStack instances in the cloud, and vendor A developed an orchestration layer called CMPa (cloud management platform a), vendor B's orchestration layer CMPb. CMPa will define boot VM interface as CreateVM( Num, NameList, VMTemplate), CMPb may like to define boot VM interface as bootVM( Name, projectID, flavorID, volumeSize, location, networkID). After the customer asked more and more function to the cloud, the API set of CMPa will be quite different from that of CMPb, and different from OpenStack API. Now, all apps which consume OpenStack API like Heat, will not be able to run above the prosperity software CMPa/CMPb. All OpenStack API APPs ecosystem will be lost in the customer's cloud.

[joehuang] For example, Huawei's IMS can only run over Huawei's ATCA hardware, even you bought Nokia ATCA, the IMS from Huawei will not be able to work over Nokia ATCA. The telco APP is sold with hardware together. (More comments on ETSI: ETSI is also the standard organization for GSM, 3G, 4G.)
 
Thanks,
