PS--yasha's initial message asked for a ReST API --that is most likely to be provided by OpenSTack and/or OpenNebula, the third of the three layers, and both of those are emulations of the one provided by Amazon AWS.
Also there is Deltacloud out there which is a set of libraries meant to deal with various clouds. I have never tried it personally. The EGI Federated Cloud project has put a lot of work into developing a higher-level implementation of OCCI (Open Cloud Computing Initiative) which can work with OpenStack, OpenNebula, and StratusLab.

One is the hypervisor itself, Xen, KVM, or VMWare or (gasp) Hyper-V from Microsoft. I know that libvirt as shipped with SL works with Xen and KVM, think it works with VMWare too but have never tried it. The second is the virtualization management layer--RHEV as bought from red hat or "ovirt" in the Open Source project. As far as I know neither RHEV or ovirt is part of SL. But the extra features that are in those libvirt versions and qemu-kvm versions are gradually getting back ported into the libvirt distributed by the enterprise, or you can go out and find the libvirt source independently. The third are actual cloud softwares such as OpenStack, OpenNebula. RedHat has an "enterprise" version of OpenStack, and another more "Development" environment of it designed to be deployed on top of CentOS. CentOS has long had an OpenNebula packaging and also a Xen on Centos6 setup. I am hoping both of these may be coming our way if and when the SL/Centos link happens but have no official word to that effect.

My understanding is that the EMC product is compatible with typical REST implimentations in that these evolved from various HTTP related services. Also, for reasons we could discuss off-list (or on list if you prefer), my personal preference is for Xen as a virtualisation suites. My understanding is that Xen does well integrate into a number of environments and distros.

The virtualization technology powering RHEV is kvm, which is fully compliant with libvirt (http://libvirt.org/). If you didn't want to use RHEV or Ovirt you could interact direclty with the libvirt API. The business logic that those products provide isn't there, of course, but you could build that out yourself if you were so inclined. It just takes time & talent. Is that what you're talking about wanting? -jduncan On Tue, May 27, 2014 at 12:52 PM, Yasha Karant <[email protected]<mailto:[email protected]>> wrote: Does SL (i.e., TUV EL) have a standard enterprise-quality production REST API that will interoperate with non-EL "clouds"? The most I could find on a short search is: http://developerblog.redhat.com/2013/12/12/advanced_integration_rhevm-part1/ Advanced integration with Red Hat Enterprise Virtualization Manager (RHEV-M) – Part 1 of 2 and https://fedorahosted.org/rhevm-api/ This is an effort to define an official REST API for Red Hat Enterprise Virtualization <http://www.redhat.com/virtualization/rhev/>. but that the fedorahosted project above is obsolete, replaced by: http://www.ovirt.org/Subprojects in which any mention of TUV by name is in the title of each reference.
