Comment: Due to the variation in actual cloud requirements, different deployment model (private, public, hybrid) and use cases (IaaS, PaaS etc.) the matrix will only list the available products and capabilities. It will not list evaluations (green, amber, red) rather than providing the information that will help you to evaluate it for YOUR environment.

Overview:
IaaS (private and hybrid)
In July 2013 Red Hat announced Red Hat Cloud Infrastructure (RHCI) -a single-subscription offering that bundles and integrates the following products:
- RHV - Datacenter virtualization hypervisor and management for traditional (ENTERPRISE) workloads
- Cloud-enabled Workloads: RHEL OpenStack - scalable, fault-tolerant platform for developing a managed private or public cloud for CLOUD-ENABLED workloads
- Red Hat CloudForms - Cloud MANAGEMENT and ORCHESTRATION across multiple hypervisors and public cloud providers

PaaS:
Red Hat also offers OpenShift (PaaS), as on-promise technology as well as available as online (public cloud) offering by Red Hat. Details here - http://red.ht/1LRn7ol

There are a number of public and hybrid (on-premise or cloud) offerings that Red Hat positions as complementary like Red Hat Storage Server (scale-out storage servers both on-premise and in the Amazon Web Services public cloud). Details are here: http://red.ht/1ug7XTY
