I previously wrote a review of the Microsoft Azure public cloud and included a comparison between Azure and AWS (Amazon Web Services) and will now compare OpenStack and VMware vCloud. For a review of IaaS (Infrastructure as a Service) see my blog post and video.
This table provides a simple and high level comparison of OpenStack and vCloud.
||Type 2 virtualization - Libvirt layered on top of Linux. Supports various hypervisors: XEN, KVM, HyperV...
||Type 1 virtualization - bare metal; vSphere hypervisor only.
||Open API, Command line, Web console, Orchestration tools. Distributed components: storage, networks, compute,,,
||Web console, API; (requires vCenter to centrally manage resource pools, hosts and storage.)
||Not traditional filesystem, Object or block storage, vertical or horizontal scale out, uses commodity hardware and compatible with NAS devices
||Traditional file system (eg NFS) or proprietary VMFS storage managed by vCenter
||Direct connected, non-routable, DHCP. Managed with command tools or web console.
||Direct connected, non-routable, DHCP. Requires VMware vCloud Networking and Security.
|System usage data is sent from Nova as usage events and published to the AMQP broker
||Requires VMware Chargeback Manager
||From images or snapshots, create instances of various sizes: micro, small, medium, large, xlarge.
||Existing VMware vApps/VMs must be imported into vCloud and then offered as a service.
|Public cloud compatibility
||Heat provides AWS CloudFormation compatibility;NOVA provides EC2 API compatibility
||vCloud Connector connects a private vCloud to the public VMware vCloud. Project cinderella offers some EC2 compatibility (does not seem to have much traction)
||Over 60 organizations support the OpenStack foundation.
||vCloud is a product owned and sold by a (large and successful) company.
