What is GeoGrid[edit]

One section mentions "GeoGrid" in conjunction with OpenStack. I couldn't find mention of it on the web.

Needs to be reorganized[edit]

It is unclear to me what the table headers mean.

  • "As a service": Does this mean that it requires no installation? They all do, except that some are offered by their sponsoring companies as paid services.
  • "Supported Hosts": What is the difference between running on Linux or Windows and running on Bare Metal?
  • "Supported Clients": It's all confused. For example, AppScale does not run Vmware, Xen, or KVM. AppScale runs under Vmware, Xen, or KVM.
  • "Features": the headers are defined ambiguously. For example, the way that AppScale supports S3 is different in nature than the way Eucalyptus supports S3.

I think part of the problem is that we are carelessly mixing both Platform as a Service software and Infrastructure as a Service software.

needs work[edit]

Comparing Platform as a Service software (e.g. openshift) and Infrastructure as a Service software (OVirt, Opennebula, etc) based on the same properties does not seem to be fair or useful. Probably the article should break down to comparisons in those categories or focus on one. --Kozka (talk) 19:44, 12 May 2013 (UTC)

+1 - mixing PaaS and IaaS here makes this messy and confusing. — Preceding unsigned comment added by Randybias (talkcontribs) 12:03, 12 July 2013 (UTC)

This article appears extremely biased toward public cloud providers and Open software[edit]

Cloud services and the providers listed are only those that provide public services. The tools and capabilities noted are a developers list of cloud features, not a cloud comparision. The services they offer (IaaS, PaaS, etc.) are a factor also. Arguably, Salesforce.com is a major SaaS player, and never mentioned as a community cloud provider of SaaS.

The definition of cloud remains arguable, but the NIST definition [1] illustrates a broader defnition consisting of

  • Public Cloud (which is partially covered in this article from a developer's point of view);
    • The current article omits vendors with major market share such as Savvis[2], HPcloud, and many others.
  • Community Cloud - A listing of those services with federated approach, perhaps like Microsoft Office 365.
  • Private Cloud - This is ignored completely, with many cloud products of major market share ignored:
    • VCE (consortium of VMware, Cisco and EMC),
    • HP CloudSystem,
    • IBM PureSystem,
    • Hitachi,
    • Fujitsu,
    • and many others.

Arguably, there are compontentized version of cloud systems by VMware, Cisco, Microsoft Opalis, and others that yield cloud results. The OpenStack initiative is yielding a build your own cloud stack, and the major players in cloud offerings are moving to support that as a standard. As Cloud comparison, these should not be a developer's view of the cloud, but a consumer's view primarily. Compare features such as infrastructure supported (Servers: IBM blades, IBM Aix, HP Blades, HP Proliant, Intelxxx, Sun xxx, Fujitsu xxx, etc.), Storage (EMC SAN, Hitachi SAN, HP 3Par, IBM SAN, NetApp NAS, etc), Network (Cisco, HP Procurve, etc), Management tools, Provisioning tools, support for virtualization (VMware, HyperV, KVM), etc. This is what I would expect in a comparison. The industry analysts like Forrester, Gardner, etc. look at market share, features, and various cloud capabilities as they compare the cloud providers, I would suggest the same. Look at this Porter Consulting paper is the reference paper for gauges for cloud comparisions for cloud: [3]
