Hybrid clouds enable the flow of information between private and public cloud networks. Private clouds talk to public clouds, and vice versa, and the hybrid cloud is born.

On the heels of the OpenStack Summit in Portland, Oregon, and recent announcements from Microsoft, now is a good time to address the “state-of-the-state” of enterprise hybrid clouds. Due in large part to burgeoning industry alliances (e.g., OpenStack) and maturing cloud platform technologies (e.g., Microsoft Cloud OS), six technologies have emerged in the enterprise hybrid cloud market that deserve attention:

  1. OpenStack
  2. VMware vCloud
  3. CloudStack
  4. Eucalyptus
  5. Microsoft Cloud OS
  6. Google Cloud Platform

This diagram shows relationships between the leading cloud platforms and public cloud service providers:

Once a customer selects a cloud platform, a private cloud can be deployed behind the enterprise’s firewall or by a service provider via an offsite, hosted service then a public cloud service provider can be selected that supports that particular cloud platform. For example, if OpenStack is the cloud platform of choice, a customer can choose among public cloud service providers like AT&T, Dell, HP, or Rackspace.

5 observations and predictions

So what’s next for the hybrid cloud? After following this developing market with great interest, I’d like to offer several observations and predictions about the industry:

1) OpenStack is the mindshare leader in the open source / open standards hybrid cloud space. Here’s why:

    • Momentum - Contributors include major industry players like Ericsson, IBM, HP, Dell, Red Hat, Nebula, Cloudscaling, Piston Cloud, Ubuntu, AT&T, Nimbula (Oracle), SoftLayer, SUSE, Cisco, and VMware. As a result, there are many OpenStack solutions to choose from already
    • Wide Adoption – Rackspace, which distributes and is a founding member of OpenStack, has moved aggressively into hybrid cloud, with customers like HubSpot , and partners like Persistent Systems.
    • Growth – OpenStack has over 900 job postings
    • Vision – OpenStack has made interoperability, or “no vendor lock-in,” an essential feature.
    • Its recent announcement of a global cloud network is proof. Plus, Cloudscaling is offering an OpenStack cloud that can burst into Amazon or Google public clouds
    • Prediction - OpenNebula, the open source cloud platform founded in Europe, joins the OpenStack Foundation. OpenStack strengthens its European presence. See Cloud Watch for more information.

2) VMware strengthens its vCloud message and markets its own public cloud to expand its proprietary, hybrid cloud solution — leveraging thousands of ESX customers.

3) CloudStack grows and seeks more public cloud partners, in addition to Terremark.

    • Prediction – CloudStack establishes a closer, more strategic relationship with AWS to compete more effectively in hybrid clouds.

4) Eucalyptus merges with AWS.

    • Prediction – In support of its new $600 million, ten-year CIA contract, AWS purchases Eucalyptus to expand aggressively into enterprise hybrid cloud solutions.

5) Microsoft Cloud OS /Azure IaaS, founded on Windows Server and Windows Azure, is successful.

We’d like to hear from you. Will OpenStack maintain its impressive momentum? Do you believe that CloudStack will make an alliance with AWS? How will Google fare in the enterprise hybrid cloud space? What does this mean for your business? We look forward to your comments.
