Google offers a new concept of “software-defined community cloud” • The Register


Google has given us all a whole new variety of clouds to consider: a “software-defined community cloud”.

The advertising giant’s reflection on this variety of cloud begins with the US National Institute of Standards and Technology’s definition of a vanilla community cloud as “an infrastructure … provisioned for exclusive use by a specific community of consumers of organizations that have common concerns (eg, mission, security requirements, policy, and compliance considerations) “.

Google believes that community clouds built according to this definition have “often … failed to meet specific goals or required significant compromises for users” because they rely on physical separation for security.

Senior Product Manager Christopher Johnson and Customer Engineer Jason Callaway say physical separation doesn’t really hurt security, but “often it doesn’t make significant advances in security, manageability or compliance. “. Community clouds may therefore have poor security within their castle walls.

The two Googlers believe that a software-defined community cloud can improve this situation by providing better governance, even on shared infrastructure. Lest the notion remain too nebulous, they set the following criteria:

  • Projects are in effect private clouds with isolated infrastructure primitives and their own enclaves;
  • Only personnel with specified qualities such as specific citizenship are allowed to access it;
  • The locality of the data is imposed by software.

Another element that Johnson and Callaway suggest is unique to a software-defined community cloud is the use of “insured workloads” – which happens to be a product of Google’s cloud service.

Google’s post suggests that the software-defined community cloud could be a new way to create government clouds.

Although Google invented the jargon in this article, it didn’t really invent a new concept. He is far from alone in suggesting that a well-managed, shared infrastructure can handle demanding and sensitive workloads. Most of the major clouds have obtained government security certifications and may indicate the deployment of impressive isolation technologies and careful access control. The likes of VMware and OpenStack will also raise their hands to run software-defined clouds for any community.

Google’s post forgets to mention that its cloud lacks dedicated regions for governments and that its competitors AWS, Oracle, IBM and Microsoft Azure all have such facilities in the United States.

Perhaps the new Google jargon will be of interest to public sector customers beyond the United States. Corn The register I can’t imagine Google’s cloudy rivals will squirm at the prospect of being beaten by a glamorous name for something that already exists. ®
