This is about as close as you can get to an Amazon private cloud using OpenStack

OpenStack company CloudScaling wants to make private clouds that look like Amazon’s public cloud

Cloudscaling’s co-founder and now CEO Randy Bias (pictured) feels strongly that it’s important for enterprise private clouds to be architected and act similarly to Amazon Web Services’ public cloud. So, Cloudscaling uses OpenStack’s cloud platform and puts AWS-like features on top of it. The third version of Cloudscaling’s Open Cloud System (OCS), numbered 2.5, was released this week.

OCS 2.5 comes with a number of advancements, most notably the introduction of virtual networking features into the product. Just like with Amazon’s Virtual Private Cloud, OCS 2.5 now comes with similar capabilities for users to setup, define and granularly control different networks. The biggest advantage to this, Bias says, is the ability that this will allow legacy applications to be migrated to this next-generation architecture.

He explains that many existing enterprise applications have various tiers of networks connected to them, for connecting to databases, or for security and firewall purposes. In many cloud deployments, there isn’t an ability to control network segmentation of those applications, instead networks and IP addresses are created willy-nilly and then removed when the virtual machine is turned off. Using VPC-like features, however, users can get network topology similar to that of their traditional enterprise applications, making migrations to the cloud easier, he says.

Along with the addition of VPC and SDN capabilities, OCS 2.5 also comes with advancements to its block storage feature, including the ability to boot block storage instances from persistent volumes, meaning they are storage caches that are not connect to a specific virtual machine. Version 2.5 also adds the ability to consolidate and aggregate block storage volumes for high performance workloads.

The bigger point is that Cloudscaling is an important company within the OpenStack ecosystem, and one that has taken an approach that fully embraces Amazon Web Services, and soon Google Compute Engine APIs and architecture. Bias, who also sits on the board of directors for the OpenStack Foundation, is one of the leading advocates for advancing compatibility between OpenStack and AWS. Others within the open source community don’t feel that is as necessary.

With a recent management shakeup at Cloudscaling, Bias has merged from being CTO to CEO of this company he co-founded, and now he’s putting his money where his mouth is and not just advocating for AWS compatibility, but providing it in his company’s product.
