Elastra today unveiled an updated cloud strategy that aims to tackle one of the biggest challenges of cloud computing: How to move applications smoothly between in-house infrastructure and clouds like Amazon’s EC2. If the strategy works, it could pave the way for so-called “hybrid clouds,” those that combine on-demand capacity with in-house compliance.

Elastra’s not the only one building a path to hybrid clouds. VMware this week announced a “private cloud” offering at VMWorld Europe that lets applications run both in-house and atop clouds, just as long as those cloud providers also use VMware. Others, like Enomaly, have been tackling the problem as well.

To build a hybrid cloud, you first need to bundle up all of the web servers, databases and configurations that make up the application — what Elastra calls a “deployment.” This deployment is portable, able to run in a cloud or in-house, because it defines not only the components but also how they interact and grow. Then you need to set rules as to where and how that deployment can run according to your specific security, capacity and business requirements. For example, a deployment that deals with credit cards might only be able to run on a PCI-compliant platform.

What’s been missing up until now is a way to fulfill the second part. With the launch of an open beta for the Elastra Enterprise Cloud Server 2.0, IT managers can set policies as to which applications can run where, such as:

  • Which capabilities, such as PCI compliance, a cloud must provide in order for a particular deployment to run.
  • How big or small the application can be.
  • How to marry a component (such as a JBoss server) to the available resources (such as a size of EC2 virtual machine.)
  • How to grow the deployment when certain events happen.

Stu Charlton, Elastra’s chief software architect, thinks early adopters of hybrid clouds will be enterprises migrating their applications into the cloud for development, testing, QA, and stress-testing, then bringing them back in-house for production.

In the end, infrastructure-agnostic application deployments like those built on Elastra, VMWares, and Enomaly help sever the umbilical cord that links legacy applications to their underlying infrastructure. With the addition of policy-based management, they become candidates for cloud deployments. Which is very good news for cloud providers.

  2. It is unclear how the “enterprise cloud” is provisioned. Moving images between corporate data centers and Amazon means they would support either VMWare, Xen or/and LVM images, as well as the AWS api, but I do not see any mention on their site.

    Rules based deployments and scaling isnt a big deal, there are already people doing that such as RightScale. The compliance based feature is nice but not a big deal for any of the other providers to add the feature to their settings.

    I am missing something here?

  3. Kaiyzen, I feel the same way. Also, save for QA / Testing / Performance benchmarking, I just don’t see a strong case for these hybrid clouds especially if it involves the transportation of sensitive customer data.

    More of a strong business case is supporting internal clouds, wherein cloud infrastructure is used to make data available to more groups within an organization, without having to resort to expensive development and integration efforts. Some of the work being done by the Cloud Interoperability Forum seems to make some headway or at least raising the larger issues.
