One element of the technology, OpenCloud Bridge, is a secure tunnelling technology which allows data and workloads to be transferred between internal corporate networks and external third-party cloud platforms.
Through OpenCloud Bridge, external cloud environments — such as Amazon’s EC2 or Rackspace’s Cloud Server – appear to be an extension of an organisation’s internal network. The technology will work on any virtual hypervisor but requires both sides of the data transfer to be using Citrix’s NetScaler server technology, meaning that currently not all cloud services are currently able to use OpenCloud Bridge.
Users of OpenCloud Bridge will also be able to move virtual machines and workloads between VMWare and Citrix virtual machines using the OpenCloud Bridge technology.
However, moving data between software-as-a-service applications — from Microsoft Dynamics CRM to Salesforce.com, for example – isn’t currently on Citrix’s agenda, as application-to-application data transfer requires significant changes to the way the data is packaged and structured, something that will need cross-vendor support before it can be implemented.
…VMWare, which allows movement of applications on virtual machines between off-premise and on-premise environments through its vFabric technology but only if they remain within the VMWare stack.
“My view is Citrix have hung their hat on the open source banner, an open stack [which] they’re hoping the service providers take up to enable customers to be able to enter and exit cheaply and quickly whereas VMWare are hoping in their tie-ups with people like Salesforce.com that their platform, based on a proprietary vCloud API, will be adopted by people so they can link service providers into their stack,” Ovum senior analyst Roy Illsley told silicon.com.
OpenCloud Access works in conjunction with the Citrix Receiver technology, a client-based system to allow users to access internal and external cloud applications in an application store-style interface.
