VMware has launched its long-anticipated public IaaS (infrastructure as a service), touting its virtual networking capabilities as a differentiator from other established hybrid cloud offerings.
VMware's vCloud Hybrid Service will be based on the company's vCloud architecture, allowing customers to shift their VMware encoded workloads between in-house and the VMware hosted service, a practice known as running a hybrid cloud.

"You can write an application and be safe in the knowledge it can be run anywhere," said VMware CEO Pat Gelsinger, in a Web conference announcing the new service, adding that much of the complexity enterprises experience in deploying their workloads in the cloud comes from preparing their in-house applications to run in a new environment.
Those applications that VMware has certified to work with the company's vSphere virtualization platform will also work without modification on the vCloud Hybrid Service, Gelsinger said. The company touts that its software is used by 500,000 customers.
VMware is not alone in offering a hybrid cloud approach. Both Hewlett-Packard and Microsoft both tout how their cloud services work smoothly with their on-premises software, allowing customers to move their workloads between in-house and hosted servers.
Gelsinger, however, touted VMware's expertise in virtual networking as the key that would make its service more appealing than the others. Last year the company purchased SDN (software-defined networking) pioneer Nicira, and has been incorporating Nicira's technology in its own stack of software.
The new service uses virtual networking technologies to extend customers' layer two and layer three networks from their data center to the vCloud Hybrid Service. "This is a real game changer for many of our clients, and completely reduces the risk of deploying applications onto this public cloud," Gelsinger said.
In VMware's approach, a customer's virtual networks are extended across a WAN (wide area network) to the vCloud Hybrid Service, using the Internet or a dedicated link. The company's infrastructure tools, such as load balancers and firewalls, could be packaged in VMware virtual machines, so they can be deployed to the cloud, or moved between the two.
By incorporating virtual networking technologies, VMware can minimize a lot of the work it would take to run applications. Customers already using a VMware platform don't have to worry about repackaging their applications in virtual containers, or changing networking connectivity information.
Extending the virtual networks would also allow organizations, with little additional work, to maintain compliance with internal policies, as well as with external regulations such as SOX (Sarbanes-Oxley Act), HIPAA (Health Insurance Portability and Accountability Act), or PCI (Payment Card Industry) standards, Gelsinger said.
