Computing in the Cloud

By Holly Gilbert

With CloudSigma 2.0, customers can have private patching directly into their virtual networks in the cloud. Jenkins notes that most public-cloud-computing providers have companies run a virtual private network (VPN) server over a public IP address. But many customers want to connect to the cloud platform without public-IP-address exposure for performance and security reasons.

“In our system we have things [that are] like virtual wires…really like virtual Ethernet cables between the virtual machine, just like you would have with switches and hardware,” he says. “Instead of running a physical line to our cloud, we put that onto a port in our cloud, we map that physical port switch into one or more virtual networks within the cloud for the customer, so they can then not have any public IP on any of their virtual machines.”

The DRaaS feature of CloudSigma 2.0 is also noteworthy because it allows client companies to maintain a virtual mirror image of their entire corporate network environment on the cloud infrastructure. “If there’s a disaster, [customers] can bring up that environment in the public cloud immediately, and they can do so without running two environments all the time,” says Jenkins, “because they’re able to easily recreate the same environment within CloudSigma that they can create in their own environment.”

Jenkins says the solution allows customers to maintain full control of their security settings, unlike most public-cloud offerings. “They’re able to secure their servers, patch their servers however they want, so they’re able to take a much better approach in terms of securing their computing,” he notes.
