Multitenancy in the Hypervisor

For enterprises to start running VMs on third party hardware in the cloud, we have to get to a point where Coke and Pepsi could comfortably run applications on the same physical machine without a) worrying about secure isolation and b) ever learning that they had brushed virtual shoulders.

For enterprises to start running VMs on third party hardware in the cloud, we have to get to a point where Coke and Pepsi could comfortably run applications on the same physical machine without a) worrying about secure isolation and b) ever learning that they had brushed virtual shoulders.

Generally, hypervisors today are very good at isolating a user’s CPU and Memory resources, but they rely on third party technology to isolate networking and storage.

For instance, many of today's "Enterprise" cloud infrastructure providers are using a combination of VMware and Cisco vLan functionality to give each user a private network, coupled with an EMC SAN volume for storage isolation.

This is an adequate solution, but it is expensive and complex. In the last week, I’ve talked with two service providers about this, and they both saw this problem as one of the hurdles they need to overcome if they are going to push their existing dedicated server hosting business to virtual machines.

We’ve been working on virtualizing networking and storage from within the hypervisor for the last year, and we’ve recently been demonstrating our beta cloud to interested companies. The technology we’ve built gives each user a dedicated virtual router and a dedicated storage volume when they create an account. All of this is orchestrated within the hypervisor, using just raw datacenter bandwidth and local RAID-based storage servers.

By doing this, we’re enabling clouds built on commodity hardware to offer the same privacy and isolation that Cisco, EMC and VMware are providing to their fortune 100 customers.

Open@Citrix

Citrix supports the open source community via developer support and evangeslism. We have a number of developers and evangelists that participate actively in the open source community in Apache Cloudstack, OpenDaylight, Xen Project and XenServer. We also conduct educational activities via the Build A Cloud events held all over the world.
