XPUS13: Network Multitenancy in Xen-Based Clouds

Category : Xen Presentations
Views : 360
In Infrastructure-as-a-Service (IAAS) clouds, Xen is a popular choice of hypervisor. While the Xen hypervisor has strong isolation, integrating with the cloud infrastructure environment (switches, routers, load balancers, firewalls, ip address allocation) requires additional work by the IAAS cloud management platform (CMP) to achieve this. We will look at various solutions such as network virtualization, SDN, network function virtualization and L3 isolation that work with the Xen hypervisor, in the context of the Apache CloudStack IAAS platform. Attendees will come away with an understanding of the challenges of network isolation, how Apache CloudStack solves some of the scaling issues and the future of Xen-based clouds.
