Overview
OVSvApp Solution for ESX based deployments
When a cloud operator wants to use OpenStack with vSphere using open source elements, he/she can only do so by relying on nova-network. Currently, there is no viable open source reference implementation for supporting ESX deployments that would help the cloud operator to leverage some of the advanced networking capabilities that Neutron provides. Here, we talk about providing cloud operators with a Neutron supported solution for vSphere deployments in the form of a service VM called OVSvApp VM which steers the ESX tenant VMs' traffic through it. The value-add with this solution is faster deployment of solutions on ESX environments together with minimum effort required for adding new OpenStack features like DVR, LBaaS, VPNaaS etc. To address the above challenge, the OVSvApp solution allows the customers to host VMs on ESX hypervisors together with the flexibility of creating port groups dynamically on Distributed Virtual Switch/Virtual Standard Switch, and then steer its traffic through the OVSvApp VM which provides VLAN & VXLAN underlying infrastructure for tenant VMs communication and Security Group features based on OpenStack. OVSvApp Benefits:
- Allows vendors to migrate their invested ESX workloads to cloud.
- Allows vendors to deploy ESX-based Clouds with native OpenStack, with less (or) no learning curve.
- Allows vendors to leverage some of the advanced networking capabilities that Neutron provides.
- Not required to rely on nova-network (which is deprecated).
- Does not require special licenses from any vendors to deploy, run and manage.
