Challenges to Hybrid Cloud Deployment with OpenStack in Enterprises

By Larry Jiang, CEO of KeyTone Cloud

Hybrid-cloud deployment is gaining more and more attention/momentum in the Enterprise and Telco SP markets in China. The most important reasons for Chinese enterprises to adopt hybrid cloud deployment include:  hybrid cloud deployment gives enterprises security and control they want to keep sensitive data and apps (This is especially so in Asian countries), at the same time they have the options of running applications in public clouds so as to utilize the elasticity and flexibility of public clouds when needed. 

Deployment of hybrid clouds based on OpenStack to enterprises in China, however, faces many challenges at many fronts. The following are the major issues that KeyTone Cloud, a hybrid-cloud technology enabler and cloud service provider, encounters with enterprise “hybrid cloud deployment”. The quotes for “hybrid cloud deployment” reflect the following complex scenarios and requirements of hybrid cloud deployment, as interpreted by Chinese enterprises (their definitions of hybrid-cloud):

Scenario #1: Utilizing inter-connected private cloud and public cloud. This is the traditional definition of hybrid cloud. Enterprises adopt public clouds for agility, elasticity, and capacity; and they adopt private cloud for security, control, and special enterprise workloads. The challenges for OpenStack here are the cloud inter-connection functionalities, cross-platform VM migration capability, and bursting of applications from one cloud to another type of cloud platform. We resolved theses issues to certain extent with implementing L3 GRE Tunneling, enhanced IPSec VPN service, and supporting BYOI (Bring Your Own Image) in a OpenStack-based cloud platform. Cloud-bursting of applications from one cloud to another can be achieved with OpenStack application orchestration module HEAT and KeyTone developed BYOI functionality.

Scenario #2:  Hosting of Physical Servers (Bare Metal) and Virtual Machines on the same virtual network in OpenStack. Some customers refer this as “hybrid cloud” too in China. No matter what we call this kind of cloud deployment, often times some Enterprise Applications could not run on VMs on OpenStack due to various reasons and the Apps have to be run on physical servers. The physical servers need to be on the same virtual network of VMs to make the whole application system functional. We enhanced OpenStack so that not only we can manage and provision baremetal but also we are able to add physical servers to the virtual networks the VMs are on, thus allow the physical servers to utilize the L4-L7network services such as connecting to Virtual Router, ELB, Floating IP, etc. the same way as the VMs. 

Scenario #3:  Managing OpenStack VMs, IBM Power VMs, vCenter provisioned VMs on the same virtual network on a OpenStack platform. With the capability we achieved in Scenario  #2, allowing Power VMs and VMs provisioned in vCenter to be part of the resource pools in OpenStack and to utilize the network services provided by Neutron become a reality. The capability of managing VMs provisioned in multiple clouds in a single pane of glass in OpenStack is what enterprise customers want to protect their existing investment in other clouds solutions (such as VMware, PowerVC, & Azure). 

To summarize, KeyTone Cloud enhanced and implemented many new IaaS and SDN functionalities on top of OpenStack to meet various challenges with deploying OpenStack based Hybrid Clouds to enterprises. The elastic cloud services that KeyTone has implemented on top of OpenStack include, but not limited to, the following:

·         Auto Scaling of VMs in an ELB group

·         Live Vertical Scale-up of VM instance without rebooting it

·         Site-to-Site L3 GRE tunneling

·         Host-to-Site VPN service over PPTP and OpenVPN

·         Supporting BYOI - Bring Your Own Image

 

·         Hosting of Physical servers and VMs in the same network on OpenStack
