Private cloud management offerings are today very well suited to create and manage self-service scenarios for workloads that are either transient, or that require significant scaling of resources during the daily or weekly cycle of business activity. Private cloud management offerings are today not well suited to be the management solution through which all future workloads get provisioned an managed – but must become so, so as to participate in the further progress of virtualization. The best way for private cloud solutions to leverage the further progress of virtualization, is to help drive it- by helping to drive the concept of automated service assurance for business critical applications.
Choosing a Private Cloud platform involves trading off the scale of the environment, the types of applications running on the environment and compatibility with public cloud platforms with each other. VMware, DynamicOps, Gale Technologies, Abiquo, Platform Computing and Cisco offer the most compelling enterprise focused production application platforms. However other use cases and markets are best handled by other vendors.
So you are a loyal VMware customer. You have licenses for vSphere 4 and you are about 40% virtualized. Based upon the revised vRAM entitlements in the revised vSphere 5 licensing, you think you are going to be OK as you progress through the more demanding business critical purchased and custom developed applications that lie in front of you. But you would like a hedge and a simple way to manage the second hypervisor that is a part of that hedge. Help has arrived.
The question of whether and how to replace DRS is really a part of the question of what is in the virtualization platform and what is not. Clearly the virtualization platform consists of much more than the hypervisor. VMware would like to define the virtualization platform as all of vSphere Enterprise Plus, and then suggest that vCloud Director and its own performance management solutions are logical extensions of that platform. Enterprises need to be careful about where they draw their own lines in this regard. As VMware is a clear market leader both in terms of product functionality and enterprise installations, VMware needs to be given full credit for the quality of vSphere and its success. However full credit does not need to imply that one is 100% locked in to VMware solution as there is room to pursue third party IT as a Service, Performance Management, and Service Assurance strategies as well as replace/augment components in vSphere.
VMware intends to in an 18 to 24 month period come out with a true management stack that addresses capacity management, infrastructure performance, applications performance (and service assurance), configuration management, lifecycle management, extended provisioning and wrap all of that into a service catalog that lets IT provide a menu of services that can then be automatically provisioning on a dynamic (or even a cloud based) virtual infrastructure.
Enterprises are urged to look at virtualization management as a separate purchasing decision from the decision to purchase and standardize upon a virtualization platform. Third party vendors are likely to be more in tune with the requirements of constituents other than virtualization administrators, and products from these third party vendors are more likely to provide robust support for multiple virtualization platforms.
