Over the last couple of years, IBM, despite having a rich internal technology ecosystem and a number of competitive blade and CI offerings, has not had a comprehensive integrated offering to challenge HP’s CloudSystem Matrix and Cisco’s UCS. This past week IBM effectively silenced its critics and jumped to the head of the CI queue with the announcement of two products, PureFlex and PureApplication, the results of a massive multi-year engineering investment in blade hardware, systems management, networking, and storage integration. Based on a new modular blade architecture and new management architecture, the two products are really more of a continuum of a product defined by the level of software rather than two separate technology offerings.
PureFlex is the base product, consisting of the new hardware (which despite having the same number of blades as the existing HS blade products, is in fact a totally new piece of hardware), which integrates both BNT-based networking as well as a new object-based management architecture which can manage up to four chassis and provide a powerful setoff optimization, installation, and self-diagnostic functions for the hardware and software stack up to and including the OS images and VMs. In addition IBM appears to have integrated the complete suite of Open Fabric Manager and Virtual Fabric for remapping MAC/WWN UIDs and managing VM networking connections, and storage integration via the embedded V7000 storage unit, which serves as both a storage pool and an aggregation point for virtualizing external storage. The laundry list of features and functions is too long to itemize here, but PureFlex, especially with its hypervisor-neutrality and IBM’s Cloud FastStart option, is a complete platform for an enterprise private cloud or a horizontal VM compute farm, however you choose to label a shared VM utility.
Today's move by Citrix to put its CloudStack IaaS solution into the Apache Foundation says more about the state of the cloud market than it does about OpenStack. As our Fall 2011 Forrsights Hardware Survey shows, about 36% of enterprise IT leaders are prioritizing and planning to invest in IaaS this year. That means they need solutions today and thus service providers and cloud software vendors need answers they can take to market now. OpenStack, while progressing well, simply isn't at this point yet.
Second, Citrix needed to clarify the position of its current open source–based solution. Ever since Citrix joined OpenStack, its core technology has been in somewhat of a limbo state. The code in cloudstack.org overlaps with a lot of the OpenStack code base, and Citrix's official stance had been that when OpenStack was ready, it would incorporate it. This made it hard for a service provider or enterprise to bet on CloudStack today, under fear that they would have to migrate to OpenStack over time. That might still happen, as Citrix has kept the pledge to incorporate OpenStack software if and when the time is right but they are clearly betting their fortunes on cloudstack.org's success.
There are myriad other benefits that come from this move. Two of the biggest are:
