2 Agenda Overview & Premise Dilemma IT View (Boeing Perspective) Virtualization and Grids Infrastructure Ecosystem Advantage: Parallel Apps Limitations/Benefits Conclusion

3 Overview Ongoing progress in Grid technologies have enabled organizations to share and manage their resources beyond the earlier expectations of IT and user groups. The growth and evolution of Virtualization has enabled organizations to consolidate resources, especially in data center domains producing in some cases quite noticeable cost savings.

Premise As we continue to see improvements in processing, networking, information management and middleware, the relationships and roles of Grids and Virtualization

4 Premise As we continue to see improvements in processing, networking, information management and middleware, the relationships and roles of Grids and Virtualization become increasingly blurred. In this presentation, we will discuss possibilities of convergence between the two technological areas and suggest possibilities for the future.

5 Dilemma Grids and Virtualization share much in common, including: Continuing struggles with definitions. Largely a matter of perspective and audience Both seem to have noteworthy possibilities especially within an organizational or enterprise context Grid solutions may likely incorporate virtualization to address aspects of resource utilization Within Grids workload management can be virtualized Clearly they highly complement each other in addressing critical infrastructure needs of the enterprise (especially within a global context) However,. In spite of the similarities, its OK not to equate them

6 The IT View (Boeing Perspective) Must seamlessly connect our sites, suppliers and partners around the world. Share resources Unified management and monitoring Single source for reporting and accounting Dynamic information and data transactions (Time zone differences no excuse) Misconceptions... Restricted to a particular class of applications (R&D, Production, Operations, etc. ) Bandwidth and Resource unlimited All infrastructure investments are costly Grids dispel this one! Resource ownership This is mine and you can t touch it! Single, static monolithic solution is best Throw more hardware at it, that will solve it We must have Common processes and resources

7 Virtualization and Grids Increasingly being used with respect to multiple platforms Still some seamless interoperability issues to be resolved, but definite progress in the right direction Virtualization Open source and flexible adaptation (i.e., multiple platforms) emphasis is very welcomed by broad user communities. Increases resource utilization Enable strategic deployment of resources Can potentially save cost of porting applications across diverse platforms Hardware, storage, data, etc. Data and storage aspects and issues of increasing interest High level applications (e.g., ontology-based) can require more abstraction layers

8 Infrastructure Ecosystem Hardware Clusters/Mainframes/Processors/Storage Racked for departmental and 1u s for budget conscious Blades in datacenter for effective power management High availability and redundancy for critical mission applications and services Multi-core may increase performance / cost Middleware Provides load balancing for even workload distribution License server can enhance resource distribution and ensure regulatory compliance Grid middleware fosters user and site collaborations while accommodating nuances of diverse and broad application base Networking Latency and Real-time interactions directly related to BW capacity Critical in Network centric approaches

9 Advantage: Parallel Applications Grids and Virtualization can significantly improve performance by providing an advanced infrastructure that promotes parallel workload distribution Parallelizing apps can significantly increase performance for legacy applications with minimal code modification Virtual machines and interpreters provide built-in parallelism to high level applications or services A service-based or oriented approach is a natural progression in middleware development which takes advantage of a parallel, distributed approach Many advancements in development tools and MPI stacks have enhanced ease-of-use and performance

11 Conclusion Grids and Virtualization can provide significant inroads to building the viable global enterprise infrastructure necessary to accommodate diverse user needs and demands. Much of the reluctance and hesitance is associated with cultural misconceptions and hard line philosophies. The Grid and Virtualization communities, however, must bear a large part of the responsibility because there remains a lack of clarity in key technology areas and the rationale for using its solutions A more synergistic approach between the communities would well serve us and the broad user community in desperate need of solutions We must move beyond definitions and siloed approaches to the benefit of the diverse user community around the globe
