Influence of Virtualization on Process of Grid Application Deployment DSRG Cracow Grid Workshop 2006 Background Virtualization is about creating illusions there are many CPUs on my one-CPU desktop, there is more memory in my system than physical RAM, a device is available here while in reality it is 100 km away, there is more than one machine in my box.

Influence of Virtualization on Process of Grid Application Deployment DSRG Cracow Grid Workshop 2006 Background Virtualization is the process of presenting computing resources in a way which gives benefit over the original configuration Virtualization describes the separation of a resource or request for a service from the underlying physical delivery of that service

Influence of Virtualization on Process of Grid Application Deployment DSRG Cracow Grid Workshop 2006 Key Features of Virtualization Consolidation –more resources perceived as one e.g. many hard disk drives creating one storage space Partitioning –huge resources dedicated for particular users e.g. one server machine divided on many virtual servers –isolation, security, etc. Containment –different resources perceived in the same way e.g. video cards from different vendors available with the same programming interface

Influence of Virtualization on Process of Grid Application Deployment DSRG Cracow Grid Workshop 2006 Techniques of Virtualization Machine Virtualization: –Hardware-level virtualization –Hosted virtualization –Hypervisor virtualization CPU –HyperThreading, TSS, FSS Storage virtualization: –NAS, SAN Memory –Virtual Memory Language –Virtual machines – Java VM,.NET CLR

Influence of Virtualization on Process of Grid Application Deployment DSRG Cracow Grid Workshop 2006 What is a NODE? Most obviously –a computer system But may be something smaller: –an OS on virtual machine –a Solaris project –a process – in case of CCM a ComponentServer –a thread And why not something larger: –a cluster
