1. Infrastructure in 2009 and beyond ‘looking in, looking around, looking out’
VL-e workshop
David Groep, Nikhef
for P4: the Scaling Programme

2. Looking inwards: Scaling up?
More communities
More countries
Longer distances
More data
More information
Power
Cooling
Floor space
Asset life cycle management
More services
More heterogeneity
… and ever more people to run it?

3. Looking around: Monitoring and Stability
‘Availability is the product of its components’
Software hardening
stable set of core services
software engineering to push research ideas to production
Correlating events and logs
within a single site
across multiple sites
with the ‘users’ perception’
Inherent stability
ratio of petaflops and terabytes per site administrator is shifting – and the administrator is loosing!
how to get to a zero-conf, self-healing system
Incident management and support
more services means more failure modes
resolving more incidents without needing more experts or expertise

4. Looking out: Accessibility!
More than just CPU, Disk, and DBs
need to link with platform for collaboration
federated technologies for integrated services
Enabling technologies to make collaboration effective?
Rethinking common abstractions
scaling data management via a file system view has broken down – but now what?
new abstraction must be workable, hide enough, be logical, & degrade ‘gracefully’
Easier secure security
integrated login through federations
portals: simple access for simple tasks
