Data Challenges Acquisition of data
Many different data sources Different regulations/mechanisms for accessing data Lack of automation Finding the right data
Managing data Scattered and unorganized data Inadequate tools for recording/maintaining metadata
Data without metadata is meaningless Lack of suitable metadata standards Validation of metadata
Tracking provenance of data Pre-processing of data
Raw data typically cannot be directly analyzed Significant amount of time spent preparing data for analysis Lack of automation

Application Challenges Access to software available in research lab while in
field or other locations Installing, configuring and updating software System dependencies of software Awareness and suitability of available software Sharing applications Getting help in using applications Sharing results and getting feedback Co-location of data and applications

Cloud Computing Infrastructure
Developed by the GRC (in collaboration with HP Labs)
Enables dynamic allocation and management of virtual machines and cloud services
Running on HP Labs Data Centre at the UofC
Similar to Eucalyptus, Nimbus and OpenNebula but has greater focus on scheduling capabilities and efficient image management
Automated Service Provisioning ENvironment (ASPEN)
