We tend to be dealt the computing environment in which we must operate.
Few of us have enough influence to steer the direction of central computing on our campus.
Thus, we try to match our computing needs with the resources provided locally.
Computing reality

Develop a computing strategy that identifies the hardware, the software, and the network connectivity
needed to support the level of data service you are providing now and will be in the near future.
Match to level of service

System administration takes a lot of time! think twice about becoming
your own system administrator
Implementation strategy

Purchase compatible computing equipment to receive maintenance
support simplifies the sharing of
peripheral devices

Align with local institutional repository services and digital preservation initiatives
introduce data to the planning of your institutional repository

Data infrastructure models Data centres
• The data centre is part of the instrumentation infrastructure.
• e.g., the Large Hadron Collider Data repositories
• The repository is part of a specific institution’s larger stewardship mandate for digital resources.
• e.g., Odesi in Scholar’s Portal Domain archives
• Domain archives are institutions established explicitly to preserve and provide access to a domain’s data.
• e.g., the ICPSR and the UKDA
