Table 3. Comparison of the discussed approaches to distributed computing models and the traditional CCP4 desktop setup in crystallography.

Criteria Web services CCP4 Cloud CCP4 web application Traditional desktop setup
Functionality Limited to automatic structure-solution pipelines Full Subject to the level of development; currently lacks a number of tasks and interactive graphical tools (Coot) Full
Interface complexity Easy to use Usual Usual Usual
User projects support No Yes Yes Yes
Bandwidth requirements Low High Medium to low N/A
Suitability for standalone use on desktops Not suitable Can execute jobs on remote servers from ordinary CCP4 setups Allows desktop setups in flexible configurations Fully suitable
Suitability for use on mobile devices Yes Not very suitable owing to the specific graphical design and extensive use of mouse Yes No
Hardware requirements Low beyond number-crunching facilities High in addition to number-crunching facilities Low beyond number-crunching facilities Medium for most tasks; high for automatic structure solvers
Additional software requirements None High Low N/A
Portability (suitability for corporate deployment) May require a custom installation Requires IT support with cloud setup experience High N/A
Maintenance burden Low Dependent on local IT support Low Low to medium
