PlanetLab is a global research network supporting network services development since 2003. It has over 1000 researchers using its 530 nodes across 717 sites to develop technologies like distributed storage, networking mapping, peer-to-peer systems, and distributed query processing. Cloud computing provides resources through services rather than direct access, while grid computing involves aggregating distributed resources for tasks like number crunching. The objective is to understand how PlanetLab can maintain benefits while preparing for the future, and to compare grid and cloud computing models in terms of assembly, offered services, and differences in scale. The conclusion is that cloud computing will become the main information technology as it realizes the vision of grid computing through standardization and dynamic pricing models.
