The Grid Checkpointing Architecture (GCA) aims to define the novel, Grid-e mbedded components and associated design patterns that will allow the Grids to utilize a variety of the existing and f uture low-level checkpointing mechanisms in a conscious way. The GCA introduces logical specialized components and their place within the Grid environment. The relations between the devised components and those pre-existing ones are defined as well. The emphasis has been put to make the GCA able to be integrated with other components and especially with the upper layer management services like for instance the Grid Broker or Workflo w Analyzer. The current shape of the GCA differs from the previous one and seems to be more flexible and more ad apted to WSRF-based Grid Services. Additionally, the current GCA proposal is extended with the support for emerging Virtual Machine Monitor technology that allows for suspending and later resuming the whole computing environment (together with the OS). The paper focuses on the general presentation of the proposed architecture and its individual components and on the essential usage scenarios.
