OLOS offers durable and cost-effective long-term preservation in Switzerland.
OLOS proposes a complete deployment flexibility: you can choose to use the OLOS web portal or to deploy OLOS with many different forms and configurations, in a cloud of your choice, on-premise on your own infrastructure, or a mix of both.
OLOS is a cloud-native application based on Docker and Kubernetes, operating on a group of two or more host machines (nodes) that have their own technology, copy of the datasets and backups. The number of nodes and their geographical distribution can be specified. Multiple copies replicated across multiple locations mitigate the risk of data corruption and loss.
As an API-based solution, OLOS has many advantages. Thanks to its modular infrastructure, OLOS enables institutions to streamline critical data processes, enforce policies and monitor performance, with a significant spare on development and maintenance costs.
We are aware that not only must data be easily accessible, it must also be thoroughly secured.
Preservation metadata (PREMIS) create a data-centric trust chain for submission to the repository, for archival storage and for dissemination from the repository.
Checksums are used to ensure the file’s integrity is being maintained in archival storage on a regular schedule.
Preservation planning tasks are monitored with administrative dashboards and notification systems, and audit trails offer a back-end view of system use.
