  • Publication number: 20240078050
    Abstract: Container data sharing is provided. A second container of a cluster of containers is started to process a service request in response to detecting a failure of a first container processing the service request. The service request and data generated by the first container that failed stored on a physical external memory device is accessed. The service request and the data generated by the first container that failed is loaded on the second container from the physical external memory device via a dedicated hardware link for high-speed container failure recovery.

  • Patent number: 10961415
    Abstract: Laminates of polymeric films and solvent-based polyurethane adhesive formulations for preparing them are provided. The adhesive formulations include a hydroxyl-terminated polyester that forms crystalline polyester domains after reaction with an appropriate polyisocyanate, but prior to completion of cure. The result is an adhesive layer that substantially enhances the oxygen barrier properties of the adhesive and, therefore, of the laminate as a whole, while offering desirable convenience of application even at relatively low temperatures. The laminates may also exhibit desirable retention of barrier properties following flex-cracking.
