1. A computer-implemented method, the method comprising: transmitting, by a computing device of a cloud computing system, a first request to a smart network interface card, the first request requesting a pre-boot execution environment executable, the smart network interface card being associated with a metadata management service that manages secure boot metadata operable for verifying a boot loader; receiving, by the computing device and from the smart network interface card, the pre-boot execution environment executable; verifying, by the computing device, the pre-boot execution environment executable; and executing, by computing device, the pre-boot execution environment executable in response to verifying the pre-boot execution environment executable, the executing of the pre-boot execution environment executable comprising: transmitting a second request to the smart network interface card, the second request requesting the secure boot metadata, the pre-boot execution environment executable being configured to request the secure boot metadata from the smart network interface card; receiving, from the smart network interface card, the secure boot metadata; mounting a boot partition; loading the boot loader, the boot loader being obtained from the boot partition; verifying the boot loader based at least in part on the secure boot metadata; and executing the boot loader in response to verifying the boot loader; wherein the pre-boot execution environment executable is a program file that is capable of running on the computing device.
