The second portion is a larger portion of the memory device than the first portion.

Abstract: A secure boot monitoring and validation process for operating system (OS) initial installation or upgrade operations. A validated copy of OS boot files is made during OS installation. The boot files are stored in a first RAID array. A checksum comparator or OS boot file filesystem check (FSCK) component validates the boot files upon initial installation of the OS by comparison with a secure copy of the boot files, which are stored in a second RAID array. Any validation failure indicates corruption or unwanted modification of the boot file data, and an autorecovery operation using different boot partitions is attempted.

Abstract: A powered device electrical data modeling and intelligence system is used to monitor electrical data of powered devices to determine in-use activity thereof. A number of network-enabled electric plugs are deployed in a region, for example, within certain areas of a floor of a building or within certain floors of a building. Each of the network-enabled electric plugs is configured to deliver electricity from an electricity source to one or more powered devices located in the region. A server runs a web application used to monitor electrical data for the region based on electricity drawn by each of the one or more powered devices. The web application computes usage metrics for the powered devices by modeling electrical data for the powered devices into clusters representative of device operational states. The web application may then determine an operational state of a powered device according to the usage metrics.

Abstract: Bootstrapping a microservices container registry. A computing system node receives an installation package. The receiving computing system node bootstraps an initial invocation of the microservice by first installing a local container registry from the installation package and then by installing the microservice from the installation package. The installation package contains additional components that can be extracted, installed and invoked by executing the microservice at the computing system node after extracting from the local container registry. The installation package is generated by any node of the computing system and contains code corresponding to infrastructure microservices that are installed before invoking microservices that depend on the infrastructure. Temporary domain name services are installed from the installation package at a node-local IP address. The temporary domain name services are switched over to a different domain name service at a different IP address.
