UPGRADE OF NETWORK OBJECTS USING SECURITY ISLANDS

摘要

Systems and techniques to upgrade network objects using security islands are described herein. Security islands of node groupings are created based on trust relationships between nodes in an edge network. An upgrade request may be received to upgrade a target edge node in the edge network. Building blocks may be identified for a package installed on the target edge node to be upgraded. A state backup may be stored for the building blocks. An upgrade command and an upgrade payload may be transmitted to the target edge node. The target edge node may be queried to obtain a status of the target edge node. An upgrade action may be determined based on the status and the upgrade action may be executed.
