Abstract: Techniques are disclosed relating to upgrading nodes. A computer system may detect that an updated node image has been created that is an update to a previous node image used to deploy a plurality of nodes into an environment associated with the computer system. The computer system may determine an upgrade order in which to upgrade a set of the plurality of nodes. The upgrade order may be determined based on a rank associated with a given node of the set of nodes by a ranking service. The computer system may then upgrade the set of nodes according to the upgrade order. The upgrading of a first node of the set of nodes may include deploying a second node based on the updated node image and then evicting a set of application pods from the first node and redeploying the set of application pods onto the second node.

Abstract: Techniques are disclosed relating to upgrading nodes. A computer system may detect that there is an update to a node image used to deploy a set of nodes managed by the computer system. The computer system may select, for an upgrade process, a first node from the set of nodes that includes a first volume used to store data of applications executing on that first node. The computer system may upgrade the first node by deploying a second node running the updated node image, transition the first node to a read-only mode in which read transactions but not write transactions are routed to the applications, and copy particular data from the first volume of the first node to a second volume of the second node. The computer system may, after completion of the copy operation, evict the applications from the first node and redeploy them on the second node.

Abstract: Methods, computer readable media, and devices for securely managing interactions between distributed components are provided. One method may include generating a first interaction identifier based on a first component identifier and data to be shared with a second component, storing the first interaction identifier in an interaction data store of the first component, sending a request to the second component including the first component identifier, the first interaction identifier, and the data to be shared with the second component, creating a graph node in an interaction relationship data store based on the first interaction identifier, receiving a response from the second component including a second component identifier, a second interaction identifier, and response data, and adding a relationship edge in the interaction relationship data store connecting the graph node based on the first interaction identifier with a graph node based on the second interaction identifier.
