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.

Mechanisms for selecting node upgrade order

Techniques are disclosed relating to upgrade groups. A node of a computer system may access metadata assigned to the node during deployment of the node. The node may be one of a plurality of nodes associated with a service that is implemented by the computer system. The node may perform an operation on the metadata to derive a group identifier for the node and the group identifier may indicate the node's membership in one of a set of groups of nodes managed by the service. The node may then store the group identifier in a location accessible to the service.

Mechanisms for grouping nodes

Techniques are disclosed pertaining to migrating a database between different storage clusters. A computer system identifies a current state of the database that is managed by a database application that enables a client application to access data of the database stored at a first storage cluster. The computer system copies first particular data of the database that is associated with the current state from the first storage cluster to a second storage cluster. After the copying, the computer system transitions the database application into a read-only mode in which it processes read but not write traffic. The computer system copies, from the first storage cluster to the second storage cluster, second particular data of the database that was generated by the database application during the copying of the first particular data. The computer system may also instantiate another instance of the database application in association with the second storage cluster.
