Abstract

A first cluster creates a cluster exchange object including identifiers of components of the first cluster and segments of data of the first cluster along with configuration data, such as access points and credentials. The first cluster transmits the object to a second cluster that instantiates copies of the components and retrieves the segments from the first cluster to become a replica of the second cluster. The second cluster may then commence execution upon failure of the primary cluster and restore the primary cluster. The primary cluster may send snapshot objects to the second cluster to communicate changes to the primary cluster and the snapshot objects may also be used to restore the primary cluster following failure. The components of a cluster may be represented in a directory structure and data describing a component may be retrieved in response to user interactions with a representation of the directory structure.

Dependent claims

An apparatus comprising:

a computer system including a plurality of processing devices and one or more memory devices operably coupled to the plurality of processing devices, the one or more memory devices storing executable code that, when executed by the plurality of processing devices, causes the plurality of processing devices to:
create, by a first cluster executing on the computer system, a snapshot object for the first cluster including one or more identifiers of one or more components that have changed in the first cluster, the one or more components being executable components executing in the first cluster;
transmit, by the first cluster, to a second cluster executing on the computer system, the snapshot object;
and
in response to the snapshot object, instantiate by the second cluster, copies of the one or more components on the second cluster such that the second cluster becomes a replica of the first cluster;
wherein the snapshot object is a second snapshot object having a second sequence number;
wherein the executable code, when executed by the plurality of processing devices, further causes the plurality of processing devices to restore the first cluster following failure of the first cluster by:
creating, by the first cluster, a clone snapshot object of the first cluster;
determining, by the first cluster, that data corresponding to a first snapshot object having a first sequence number lower than the second sequence number is present in the first cluster;
in response to determining that the data corresponding to the first snapshot object is present in the first cluster, transmitting, by the first cluster, the first sequence number to the second cluster;
in response to receiving the first sequence number, transmitting, by the second cluster, the second snapshot object to the first cluster;
receiving, by the first cluster, the second snapshot object from the second cluster;
and
instantiating, by the first cluster, the one or more components in the first cluster using the second snapshot object.

A method comprising:

creating, by a first cluster executing on a computer system, a snapshot object for the first cluster including one or more identifiers of one or more components that have changed in the first cluster, the one or more components being executable components executing in the first cluster;
transmitting, by the first cluster, to a second cluster executing on the computer system, the snapshot object;
and
in response to the snapshot object, instantiate by the second cluster, copies of the one or more components on the second cluster such that the second cluster becomes a replica of the first cluster;
wherein the snapshot object is a second snapshot object having a second sequence number, the method further comprising, following failure of the first cluster:
determining, by the first cluster, that data corresponding to a first snapshot object having a first sequence number that is lower than the second sequence number is present in the first cluster;
in response to determining that the data corresponding to the first snapshot object is present in the first cluster, transmitting, by the first cluster, the first sequence number to the second cluster;
in response to receiving the first sequence number, transmitting, by the second cluster, the second snapshot object to the first cluster;
receiving, by the first cluster, the second snapshot object from the second cluster;
and
instantiating, by the first cluster, the one or more components in the first cluster using the second snapshot object.
