Abstract

A method and system for managing a computing cluster including hosting a plurality of machines in a networked computing cluster, wherein the plurality of machines include service instances running on hosts, where the services have configured machine state; and wherein machine state includes configuration data and software of the machine; integrating the plurality of machines of the cluster with at least one configuration controller component; and the at least one configuration controller component, altering the machine state of at least one service instance.

Claims

1. A method comprising:

at a first computer, receiving a group comprising a group configuration and a group definition;

storing an initial state of the group at a database;

at the first computer, receiving an instruction to start the group in a cloud telephony system; and

from the first computer, launching the group at a computing cluster.

2. The method of claim 1, further comprising compiling the group definition into an internal representation at the first computer.

3. The method of claim 1, wherein the group definition comprises a domain specific language.

4. The method of claim 3, wherein group configuration comprises a set of rules comprising a condition class and an action class.

5. The method of claim 1, wherein the group configuration and the group definition are stateless.

6. The method of claim 1, further comprising from the first computer, launching a monitoring loop configured to monitor the database and the computing cluster.

7. The method of claim 6, further comprising applying a rules engine at the monitoring loop, wherein the rules engine comprises a stateless application of the set of rules.

8. The method of claim 7, further comprising checking the group status at the computing cluster by the monitoring loop.

9. The method of claim 8, further comprising adjusting group status at the computing cluster by the monitoring loop in accordance with the rules engine in response to one of a change in state of the group at one of the database or the computing cluster.

10. The method of claim 6, further comprising checking the group status at the database by the monitoring loop.

11. The method of claim 10, further comprising adjusting the group status at the database by the monitoring loop in accordance with the rules engine in response to one of a change in state of the group at one of the database or the computing cluster.

12. The method of claim 6, wherein the monitoring loop is an infinite loop.

13. A method comprising:

at a first computer, receiving a group comprising a group configuration and a group definition, wherein the group configuration comprises a set of rules;

storing an initial state of the group at a database;

at the first computer, receiving an instruction to start the group in a cloud telephony system;

from the first computer, launching the group at a computing cluster;

at the first computer, generating a monitoring loop comprising a rules engine for stateless application of the set of rules; and

checking the group status at the computing cluster by the monitoring loop.

14. The method of claim 13, further comprising checking the group status at the database by the monitoring loop.

15. The method of claim 14, further comprising adjusting the group status at one of the database or the computing cluster by the monitoring loop in response to one of a change in state of the group at one of the database or the computing cluster.
