Abstract

Embodiments of the present invention relate to methods and apparatuses for enabling cluster scaling. Specifically, there is disclosed a method of recording a context of configuration for an initial node of a cluster, comprising: retrieving at least one file to be used for configuring the initial node; and recording a context while configuring the initial node using the at least one file, the recorded context being information on the configuration of the initial node and to be used for enabling addition of a new node into the cluster. There is also disclosed a method of enabling addition of a new node into a cluster. Corresponding apparatuses are also disclosed. According to embodiments of the present invention, the efficiency of improving cluster scaling may be effectively improved.

Claims

1. A method of recording a context of configuration for an initial node of a cluster, comprising:

retrieving at least one file to be used for configuring the initial node; and

recording a context while configuring the initial node using the at least one file, the recorded context being information on the configuration of the initial node and to be used for enabling addition of a new node into the cluster.

2. The method according to claim 1, wherein recording a context while configuring the initial node using the at least one file comprises recording the context in at least one of:

the initial node, and a context repository associated with the cluster.

3. A method of enabling addition of a new node into a cluster, comprising:

accessing a context of an existing node of the cluster, the context being information on a configuration of the existing node while being added into the cluster; and

retrieving at least one file according to the context, wherein the at least one file is to be used for configuring the new node.

4. The method according to claim 3, wherein accessing the context of the existing node of the cluster further comprises:

accessing the context from a context repository associated with the cluster.

5. The method according to claim 3, wherein accessing the context of the existing node of the cluster further comprises:

accessing the context from the existing node.

6. The method according to claim 3, wherein retrieving at least one file according to the context comprises retrieving the at least one file from at least one of:

the existing node of the cluster, and a file repository associated with the cluster.

7. The method according to claim 3, wherein retrieving at least one file according to the context further comprises:

concurrently retrieving the at least one file.

8. The method according to claim 3, further comprising:

recording a context while configuring the new node using the at least one file.

9. The method according to claim 8, wherein recording the context while configuring the new node using the at least one file comprises recording the context in at least one of:

the new node, and a context repository associated with the cluster.
