Description

Apparatus and method for container deployment in a cloud computing environment

The following embodiments relate to an apparatus and method for container deployment in a cloud computing environment.

Cloud computing (English: cloud computing) is to provide system resources (IT resources) of virtualized computers through the cloud (Internet). As a type of Internet-based computing, it refers to a technology that processes information not with one's own computer but with another computer connected to the cloud (Internet). Provides shared computer processing resources and data to computers and other devices on demand. A model that enables ubiquitous, on-demand availability of computer system resources to configurable computing resources (e.g., computer networks, databases, servers, storage, applications, services, and intelligence), with minimal Administrative effort enables rapid provisioning and release.

A container is a thing that makes a logical partition (container) on the host OS and collects libraries or applications necessary to run an application into one so that it can be used as if it were a separate server. It logically separates the host OS's resources and is shared and used by multiple containers. Containers are characterized by being lightweight and operating at high speed because of low overhead.

In this case, the container arrangement device includes the number of nodes accommodated in each of the at least two or more node groups, the number of containers accommodated in the nodes included in each of the at least two or more node groups, and each of the at least two or more node groups. It is possible to monitor the number of reserved nodes for which the container is not accommodated.

The container arrangement apparatus relocates at least one node included in one node group among the at least two or more node groups to another node group based on the monitoring result (240).

Here, there is at least one node group that can no longer accommodate a container among a plurality of node groups, and a reserved node in which a container is not accommodated in at least one other node group among the plurality of node groups If included, the container arrangement device borrows a reserved node in which a container included in at least one other node group among the plurality of node groups is not accommodated and no longer contains any more containers among the plurality of node groups. can be relocated to an unacceptable node group.

The container arrangement device re-arranges the at least one node relocated to one node group among the at least two or more node groups based on the re-monitoring result in the node group before the relocation ( 260 ).

In this case, when the resource shortage of at least one node group that could no longer accommodate the container among the plurality of node groups is resolved, the container arrangement apparatus relocates the relocated at least one node among the plurality of node groups before relocating. You can redeploy it to a nodegroup.
