A method for providing network configuration changes in a service provider environment includes, by a server computer of the service provider environment, selecting a plurality of scripts associated with a corresponding plurality of operations that enable configuration changes to one or more network devices within the service provider environment. A network change procedure is generated based on the selected plurality of scripts. Metadata is read for at least one script of the plurality of scripts in the network change procedure. State information is determined for the at least one script using the metadata. Based on the state information, automatic execution of at least one operation is performed to generate an operation result. A determination is made whether to perform a rollback of the automatic execution based on the operation result.

Automated network change management

A Change Management system provides change management functionality by using configuration information that specifies various types of modifications to perform to networking devices, types of monitoring to perform for the networking devices (e.g., executable commands to use to gather information about operations of the networking devices), types of automated responses to problems identified by the monitoring (e.g., rollback commands to remove modifications that were performed), etc. for controlling and monitoring changes to the networking devices. Such configuration information may be specified by, for example, a user who is associated with one or more such networking devices, including a user who is a client of a service provider environment that provides various types of computing resources to its users.

Detecting and managing changes in networking devices

Systems and methods for implementing network changes are described herein. In one aspect, a network change procedure may be comprised of a plurality of scripts that may implement a change in the network. In one embodiment, the deployment may be paused after the script has been executed. During the pause, a change management server may determine the impact of the change on the network. If the change had a positive effect, the change management server may execute another script to make another network change. However, if the change had a negative effect, the change management server may initiate one or more remedial actions.

Network change management

Target host computing devices are provisioned with a machine image that corresponds to an operating environment, software applications, and associated configurations. The machine image is organized in a manner that allows static portions of the machine image to be maintained in a designated static partition. The machine image is also organized in a manner that allows dynamic portions of the machine image to be maintained in a designed dynamic partition. A host management component identifies updates to the static portion of the machine image and transmits the update information to the host computing devices. In turn, the host computing devices maintain the update in the allocated secondary partitions. Thereafter, the host computing devices causes a switch from a designated primary static partition to the secondary static partition, such as via a kernel switch.
