Synchronizing network configuration in a multi-tenant network

A computer system, comprising:

• one or more processors;
• one or more memory devices coupled to the one or more processors;
• one or more configuration managers;
• and
• one or more computer readable storage devices coupled to the one or more processors, wherein the one or more storage devices contain program code executable by the one or more processors via the one or more memory devices to implement a method of synchronizing network configuration in a multi-tenant network, the method comprising:
• receiving, by the one or more processors of a computer system, a first request to change a network status by a tenant of the multi-tenant network to a desired network configuration, the desired network configuration including a version number;
• validating, by the one or more processors of the computer system, the desired network configuration against a first network configuration;
• determining, by the one or more processors of the computer system, one or more configuration managers the first request to change impacts;
• attaching, by the one or more processors of the computer system;
• a tenant identifier to the first request to change, the tenant identifier corresponding to the tenant of the multi-tenant network;
• storing;
• by the one or more processors of the computer system, the first requested change in a data repository;
• sending, by the one or more processors of the computer system, a notification to each of the one or more configuration managers the first request to change impacts, wherein the one or more configuration managers are configured to manage at least one network device of the tenant of the multi-tenant network corresponding to the tenant identifier;
• receiving, by a first of the one or more configuration managers the first request to change impacts, the notification;
• requesting from the data repository, by the first of the one or more configuration managers, all changes pertaining to the tenant corresponding to the tenant identifier;
• de-multiplexing, by the first of the one or more configuration managers the requested change impacts, the requested changes corresponding to the tenant identifier;
• applying, by the first of the one or more configuration managers the requested change impacts, the desired configuration to the at least one network device of the tenant associated with the tenant identifier without applying the desired configuration to another network device of another tenant of the multi-tenant network;
• and
• ensuring, by the one or more processors of the computer system, that a failure in a requested configuration by a single tenant requester in the multi-tenant network does not impact the requested configuration on behalf of other tenants in the multi-tenant network.

A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, the computer readable program code comprising an algorithm that when executed by one or more processors of a computer system that includes one or more configuration managers, implements a method of synchronizing device configuration in a multi-tenant network, the method comprising:

• receiving, by the one or more processors of a computer system, a first request to change a network status by a tenant of the multi-tenant network to a desired network configuration, the desired network configuration including a version number;
• validating, by the one or more processors of the computer system, the desired network configuration against a first network configuration;
• determining, by the one or more processors of the computer system, one or more configuration managers the first request to change impacts;
• attaching, by the one or more processors of the computer system, a tenant identifier to the first request to change, the tenant identifier corresponding to the tenant of the multi-tenant network;
• storing, by the one or more processors of the computer system, the first requested change in a data repository;
• sending, by the one or more processors of the computer system, a notification to each of the one or more configuration managers the first request to change impacts, wherein the one or more configuration managers are configured to manage at least one network device of the tenant of the multi-tenant network corresponding to the tenant identifier;
• receiving, by a first of the one or more configuration managers the first request to change impacts, the notification;
• requesting from the data repository, by the first of the one or more configuration managers, all changes pertaining to the tenant corresponding to the tenant identifier;
• de-multiplexing, by the first of the one or more configuration managers the requested change impacts, the requested changes corresponding to the tenant identifier;
• applying, by the first of the one or more configuration managers the requested change impacts, the desired configuration to the at least one network device of the tenant associated with the tenant identifier without applying the desired configuration to another network device of another tenant of the multi-tenant network;
• and
• ensuring, by the one or more processors of the computer system, that a failure in a requested configuration by a single tenant requester in the multi-tenant network does not impact the requested configuration on behalf of other tenants in the multi-tenant network.
