Network configuration of top-of-rack switches across multiple racks in a data center

A method comprising:

• connecting top-of-rack (TOR) switches to a network fabric of at least one data center, wherein each TOR switch corresponds to a respective rack of the at least one data center, and is configured to provide access to the network fabric for computing devices mounted in the respective rack;
• receiving, from a client device via a portal, a request to configure a first rack of the at least one data center;
• receiving, from the client device, configuration data for at least one first virtual network to be accessed by a first computing device mounted in the first rack;
• and
• in response to receiving the configuration data, configuring a first TOR switch of the first rack, the configuring including associating the at least one first virtual network with the first TOR switch.

A system comprising:

• a network fabric to transmit data in at least one data center, wherein the at least one data center includes racks for mounting servers connected to the network fabric;
• network switches connected to the network fabric, wherein each network switch corresponds to a respective one of the racks;
• a data store to store configuration data for the network switches;
• at least one processing device;
• and
• memory containing instructions configured to instruct the at least one processing device to:
• receive, via a portal from a client device, a request to create a computing environment supported on a plurality of racks connected by the network fabric, the plurality of racks including a first rack for mounting a physical server configured to communicate with a physical server of a second rack in the computing environment;
• create at least one virtual network in the computing environment;
• and
• configure at least one of the network switches to associate the at least one virtual network with the physical server.
