Abstract:
1. A method for isolating tenants in a multi-tenant cloud system, the method comprising: identifying, using a computer system, a plurality of tenants in the multi-tenant cloud system, wherein the plurality of tenants share computational resources in the multi-tenant cloud system; providing a plurality of racks including servers, wherein the servers provide the computational resources for the plurality of tenants; assigning, by the computer system, different portions of the servers in the plurality of racks to different domains; assigning, by the computer system, each of the different domains to a respective tenant of the plurality of tenants based on a wavelength division multiplexing (WDM), wherein the WDM uses a plurality of wavelength sets, each wavelength set including one or more wavelengths; associating, by the computer system, each of the plurality of wavelength sets with a different domain of the plurality of domains and with a different visual indicator identifying the domain for the wavelength set, wherein each of the plurality of visual indicators is physically attached to a respective one of the servers or slot housing the server to identify the domain to which the server is allocated; and controlling, by aggregation switches, each of the servers assigned to the different domains for isolating the plurality of tenants.
