US-20260127082-A1 - FAILOVER OF DOMAINS

Abstract

An approach of performing data center failover using an address that indicates a backup data center. The address includes common names indicating a data center with a domain and a backup datacenter with a replica of the domain. A cloud service provider can receive the address, establish a connection with an available data center, and failover to the backup data center if the data center with the connection becomes unavailable.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. nonprovisional application No. Ser. No. 18/050,457, entitled “Failover of Domains,” filed on Oct. 27, 2022, which claims priority to U.S. provisional application No. 63/273,823, entitled “Failover of Domains,” filed on Oct. 29, 2021, the disclosures of which are incorporated by reference herein in their entireties for all purposes. BACKGROUND A cloud service provider (CSP) can include multiple data centers that can provide services to users. Each of the data centers can have domains that can be accessed to provide services to the users. However, the data centers may have issues that can cause the data centers to become unavailable to the users. When a data center becomes unavailable when a user is making use of the data center, the user may be dropped and the services provided by the data center may become unavailable to the user. In some approaches, the user may be transferred to another data center that can provide services to the user. However, these legacy approaches of transferring a user to another data center can take a significant amount of time to transfer the user to another data center. SUMMARY An aspect of the present disclosure is directed to a method for failover of a domain, where the method may include providing, by a cloud service provider (CSP), access to a domain that resides in a first data center located in a first geographic region based at least in part on an address that indicates the first data center located in the first geographic region and a second data center located in a second geographic region. The method may further include determining, by the cloud service provider, that the first data center in the first geographic region has become unavailable, and determining, by the cloud service provider, that the second data center in the second geographic region is to be utilized as a backup data center for the domain based at least in part on the address. Further, the method may include providing, by the cloud service provider, access to a replica of the domain that resides in the second data center in the second geographic region based at least in part on the determination that the second data center in the second geographic region is to be utilized as the backup data center and the determination that the first data center in the first geographic region has become unavailable. An aspect of the present disclosure is directed to one or more non-transitory computer-readable media having instructions stored thereon, wherein the instructions, when executed by one or more processors, may cause a cloud service provider to provide access to a domain that resides in a first data center located in a first geographic region based at least in part on an address that indicates the first data center located in the first geographic region and a second data center located in a second geographic region. The instructions, when executed by the one or more processors, may further cause the cloud service provider to determine that the first data center located in the first geographic region has become unavailable, and determine that the second data center located in the second geographic region is to be utilized as a backup data center for the domain based at least in part on the address. Further, the instructions, when executed by the one or more processors, may cause the cloud service provider to provide access to a replica of the domain that resides in the second data center located in the second geographic region based at least in part on the determination that the second data center located in the second geographic region is to be utilized as the backup data center and the determination that the first data center located in the first geographic region has become unavailable. An aspect of the present disclosure is directed to a cloud service provider that may include one or more data centers located in one or more geographic regions to provide services to one or more user devices, and one or more processors to control access to the one or more data centers located in the one or more geographic regions. The one or more processors may cause access to be provided to a domain that resides in a first data center located in a first geographic region based at least in part on an address that indicates the first data center located in the first geographic region and a second data center located in a second geographic region. The one or more processors may further determine that the first data center located in the first geographic region has become unavailable, and determine that the second data center located in the second geographic region is to be utilized as a backup data center for the domain based at least in part on the address. Further, the one or more processors may cause access to be provided to a replica of the domain that resides in the second data center located in the second geographic region based at least in
