Decommissioning disaster recovery for a cloud based application
A method may include disabling disaster recovery for a cloud-based application by determining that a domain name system (DNS) service has been reconfigured to map a custom domain of the cloud-based application to a uniform resource locator (URL) of a first instance of the cloud-based application deployed at a first cloud platform landscape instead of a URL of a global traffic management (GTM) cluster. The GTM cluster may be reconfigured to remove configurations for directing, based on an availability of the first instance of the cloud-based application, requests for the cloud-based application to the first instance of the cloud-based application and/or a second instance of the cloud-based application deployed at the second cloud platform landscape. The DNS service and/or the GTM cluster may be reconfigured such that future requests for the cloud-based application are routed to the first instance of the cloud-based application and not the GTM cluster.
1. A system, comprising:
at least one data processor; and
at least one memory storing instructions, which when executed by the at least one data processor, result in operations comprising:
receiving, from a client, a request to disable disaster recovery for a cloud-based application, the cloud-based application being deployed as a first instance of the cloud-based application at a first cloud platform and a second instance of the cloud-based application at a second cloud platform;
responding to the request to disable disaster recovery by at least determining that a domain name system (DNS) service has been reconfigured to map a custom domain of the cloud-based application to a uniform resource locator (URL) of the first instance of the cloud-based application instead of a URL of a global traffic management (GTM) cluster, the GTM cluster being configured to direct, based at least on an availability of the first instance of the cloud-based application, one or more requests for the cloud-based application to the first instance of the cloud-based application and/or the second instance of the cloud-based application; and
upon determining that the DNS service has been reconfigured to map the custom domain of the cloud-based application to the URL of the first instance of the cloud-based application, reconfiguring the GTM cluster to at least remove, from the GTM cluster, configurations for directing the one or more requests for the cloud-based application to the first instance of the cloud-based application and/or the second instance of the cloud-based application based at least on the availability of the first instance of the cloud-based application.
2. The system of claim 1 , further comprising:
determining that the first instance of the cloud-based application is operational subsequent to the reconfiguration of the GTM cluster and/or the DNS service; and
in response to the first instance of the cloud-based application being operational, reconfiguring the first cloud platform and/or the second cloud platform to at least cease a replication of configurations and/or data from the first cloud platform to the second cloud platform.
3. The system of claim 2 , wherein the reconfiguration of the first cloud platform and/or the second cloud platform further includes removing, from the second cloud platform, the second instance of the cloud-based application.
4. The system of claim 3 , wherein the removing of the second instance of the cloud-based application from the second cloud platform includes removing, from a database at the second cloud platform, data associated with the first instance of the cloud-based application, and wherein the data is replicated from another database at the first cloud platform to the database at the second cloud platform.
5. The system of claim 1 , wherein the DNS service includes a canonical name (CNAME) record mapping the custom domain of the cloud-based application to the URL of the GTM cluster while the disaster recovery is enabled for the cloud-based application, and wherein the DNS service is reconfigured by at least modifying the CNAME record to map the custom domain of the cloud-based application to the URL of the first instance of the cloud-based application instead of the URL of the GTM cluster.
6. The system of claim 5 , wherein the one or more requests for the cloud-based application are routed, based at least on the modified CNAME record, to the first instance of the cloud-based application, and wherein the modifying of the CNAME record prevents the one or more requests for the cloud-based application from being routed to the GTM cluster.
7. The system of claim 1 , wherein the second instance of the cloud-based application comprises a fully operational copy of the first instance of the cloud-based application.
8. The system of claim 1 , wherein the GTM cluster is configured to route, to the second instance of the cloud-based application, the one or more requests for the cloud-based application based at least on the first instance of the cloud-based application being unavailable.
9. The system of claim 1 , wherein the request from the client comprises a ticket, and wherein the ticket is updated based at least on whether the DNS service has been reconfigured to map the custom domain of the cloud-based application to the URL of the first instance of the cloud-based application.
10. The system of claim 9 , wherein the ticket is further updated to notify the client that the disaster recovery has been disabled for the cloud-based application.
11. A computer-implemented method, comprising:
receiving, from a client, a request to disable disaster recovery for a cloud-based application, the cloud-based application being deployed as a first instance of the cloud-based application at a first cloud platform and a second instance of the cloud-based application at a second cloud platform;
responding to the request to disable disaster recovery by at least determining that a domain name system (DNS) service has been reconfigured to map a custom domain of the cloud-based application to a uniform resource locator (URL) of the first instance of the cloud-based application instead of a URL of a global traffic management (GTM) cluster, the GTM cluster being configured to direct, based at least on an availability of the first instance of the cloud-based application, one or more requests for the cloud-based application to the first instance of the cloud-based application and/or the second instance of the cloud-based application; and
upon determining that the DNS service has been reconfigured to map the custom domain of the cloud-based application to the URL of the first instance of the cloud-based application, reconfiguring the GTM cluster to at least remove, from the GTM cluster, configurations for directing the one or more requests for the cloud-based application to the first instance of the cloud-based application and/or the second instance of the cloud-based application based at least on the availability of the first instance of the cloud-based application.
12. The method of claim 11 , further comprising:
determining that the first instance of the cloud-based application is operational subsequent to the reconfiguration of the GTM cluster and/or the DNS service; and
in response to the first instance of the cloud-based application being operational, reconfiguring the first cloud platform and/or the second cloud platform to at least cease a replication of configurations and/or data from the first cloud platform to the second cloud platform.
13. The method of claim 12 , wherein the reconfiguration of the first cloud platform and/or the second cloud platform further includes removing, from the second cloud platform, the second instance of the cloud-based application.
