Touch free disaster recovery
A Recovery as a Service (RaaS) system including a Configuration Management Database (CMDB), a Resource Planning System (RPS), a Recovery Execution System (RES), and an Asset Reservation System (ARS). A scope for a test or recovery is specified as one or more applications. In one implementation, the RPS can request, from the CMDB, identification of which protected resources are within the requested scope and request the ARS to only reserve assets within that scope. At time of test or disaster, the RES programmatically generates a recovery workflow and initiates its orchestration such as provisioning and/or configuring operating systems, file systems, networks, applications, and data, and executing startup processes. If there are exceptions to automated workflow, then operations personnel may perform corresponding manual operations such as through a ticketing system.
1. An automated method for providing Recovery as a Service (RaaS) to a protected site comprising:
prior to a time for executing a Disaster Recovery (DR) test,
at a Resource Planning System (RPS) executing on one or more data processors,
accepting an input specifying a DR test to be executed within the protected site, including at least a scope for the DR test and a designated time for the DR test;
requesting, from a Configuration Management DataBase (CMDB) executing on one or more data processors, identification of one or more protected resources within the scope of the DR test;
requesting, from an Asset Reservation System (ARS) executing on one or more data processors, a reservation for the one or more protected resources within the scope of the DR test at the designated time;
associating a reservation identifier with the reservation for the one or more protected resources within the scope of the DR test; and
presenting the reservation identifier to a user;
at the designated time for the DR test,
using the reservation identifier, determining a list of protected resources associated with the reservation identifier;
requesting a logical recovery configuration for resources available in a recovery site executing on one or more data processors;
programmatically generating a recovery workflow from the logical recovery configuration; and
executing, by one or more data processors, the recovery workflow to provide the recovery site.
2. The method of claim 1 wherein the scope for the DR test is specified as an application, without identifying specific assets needed to recover the application.
3. The method of claim 1 wherein the scope of the DR test identifies specific assets including servers, storage, and/or network hardware.
4. The method of claim 1 wherein the scope of the DR test identifies a business unit or location.
5. The method of claim 1 wherein the step of programmatically generating a recovery workflow further comprises the steps of:
obtaining configuration data for the protected resources within the scope of the DR test, and further executing on one or more data processors, for each protected resource:
a recovery task;
a configuration detection process;
an automation component detection process; and
wherein the automation component process executes at least one automation component including at least one subflow for executing the recovery task.
6. The method of claim 1 additionally comprising:
maintaining configuration data for the protected resources in the Configuration Management DataBase (CMDB);
periodically cloning the CMDB to a Disaster Recovery Configuration Management DataBase (DR-CMDB); and
wherein the step of requesting identification of one or more protected resources comprises querying the DR-CMDB to locate configuration data for the one or more protected resources within the scope of the DR test.
7. The method of claim 1 wherein the Asset Reservation System (ARS) further uses the reservation identifier for identifying a reservation for using the protected assets at the designated time.
8. The method of claim 1 wherein the step of programmatically generating a recovery workflow is performed by a Recovery Execution System (RES) executing on one or more data processors using the logical recovery configuration information.
9. The method of claim 8 wherein execution progress of the recovery workflow is reported by the RES and presented as an output to a user.
10. The method of claim 8 wherein the recovery workflow includes at least an operating system build phase and an application install phase.
11. The method of claim 8 wherein the recovery workflow further includes one or more of:
a virtual machine build phase,
an application restore from backup phase,
a storage configuration phase, a network configuration phase, or
an operating system restore phase.
12. The method of claim 1 additionally comprising:
a ticketing system, executing on one or more data processors, for handling exceptions to the recovery workflow.
13. The method of claim 1 further comprising:
storing a representation of the recovery workflow as a sequence of operations specified in a markup language file; and
executing the recovery workflow, by submitting the markup language file to an operations orchestration engine, the operations orchestration engine executing on one or more data processors.
14. The method of claim 1 additionally comprising:
at a time of disaster,
at the Resource Planning System (RPS) executing on one or more data processors,
receiving input identifying a disaster scope;
requesting, from the Configuration Management DataBase (CMDB) executing on one or more data processors, a list of protected resources associated with the disaster scope;
requesting a logical recovery configuration for resources available in a recovery site within the disaster scope;
programmatically generating, on one or more data processors, a disaster workflow from the logical recovery configuration; and
executing the disaster workflow on one or more data processors to provide the recovery site.
15. In a Recovery as a Service (RaaS) system executing on one or more data processors, the RaaS comprising a Configuration Management Database (CMDB), a Resource Planning System (RPS), a Recovery Execution System (RES), and an Asset Reservation System (ARS), a method comprising:
at the RPS executing on one or more data processors, the steps of:
receiving information about a future desired Disaster Recovery (DR) test at the RPS;
retrieving a list of protected items and presenting the protected items for selection, wherein the selection is specified as a scope for the DR test as one or more applications;
requesting, from the CMDB executing on one or more data processors, identification of which protected resources are within the scope of the DR test;
sending a request to the ARS executing on one or more data processors, the request asking to reserve physical assets that correspond to the protected resources that are within the scope of the DR test;
receiving a reservation identifier from the ARS and presenting it to a user;
at a time for the DR test,
at the RPS executing on one or more data processors;
receiving the reservation identifier from a user;
requesting, from the ARS, a list of the physical assets for the DR test as previously associated with the reservation identifier;
requesting, from the CMDB executing on one or more data processors, a logical recovery configuration for the DR test using the physical assets for the DR test;
requesting the RES, executing on one or more data processors, to programmatically generate a recovery workflow using the logical recovery configuration; and
requesting the RES, executing on one or more data processors, to initiate orchestration of the recovery workflow.
