Abstract

The systems and methods provide for migrating such applications to cloud storage by automating a continuous replication of changes made to the DBMS from the DBMS to an associated cloud instance. For example, the systems and methods facilitate the migration of the DBMS via multiple processes performing in parallel - a process to create and provision a new machine instance (e.g., an EC2 instance), a process to clone and transfer parameters of the operating system/software of the DBMS, and a process that backs up and/or captures the application data of the DBMS.

Claims

1. A system, comprising:

at least one processor;

at least one data storage device coupled to the at least one processor and storing instructions for migrating a database management system to cloud storage, wherein the process comprises;

capturing configuration details from a source machine of the database management system,

wherein the captured configuration details include CPU information, memory information, network interface card information, and data storage mount point information;

generating a new machine instance of a virtual machine within cloud storage, wherein generating the new machine instance of the virtual machine includes generating a new machine instance having configuration parameters based on the captured configuration details of the source machine, including machine configuration parameters, storage configuration parameters, and software configuration parameters;

cloning the database management system to the new machine instance of the virtual machine within the cloud storage,

wherein the cloning the database management system to the new machine instance of the virtual machine includes mounting provisioned data volumes, configuring storage software, and configuring database application software to the new machine instance;

capturing application data from the source machine; and

providing the captured application data to the cloned database management system at the new machine instance of the virtual machine via a live synchronization application that maintains synchronization between the source machine and the new machine.

2. The system of claim 1, wherein providing the captured application data to the cloned database management system at the new machine instance of the virtual machine includes providing the application data to the new machine instance of the virtual machine by replicating, via a running live synchronization process, an application configuration to the new machine instance of the virtual machine.

3. The system of claim 1, wherein capturing application data from the source machine includes creating a full backup of the application data from the source machine.

4. The system of claim 1, wherein cloning the database management system to the new machine instance of the virtual machine within the cloud storage includes recreating data directories of the database management system on the source machine.

5. The system of claim 1, wherein providing the captured application data to the cloned database management system at the new machine instance of the virtual machine includes executing an application instance configuration script for the application data.

6. The system of claim 1, wherein providing the captured application data to the cloned database management system at the new machine instance of the virtual machine via a live synchronization application includes:

creating configuration files with associated parameters for the application data;

creating application directories for the new machine instance;

retrieving the configuration files on the source machine; and

replicating, via a running live synchronization process, the application configuration to the new machine instance of the virtual machine.

8. The method of claim 1, wherein providing the captured application data to the cloned database management system at the new machine instance of the virtual machine includes:

creating configuration files with associated parameters for the application data;

creating application directories for the new machine instance;

retrieving the configuration files on the source machine; and

replicating, via a running live synchronization process, the application configuration to the new machine instance of the virtual machine.

7. A method for migrating a database management system to cloud storage, the method comprising:

capturing configuration details from a source machine of the database management system;

generating a new machine instance of a virtual machine within cloud storage;

cloning the database management system to the new machine instance of the virtual machine within the cloud storage;

capturing application data from the source machine; and

providing the captured application data to the cloned database management system at the new machine instance of the virtual machine.

9. The method of claim 7, wherein providing the captured application data to the cloned database management system at the new machine instance of the virtual machine includes providing the application data to the new machine instance of the virtual machine via a synchronization application.

10. The method of claim 7, wherein capturing application data from the source machine includes creating a full backup of the application data from the source machine.

11. The method of claim 7, wherein cloning the database management system to the new machine instance of the virtual machine within the cloud storage includes recreating data directories of the database management system on the source machine.

12. The method of claim 7, wherein providing the captured application data to the cloned database management system at the new machine instance of the virtual machine includes executing an application instance configuration script for the application data.

13. The method of claim 7, wherein capturing configuration details from a source machine of the database management system, generating a new machine instance of a virtual machine within cloud storage, and cloning the database management system to the new machine instance of the virtual machine within the cloud storage are all performed in parallel to one another. 14, The method of claim 7, cloning the database management system to the new machine instance of the virtual machine within the cloud storage includes mounting provisioned data volumes to the new machine instance of the virtual machine.
