Migration of cloud-based software application
A method for migrating a virtual desktop may include provisioning a first virtual machine to host the virtual desktop. The first virtual machine may be provisioned to include a first operating system disk and a first identity disk. A snapshot of the first operating system disk may be generated. The virtual desktop may be migrated to a second virtual machine by at least replacing a second operating system disk of the second virtual machine with the first operating system disk. The first identity disk of the first virtual machine and a second identity disk of the second virtual machine may remain unchanged by the migration. Related systems and articles of manufacture are also provided.

generate a snapshot of the first operating system disk, the snapshot comprising data capturing a state of the first operating system disk at a particular point in time; and
migrate the application to a second virtual machine hosted in a different data center than the first virtual machine, the migration including replacement of a second operating system disk of the second virtual machine with use of the snapshot of the first operating system disk while a first identity disk of the first virtual machine and a second identity disk of the second virtual machine remain unchanged by the migration of the application.
2. The system of claim 1 , wherein the application comprises a virtual desktop configured to provide, at a client device communicatively coupled with at least the first virtual machine or the second virtual machine, a desktop operating system.
3. The system of claim 2 , wherein the first operating system disk stores data associated with the virtual desktop, and wherein the data includes an operating system, one or more applications, and a user data.
4. The system of claim 2 , wherein the virtual desktop comprises a static virtual desktop configured to retain one or more changes applied to the virtual desktop upon restarting the first virtual machine or the second virtual machine hosting the virtual desktop.
5. The system of claim 1 , wherein the first virtual machine is provisioned with the first identity disk storing a first data, wherein the first data provides the first virtual machine with a first identity, wherein the second virtual machine is provisioned with the second identity disk storing a second data, wherein the second data provides the second virtual machine with a second identity different than the first of the first virtual machine.
6. The system of claim 1 , wherein the first virtual machine is included in a first data center and the second virtual machine is included in a second data center.
7. The system of claim 6 , wherein the first data center and the second data center are included in a same region or different regions, and wherein the regions comprise one or more data centers within a latency-defined perimeter and connected through a dedicated regional low-latency network.
8. The system of claim 6 , wherein the application is migrated in response to the first data center having performance below a threshold or the second data center having a better performance than the first data center.
9. The system of claim 6 , wherein the application is migrated in response to an outage at the first data center.
10. The system of claim 1 , wherein the migrating of the application further includes placing the second virtual machine in a maintenance mode or powering off the second virtual machine prior to replacement of the second operating system disk.
11. The system of claim 1 , wherein the provisioning of the first virtual machine includes providing a first catalog including the first virtual machine.
12. The system of claim 1 , wherein the snapshot of the first operating system disk is generated in response to a request to migrate the virtual desktop.
13. The system of claim 1 , wherein the snapshot of the first operating system disk is generated based on a schedule or a periodic intervals.
14. A computer-implemented method, comprising:
provisioning a first virtual machine to host an application, the first virtual machine including a first operating system disk;
generating a snapshot of the first operating system disk, the snapshot comprising data capturing a state of the first operating system disk at a particular point in time; and
migrating the application to a second virtual machine hosted in a different data center than the first virtual machine, the migration including replacement of a second operating system disk of the second virtual machine with use of the snapshot of the first operating system while a first identity disk of the first virtual machine and a second identity disk of the second virtual machine remain unchanged by the migration of the application.
15. The method of claim 14 , wherein the application comprises a virtual desktop configured to provide, at a client device communicatively coupled with at least the first virtual machine or the second virtual machine, a desktop operating system.
16. The method of claim 15 , wherein the first operating system disk stores data associated with the virtual desktop, and wherein the data includes an operating system, one or more applications, and a user data.
17. The method of claim 15 , wherein the virtual desktop comprises a static virtual desktop configured to retain one or more changes applied to the virtual desktop upon restarting the first virtual machine or the second virtual machine hosting the virtual desktop.
18. The method of claim 14 , wherein the first virtual machine is provisioned with the first identity disk storing a first data, wherein the first data provides the first virtual machine with a first identity, wherein the second virtual machine is provisioned with the second identity disk storing a second data, wherein the second data provides the second virtual machine with a second identity different than the first of the first virtual machine.
19. The method of claim 14 , wherein the first virtual machine is included in a first data center and the second virtual machine is included in a second data center, wherein the first data center and the second data center are included in a same region or different regions, and wherein the regions comprise one or more data centers within a latency-defined perimeter and connected through a dedicated regional low-latency network.
20. A non-transitory computer readable medium storing instructions, which when executed by at least one data processor, result in operations comprising:
provisioning a first virtual machine to host an application, the first virtual machine including a first operating system disk;
generating a snapshot of the first operating system disk, the snapshot comprising data capturing a state of the first operating system disk at a particular point in time; and
migrating the application to a second virtual machine hosted in a different data center than the first virtual machine, the migration including replacement of a second operating system disk of the second virtual machine with use of the snapshot of the first operating system disk while a first identity disk of the first virtual machine and a second identity disk of the second virtual machine remain unchanged by the migration of the application.
21. A system, comprising:
