Method for deploying product applications within virtual machines onto on-premises and public cloud infrastructures
A method for deploying product applications within virtual machines onto on-premises and public cloud infrastructures. Specifically, the disclosed method proposes a migration scheme of virtual machine images (configured at least with product applications and guest operating systems) from an on-premises infrastructure to a public cloud infrastructure. Further, the migration scheme considers two workflows—a normal workflow contingent on the public cloud infrastructure having up-to-date support for the guest operating systems; and an exception workflow contingent on the public cloud infrastructure lacking up-to-date support for the guest operating systems.
1. A method for deploying product applications within virtual machines from an on-premises infrastructure onto a public cloud infrastructure, the method comprising:
receiving, by the public cloud infrastructure and from the on-premises infrastructure, an on-premises product virtual machine image comprising a product application;
performing, by the public cloud infrastructure and using a virtual machine image import tool configured to facilitate virtual machine image importation, a first import attempt of the on-premises product virtual machine image into a cloud virtual machine image repository of the public cloud infrastructure;
obtaining, by the public cloud infrastructure and based on a failure result of the first import attempt provided by the virtual machine import tool, a cloud product virtual machine instance; and
triggering, by the public cloud infrastructure, a virtual machine snapshot of the cloud product virtual machine instance to produce a cloud product virtual machine image comprising the product application.
2. The method of claim 1 , wherein the on-premises product virtual machine image further comprises a patched guest operating system (OS) distribution.
3. The method of claim 2 , wherein the first import attempt fails based on the public cloud infrastructure lacking up-to-date support for the patched guest OS distribution.
4. The method of claim 1 , wherein to obtain the cloud product virtual machine instance, the method further comprises:
initiating, by the public cloud infrastructure, a cloud kick-start virtual machine instance comprising a guest operating system (OS) distribution;
applying, by the public cloud infrastructure and to the guest OS distribution, a latest OS patch to obtain a patched cloud kick-start virtual machine instance; and
installing, by the public cloud infrastructure and using an application installer configured for software application installation, the product application within the patched cloud kick-start virtual machine instance to obtain the cloud product virtual machine instance.
5. The method of claim 4 , wherein the cloud kick-start virtual machine instance is created from a cloud kick-start virtual machine image that comprises the guest OS distribution.
6. The method of claim 5 , the method further comprising:
prior to initiating the cloud kick-start virtual machine instance:
performing, by the public cloud infrastructure and using the virtual machine image import tool, a second import attempt of an on-premises kick-start virtual machine image into the cloud virtual machine image repository; and
obtaining, by the public cloud infrastructure and based the second import attempt succeeding, the cloud kick-start virtual machine image from the on-premises kick-start virtual machine image.
7. The method of claim 6 , wherein the on-premises kick-start virtual machine image comprises the guest OS distribution, wherein the second import attempt succeeds based on the public cloud infrastructure having up-to-date support for the guest OS distribution.
8. The method of claim 6 , the method further comprising:
prior to performing the second import attempt:
submitting, by the public cloud infrastructure and based on the first import attempt failing, an import failure notification to the on-premises infrastructure; and
receiving, by the public cloud infrastructure and from the on-premises infrastructure and in response to submitting the import failure notification, the on-premises kick-start virtual machine image, the latest OS patch, and the application installer.
9. The method of claim 1 , the method further comprising:
receiving, by the public cloud infrastructure and from the on-premises infrastructure, a second on-premises product virtual machine image comprising a second product application;
performing, by the public cloud infrastructure and using the virtual machine image import tool a second import attempt of the second on-premises product virtual machine image into the cloud virtual machine image repository; and
obtaining, by the public cloud infrastructure and based on the second import attempt succeeding and from the second on-premises product virtual machine image, a second cloud product virtual machine image comprising the second product application.
10. The method of claim 9 , wherein the second on-premises product virtual machine image further comprises a guest operating system (OS) distribution, wherein the second import attempt succeeds based on the public cloud infrastructure having up-to-date support for the guest OS distribution.
11. A non-transitory computer readable medium (CRM) comprising computer readable program code, which when executed by a computer processor, enables the computer processor to perform a method for deploying product applications within virtual machines from an on-premises infrastructure onto a public cloud infrastructure, the method comprising:
receiving, by the public cloud infrastructure and from the on-premises infrastructure, an on-premises product virtual machine image comprising a product application;
performing, by the public cloud infrastructure and using a virtual machine image import tool configured to facilitate virtual machine image importation, a first import attempt of the on-premises product virtual machine image into a cloud virtual machine image repository of the public cloud infrastructure;
obtaining, by the public cloud infrastructure and based on a failure result of the first import attempt provided by the virtual machine import tool, a cloud product virtual machine instance; and
triggering, by the public cloud infrastructure, a virtual machine snapshot of the cloud product virtual machine instance to produce a cloud product virtual machine image comprising the product application.
12. The non-transitory CRM of claim 11 , wherein the on-premises product virtual machine image further comprises a patched guest operating system (OS) distribution.
13. The non-transitory CRM of claim 12 , wherein the first import attempt fails based on the public cloud infrastructure lacking up-to-date support for the patched guest OS distribution.
14. The non-transitory CRM of claim 11 , wherein to obtain the cloud product virtual machine instance, the method further comprises:
initiating, by the public cloud infrastructure, a cloud kick-start virtual machine instance comprising a guest operating system (OS) distribution;
applying, by the public cloud infrastructure and to the guest OS distribution, a latest OS patch to obtain a patched cloud kick-start virtual machine instance; and
installing, by the public cloud infrastructure and using an application installer configured for software application installation, the product application within the patched cloud kick-start virtual machine instance to obtain the cloud product virtual machine instance.
15. The non-transitory CRM of claim 14 , wherein the cloud kick-start virtual machine instance is created from a cloud kick-start virtual machine image that comprises the guest OS distribution.
16. The non-transitory CRM of claim 15 , the method further comprising:
prior to initiating the cloud kick-start virtual machine instance:
performing, by the public cloud infrastructure and using the virtual machine image import tool, a second import attempt of an on-premises kick-start virtual machine image into the cloud virtual machine image repository; and
obtaining, by the public cloud infrastructure and based the second import attempt succeeding, the cloud kick-start virtual machine image from the on-premises kick-start virtual machine image.
17. The non-transitory CRM of claim 16 , wherein the on-premises kick-start virtual machine image comprises the guest OS distribution, wherein the second import attempt succeeds based on the public cloud infrastructure having up-to-date support for the guest OS distribution.
18. The non-transitory CRM of claim 16 , the method further comprising:
prior to performing the second import attempt:
submitting, by the public cloud infrastructure and based on the first import attempt failing, an import failure notification to the on-premises infrastructure; and
