Automated operating system patching using auto scaling group and persistent volumes

A system for updating an Operating System (OS) using cloud-based resources comprising:

• one or more processors;
• and
• a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors of a server computing system to:
• enable an auto-scaling group (ASG) to launch one or more instances based on a first machine image, the first machine image associated with a first Operating System (OS), wherein the ASG is associated with a stateful service and configured with a resource tag having a value similar to a value assigned to the stateful service;
• receive a second machine image associated with a second OS generated based on the first OS;
• and
• enable the ASG to terminate the one or more instances launched based on the first machine image and to launch one or more instances based on the second machine image, wherein the instances launched based on the first machine image and based on the second machine image are associated with persistent volumes.

A computer program product for updating an Operating System (OS) using cloud-based resources comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions to:

• enable an auto-scaling group (ASG) to launch one or more instances based on a first machine image, the first machine image associated with a first Operating System (OS), wherein the ASG is associated with a stateful service and configured with a resource tag having a value similar to a value assigned to the stateful service;
• receive a second machine image associated with a second OS generated based on the first OS;
• and
• enable the ASG to terminate the one or more instances launched based on the first machine image and to launch one or more instances based on the second machine image, wherein the instances launched based on the first machine image and based on the second machine image are associated with persistent volumes.
