Abstract
A processing device of a system may determine that a new service virtual machine (VM) image is available, the new service VM image comprising an update for a current service VM image. The system may identify a first instance of a first service VM that is presently running, wherein the first instance of the first service VM was created from the current service VM image and has a floating internet protocol (IP) address. The system may further create a second instance of the first service VM using the new service VM image, transfer active sessions of the first instance of the first service VM to the second instance of the first service VM, and reassign the floating IP address from the first instance of the first service VM to the second instance of the first service VM.
