Abstract: Implementing multiple load balancer drivers for a single load balancer is disclosed. A first request directed to a load balancer to load balance requests based on a first request selection instruction is received. A first particular load balancer driver is selected from a plurality of load balancer drivers based on a load balancer table that correlates request selection instructions to corresponding load balancer drivers of the plurality of load balancer drivers. Subsequent requests that are encompassed by the first request selection instruction directed to the load balancer are caused to be load balanced by the first particular load balancer driver.

Abstract: Virtualized computing resources can be managed in a cloud computing environment. For example, a system can receive input indicating that a cloud computing environment is to be reverted back to a prior state prior to an event occurring. Based on the input, the system can determine actions that were performed in the cloud computing environment in response to the event. Each action can involve a creation, a modification, or a deletion of a virtualized computing resource in the cloud computing environment. The system can determine a particular order in which the actions were performed by analyzing timestamps corresponding to the actions. The system can then revert the cloud computing environment back to the prior state by performing an inverse of each action in the plurality of actions in a reverse order to the particular order.

Abstract: Dynamically revising an in-process build is disclosed. A build system receives a build configuration comprising information that defines a plurality of successive stages. Each stage includes at least one step, and one or more of the stages include a plurality of successive steps. The build configuration defines a build process that, when completed, alters a state of a storage device. The build system initiates a build process sequence on the build configuration. The build system, after initiating the build process sequence, receives notification of a desire to add a revision to a particular stage of the plurality of stages defined in the build configuration. A determination is made that performance of the particular stage has or has not begun. In response to the determination, a subsequent build process action is performed.

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.

Abstract: A system and method to facilitate backporting of bug patches to earlier versions of a project are disclosed. In one implementation, an indication that an error has been fixed for a version of a project managed by a code review system is received. An indication that a patch for the error has been applied to the earlier version of the project is received from the code review system. A message is sent to at least one participant of the project identifying the patch and the earlier version of the project, and indicating that the patch has been successfully applied to the earlier version of the project.
