Abstract: Embodiments of the present communications systems and methods may provide the capability for fast and reliable transitioning between the different versions of the service of the multi-node service deployed in the utility computing system. For example, in an embodiment, a computer-implemented method for data traffic distribution may comprise allocating a plurality of data traffic service network addresses to a load balancer service, wherein each data traffic service network address is associated with a different version of the load balancer service, receiving a plurality of data traffic flows, and distributing each data traffic flow to a version of the load balancer service based on a data traffic service network address of each data traffic flow.

Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include defining, for a request processing system, a first homogeneous auto-scaling group including a first monitored resource, a first set of processing systems, a first minimum threshold, a first maximum threshold, and a first system configuration. Subsequent to defining the first homogeneous auto-scaling group, a second auto-scaling group is defined for the request processing system, the second auto-scaling group including a second monitored resource different from the first monitored resource, a second set of processing systems, a second minimum threshold, a second maximum threshold, and a second system configuration different from the first system configuration. In embodiments of the present invention, a load balancer for the request processing system manages the first and the second sets of processing systems as a single heterogeneous auto-scaling group.

Abstract: Disclosed is a method for providing a public key for authenticating an integrated circuit. In the method, the integrated circuit obtains a hardware key and an integrated circuit identifier. The integrated circuit generates a derived key based on the hardware key using a key derivation function (KDF) shared with a manufacturing machine. The integrated circuit generates a private key and a corresponding public key using the derived key as an input to a deterministic function. The integrated circuit then provides the public key and the integrated circuit identifier to a partner service for authentication of the integrated circuit using an anonymized credential database to be provided to the partner service by a manufacturer.

Abstract: A revision control service is included in a hypervisor. The revision control service manages revision control operations relating virtual machine images transparently to the virtual machine. The revision control service interacts with a conventional revision control program, stores relevant revision control metadata external to the virtual machine image with file-level granularity, and synchronizes virtual machine operations with the revision control operations. From the perspective of the virtual machine, the revision control service provides a clean image from which to boot, without modification of the revision control program.

Abstract: A system and method for creating N customized disk images from N identical disk images. A computing system creates N identical disk images from a master image. The computing system customize a first identical disk image according to a customization written in customization scripts. While customizing the first identical disk image, the computing system monitors block-level operations applied on the first identical disk image. The computing system applies the monitored block-level operations simultaneously to other N?1 identical disk according to similar customizations written in customization scripts. After applying the block-level operations, the N identical disk images become N customized disk images. Identical Virtual Machines (VMs) operating in the N identical disk images become N customized VMs by operating based on the N customized disk images.

Abstract: A method for monitoring changes in at least two servers, that creates difference results that encapsulate effects of changes applied to file systems of at least two servers. These differences results are defined by predetermined creation rules. The method includes comparing the difference results between the at least two servers to detect differences in the respective difference results. These detected differences are defined in accordance with predetermined comparison rules. The method further includes: analyzing the detected differences in comparison results in accordance with predetermined analysis rules and indicating potential problems from the analyzed and detected differences.

Abstract: A method for eligibility list management in a distributed group membership system, including receiving an eligibility list change request with respect to an eligibility list of a group of computing elements, removing from a view of the group any active members in the group who are to be removed from the eligibility list as indicated by the eligibility list change request, preventing any of the members that are removed from the view from rejoining a view until the eligibility list change is applied to the eligibility list, applying the eligibility list change to the eligibility list, and establishing a new view for any active members in the group who are on the changed eligibility list.
