  • Patent number: 11099824
    Abstract: Provided are methods and systems for transition between a current cloud-based code environment and an updated cloud-based code environment. A method for transition between a current cloud-based code environment and an updated cloud-based code may commence with generating a steering policy. The steering policy may include a set of rules to guide steering decisions between a current cloud-based code environment and an updated cloud-based code environment. The method may further include sending the steering policy to a steering server. The steering server may make steering decisions to steer, based on the steering policy, service requests between the current cloud-based code environment and the updated cloud-based code environment. The method may continue with receiving feedback concerning actual steering decisions made by the steering server. The method may further include automatically adjusting the steering policy in response to the feedback.

  • Patent number: 10817334
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for data stream processing. One method performed by a stream manager in a group of containers including streaming processes and stream managers includes receiving a first data streaming object of the data streaming objects from a first component in the group of containers; determining whether to process the first data streaming object; in response to determining to process the first data streaming object processing the first data streaming object and routing the first data streaming object; and in response to determining not to process the first data streaming object, routing the first data streaming object.

  • Patent number: 10613903
    Abstract: A system and method for data stream processing. Two or more instances are connected as a topology, wherein at least one of the instances is a spout and at least one of the instances is a bolt. The topology is submitted to a scheduler, wherein the service scheduler receives resource offers from a cluster manager representing computing resources available on one or more of cluster nodes and determines resources to accept and computations to run on the accepted computing resources. The topology is scheduled as one or more jobs, wherein each job includes two or more containers, including a first container and a second container, the first container including a topology master and the second container including a stream manager and one or more stream processing system (SPS) instances, wherein each SPS instance represents one of the instances in the topology.

  • Patent number: 10268467
    Abstract: Policy-driven management of application traffic is provided for services to cloud-based applications. A steering policy refers to a set of rules is generated for a deployment from a current code environment to one or more replicated code environment differing in some key respect. The steering policy can guide steering decisions between the current and updated code environments. A steering server uses the steering policy to make decisions about whether to send service requests to the current code environment or the updated code environment. Feedback concerning actual steering decisions made by the steering server is received (e.g., performance metrics). The steering policy is automatically adjusted in response to the feedback.
