Publication number: 20210392185Abstract: A service provider may apply customer-selected or customer-defined auto-scaling policies to a cluster of resources (e.g., virtualized computing resource instances or storage resource instances in a MapReduce cluster). Different policies may be applied to different subsets of cluster resources (e.g., different instance groups containing nodes of different types or having different roles). Each policy may define an expression to be evaluated during execution of a distributed application, a scaling action to take if the expression evaluates true, and an amount by which capacity should be increased or decreased. The expression may be dependent on metrics emitted by the application, cluster, or resource instances by default, metrics defined by the client and emitted by the application, or metrics created through aggregation. Metric collection, aggregation and rules evaluation may be performed by a separate service or by cluster components. An API may support auto-scaling policy definition.Type: ApplicationFiled: June 18, 2021Publication date: December 16, 2021Applicant: Amazon Technologies, Inc.Inventors: Jonathan Daly Einkauf, Luca Natali, Bhargava Ram Kalathuru, Saurabh Dileep Baji, Abhishek Rajnikant Sinha

Publication number: 20210089433Abstract: A method for evaluating a build of a computer-implemented game is disclosed. An evaluation request is received. The evaluation. request includes an identification of the build, data describing one or more behaviors for the build, and data describing one or more tests. One or more simulations of playing of the build are performed using the one or more behaviors. One or more metrics ate extracted from the simulations. Each of the one or more metrics measures an aspect of the computer-implemented game. One or more tests are applied to the one or more metrics to evaluate an adherence of the build to the one or more tests. A display of the evaluation is caused to be displayed in a user interface of a client device.Type: ApplicationFiled: September 21, 2020Publication date: March 25, 2021Inventors: Mohamed Marwan A. Mattar, Shuo Diao, William Harris Kennedy, Souranil Sen, Jason Aaron Greco, Saurabh Dileep Baji, Danny Lange

Patent number: 10936432Abstract: Methods, systems, and computer-readable media for implementing a fault-tolerant parallel computation framework are disclosed. Execution of an application comprises execution of a plurality of processes in parallel. Process states for the processes are stored during the execution of the application. The processes use a message passing interface for exchanging messages with one other. The messages are exchanged and the process states are stored at a plurality of checkpoints during execution of the application. A final successful checkpoint is determined after the execution of the application is terminated. The final successful checkpoint represents the most recent checkpoint at which the processes exchanged messages successfully. Execution of the application is resumed from the final successful checkpoint using the process states stored at the final successful checkpoint.Type: GrantFiled: September 24, 2014Date of Patent: March 2, 2021Assignee: Amazon Technologies, Inc.Inventors: Tin-Yu Lee, Rejith George Joseph, Scott Michael Le Grand, Saurabh Dileep Baji

Patent number: 10659523Abstract: At the request of a customer, a distributed computing service provider may create multiple clusters under a single customer account, and may isolate them from each other. For example, various isolation mechanisms (or combinations of isolation mechanisms) may be applied when creating the clusters to isolate a given cluster of compute nodes from network traffic from compute nodes of other clusters (e.g., by creating the clusters in different VPCs); to restrict access to data, metadata, or resources that are within the given cluster of compute nodes or that are associated with the given cluster of compute nodes by compute nodes of other clusters in the distributed computing system (e.g., using an instance metadata tag and/or a storage system prefix); and/or restricting access to application programming interfaces of the distributed computing service by the given cluster of compute nodes (e.g., using an identity and access manager).Type: GrantFiled: May 23, 2014Date of Patent: May 19, 2020Assignee: Amazon Technologies, Inc.Inventors: Rejith George Joseph, Tin-Yu Lee, Scott Michael Le Grand, Saurabh Dileep Baji

Patent number: 10379956Abstract: Data files in a distributed system sometimes becomes unavailable. A method for fault tolerance without data loss in a distributed file system includes allocating data nodes of the distributed file system among a plurality of compute groups, replicating a data file among a subset of the plurality of the compute groups such that the data file is located in at least two compute zones, wherein the first compute zone is isolated from the second compute zone, monitoring the accessibility of the data files, and causing a distributed task requiring data in the data file to be executed by a compute instance in the subset of the plurality of the compute groups. Upon detecting a failure in the accessibility of a data node with the data file, the task management node may redistribute the distributed task among other compute instances with access to any replica of the data file.Type: GrantFiled: May 15, 2017Date of Patent: August 13, 2019Assignee: Amazon Technologies, Inc.Inventors: Mohana Sudhan Gandhi, Rejith George Joseph, Bandish N.

Patent number: 10148736Abstract: A client may submit a job to a service provider that processes a large data set and that employs a message passing interface (MPI) to coordinate the collective execution of the job on multiple compute nodes. The framework may create a MapReduce cluster (e.g., within a VPC) and may generate a single key pair for the cluster, which may be downloaded by nodes in the cluster and used to establish secure node-to-node communication channels for MPI messaging. A single node may be assigned as a mapper process and may launch the MPI job, which may fork its commands to other nodes in the cluster (e.g., nodes identified in a hostfile associated with the MPI job), according to the MPI interface. A rankfile may be used to synchronize the MPI job and another MPI process used to download portions of the data set to respective nodes in the cluster.Type: GrantFiled: May 19, 2014Date of Patent: December 4, 2018Assignee: Amazon Technologies, Inc.Inventors: Tin-Yu Lee, Rejith George Joseph, Scott Michael Le Grand, Saurabh Dileep Baji, Peter Sirota

Patent number: 10133646Abstract: A method for providing fault tolerance in a distributed file system of a service provider may include launching at least one data storage node on at least a first virtual machine instance (VMI) running on one or more servers of the service provider and storing file data. At least one data management node may be launched on at least a second VMI running on the one or more servers of the service provider. The at least second VMI may be associated with a dedicated IP address and the at least one data management node may store metadata information associated with the file data in a network storage attached to the at least second VMI. Upon detecting a failure of the at least second VMI, the at least one data management node may be re-launched on at least a third VMI running on the one or more servers.Type: GrantFiled: March 24, 2017Date of Patent: November 20, 2018Assignee: Amazon Technologies, Inc.Inventors: Rejith George Joseph, Tin-Yu Lee, Bandish N.
