Abstract: Systems and methods are described for providing logging functionalities to code executing in an on-demand code execution system while minimizing the need to define such functionalities within the code. A logging endpoint is provided that can be called by an execution of code and passed information for logging. The logging endpoint can enrich the information with additional information, such as information regarding a state of an execution environment for the code (which additional information may not be accessible to the execution of code itself). The logging endpoint can then facilitate storage of the enriched logging information, such as by handling authentication to a storage endpoint. Thus, users of the system may author code that provides robust logging functionalities while minimizing the implementation of such functionalities within the authored code.

Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. In order to increase the speed of provisioning, a data replication may be provision with less than the total number of nodes to be included in the group. Once an initial set of nodes have been provisioned and are implementing a consensus protocol, the data replication group may begin to receive traffic. Furthermore, new nodes may be added to the group until the total number of nodes for the group has been reached.

Abstract: Systems and methods are described for enabling cross-environment application of tracing information for code, such as code executed within an on-demand (or “serverless”) code execution system. Various optimizations exist that allow execution of code to proceed faster or more efficiently over time, by collecting tracing information regarding the execution and using that tracing information to guide compilation of the code. These optimizations are typically designed for long-lived environments. However, executions within an on-demand code execution system often occur in short-lived environments, reducing or eliminating any gains from these optimizations. To address this issue, tracing information can be maintained across multiple environments on the system, allowing subsequent executions to be optimized based on tracing information of prior executions in other environments.

Abstract: Systems and methods are described for adjusting a number of concurrent code executions allowed to be performed for a given user on an on-demand code execution environment or other distributed code execution environments. Such environments utilize pre-initialized virtual machine instances to enable execution of user-specified code in a rapid manner, without delays typically caused by initialization of the virtual machine instances. However, to improve utilization of computing resources, such environments may temporarily restrict the number of concurrent code executions performed on behalf of the given user to a number less than the maximum number of concurrent code executions allowed for the given user. Such environments may adjust the temporary restriction on the number of concurrent code executions based on the number of incoming code execution requests associated with the given user.

Abstract: A data storage system includes multiple head nodes and data storage sleds. The data storage sleds include multiple mass storage devices and a sled controller. Respective ones of the head nodes are configured to obtain credentials for accessing particular portions of the mass storage devices of the data storage sleds. A sled controller of a data storage sled determines whether a head node attempting to perform a write on a mass storage device of a data storage sled that includes the sled controller is presenting with the write request a valid credential for accessing the mass storage devices of the data storage sled. If the credentials are valid, the sled controller causes the write to be performed and if the credentials are invalid, the sled controller returns a message to the head node indicating that it has been fenced off from the mass storage device.

Abstract: Burst throttling methods may be used to manage computing resources of a data storage service. Tokens may represent I/O operations executed by a customer of the data storage service. A first token bucket may contain a set of tokens representing the overall I/O operation capacity of the data storage service. Additionally, a second token bucket may contain a set of tokens for a given logical volume maintained by the data storage service. When I/O requests are received tokens may be charged the first token bucket and the second token bucket. Furthermore, if there is sufficient capacity, the data storage service may charge a reduced number of tokens to the third token bucket.

Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. In order to increase the speed of provisioning, a pool of data replication groups may be maintained. When a request is received a data replication group may be selected from the pool, removed from the pool, and associated with the request. Furthermore, a replacement data replication group may be provisioned and added to the pool.

Abstract: Methods, systems, and computer-readable media for distributed transactions across multiple consensus groups are disclosed. A distributed transaction system comprises a proposer and a plurality of consensus groups, including a first consensus group comprising a first plurality of members and a second consensus group comprising a second plurality of members. The proposer proposes a transaction to at least a portion of the first consensus group and at least a portion of the second consensus group. A majority of the members in the first consensus group agree to perform the transaction, where the transaction is selected from a plurality of proposed transactions involving the first consensus group. A majority of the members in the second consensus group also agree to perform the transaction. The members of the first and second consensus groups perform the transaction to update a plurality of stored replicas.

Abstract: A system for providing low-latency compute capacity is provided. The system may be configured to route incoming code execution requests based on user indications to use specific containers running on a plurality of virtual machine instances. The system may be configured to process a code execution request, identify, based on the user indication that a specific container previously used to handle a request of similar type is to be used for handling the code execution request, and cause the code execution request to be handled using the specific container.

Abstract: A distributed system may implement identifying correlated events in a distributed system according to operational metrics. A distributed system may collect large numbers of operational metrics from multiple different sources. Some operational metrics may be monitored, analyzing the operational metrics for correlation with other operational metrics. The monitored operational metrics may be manually selected, or identified according to anomalous events detected for the operational metrics. Based on the monitoring, a correlated event may be detected. A response for the correlated event may be determined and performed. In some embodiments, a notification of the correlated event may be sent. Corrective actions may be performed at the distributed system, in some embodiments.
