Abstract: Provided herein are systems and methods for resilience testing. A system includes at least one hardware processor coupled to a memory and configured to decode a workflow to obtain a workload specification and a failure experiment specification. A first set of containers is configured to execute one or more workloads on a testing node. The one or more workloads are defined by the workload specification. A second set of containers is configured to execute one or more failure experiments on the testing node. The one or more failure experiments are based on the failure experiment specification. Execution of the one or more failure experiments triggers an error condition on the testing node. A notification is generated based on at least one metric associated with execution of the one or more workloads and the one or more failure experiments.

Abstract: Provided herein are systems and methods for resilience testing. A system includes at least one hardware processor coupled to a memory and configured to decode a workflow to obtain a workload specification and a network experiment specification. A first set of containers is configured to execute one or more workloads on a testing node. The one or more workloads are defined by the workload specification. A second set of containers is configured to execute one or more network experiments on the testing node. The one or more network experiments are based on the network experiment specification. Execution of the one or more network experiments triggers an error condition on the testing node. A notification is generated based on at least one metric associated with execution of the one or more workloads and the one or more network experiments.

Abstract: Described herein are techniques for improving performance of a data system by profiling and executing background services based on task type profiles. Techniques described herein can break down background services into tasks and provide the ability to accurately size the tasks based on task types and provide recommendations for gateways for autoscaling and throttling computing resources accordingly.
