Spark’s recovery process helps it recover random executor and node failures that can occur in any cloud environment. However, the recovery process begins only after the node has already failed and Spark gets aFetchFailedExceptionwhile trying to fetch shuffle blocks. This causes some of the i...
The solution that we propose is based on a tool named SmartDepl that, when integrated in the ABS model of the Fredhopper Cloud Services, enables the modeling of automatic upscaling or downscaling. When the decision to scale up or down is made, SmartDepl indicates how to automatically evolve...
Figure 8: autoscaling EC2 instances in AWS. AWS also supportspredictive scaling, which uses machine learning to anticipate traffic patterns and manage instance counts accordingly. The goal is to intelligently scale cloud resources without requiring a cloud administrator to configure autoscaling rules. Ma...
