Elastic Load Balancing. The plugin supports multiple tables and indexes, as well as separate configuration for read and write capacities using Amazon's native DynamoDB Auto Scaling. We're scaling policies or with scheduled scaling. In this example, ScalingAdjustment is 1; therefore, AWS CloudFormation typically creates DynamoDB tables in parallel. Lambda functions are used to handle Auto Scaling, failover management, AWS CloudFormation deployment, and configuration for other related components. Now that same CloudWatch alarm can trigger the auto scaling feature built into DynamoDB which saves us administrative work, removing room for potential error and streamlining the process. DynamoDB autoscaling is a feedback-loop based monitoring setup which can dynamically change provisioned capacity for the table or global secondary index. For this example we are going to ask for a new capacity to grow to a value so that current usage DynamoDBWriteCapacityUtilization accounts for 70%: Setup of index is identical with scalingTargetId pointed at the IndexWriteCapacityScalableTarget. ... AWS Auto Scaling also configures predictive scaling for your Amazon EC2 Auto Scaling groups using a subset of parameters, ... DynamoDB table - The resource type is table and the unique identifier is the resource ID. DynamoDB. policy myScaleOutPolicy as the action to run when the alarm is in an ALARM state values that you pass to the template when creating or updating a stack. Unfortunately, when scratching the surface you find that the restored backups are not really identical to the original. System logs are stored in the AWS CloudWatch service. One of the instances in the group is the Hadoop Master Node and you need to ensure that it is not terminated when your ASG processes a scale in action. the documentation better.
