Want to try a question for yourself? A social gaming startup has its flagship application hosted on a fleet of EC2 servers running behind an Elastic Load Balancer. These servers are part of an Auto Scaling Group. 90% of the users start logging into the system at 6 pm every day and continue till midnight. The engineering team at the startup has observed that there is a significant performance lag during the initial hour from 6 pm to 7 pm. The application is able to function normally thereafter. As a solutions architect, which of the following steps would you recommend addressing the performance bottleneck during that initial hour of traffic spike? 1. Configure your Auto Scaling group by creating a scheduled action that kicks-off before 6 pm. This causes the scale-out to happen even before peak traffic kicks in at 6 pm 2. Configure your Auto Scaling group by creating a lifecycle hook that kicks-off before 6 pm. This causes the scale-out to happen even before peak traffic kicks in at 6 pm. 3. Configure your Auto Scaling group by creating a target tracking policy. This causes the scale-out to happen even before peak traffic kicks in at 6 pm. 4. Configure your Auto Scaling group by creating a step scaling policy. This causes the scale-out to happen even before peak traffic kicks in at 6 pm. Correct: 1. The scheduled action tells Amazon EC2 Auto Scaling group to perform a scaling action at specified times. To create a scheduled scaling action, you specify the start time when the scaling action should take effect, and the new minimum, maximum, and desired sizes for the scaling action. The engineering team can create a daily scheduled action to kick-off before 6pm and hence this is the correct option. Auto Scaling group lifecycle hooks enable you to perform custom actions as the Auto Scaling group launches or terminates instances. For example, you could install or configure software on newly launched instances, or download log files from an instance before it terminates. Lifecycle hooks are not the correct choice for this use-case. With target tracking scaling policies, you choose a scaling metric and set a target value. Application Auto Scaling creates and manages the CloudWatch alarms that trigger the scaling policy and calculates the scaling adjustment based on the metric and the target value. With step scaling, you choose scaling metrics and threshold values for the CloudWatch alarms that trigger the scaling process as well as define how your scalable target should be scaled when a threshold is in breach for a specified number of evaluation periods. Both the target tracking as well as step scaling policies entail a lag wherein the instances will be provisioned only when the underlying CloudWatch alarms go off. Therefore we would still see performance lag during some part of the initial hour.
