Challenge

Create a Spot Fleet Request

You will create a Spot Fleet request that contains the target capacity and launch specifications for the instances. You will also create a new key pair which will be used when creating the spot request.

Challenge

Configure CloudWatch Alarms for Spot Fleet

You will configure two CloudWatch alarms: ScaleOut and ScaleIn. These alarms will be used in later challenges for auto scaling and will provide information about CPU utilization for the instances.

Challenge

Set up a Target Tracking Scaling Policy for a Spot Fleet Request

You will set up a target tracking scaling policy for a spot fleet request. A Target tracking scaling policy will set metrics and a target value. The CloudWatch alarms will trigger the scaling policy which in turn will add or remove the resources depending on the target value and metrics.

Challenge

Set up a Step or Simple Scaling Policy for a Spot Fleet Request

You will set up a step or simple scaling policy. The CloudWatch alarm will trigger the scaling policy. When you create a step scaling policy, you must specify one of the following scaling adjustment types: Add, Remove, or Set to.

Challenge

Set up Scheduled Scaling for a Spot Fleet

You will set up a scheduled scaling policy for a spot fleet. You can define the schedule when a predefined action should take place using cron expressions.
