- CX-Ray integration needs to be enabled with CodeDeploy.
158The X-Ray daemon is running on my EC2, and my application manages to send X-Ray traces from my computer, but it still doesn't work from my EC2 instance. What's wrong?

172You have a Kinesis stream usually receiving 5Mb/s of data and sending out 8Mb/s of data. You have provisioned 6 shards. Some days, your traffic spikes up to 2 times and you get a throughput exception. You should:
- AEnable Kinesis replication.
- BAdd more shards.
- CUse SQS as a buffer to Kinesis.
173You are sending a clickstream for your users navigating your website, all the way to Kinesis. It seems that the users data is not ordered in Kinesis, and the data for one individual user is spread across many shards. How do you fix that problem?
- AThere are too many shards, you should only use one shard.
- BYou should use a partition key that represents the identity of the user.
- CYou shouldn't use multiple containers, only one and it should re-order data.
