With Amazon SQS version 2008-01-01, the maximum message size for both SOAP and Query requests is 8KB. If you need to send messages to the queue that are larger than 8 KB, AWS recommends that you split the information into separate messages. Alternatively, you could use Amazon S3 or Amazon SimpleDB to hold the information and include the pointer to that information in the Amazon SQS message. If you send a message that is larger than 8KB to the queue, you will receive a MessageTooLong error with HTTP code 400.

The stack is the core AWS OpsWorks component. It is basically a container for AWS resources – Amazon EC2 instances, Amazon RDS database instances, and so on – that have a common purpose and should be logically managed together. You define the stack's constituents by adding one or more layers. A layer represents a set of Amazon EC2 instances that serve a particular purpose, such as serving applications or hosting a database server. An instance represents a single computing resource, such as an Amazon EC2 instance.

This can be bit of a trick question. While Ansible Playbooks in this course are written in YAML, Ansible will accept plays, tasks and playbooks in JSON, as JSON a subset of YAML. However, the preferred and fully supported method is YAML.

CloudTrail records attempts to sign into the AWS Management Console, the AWS Discussion Forums and the AWS Support Center. Note, however, that CloudTrail does not record root sign-in failures.

The Docker daemon can listen for Docker Remote API requests via three different types of Socket: unix, tcp, and fd. By default, a unix domain socket (or IPC socket) is created at /var/run/docker.sock, requiring either root permission, or docker group membership. If you need to access the Docker daemon remotely, you need to enable the tcp Socket. Beware that the default setup provides unencrypted and un-authenticated direct access to the Docker daemon - and should be secured either using the built in HTTPS encrypted socket or by putting a secure web proxy in front of it.
