As aws-sdk provide API to create a Queue (Support both standard and FIFO queue).

• Create a standard queue.
• Create a FIFO queue.
• Customize important queue attributes:

DelaySeconds - The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 seconds (15 minutes). Default: 0.

MessageRetentionPeriod - The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 345,600 (4 days).

ReceiveMessageWaitTimeSeconds - The length of time, in seconds, for which a ReceiveMessage action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.

VisibilityTimeout - The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.

For FIFO queue, additional config should be set:

FifoQueue - Designates a queue as FIFO. Valid values: true, false. If you don't specify the FifoQueue attribute, Amazon SQS creates a standard queue. You can provide this attribute only during queue creation. You can't change it for an existing queue. When you set this attribute, you must also provide the MessageGroupId for your messages explicitly.
For more information, see FIFO Queue Logic in the Amazon Simple Queue Service Developer Guide.

ContentBasedDeduplication - Enables content-based deduplication. Valid values: true, false. For more information, see Exactly-Once Processing in the Amazon Simple Queue Service Developer Guide.
Every message must have a unique MessageDeduplicationId,
