2. Navigate to the SQS section from the sidebar menu.
3. Click on Create New SQS.
4. Provide the necessary details such as Queue Name, Data Center Location, and Plan Type.
5. Click Create SQS to deploy your queue.

3. What are the benefits of using SQS?

Answer:

• Scalability: Automatically scales to handle any volume of messages.
• Reliability: Ensures messages are not lost and are delivered at least once.
• Flexibility: Supports both standard and FIFO (First-In-First-Out) queues.
• Integration: Easily integrates with other Utho Cloud services and third-party applications.

4. How is SQS billed?

Answer: SQS billing is based on the number of requests and the amount of data transferred. There may also be charges for additional features such as long polling or message retention. Please refer to the Utho Cloud pricing page for detailed pricing information.

5. What is the maximum message size allowed in SQS?

3. What is the visibility timeout in SQS?

Answer: The visibility timeout is the period during which a message is invisible to other consumers after a consumer retrieves it from the queue. If the message is not deleted or processed within this period, it becomes visible again for other consumers. This ensures that messages are processed at least once.

5. Save your settings.

5. How can I secure my SQS queues?

Answer:

• IAM Policies: Use IAM roles and policies to control access to your SQS queues.
• Queue Policies: Configure queue policies to specify who can perform actions on your queues.
• Encryption: Enable server-side encryption to protect your messages at rest.
• VPC Endpoints: Use VPC endpoints to securely access SQS from within your VPC without traversing the internet.

6. What are the differences between Standard and FIFO queues?

Answer:

• Standard Queues: Offer best-effort ordering and at-least-once delivery. They are suitable for scenarios where the order of messages is not critical.
• FIFO Queues: Guarantee the order of messages and exactly-once processing. They are suitable for scenarios where the order of operations and deduplication of messages are important.
