What is a queue in a customer service?
Customer requests are organized into queues. Queues let you quickly view, triage and assign requests as they come in. They also provide high-level information on an issue; usually a summary, status, and customer name. Queues are normally sorted by a Service Level Agreement or goal for your team's service interactions. A clock on the issue indicates the time until your team's next target is due.
What is queue sorted by?
Queues are normally sorted by a Service Level Agreement or goal for your team's service interactions. A clock on the issue indicates the time until your team's next target is due. You can use the preconfigured queues in your service project or you can create your own custom queues.
How many queues can you create in a project?
You can create up to 50 queues per project. If you reach the limit, see if you can combine queues, or remove ones you don't use anymore.

Firstly, Standard queues. This provides maximum throughput, best-effort ordering, and at least one delivery.
How many queue types does Amazon SQS have?
Amazon SQS provides two queue types for different application requirements:
How many messages can a FIFO queue handle?
FIFO queues have the support of up to 300 messages per second. However, when there is batching of 10 messages per operation then, FIFO queues can support up to 3,000 messages per second. Further, if there is a need for higher throughput, you can enable high throughput mode for FIFO on the Amazon SQS console, which will support up to 30,000 messages per second with batching. In this, the message is delivered once and it remains accessible until a consumer process and deletes it. The receiving order of messages sent and received is First-In-First-Out.

Benefits of using Amazon SQS
Security – You control who can send messages to and receive messages from an Amazon SQS queue.
Differences between Amazon SQS, Amazon MQ, and Amazon SNS
Amazon SQS and Amazon SNS are queue and topic services that are highly scalable, simple to use, and don't require you to set up message brokers. We recommend these services for new applications that can benefit from nearly unlimited scalability and simple APIs.

Fully managed message queues for microservices, distributed systems, and serverless applications
Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message-oriented middleware, and empowers developers to focus on differentiating work.
Eliminate administrative overhead
AWS manages all ongoing operations and underlying infrastructure needed to provide a highly available and scalable message queuing service. With SQS, there is no upfront cost, no need to acquire, install, and configure messaging software, and no time-consuming build-out and maintenance of supporting infrastructure.
Reliably deliver messages
Use Amazon SQS to transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be available. SQS lets you decouple application components so that they run and fail independently, increasing the overall fault tolerance of the system.
Keep sensitive data secure
You can use Amazon SQS to exchange sensitive data between applications using server-side encryption (SSE) to encrypt each message body. Amazon SQS SSE integration with AWS Key Management Service (KMS) allows you to centrally manage the keys that protect SQS messages along with keys that protect your other AWS resources.
Scale elastically and cost-effectively
Amazon SQS leverages the AWS cloud to dynamically scale based on demand. SQS scales elastically with your application so you don’t have to worry about capacity planning and pre-provisioning. There is no limit to the number of messages per queue, and standard queues provide nearly unlimited throughput.
Case Management
Enable dynamic service case management with the service queue. This tool helps you deliver faster resolutions to your customers’ problems by automatically collecting incoming cases and assigning each a unique session code.
Automated Service Case Assignment
Save time assigning service requests across your team, so that the right person can get started on important tasks without delay.
Put someone on CC
The extension for a better workflow: with the possibility to put more users on CC, your team remains always up to date and servicecamp tickets are processed more efficiently.
