- Operational Efficiency
AWS manages all ongoing operations and underlying infrastructure needed to reliability run and scale message queuing. SQS lets you eliminate the complexity and administrative overhead associated with managing dedicated message-oriented middleware (MoM) and associated infrastructure. 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. With SQS, queues are dynamically created and scale automatically so you can build and grow applications quickly - and efficiently.
You can 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. Any component of a distributed application can store messages in an SQS queue. Multiple copies of every message is stored redundantly across multiple availability zones so that they are available whenever applications need them. Message delivery is at least once with standard queues, and exactly once with FIFO queues.
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. AWS KMS logs every use of your encryption keys to AWS CloudTrail to help meet your regulatory and compliance needs. Authentication mechanisms also ensure that messages stored in Amazon SQS message queues are secured against unauthorized access.
- Accelerate Application Development
Amazon SQS is deeply integrated with other AWS services to make easy to build more flexible and scalable applications. Integrations include compute services such as Amazon EC2, Amazon EC2 Container Service (Amazon ECS), and AWS Lambda, as well as with storage and database services such as Amazon Simple Storage Service (Amazon S3), Amazon RDS, and Amazon DynamoDB. Amazon SQS works with Amazon Simple Notification Service (SNS) to deliver a powerful messaging solution.
It's easy to get started with message queuing using Amazon SQS, simply select the console or SDK of your choice. You can quickly add SQS to your code using only four APIs: CreateQueue, SendMessage, ReceiveMessage, and DeleteMessage. The same API applies to both Standard Queues and FIFO Queues.
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. Costs are based on usage which provides significant cost saving versus the “always-on” model with self-managed messaging middleware.
