另一件事:Kinesis可以触发Lambda，而SQS不能。因此，对于SQS，您要么必须提供一个EC2实例来处理SQS消息(并在失败时处理它)，要么必须有一个预定的Lambda(它不能扩大或缩小—每分钟只能得到一个)。

编辑:这个答案不再正确。自2018年6月起，SQS可以直接触发Lambda

https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html

对我来说，最大的优势是Kinesis是一个可重玩的队列，而SQS不是。因此，您可以有多个Kinesis的相同消息的消费者(或在不同时间的相同消费者)，而在SQS中，一旦消息被ack，它就从队列中消失了。 因此，SQS更适合工作者队列。

摘自AWS文档:

We recommend Amazon Kinesis Streams for use cases with requirements that are similar to the following: Routing related records to the same record processor (as in streaming MapReduce). For example, counting and aggregation are simpler when all records for a given key are routed to the same record processor. Ordering of records. For example, you want to transfer log data from the application host to the processing/archival host while maintaining the order of log statements. Ability for multiple applications to consume the same stream concurrently. For example, you have one application that updates a real-time dashboard and another that archives data to Amazon Redshift. You want both applications to consume data from the same stream concurrently and independently. Ability to consume records in the same order a few hours later. For example, you have a billing application and an audit application that runs a few hours behind the billing application. Because Amazon Kinesis Streams stores data for up to 7 days, you can run the audit application up to 7 days behind the billing application. We recommend Amazon SQS for use cases with requirements that are similar to the following: Messaging semantics (such as message-level ack/fail) and visibility timeout. For example, you have a queue of work items and want to track the successful completion of each item independently. Amazon SQS tracks the ack/fail, so the application does not have to maintain a persistent checkpoint/cursor. Amazon SQS will delete acked messages and redeliver failed messages after a configured visibility timeout. Individual message delay. For example, you have a job queue and need to schedule individual jobs with a delay. With Amazon SQS, you can configure individual messages to have a delay of up to 15 minutes. Dynamically increasing concurrency/throughput at read time. For example, you have a work queue and want to add more readers until the backlog is cleared. With Amazon Kinesis Streams, you can scale up to a sufficient number of shards (note, however, that you'll need to provision enough shards ahead of time). Leveraging Amazon SQS’s ability to scale transparently. For example, you buffer requests and the load changes as a result of occasional load spikes or the natural growth of your business. Because each buffered request can be processed independently, Amazon SQS can scale transparently to handle the load without any provisioning instructions from you.
