AWS学习笔记（十六）：SQS, SNS & Kinesis

using SQS: queue model
using SNS: pub/sub model
using Kinesis: real-time streaming model

Amazon SQS – Standard Queue

• Oldest offering (over 10 years old)
• Fully managed service, used to decouple applications
• Attributes:
  • Unlimited throughput, unlimited number of messages in queue
  • Default retention of messages: 4 days, maximum of 14 days
  • Low latency (<10 ms on publish and receive)
  • Limitation of 256KB per message sent
• Can have duplicate messages (at least once delivery, occasionally)
• Can have out of order messages (best effort ordering)

Kinesis

• Kinesis Data Streams: capture, process, and store data streams
• Kinesis Data Firehose: load data streams into AWS data stores 以可靠方式将实时数据串流加载到数据湖、数据库和分析服务中
• Kinesis Data Analytics: analyze data streams with SQL or Apache Flink
