Amazon Si...
70/100
SQS excels for teams already embedded in the AWS ecosystem seeking serverless, maintenance-free message queues without infrastructure overhead. Platform engineering teams adopt it rapidly for decoupling microservices, but data engineers requiring complex stream processing, geo-replication, or Kafka compatibility will face significant architectural constraints. The service eliminates cluster management but offers only basic queuing semantics compared to unified streaming platforms.
Nsq
70/100
NSQ suits small engineering teams prioritizing operational simplicity over complex messaging guarantees. Platform engineering teams managing multi-tenant architectures will struggle without namespace isolation and geo-replication capabilities. Its single-binary deployment eliminates the ZooKeeper and BookKeeper operational burden required by Pulsar.
Adoption RiskExpected friction, training effort, and behavior change needed to move teams onto the alternative.
