SRE and DevOps share similar foundational principles;
SRE could be seen as a refined implementation of DevOps,
although SRE existed before the coinage of the term DevOps.

SRE contains ownership, oversight and responsibilities that differ from DevOps.

pushgateway clients (eg: lambda functions) push to api-gateway.

api gateway invokes a lambda "receiver" function which
- reads pushgateway event, and writes that event data to SNS

(decoupled event queue is implemented via SNS)

a lambda reader that triggers based on SNS queue depth
- writes SNS events to dynamodb (TTL optional)
