Synchronous vs Asynchronous APIs: What Actually Scales
In this short video, we break down:
• What synchronous APIs really do
• Why asynchronous APIs exist
• Where queues and background workers fit
• When async is the right architectural choice
To make this concrete, we demonstrate the pattern using a real example:
a fully asynchronous SSH key generation API built using cloud-native services.
The example is intentionally simple:
• A client submits a request
• The API returns a ticket
• Background workers process the request
• The client retrieves the result later
This pattern is implemented end-to-end on:
• AWS - • Build a Serverless Keygen API on AWS with ...
• Azure - • Serverless SSH Key Generation on Azure (Se...
• Google Cloud - • Build a Serverless SSH KeyGen API on GCP |...
If you’ve ever wondered why async APIs matter — or how they actually work in practice —
this video is the starting point.
