Apex vs Cloud Functions for Firebase: What are the differences?
What is Apex? Serverless Architecture with AWS Lambda. Apex is a small tool for deploying and managing AWS Lambda functions. With shims for languages not yet supported by Lambda, you can use Golang out of the box.
What is Cloud Functions for Firebase? Run your mobile backend code without managing servers. Cloud Functions for Firebase lets you create functions that are triggered by Firebase products, such as changes to data in the Realtime Database, uploads to Cloud Storage, new user sign ups via Authentication, and conversion events in Analytics.
Apex and Cloud Functions for Firebase belong to "Serverless / Task Processing" category of the tech stack.
