ABOUT
SERVERS
WHAT IS SERVERLESS?
"SERVERLESS APPLICATIONS DON'T REQUIRE YOU TO PROVISION, SCALE, AND MANAGE ANY SERVERS.
Â
YOU CAN BUILD THEM FOR ANY TYPE OF APPLICATION AND EVERYTHING REQUIRED TO RUN AND SCALE YOUR APPLICATION WITH HIGH AVAILABILITY IS HANDLED FOR YOU."
https://aws.amazon.com/serverless/
Â
Serverless is a new paradigm of computing that abstracts away the complexity associated with managing servers for mobile and API backends, Â data processing jobs, databases, and more.
https://cloud.google.com/serverless/
"A Serverless solution is one that costs you nothing to run if nobody is using it*"
*(EXCLUDING DATA STORAGE)
- Paul Johnston
