AWS Lambda
OverviewIntroduced βeta in Nov 2014, stable version by end of 2015.
Leader in developer uptake, back-end services and eco-system.
Language choices: Node.js (JS), Python, Java 8, C#, VB/F#?
(CSAR project)
Cost: Free tier: 1 mn req/mth, then $0.00001667/GBy-sec details
Strengths: Created the space, enormous ecosystem, Cloud9 IDE?
Weaknesses: A little slow, limited languages, lock-in
AWS Lambda: in more detail
AWS Lambda: Use Case - Smart News
AWS Lambda: Demo - GUI
But all that clicking around is hard work !!
- let's use a CLI or API
AWS Lambda: Demo - CLI (az)
Serverless Python !!
AWS Lambda: Demo - Chalice Python Wrapper
But we need open Serverless for open Cloud
CNCF Serverless WG to
-
Provide clarity on the topic:
- * Define common terminology
- * Define the scope of the space
- * Identify common use cases and patterns
- * Identify relation to PaaS and container orchestration
-
Identify potential next steps for the community:
- * Identify areas for harmonization or interop work
- Create a whitepaper on Serverless.
