Serverless Golang

Not LISP

AWS Lambda function

• Code run in containers
• Supports NodeJS and Python currently
• Limited execution time and storage
• Great for event processing

Apex - a tool to run go code on Lambda

• Introducing TJ Holowaychuk
• Build, deploy, and manage AWS Lambda functions with ease (with Go support!)

Event triggers

• Inputs: Events - scheduled events === cron
• Outputs: AWS SDK for Go

Competition: Serverless Framework

functions:
  zencoderclip:
    handler: clip.handler
    events:
      - http:
         path: clip
         method: post
         authorizer: arn:aws:lambda:ap-southeast-1:024749985657:function:zencoder-basicauth

• Can run binaries
• serverless.yml offers an easier setup with events
• `invoke local`
• How is this different to Apex?

Demo

• AWS console
• A simple Apex example leveraging templates

Caveats

• /dev/stderr for logging
• Testing offline can be a bit painful
• Authorisation seems darn tricky
• Multi-tenant seems even trickier
• AWS is a learning a curve for your team

To conclude

Staying productive

Prepare a talk on AWS Lambda
in order to share what I have learnt using it
because I want to become better at using technology

Take aways:

1. You can use AWS Lambda with Go
2. An example where you can leverage Golang templates
3. Give serverless a try!
