The Serverless Framework

Bringing order to AWS Lambda

Andrew Tomaka

What is Lambda?

• Someone else's computer
• Someone else's operating system
• Your code

But Why?

• Shared Responsibility Model
• Infinite automatic scaling
• Cost reduction
  • Taking it a step further!

What does it Look Like

exports.index = function(event, context, callback) {
  if (isBusinessTime(new Date())) {
    callback(null, {
      statusCode: '200',
      body: JSON.stringify({ message: "It's time for business" }),
      headers: { 'Content-Type': 'application/json' }
    })
  } else {
    callback(null, {
      statusCode: '200',
      body: JSON.stringify({ message: "It's party time" }),
      headers: { 'Content-Type': 'application/json' }
    })
  }
}

function isBusinessTime(now) {
  return now.getDay() < 4 && now.getHours() >= 9 && now.getHours() < 17
}

but IT's not without problems

• Debugging
• Deploying
• Tracing
• Freezing and Thawing

WE just need the right tools
