What size servers are right for
my budget?
How many servers do I need?
How many servers should I
budget for?
When should I decide to
scale out my servers?
How will I keep my server OS
patched?
How will new code be deployed
to my servers?
I need to administrate it.
How to stop paying for it when it
won’t be needed anymore…
No Server is Easier to ManageThan “No Server”
Werner Vogels, Amazon CTO
Lambda
=
Microservice without servers
Lambda function
Lambdafunction
var AWS = require(‘aws-sdk’);
var s3 = new AWS.S3();
exports.handler = function(event, context) {
var params = {
Bucket: ‘[input bucket name here]’
Key: ‘[insert keyname here]’
Body: ‘[object body]’
};
s3.putObject(params)
console.log(‘Object inserter’)
};

What’s going on with my FaaS?
Good monitoring system is base for every
good serverless application
• End-to-end tracing to and from lambda
functions, without changing your code
• AI powered problem detection
• Response times
• Failure rates
• Process metrics
• End-to-end visibility
