3. Why Serverless!
No server is easier to manage than no server.
Werner Vogels, CTO, Amazon.com
No Infrastructure Provisioning,
no management
Automatic Scaling
Pay for only what you
use
High Availability and Secure
Environment

4. Serverless Consumption and Cost Model
Data Center IaaS Containers Serverless
Buying the Servers
and managing them
manually
Leasing/Renting the
Office
Leasing the space for
a day or few days

13. Framework Selection
Serverless Application Model
http://bit.ly/serverless-aws-sam
From AWS
CloudFormation based Templates
Integrated with AWS services
CloudFormation knowledge req.
Serverless Framework
https://serverless.com
Premium + Open Source
Community Driven
Lots of Plugins
Easy to Start

15. serverless.yml
service:
name: simpleService
provider:
name: aws
runtime: nodejs10.x
functions:
helloWorld:
handler: handler.helloWorld
events:
- http:
path: hello-world
method: get
module.exports.helloWorld = (event,
context, callback) => {
const response = {
statusCode: 200,
headers: {
'Access-Control-Allow-Origin': '*',
},
body: JSON.stringify({
message: `Hello, World`
}),
};
callback(null, response);
};
handler.js

16. Monitoring and Logging
● Lambda, API Gateway Dashboard
● AWS X-Ray
● Correlation IDs (Request Ids)
● CloudWatch Logs
● Kinesis Data Streams
● ElasticSearch
● 3rd Party Tools like IOPipes, Datadog, etc

17. Lambda Runtime and Layers (reduce size and
complexities)
● In case you are using any binary dependencies on local, make
sure you use suitable dependencies when you deploy your
lambdas to AWS
● Another easy option is to use Layers and get away from
uploading dependencies every time
