• What if my serverless application consists of dozens or

hundreds of AWS resources?

• What if I have a large dev team?

• Use AWS SAM (powered by CloudFormation)

AWS CloudFormation

• Provision and manage a collection of related AWS

resources.

• Your application = CloudFormation stack

• Input .yaml file and output provisioned AWS resources

AWS Serverless Application Model (SAM)

• CloudFormation extension optimized for serverless

• New serverless resource types: functions, APIs, and

tables

• Supports anything CloudFormation supports

• Open specification (Apache 2.0)

NEW!

• Automated deployment (CI/CD)

• Tracing & troubleshooting

AWS commands – Package & Deploy

• Package

• Creates a deployment package (.zip file)

• Uploads deployment package to an Amazon S3 bucket

• Adds a CodeUri property with S3 URI

• Deploy

• Calls CloudFormation ‘CreateChangeSet’ API

• Calls CloudFormation ‘ExecuteChangeSet’ API

AWS CodePipeline

• Continuous delivery service for fast and reliable

application updates

• Model and visualize your software release process

• Builds, tests and deploys your code with every git push

• Integrates with multiple AWS services and 3rd party tools

AWS CodeBuild

• Build and test code in the cloud

• Automatically scales to meet your build volume

• Curated build environments that include runtime and

testing tools for Python, Java, and Node.js

Serverless CI/CD

Serverless ALM checklist

• Configuration & management

• Manual deployment

• Automated deployment (CI/CD)

• Tracing & troubleshooting

Debugging and monitoring

CloudWatch Metrics

• Default (free) metrics:

• Invocations

• Duration

• Throttles

• Errors

• Create custom metrics for

health and status tracking

Metrics and logs

CloudWatch Logs

• Every invocation generates

START, END and REPORT

entries to CW Logs

• Emit your own log entries

• Use 3rd party tools for

aggregation and visualization

X-Ray + Lambda

• Collects data about requests that your application serves

• Provides diagnostic tools

• Visibility into the Lambda service

• Breakdown of your function’s performance

COMING

Service map COMING

SOON!

Trace view COMING

SOON!

X-Ray + Lambda

• Service map – identify where your errors or latency

problems are coming from

• Trace view – zoom in to determine the root cause
