• 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!

• 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

But wait…
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

Next steps
• Explore the AWS SAM specification on GitHub
• Visit the Lambda console, download a blueprint, and get
started with AWS SAM
• Send us your questions, comments, and feedback on
the AWS Lambda Forums.
Thank you!
Remember to complete
