This document discusses serverless application lifecycle management (ALM) techniques. It provides an overview of common serverless use cases like web applications and data processing. It then outlines a serverless ALM checklist including configuration/management, deployment methods, and tracing/troubleshooting. Specific AWS services for packaging, deploying, automating deployment, and monitoring serverless applications like AWS Lambda, AWS Serverless Application Model (SAM), AWS CodePipeline, and AWS CloudWatch are also discussed. The document concludes with a call for feedback and further exploration of serverless ALM best practices.

• 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)

7. AWS CloudFormation
• Provision and manage a collection of related AWS
resources.
• Your application = CloudFormation stack
• Input .yaml file and output provisioned AWS resources

8. 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!

11. Serverless ALM checklist
• Configuration & management
• Manual deployment
• Automated deployment (CI/CD)
• Tracing & troubleshooting

12. 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
NEW!

16. 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

• Throttles
• Errors
• Create custom metrics for
health and status tracking
Metrics and logs
CloudWatch Logs
• Every invocation generates
START, END and REPORT

• Collects data about requests that your application serves
• Provides diagnostic tools
• Visibility into the Lambda service
• Breakdown of your function’s performance
COMING
SOON!

29. Service map COMING
SOON!

30. Trace view COMING
SOON!

31. X-Ray + Lambda
• Service map – identify where your errors or latency
problems are coming from
• Trace view – zoom in to determine the root cause

33. 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.
