Serverless Demo Basic Demo -> Production Grade
AWS Toolkit for Visual Studio
AWS SAM
• CLI tool for local development,
deployment, debugging, testing,
deploying, and monitoring
• Supports API Gateway “proxy-style” and
Lambda service API testing
• Docker Lambda and DynamoDB images
to mimic AWS environment including
timeout, memory limits, runtime
• Can tail production logs from
CloudWatch logs
• Can help build in native dependencies

Serverless Demo Basic Demo -> Production Grade
Tells AWS CloudFormation this is a
SAM template it needs to “transform”
Lambda configuration. Timeout = 30
seconds
Creates a AWS Lambda function with
referenced IAM policy, runtime, code,
and handler as defined
Creates an API Gateway and takes
care of all mapping/permissions
necessary
Creates a Amazon DynamoDB table

Real Time Observability, Telemetry,
and Monitoring
• Setup tracing tools to visualize and track
the real-time performance of services
• Integrate tools for real-time high-
resolution metrics to spot outliers quickly.
Down to the exact invocation
• Use custom labels for intelligent logging,
filtering and advance searching
• Setup auto-triaged alerts based on
custom triggers
End-to-end App Automation
• Leverage deployment templates &
frameworks with built-in best practices to
create functions, APIs, databases, and
event source mappings
• Automate backups and disaster recovery
mechanisms through intelligent routing
• CI/CD toolchain integration
A large event driven serverless application may have 100s of services firing off millions of events per minute. NoOps is critical in
ensuring application sustainability during test, deploy, log and monitor
Automate Security
• Setup rules engine for cloud security, cost
optimization, and governance
• Automate security guardrails ensuring
real time enforcement of security policies
(e.g. encryption, access requirements)
Local Debugging And Testing
• Develop and test locally in prod-like
environment
• Tighten development loop by finding
issues locally before deploying to the
cloud.
