Why we do what we do?
2
Serverless is New Agile
Serverless Dev (gluing
other people’s APIs
and managed services)
We're obsessed by
creating business value
(meaningful MVPs,
products) and helping
Startups
We build bridges
between Serverless
Community (“Dev leg”),
and Front-end & Voice-
First folks (“UX leg”),
and empower UX
developers
Achieve agility NOT by
“sprinting” faster (like in
Scrum), but by working
smarter (by using
bigger building blocks
and less Ops)

www.seed.runSEED
Real-world Serverless apps
Dozens of services
Multiple Git repos
With many environments
Pull request based workflow

19.
www.seed.runSEED
Apps vs Services
App: collection of services
Service: has a serverless.yml

20.
www.seed.runSEED
Organizing services
Microservice architecture
Organized by business units
Split by the 200 resource limit

21.
www.seed.runSEED
Organizing repos
Repo for infrastructure
Repo with all APIs + Lambdas

22.
www.seed.runSEED
Multiple environments
Environments are cheap
Long lived vs ephemeral
Split by multiple AWS accounts

23.

Development workflow
1. Work in a new feature branch
2. Create a PR when ready
3. Review & merge PR to master
4. Promote to Production

25.
www.seed.runSEED
CI/CD in the
Serverless world

26.
www.seed.runSEED
Continuous Integration
Git push triggers build
Run linting & other checks
Run unit tests
Generate build artifacts

27.
www.seed.runSEED
Continuous
Deployment

28.
www.seed.runSEED
Deploying services
Dozens of services
Each takes a few mins
Deploy them concurrently

29.
www.seed.runSEED
Inter-service dependencies
CloudFormation exports
Order of deployments
Deploy in phases

30.
www.seed.runSEED
Review infrastructure changes
Infrastructure as code
Easy to make mistakes
Review change sets

31.
www.seed.runSEED
Ephemeral environments
Many short-lived environments
Branches + PRs environments
Auto setup & teardown

32.
www.seed.runSEED
Efficient deployments
Slow deployments
Most common complaint
Deploy only updated services
Check Git log & artifact hash

33.
www.seed.runSEED
CodeBuild +
CodePipeline

34.
www.seed.runSEED
CodeBuild
CI service
Serverless build containers
Like CircleCI and Travis CI

35.
www.seed.runSEED
CodePipeline
Manage pipelines
Create multiple steps
CodeBuild is one of the steps

36.
