  2. EVENT DRIVEN SYSTEM Service A F1 F2 F3 Service C

    F1 F2 Service B F1 Service E F1 F2 F3 Service F F1 F2 F3 Service D F1 F2 F3 F4 F5 S3 Kinesis DynamoDB Api Gateway
  3. THE SERVERLESS TEAM ▸ Least Amount of Control ▸ Least

    Amount of Responsibility ▸ Complete Automation ▸ Gradual Escalation of Control and Responsibility ▸ Build for Replacement
  4. HEAVY LIFTING IS DONE IN SERVICES ▸ Scheduling of Tasks

    ▸ Scaling of System ▸ Collecting of Log Data ▸ Authentication between Services ▸ Storing and managing data storage ▸ Provisioning and scaling Queue infrastructure ▸ …
  5. PAST SERVER SERVER SERVER SERVER SERVER SERVER SERVER SERVER SERVER

    SERVER SERVER SERVER Application cluster Database cluster Data and ETL Pipeline
  6. PAST VS PRESENT Past Present Features ‣ Replication ‣ Scalability

    ‣ … Usability Accessibility Best Practices
  7. MAKE IT EASY TO COMBINE SERVICES Service A F1 F2

    F3 Service C F1 F2 Service B F1 Service E F1 F2 F3 Service F F1 F2 F3 Service D F1 F2 F3 F4 F5 S3 Kinesis DynamoDB Api Gateway
  8. BAD TOOLS WILL PUSH US AWAY FROM SERVICES ▸ Many

    examples in AWS from great services that aren’t used enough ▸ CloudFormation ▸ IAM ▸ CloudWatch Metrics, Logs and Alerts ▸ Custom Resources ▸ AWS Config
  9. HORRIBLE CLI TOOLING FROM AWS ▸ Hard to learn and

    hard to read configuration ▸ No built-in modularity for one stack making config files huge ▸ There is no built-in command to deploy a stack, wait for it to be deployed and get the CF events as cli output
  10. ALL TOOLS SHOULD WORK TOWARDS CLOUDFORMATION ▸ Standard Endpoint allows

    us to swap out tools ▸ Not possible with other tools like Terraform as state is stored separately
  11. ALL TOOLS SHOULD WORK TOWARDS CLOUDFORMATION ▸ Standard Endpoint allows

    us to swap out tools ▸ Not possible with other tools like Terraform as state is stored separately ▸ Easier to support standards
  12. ALL TOOLS SHOULD WORK TOWARDS CLOUDFORMATION ▸ Standard Endpoint allows

    us to swap out tools ▸ Not possible with other tools like Terraform as state is stored separately ▸ Easier to support standards ▸ This also makes sure we’re building better low level tools with better UX
  13. SIMPLE TOOLS TO MAKE CF MORE USEFUL ▸ Awsie (https://github.com/flomotlik/awsie)

    awsie example-stack s3 ls s3://cf:DeploymentBucket: --region us-west-1 aws s3 ls s3://formica-example-stack-deploymentbucket-1jjzisylxreh9 --region us-west-1
 awsie example-stack —command “echo //cf:DeploymentBucket:” --region us-west-1 
 echo s3://formica-example-stack-deploymentbucket-1jjzisylxreh9
  14. STOP BUILDING ABSTRACTIONS I need this small thing Hmm it

    could also do this Lets introduce this small abstraction to make it applicable here and here Wow this got really complex, new tool it is
  15. PAST SERVER SERVER SERVER SERVER SERVER SERVER SERVER SERVER SERVER

    SERVER SERVER SERVER Application cluster Database cluster Data and Background Pipeline
  16. THE POWER IS IN COMBINING SERVICES, SO DON'T HIDE MORE

    HERE Service A F1 F2 F3 Service C F1 F2 Service B F1 Service E F1 F2 F3 Service F F1 F2 F3 Service D F1 F2 F3 F4 F5 S3 Kinesis DynamoDB Api Gateway
  17. PROBLEMS WITH MULTI-PROVIDER TOOLING ▸ Always gets dragged down to

    lowest common denominator ▸ In a Serverless infrastructure you’re not going to move Everything between providers ▸ Small surface area per provider ▸ You want to get all you can out of that provider so you need specialised tooling
  18. MY JOURNEY TO BUILD FORMICA ▸ https://github.com/flomotlik/formica ▸ Wanted to

    build and play with more AWS services so I needed a good CloudFormation tool ▸ Looked around at existing tools (Sceptre, Stacker, AWLess, Serverless, Gordon, Condensation, …) but all define their own abstractions ▸ Stack environments ▸ Dependencies between stacks ▸ Stack naming, ▸ Language to create the stack ▸ … ▸ So of course I built it using Troposphere so I could have nice python templates and added my own abstraction layer
  19. DOESN’T MEAN WE CAN’T IMPROVE CF SYNTAX ▸ Serverless/Gordon/Zappa are

    great for setting up an API Gateway with Lambdas ▸ We could have other tools as preprocessors for specific things ▸ Simple tool to translate HTTP endpoint definition to CF ▸ Tool to create CF templates for CloudWatch Alerts and Metrics
  20. SUITE OF SMALL FOCUSED TOOLS ▸ Built: ▸ Formica -

    Deploying CloudFormation templates ▸ AWSIE - Dynamically use CF ids in your shell commands ▸ Ideas: ▸ Orgonaut: Org/Account management and running commands against each command or group ▸ Auditor: Auditing and reporting setup with AWS Config and Cloudtrail across accounts ▸ Pipes: CI/CD setup through CodePipeline/CodeBuild ▸ Watchdog: CloudWatch config tool to make Monitoring and Alerts easier to configure ▸ Work together as a community to highlight those tools and define a best-practice suite

  22. CONCLUSIONS ▸ Composition and Accessibility, not Features and Abstractions ▸

    Build and use small tools that do one thing well ▸ Compose larger systems out of several smaller tools ▸ Go check out Make, its reasonably good ▸ Join the Serverless Slack (Serverless-Forum, https://wt-serverless- seattle.run.webtask.io/serverless-forum-signup?webtask_no_cache=1) T W I T T E R : @ F L O M O T L I K W E B S I T E : F L O M O T L I K .
