Serverless Applications on AWS

  1. 1. Serverless Apps on AWS Dean Bryen - Solutions Architect - AWS James Hall - Co-Founder - Parallax dean@amazon.com @deanbryen

  2. 2. What are your goals?
  3. 3. 3 Racing within a window of time
  4. 4. 4 Focus is on solving a problem
  5. 5. 5 Skills are in Development not Infrastructure
  6. 6. 6 Over-Engineering vs Re-Engineering
  7. 7. The Evolution of Architecture
  8. 8. 8 The Monolith
  9. 9. 9 Micro Services
  10. 10. 10 API Driven Development
  11. 11. The Evolution of Compute and Storage
  12. 12. 12 Physical Servers / Disks ->VM’s
  13. 13. 13 Containers
  14. 14. 14 Platform Level Services
  15. 15. My Application Challenge
  16. 16. Build a micro service based web application that….. Scales per request Requires no deployment effort Fault Tolerant Has a RESTful API interface with a Web client
  17. 17. The Catch NO Servers NO Monolithic App or Explicit Web Service NO Explicit code for scaling and fault tolerance And do it within 45 minutes…
  18. 18. What Services Could we use?
  19. 19. Static Assets in Amazon S3 Internet scale HTTP/S based object store Inerently Highly Available and Fault Tolerant Designed for 11 9’s of Durability Can host static websites Holds trillions of objects
  20. 20. Serverless micro services with AWS Lambda Event Driven Computing service Never pay for idle Scales per request Supports Node.js, python and Java (or other JVM based languages) Event triggers from other AWS Services 23 different ‘Power Levels’ of AWS Lambda
  21. 21. A RESTful API with Amazon API Gateway Host multiple versions and stages of your API Create and distribute API Keys to your developers Throttle and Monitor API Calls Cache Responses Transform Data Generate SDK’s (Including Swagger Support)
 Interact directly with AWS Lambda
  22. 22. A NoSQL Data Store with Amazon DynamoDB Managed noSQL Data Store Can be either a Document or Key/Value store Simply provision read and write throughput Enables you to focuss on your data DynamoDB streams enables you to take actions on events Inherently Highly Available and Fault Tolerant
  23. 23. Putting it all together
  24. 24. The Service Itself Static Site in S3 www.servicecheck.com Web Client API Gateway
 /serviceCheck Lambda
 serviceLogger Lambda
 serviceCheck DynamoDB
  25. 25. Serverless Framework - Previously JAWS
  26. 26. It’s more cost effective
  27. 27. Demo
  28. 28. Some other serverless patterns
  29. 29. Serverless Real Time Clickstream Raw data pushed to S3 Amazon Redshift Amazon Kinesis Amazon Kinesis AWS Lambda
  30. 30. Serverless DAM Architecture users Ingest Bucket CloudFormation Template DynamoDB Cognito Lambda MetaData Extract Asset Bucket Index Logs Bucket Static Site Elastic Transcoder IAM ElasticSearch API$ Gateway$ Lambda App Logic
  31. 31. Serverless Chat Application Internet Activity Indicator Chat Service Activity Messages Search Service DynamoDB Streams Elasticsearch Service S3 Web Hosting Twilio Slack Chat API Gateway IoT Device IoT Processing Website AWS IoT or Amazon SNS
  32. 32. One Column parall.ax
 01133 226477 Subtitle Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has a the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. Here is an example: - Bullet Point one - Bullet Point one - Bullet Point one It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. @parallax
