- 8. Introduction
- 9. What is Serverless ?
- 10. *aaS (... as a service)
- 11. BaaS (back-end as a service)
- 12. FaaS (function as a service)
- 13. What will we build? Serverless Cat Detector
- 14. Amazon Web Services ? S3 ? Lambda ? API Gateway ? DynamoDB ? Image Rekognition ? CloudWatch ? X-Ray
- 15. S3 is an object storage built to store and retrieve any amount of data from anywhere. S3 (Simple Storage Service)
- 16. Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running. Lambda
- 17. API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. API Gateway
- 18. DynamoDB DynamoDB is a NoSQL database service. It is a fully managed cloud database that supports both document and key-value store models.
- 19. Image Rekognition Rekognition makes it easy to add image and video analysis to your applications. Service can identify the objects, people, text, scenes, and activities, as well as detect any inappropriate content.
- 20. CloudWatch is a monitoring service for AWS cloud resources and the applications you run on AWS. CloudWatch
- 21. X-Ray helps developers analyze and debug production, distributed applications, such as those built using a microservices architecture. X-Ray

- 97. Serverless - Invoke Locally export SLS_DEBUG=* # to have detail logging export AWS_XRAY_CONTEXT_MISSING=LOG_ERROR # log error instead of throwing an exception # when x-ray context is missing export AWS_PROFILE=appliscale-dev # profile to be used while calling aws cli
- 98. Serverless - Invoke Locally JSON file with an event which will be sent to your lambda function. Full payload can be retrieved from CloudWatch logs. { "Records":[ { (...)

- 99. Serverless - Invoke Locally serverless invoke local --function catrekognition --path event.json You need to configure your AWS credentials as this will call real AWS services (S3, Rekognition, DynamoDB).
- 100. Serverless - Invoke Locally There is a way to use local DynamoDB. To do that, first run the database locally as described here: http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.html Then, modify the source code pointing your DynamoDB client to the local service: dynamoDb = new AWS.DynamoDB.DocumentClient({ endpoint: new AWS.Endpoint('http://localhost:8000') }); Thats it!
