13 Source of Truth Database

14 Source of Truth Database ● Migration headaches ● Manage connections ● Performance

15 Source of Truth Database Logging { "message": "Downloaded img", "userId": "1234", "imgId": "1d3x5", "service": "download-server", "time": "1509385330" }

16 Two Kinds of Logs Server logs [Wed Oct 11 14:32:12 2000] [info] [client ● Debugging 127.0.0.1] image 1d3x5 downloaded by userId 1234 ● Support

19 Centralize

20 Metric Collector import observatory obs = observatory.Tracker() obs.track('search_made', { 'query': event.query, 'n_results': len(resp['data']), 'user_id': user_item.id })

21 Metric Collector Enrich / Conform import observatory obs = observatory.Tracker() obs.track('search_made', { REST API 'query': event.query, Lambda 'n_results': len(resp['data']), 'user_id': user_item.id })

22 Metric Collector import observatory obs = observatory.Tracker() obs.track('search_made', { REST API 'query': event.query, Lambda Redshift 'n_results': len(resp['data']), 'user_id': user_item.id }) S3

23 After ● Centralized metrics ● Log enrichment ● Persistent store REST Lambda Redshift S3

24 2. Debugging is painful

25 Before Filesystem EC2 CloudWatch Lambda EC2 Filesystem

26 Centralize

27 EC2 Stream Lambda EC2

28 EC2 Lambda CloudWatch EC2

29 EC2 Lambda CloudWatch Consumer EC2

30 ES EC2 SAAS Lambda CloudWatch Consumer S3 EC2

31 After ● Elasticsearch ● Search by UUID

32 But! What does the full flow of a request look like?

33 Correlation ID UUID

34 Correlation ID ● Create for any external call CID External Service A Request

35 Correlation ID ● CID passed everywhere CID Service B External Service A Request Service C

36 Correlation ID In ES → filter �y CID

37 3. Building services is slow

38 Before ● Online console ● Zip file deployment ● Doesn’t s�ale

39 Infrastructure as Code

40 Infrastructure as Code ● Serverless Framework ● Template -> service ● Rapid deployment

41 # serverless.yml service: users provider: name: aws runtime: nodejs6.10 stage: dev functions: usersCreate: handler: users.create events: - http: post users/create resources: Resources: usersTable: Type: AWS::DynamoDB::Table Properties: TableName: usersTable AttributeDefinitions: - AttributeName: email AttributeType: S

42 # serverless.yml service: users Microservice provider: name: aws runtime: nodejs6.10 stage: dev functions: usersCreate: handler: users.create Internet Lambda events: gateway handler - http: post users/create S3 resources: Resources: usersTable: Type: AWS::DynamoDB::Table Properties: TableName: usersTable AttributeDefinitions: Dynamodb - AttributeName: email AttributeType: S

43 # serverless.yml service: users provider: name: aws runtime: nodejs6.10 stage: dev STAGE: ${opt:stage, self:provider.stage} functions: usersCreate: handler: users.create events: - http: post users/create resources: Resources: usersTable: Type: AWS::DynamoDB::Table Properties: TableName: usersTable AttributeDefinitions: - AttributeName: email AttributeType: S

44 # serverless.yml service: users provider: name: aws runtime: nodejs6.10 stage: dev ● Service info as ENV vars STAGE: ${opt:stage, self:provider.stage} functions: usersCreate: handler: users.create events: - http: post users/create resources: Resources: usersTable: Type: AWS::DynamoDB::Table Properties: TableName: usersTable AttributeDefinitions: - AttributeName: email AttributeType: S

45 # serverless.yml service: users provider: name: aws runtime: nodejs6.10 stage: dev ● Service info as ENV vars STAGE: ${opt:stage, self:provider.stage} ● Inject in logs functions: usersCreate: handler: users.create events: - http: post users/create resources: import observatory Resources: obs = observatory.Tracker() usersTable: Type: AWS::DynamoDB::Table Properties: obs.track('search_made', { TableName: usersTable 'query': event.query, AttributeDefinitions: - AttributeName: email 'n_results': len(resp['data']), AttributeType: S 'user_id': user_item.id })

46 After ● Rapid dev ● Source controlled ● Log enrichment

47 4. Server time == $$$

48 Before ● Bursty ● ETL servers idle

49 Transient Resources ● Pipeline: ○ Spin up EC2 ○ Terminate ETL EC2 EC2 DB

50 FAAS Resources ● Pipeline: ○ Discretize work ○ Lambda fleet ○ Inherently transient Worker Listener Worker DB Worker

51 After ● Faster ● Cheaper ● Highly scalable ETL
