Join Datadog for a webinar on monitoring serverless applications with AWS Lambda. You'll learn how to get the most of Datadog's platform, as well ask the following key takeaways: Learn how to set up a Twitter bot that makes API calls with Node.js Deploying Serverless Applications What does observability look like with less infrastructure?

1. Monitoring Serverless Applications
With Datadog

2. Intro
– Rachel White
– Technical Evangelist @ Datadog
– @ohhoe on twitter if you have any additional questions

3. Overview
– Traditional vs Serverless Applications
– Twitter Bots
– Generative Art
– Serverless (AWS Lambda)
– Monitoring a Serverless Application

4. What is Serverless?

5. Traditional Architecture
– LAMP, MAMP, MEAN, JAM
– 100% Uptime
– Full Control over Software Versioning
– Usually Monoliths

6. Microservice Architecture
– Can run across multiple stacks
– Separate Deploys
– Modular

7. Serverless
– Cloud provider executes code
– Don’t have to think about servers at all
– Pay only for what you use
– Easier to adapt to demand at scale

8. AWS Lambda
– Zero Administration
– Automatically allocates compute execution power
– Set code to automatically trigger
– Write in your favorite programming language

10. How do you debug a server that doesn’t exist?
🤔

12. How do you debug a server that doesn’t exist…
in this?

13. Serverless Platform Specific Constraints
Allocated Memory Usage
Cold Starts
API Gateways as Intermediaries
Commonly Called via Queues

17. 3 Step Configuration for Serverless Full Visibility
1. Enable AWS
Integration
2. Add the Forwarder
3. Instrument Your Language

23. Traces, Logs and Metrics Across Infra Platforms

24. Lambda Forwarder

27. Use Datadog to Pivot Between Abstractions
APM for Service / Application Level Problems
Serverless Metrics & Dashboards for Platform State
Service Map for Overall Application Architecture
Metrics for Overall Business Processes / State
Enrich with RUM for Visibility into End User Experience

28. Twitter Bot Time

29. Serverless Framework
– Open Source CLI
– Write once, Deploy many
– Quick AWS integration
– serverless.com

30. AWS
– Lambda function
– S3 bucket
– Cloudflare cron trigger

31. Datadog
– AWS integration
– Lambda Forwarder
– AWS X-Ray for distributed application tracing

32. Node.js Application
– Create base64 dataURI image
– Different every time
– Pulls color info from colourlovers
– AWS-SDK
– Twit - API client for Node

33. Twitter Bots
– Used to be very popular pre-closed API time
– Image Based
– Markov Chain / ML text gen
