So What? • Zero admin • Truly transparent scaling • No vendor lock-in • Lower costs ☁ { }

Slide 11

Slide 11 text

FaaS Pricing • Billed by 1) GB-second rate + 2) Cost per request • 128 MB × (1 GB/1024 MB) × 100 ms × (1 s/1000 ms) = 0.0125 GB-s • 400,000 GB-s, 1M requests free per month

• More abstraction • More systems complexity • Latency • Vendor lock-in (sort of…) So What? • Zero admin • Transparent scaling • No vendor lock-in • Lower costs ☁ { }

FaaS Use Cases • Event-oriented, short-lived (minutes) execution 1. Trigger 2. Data pipeline 3. API service

Slide 15

Slide 15 text

Trigger • On-demand or scheduled tasks Action Lambda Event { }

Slide 16

Slide 16 text

Ex: Lunchbot Action Lambda Event Post to Slack webhook Scrape Instagram, Build notification Daily timer { }

Slide 17

Slide 17 text

Ex: Newsbot Action Lambda Event Post to backend Query news feeds and apply filters Hourly timer { }

Slide 18

Slide 18 text

Ex: Server Health Alarms Action Lambda Event Post to Slack webhook Build notification Environment health check { }

Slide 19

Slide 19 text

Data Pipeline • Real-time log/file/media processing • e.g. resize and compress image upon upload Lambda Sink Storage Source { }

Slide 20

Slide 20 text

Ex: Server Log Analytics • Can be used with AWS Athena (“serverless” SQL) Lambda Sink Storage Source Parse user agent strings Post to Kinesis Firehose Web server access logs Write to S3 { }

Slide 21

API Service • Microservices, Proxy backends Lambda API Gateway Data Store Client { }

Slide 22
