Serverless and you - where do i run my stateless code
- 1. Serverless and you Where do I run my stateless code? @gabidavila gabi.dev Gabi D'Ávila Ferrara Developer Advocate - Google Cloud
- 2. Serverless Definitions Serverless: • Focus on code • Don't worry about infrastructure • Auto-scaling (+ scaling to 0) • Pay what you use Stateless: • Doesn't store data • Doesn't store application state • No persistent storage 2@gabidavila
- 3. Let's talk about servers @gabidavila
- 4. Is serverless the new "Shared Hosting"? 🤔
- 5. "It works on my machine" - Every technical practitioner ever @gabidavila
- 6. The "good" old days • Named servers: • Zeus, Thor, Odin, you get the gist! • Certificate/user management by a SysAdmin • FTP or SCP: • Try uploading Magento via FTP... • SVN or CVS to deploy code (if even!) • Almost zero automation 6@gabidavila
- 7. The "modern" approach • Machines are a commodity • CI/CD • Automation: Chef, Terraform, Puppet... • Easier to scale horizontally • Don't forget the keywords of the moment: • Containers, Kubernetes 7@gabidavila
- 9. Is Kubernetes serverless ? @gabidavila
- 11. Should I use serverless for Blockchain? @gabidavila
- 13. Serverless on Google Cloud Platform 13 Cloud RunCloud Functions App Engine @gabidavila
- 14. Cloud Functions 14 • Single-purpose • Mapped to Events or Triggers • NodeJS - 10 / 8 / 6 (deprecated), Python, Go • Use cases: • Microservices • IoT • Data Processing / ETL • Lightweight APIsCloud Functions @gabidavila
- 18. 18 Cloud Functions def classify(request): request_json = request.get_json() if request.args and 'message' in request.args: tweet = get_tweet(request.args.get('message')) elif request_json and 'message' in request_json: tweet = get_tweet(request_json['message']) else: return u'Please inform a message' sentiment = get_sentiment(tweet['text']) return flask.jsonify( text = tweet['text'], screen_name = tweet['screen_name'], sentiment = sentiment['sentiment'], score = sentiment['score'], magnitude = sentiment['magnitude'] )
- 19. App Engine Standard 19 • Deploy an App • Choose between 6 popular platforms • Scale from 0 to "planet scale" • Fully managed App Engine @gabidavila
- 20. Services and Versions • Create services inside of the same App Engine project • Create different versions (and serve them!) through different services • Use cases: • Do A/B testing • Create dev, test, staging and prod environments! 20 App Engine Standard @gabidavila
- 21. 21 App Engine Standard Service - dev Service - prod App Engine Receives traffic Version A InactiveInactive Version B Inactive Version A Active Version B Active Inactive Version C Active @gabidavila

- 27. Cloud Run (beta) 27 • Fully Managed or on Anthos • Container based • Revision based • Scale to zero or up and the amount of requests: • requests = concurrency /instance * max instances • Up to 2Gi of memory/revision • Cloud Run on Anthos limits by your GKE cluster Cloud Run @gabidavila
