serverless openstack 101
- 1. Serverless with OpenStack 101 2018/07/17 Serverless Tokyo Meetup #8 (in 構造計画研究所) @naoto_gohko
- 2. 少しお話の時間をください
- 3. LT presenter(It’s me) • Naoto Gohko / 郷古 直仁 (@naoto_gohko) • Cloud Service development divistion, GMO Internet Inc., • 最近の活動主体 • Japan OpenStack user会 • その他参加勉強会など • Rancher JP, PaaS, Serverless, SDNなど @MikumoConoHa
- 6. ServerlessとFaaS(自分の捉え方) FaaS(Function as a service) • コードのみの実行できる(Function), サービスではない(not Services) - “down when done” • Event driven programming model • Scale – “infinite”, transparent for dev, handled by Platform/Framework • Pay-per use consumption model API gateway BaaS(Backend as a service) • 認証、メッセージング、AI、chat DataStore service • noSQL(CRUD datastore), Object Storage(S3, Swift) Workflows
- 8. Serverlessが必要な現場 (use case) • Data Processing • Services for web and mobile apps • Ex) SPA (Single Page Application) (Vm instanceを全く使わない開発、webIDEのみでの開発) • Other workflow/automation • DevOps automation ( ex; github build flow ) • IoT, Alexa, ChatBot • IFTTT, slack • Etc.
- 11. OpenStack FaaS projects #1 2016/12 • OpenStack Picasso (IronFunctions runtime) https://launchpad.net/picasso • Github: https://github.com/openstack/picasso “openstack fn” コマンドで統合的に利用できた Telemetry, Swift Object Storageでの利用しか開発側が当時想定 しない (もったいない) 残念な展開に
- 13. Picassa last issue: 2017/02/28 • IronFunctions • Kubernetesなどのruntime環境 そのまま発散、開発止まる
- 15. OpenStack FaaS projects #2 2017/November 6-8 SYDNY summit • OpenStack Qinling (本命) https://launchpad.net/qinling • Yourtube(demo): https://www.youtube.com/watch?v=K2SiMZllN_A • Github: https://github.com/openstack/qinling FaaS for OpenStack 1.0としてOpenStack “Rocky” でリリースされる 予定 “openstack function <hogehoge> “ としてCLI Functionは今の所Pythonのみらしい
- 17. FaaS for OpenStack : Qinling
- 19. Alternative; k8s integration K8s := scalable container runtime
- 20. Why to service Serverless on k8s • 1) If you are already running k8s cluster • On Public/Private cloud • 2) Unify multiple clouds with one Serverless Framework Ex) • on Public; DigitalOcean k8s • on Private; OpenStack cloud k8s • 3) When using k8s simply as a scalable execution environment
- 21. OpenStack with Opensource FaaS #1 Iron Function (ex: on kuberrnetes) • Functions • Functions-ui Fission (Platform9) (on kubernetes) https://fission.io/
- 22. OpenStack with Opensource FaaS #2 Kubeless (on kuberrnetes) https://kubeless.io/ OpenWhisk (on kubernetes) https://openwhisk.apache.org/ Funktion (Red Hat has stopped funding this OSS project, 2017/11/29) Need to fork!!
- 24. Serverless framework for FaaS #1 Iron Function (ex: on kuberrnetes) • Functions • Plugin : nothing
- 25. Serverless framework for FaaS #2 Kubeless (on kuberrnetes) https://kubeless.io/ https://github.com/serverless/serverless-kubeless OpenWhisk (on kubernetes) https://openwhisk.apache.org/ https://github.com/serverless/serverless-openwhisk
- 26. Billingの問題 fuction cpu time (API log)
- 27. Ingress (API gateway) API log API gateway • APIのアクセスログからfluentdなどで計測情報を取得 • API time(ms) • API access count(number of X) Kong, etc. Docker(k8s) runtime • 精密には、functionを実行するdocker(Container Runtime)の proc IDのCPU timeの測定が必要
- 28. Private cloudの Azure Stack で App Service と Functionsの 利用 普通にbillingサービスまである さすがだ
- 29. Summary: Serverless with OpenStack 101 Qinling project (OpenStack) • RuntimeはKubernetesでscaleできる • Functionはpython(いまのところ) • OpenStackとの統合度合いは良さそう • Serverless Frameworkとの互換性もナシ（泣） FaaS on Kubernes on OpenStack • Runtimeだけなら、こちらから選択するのが現実的 • こちにAuth, API gateway, Billingつけるほうがよいか? • Kubeless << k8sのCRDになっているので、FaaS単体としては使いづらい?
- 30. “Serverless Meetup Tokyo #8” ; added after discussion (I thought of later) 追加資料
- 31. Serverless framework for FaaS #3 OpenFaaS https://www.openfaas.com/ Docs: https://docs.openfaas.com/ Github: https://github.com/openfaas/faas (Thanks!! @yoshidashingo) 最近の活発度は一番かもしれません
- 32. OpenFaaSの最近のGoogleTrends OpenFaaSは確かにTrend, github star, github watchと もに多い OpenWhiskは始まりが古い 文、contributersは多い
