logmanagement

  • loggregater
  • enable connect 3rd party service
$ cf cups <LOGSERVICE> -l syslog://<HOST>:<PORT>
$ cf bind-service <APP> <LOGSERVICE>
$ cf restage

Application Monitoring Tool

  • NewRelic

autoscaling

  • CF can allow applications to be automatically scaled
  • AutoScaling
  • Must be installed by administrator

Zero-Downtime Deployments

  • Blue/Green Deployment
  • BG Deployment was used when rolling upgrade
$ cf push blue -p app.war -n always-reliable -i 4
$ cf push green -p app.war -n temp-route -i 4

# duplicate route-> disconnect blue
$ cf map-route green cfapps.io -n always-reliable
$ cf unmap-route blue cfapps.io -n always-reliable

# temp route delete
$ cf unmap-route green cfapps.io -n temp-route

# delete app
$ cf delete blue

Cloud Foundry Architecture

  • CloudFoundry v1.5<~ はDIEGOになる
  • Load-Balancer -> Router
  • BlobStore(NFS Store, droplet, buildpack...)
  • CC DB(MetaData in cloud)
  • CloudController
  • AZ > DEA > Warden(Droplet)
  • Service Broker*s(
  • HealthManager
  • UAA/Login Servers
  • NATS
  • BOSH(CPI --- IaaS)

UAA: User Authorization and Authentication DEA: Droplet Execution Agent

LoadBalancer(HAProxy)

  • ルータの前段に構える
  • Floting IPを持つ
  • Load-balancing
  • SSL-Termination
  • HAProxy or F5, NSX
  • SPOF

Router

  • 内部のHTTP通信を担っている(System & Service)
  • supports websockets
  • SPOF

Cloud Controller＊

  • Command, Control のエンドポイント

BlobStore＊

  • ApplicationPackage,Dropletsを格納している
  • SPOF

CCDB

  • Stores Information
  • App Name

AZ

DEA

  • Linux VM
  • manages application lifecycle
  • DIEGOになるとDockerを管理するようになる
  • NATS message bus を通じて状態を通知している

WardenContainer

  • LightweightVM(LXC)
  • Dropletsを動かしている

Service Broker

  • サービスカタログ

HealthManager

  • actual stateを管理
  • expected stateかモニタリング
  • CloudControllerに状態を伝える

Messaging(NATS)

  • Single NATS/CloudFoundry

UAA/LoginServices

  • OAuth2.0
  • Token Server
  • ID Server
  • OAuth Scopesand SCIM
  • Login Server
    • UAA DB
    • SAML Suppport(for SSO)
    • Active Directry Support with VMware SSO Appliance
  • Access auditing

Cloud Foundry BOSH

  • Tool chanin
  • CloudProviderInterfaceによりIaaSを隠ぺい
  • IaaS installer(v1.5-> openstack, aws)
  • VMcreation and management
  • HA(Restart DEA, CF Internal Processes)

Health Manager

Continuous Delivery adn Cloud Foundry

  • SCM
  • CI
  • CD
  • CI + automated deployment

DIEGO

  • DIEGO = DEA in GO
  • Metron Agent がすべてのログをとる
  • Brain(MetricsServer) が性能をとっている（HealthManager)
  • Converger: Scaleup,Scaleout
  • Auctioneer: Dropletを稼働させるCellを選択（スケジューラ）
