Automation Workflow and Hybrid System

• ReleaseRailsAppwithGitlab whenappliedDocker• (CI– CDworkflowwithRailsAppwhenapplyDocker)

• Designauto-scalesystemwithDockeronKubernetesandAWSCloud• ScalablesystemwhenusingonlyAWSCloud• Auto-scalesystemonKubernetesandAWSCloud

Dockerize RailsApps

- Dockerfile- EnvironmentVariables- Gem requirement- Specify Gem with Gemfile and

Gemfile.lock

Gitlab-CI & Gitlab-multi-runner

- Autotest- AutoQ/A- MultipleEnvironmentTesting- AutoReleaseImages- AutodeliveryDockerImagestoDocker-Hub- Autodeployment

Auto-Scaling

• Makethesystemeasierwithscalable• Alltheactionswith automation• Policy scale-up and scale-down

AutoHealing

• Auto define unexpected event of infrastructure• Auto fix

KubernetesArchitecture• Kubernetes isanopen-sourcesystemforautomatingdeployment,scaling,andmanagementofcontainerizedapplications.

• “Writeoncerunforever”

Features focus• Pods• Replication Controller • Services• LBaaS• HPA – Horizontal Pods Autoscaling• Constraint• Label• Namespace• …

HybridsystemArchitecture

• DEV:• MakeITsimple• Easytouse• DocumentsasCode• Notneedtosetup

• OPS• Easytomaintain• Becomehumanops

Disadventage

• Workflow: • Developer must know about system – Devops • Can’t apply docker to all old services• Dockerize old big system is so hard• Personal know-how

YOUR GOAL• Hybrid system with HA, AUTO-HEALING, AUTO-SCALING, AUTO-

DEPLOYMENT…• Easy with “OPS”• Easy with “DEV”
