Motivation - Be a cloud- friendly engineer

Once upon a time, (90s - 2000s) Working with a web application, you used to use ● Physical servers ● Instruction text ● Historical shell script ● Deploy and pray (aka お祈りデプロイ)

201x - Now, we have Cloud tech. & Configuration files!!! - Dockerfile, Procfile, etc. Doing deploy is only .. - git push - press deploy button - speak to chatbot Eg. Configuration file FROM ruby:2.3 # throw errors if Gemfile has been modified since Gemfile.lock RUN bundle config --global frozen 1 RUN mkdir -p /usr/src/app WORKDIR /usr/src/app ONBUILD COPY Gemfile /usr/src/app/ ONBUILD COPY Gemfile.lock /usr/src/app/ ONBUILD RUN bundle install ONBUILD COPY . /usr/src/app RUN apt-get update && apt-get install -y nodejs --no-install-recommends && rm -rf /var/lib/apt/lists/* RUN apt-get update && apt-get install -y mysql-client postgresql-client sqlite3 --no-install-recommends && rm -rf /var/lib/apt/lists/* EXPOSE 3000 CMD ["rails", "server", "-b", "0.0.0.0"]

!!!One great way to learn modern web dev is going through cloud technology !!!

Eye-opening Experience - Google AppEngine and me

GCP Workshop

Schecule ● #1 12/2 GCP overview, GCE ● #2 12/16 GCE ● #3 1/13? App Engine ● #4 1/27? App Engine ● #5 2/?? Kurbenetis ● Gradually Difficult

注意 ● 課金されるかもごめんね ● 経験者が多いので難しめです ● 途中から来ないでもいいよ

Overview at Cloud tech.

Cloud tech. ● IaaS ● PaaS ● mBaaS ● FaaS ● (orchestration tool)

IaaS: Infrastructure as a Service ● Such as; Amazon EC2, Google Compute Engine (GCE) ● Rental Infrastructure (server, data store, network) on demand ○ Similar: virtual machine (VMWare, VirtualBox) ● Build and run web application on freehand ○ No restriction for user web application ●

PaaS: Platform as a Service ● Such as; ElasticBeans, AppEngine, Heroku ● Go publish web app by `git push` ● Platform takes care of everything about web app ○ Network, scaling, monitor, logging ● Strong restriction ○ Limited languages, frameworks, networks, version ●

mBaaS: Mobile Backend as a Service ● Such as; Firebase, Parse.com(dead) ● For Mobile(iPhone app, Android App) ● Datastore, Authentication, Push, ads, ...

FaaS: Function as a Service ● Such as; Amazon Lambda, Cloud functions ● Serverless - ultimate web app ● Compose functions to make web app ○ Charge per-function invocation ● Stronger Restriction!! ○ Languages(JS?), no framework, complete vendor lockin

Orchestration ● More and more complicate web application ○ App Servers, Load balancer, Proxy server, Database, 3rd party API calls ● Problems; ○ Hard to manage a configuration or architecture ○ Hard to set up in local environment ● Describe a configuration of web application

Why GCP ● AWS is the biggest player, though ● GCP is ○ Cheap ○ Cutting-edge ○ Made by Google ○ For Startups ○

Adopted by cutting-edge companies ● Pokemon Go, Nintendo (AppEngine) ● メルカリアッテ, Mercali (AppEngine) ● Abema TV, Cyberagent (GCE, GKE) ● DeNA (AppEngine) ●

Any questions?

Let’s start with workshop

Login at console https://console.cloud.google.com/

Console ● Dashboard ● Project ● Menu (〓)

Horror story; AWS 破産 ● GCP has wider free tier than AWS but… ● Charging point ○ Instance ○ Storage ○ Traffic ○ API calls ●

Set a budget alert ● Notice earlier when forget to turning off a instance ● [〓] → billing → `Budgets & alerts` → `CREATE BUDGET` ● Input like this ●

Create first project ● https://console.cloud.google.com/cloud-resour ce-manager ● Click `CREATE PROJECT` ● Type `helloworld` in project name and create ● Wait a few min

Launch a Wordpress ● https://console.cloud.google.com/launch er ● Select `wordpress`

Tour VMs ● https://console.cloud.google.com/compu te/instances → click `wordpress-1` ● [SSH] ● [STOP] Disks !!!

VM ● Zone ● Machine Type - CPU/Memory ● OS ● Storage ● Firewall ●

Delete VM & Project ● VM instances → [DELETE] ● Delete Project https://console.cloud.google.com/cloud-resource-man ager ○ Type project id ● まめに消すこと

Pricing ● https://cloud.google.com/compute/pricing ● Point ○ CPU ○ Volume ○ Traffic ○ Always Free

Install Google Cloud SDK ● Cloud SDK - Command line tool ● Open Terminal.app and `brew cask install google-cloud-sdk` ● https://cloud.google.com/sdk/gcloud/?hl=ja

Take a break

Setup cloud sdk - `gcloud init`

Create project by cloud sdk - `gcloud projects create your-project-name` - Must be unieque ERROR: (gcloud.projects.create) Project creation failed. The project ID you specified is already in use by another project. Please try an alternative ID. - `gcloud config set project your-project-name`

Create VM - `gcloud compute instances create gaminstance --machine-type f1-micro --image-family ubuntu-1710 --image-project ubuntu-os-cloud` - us-west-a https://cloud.google.com/compute/docs/instances/create -start-instance

Ssh an instance - `gcloud compute ssh instance-1`

Delete - `gcloud compute instances delete instance1`

GCE Tutorial https://console.cloud.google.com/getting-started `Build a compute engine application`

演習 Rails ● 次のインスタンスを作る ○ MachineType: n1-standard / OS: Ubuntu 16.04 / Zone: us-west/ allow-http-access ● Ssh でインスタンスにログインする ● Ruby をインストール ● Rails をインストール ● `rails new` ● sudo ./bin/rails server -p 80 -b 0.0.0.0

Shell script sudo apt-get update sudo apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3 libgdbm-dev sudo apt-get install ruby-dev sqlite3 libsqlite3-dev nodejs sudo gem install rails rails new HelloApp cd HelloApp # 元気のある人はDockerfileを作ってください

次回 ● Dockernize ● Network ● Cost estimation ● もうちょっと現実的な構成 ● App Server Compute Engine Autoscaling App Server Compute Engine Autoscaling Cloud Load Balancing

Homework ● Install docker
