Agenda

Why PaaS matters to developers

Overview of Cloud Foundry

Getting started with Cloud Foundry

Consuming Cloud Foundry services

2

Let’s imagine that you want to deploy an app...

Do you know how much hardware to buy?

Can you afford it?

How long does it take to approve, buy and install?

Who is going to set it up?

What happens if the traffic increases 10x?

Can we afford a test lab?

3

Cloud computing empowers us to deal with these challenges...

4

Cloud computing defined

IT delivered as a service

Over the internet

Self-service

But you need to configure and maintain the operating systems, the app servers and the databases etc.

Ways to use Cloud Foundry

23

Installing vmc on Windows

24

Install the vmc gem

Installing vmc on Mac OSX

25

$ bash -s stable \ <<(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

Use Ruby Version Manager http://beginrescueend.com/

$ gem install vmc

$ rvm install 1.9.2$ rvm use 1.9.2

Example vmc commands

26

$ vmc target <any cloud>

$ vmc login <credentials> $ vmc push <my-app>

! > bind services? Yes

$ vmc update <my-app>

$ vmc instances <my-app> +100

Logging into CloudFoundry.com

27

$ vmc target api.cloudfoundry.comSuccessfully targeted to [http://api.cloudfoundry.com]

$ vmc loginAttempting login to [http://api.cloudfoundry.com]Email: [email protected]: ********Successfully logged into [http://api.cloudfoundry.com]

VMC CLI DEMO

28

vmc push optionally creates manifest.yml

Scale the application

$ vmc instances cf1 +2Scaling Application instances up to 3: OK

44

Survey application demo

45

Uses MySQL and MongoDB

46

@Entitypublic class Customer {

@Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id;

private String firstName;

private String lastName;

@RelatedDocument private SurveyInfo surveyInfo;

public class Survey {

String question;

String answer;

public class SurveyInfo {

private List<Survey> questionsAndAnswers = new ArrayList<Survey>();

public List<Survey> getQuestionsAndAnswers() { return questionsAndAnswers; }

Stored in MySQL

Stored in Mongo

Bindings exposed through VCAP_SERVICES environment variable

48

{ "mysql-5.1": [{

"name": "mysql1", "label": "mysql-5.1",

"plan": "free", "tags": ["mysql", "mysql-5.1", "relational"],

"credentials": {

"name": "da81b57c25cca4c65929a223f0ed068a0",

"host": "172.99.99.99",

"port": 3306,

"username": "secretusername",

"password": "secretuserpassword"

....

}

}] }

Accessing bound services - low-level

49

var services = JSON.parse(process.env.VCAP_SERVICES);var creds = services['mysql-5.1'][0].credentials

configure do services = JSON.parse(ENV['VCAP_SERVICES']) mysql_key = services.keys.select { |svc| svc =~ /mysql/i }.first mysql = services[mysql_key].first['credentials'] mysql_conf = {:host => mysql['hostname'], :port => mysql['port'], :username => mysql['user'], :password => mysql['password']} @@client = Mysql2::Client.new mysql_confend

Accessing bound services - high-level, Spring/Java

50

<bean id="dataSource" class="…"> … DataSource for MySQL instance … </bean>

reconfigured automatically

CloudEnvironment environment = new CloudEnvironment();RdbmsServiceInfo mysqlSvc = environment.getServiceInfo("mysqlService", RdbmsServiceInfo.class);RdbmsServiceCreator dataSourceCreator = new RdbmsServiceCreator();DataSource dataSource = dataSourceCreator.createService(mysqlSvc);

<cloud:data-source id="dataSource" service-name="mysql1"> <cloud:pool pool-size="1-5"/> <cloud:connection properties="charset=utf-8"/></cloud:data-source>...

Accessing bound services - high-level, Ruby

51

RedisHost = "127.0.0.1"

RedisPort = 10000

$r = Redis.new(:host => RedisHost, :port => RedisPort) if !$r

reconfigured automatically

production:

adapter: sqlite3

database: db/production.sqlite3

rewritten automatically

Recap…

52

Services :

• SQL and NoSQL databases

• Message broker

• ...

Service Bindings

• VCAP_SERVICES environment variable

• JSON Format

Framework-dependent ways of accessing the bindings:

• Parse JSON

• ...

• Spring, Sinatra and Rails have auto-reconfiguration

Services are great but what if we want to

Use database tools?

Use the services from JUnit integration tests?

53

Using Caldecott to tunnel into your services

54

gem install caldecott

55

Caldecott Demo

56

Running JUnit test with Caldecott

58

Configure your test code to use port + connection info

Summary

Cloud Foundry is a remarkably easy way to deploy your applications
