 Why PaaS matters to developers
 Overview of Cloud Foundry
 Getting started with Cloud Foundry
 Consuming Cloud Foundry services

3. 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

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

5. Cloud computing defined
IT delivered as a service
Over the internet
Self-service
Pay per use

6. The three layers of cloud computing
SaaS
PaaS
IaaS
6

7. Benefits of IaaS
Agility
Pay per use
Elasticity
But you need to configure and maintain
the operating systems, the app servers and
the databases etc.

8. Need to move up the stack

23. Ways to use Cloud Foundry
23

24. Installing vmc on Windows
Install the vmc gem
24

25. Installing vmc on Mac OSX
Use Ruby Version Manager http://beginrescueend.com/
$ bash -s stable
<<(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
$ rvm install 1.9.2
$ rvm use 1.9.2
$ gem install vmc
25

26. Example vmc commands
$ vmc target <any cloud>
$ vmc login <credentials>
$ vmc push <my-app>
! > bind services? Yes

26

27. Logging into CloudFoundry.com
$ vmc target api.cloudfoundry.com
Successfully targeted to
[http://api.cloudfoundry.com]
$ vmc login

28. VMC CLI DEMO
28

30. vmc push optionally creates manifest.yml
applications:
Captures the information that vmc push gathered
target/: vmc doesn’t have to ask you again
name: example1
url: cer-example1.cloudfoundry.com
framework:
name: java_web
info:
mem: 512M
description: Java Web Application
exec:
mem: 256M
instances: 1
30

31. Scale the application
$ vmc instances cf1 +2
Scaling Application instances up to 3: OK
$ vmc stats cf1
+----------+-------------+----------------+--------------+--------------+
| Instance | CPU (Cores) | Memory (limit) | Disk (limit) | Uptime |

41. Creating a service instance
$ vmc create-service mysql --name mysql1
Creating Service: OK
$ vmc services
============== System Services ==============
+------------+---------+---------------------------------------+
| Service | Version | Description |
+------------+---------+---------------------------------------+
| mongodb | 1.8 | MongoDB NoSQL store |
| mysql | 5.1 | MySQL database service |
| postgresql | 9.0 | PostgreSQL database service (vFabric) |

+------------+---------+---------------------------------------+
=========== Provisioned Services ============
+-------------+---------+
| Name | Service |
+-------------+---------+
| mysql1 | mysql |
+-------------+---------+

42. Binding a service to an application
$ vmc push cer-spring --path web/target/
Application Deployed URL [cer-spring.cloudfoundry.com]:
Detected a Java SpringSource Spring Application, is this correct? [Yn]:
Memory Reservation (64M, 128M, 256M, 512M, 1G) [512M]:
Creating Application: OK
Would you like to bind any services to 'cer-spring'? [yN]: y [yN]: y

43. Binding a service to an application
$ vmc bind-service mysql1 myapp
Binding Service [mysql1]: OK
Stopping Application 'myapp': OK
Staging Application 'myapp': OK
Starting Application 'myapp': OK
$

44. Binding in STS
44

45. Survey application
demo
45

46. Uses MySQL and MongoDB
@Entity
public class Customer { Stored in MySQL
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String firstName;
private String lastName;
Stored in Mongo
@RelatedDocument
private SurveyInfo surveyInfo;
public class SurveyInfo { public class Survey {
private List<Survey> questionsAndAnswers = new ArrayList<Survey>(); String question;
public List<Survey> getQuestionsAndAnswers() { String answer;
return questionsAndAnswers;
}
46

48. Bindings exposed through VCAP_SERVICES environment variable
{ "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"
....
}
}]
}
48

49. Accessing bound services - low-level
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_conf
end
49

50. Accessing bound services - high-level, Spring/Java
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>
...
reconfigured automatically
<bean id="dataSource" class="…">
… DataSource for MySQL instance …
</bean>
50

51. Accessing bound services - high-level, Ruby
reconfigured automatically
RedisHost = "127.0.0.1"
RedisPort = 10000
$r = Redis.new(:host => RedisHost, :port => RedisPort) if !$r
rewritten automatically
production:
adapter: sqlite3
database: db/production.sqlite3
51

52. Recap…
 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
52

53. Services are great but what if we want to
Use database tools?
Use the services from JUnit integration tests?
53

54. Using Caldecott to tunnel into your services
54

55. gem install caldecott
55

56. Caldecott Demo
56

58. Running JUnit test with Caldecott
Configure your test code to use port + connection info
