The Cloud Foundry Bootcamp document provides an overview of a Cloud Foundry bootcamp presented in Portland in 2012. It was written by Chris Richardson and presented by Monica Wilkinson and Josh Long. The agenda covers why Platform as a Service (PaaS) matters to developers, an overview of Cloud Foundry, getting started with Cloud Foundry, the Cloud Foundry architecture, using Micro Cloud Foundry, and consuming Cloud Foundry services.

How long to get the servers?
Who is going to set up the servers?

Tomcat, and MySQL?

This simple, monolithic architecture is
inadequate

13. Need to handle massive loads and the data explosion
Need scalable architectures
 Application tier:
• Replicated/clustered servers
• Modular so that components can be scaled differently
• Asynchronous architecture - communication via a message
broker
 Database tier:
• Replication
• Sharding
• Polyglot persistence: Relational, NoSQL, NewSQL
databases
11

14. Scaling development

 Strongly coupled components makes development difficult
 Forces multiple developers/teams to synchronize development efforts
 Obstacle to frequent, independent deployments
 Increases risk of failure - need to redeploy everything to change one thing 12

16. Developing and testing these applications
is even more challenging

17. Let’s imagine you are fixing a bug
and want to run some JUnit
integration tests...
?
Who is going to setup your sandbox:
MySQL, RabbitMQ, MongoDB, ....?

19. Platform-as-a-Service is the solution
Deployment Services

Application management + NoSQL databases
Easy scaling up and down Message Broker

76. About the staging plugin
 Framework specific
 Creates a zip file = black box
• Contains everything necessary for DEA to run the application
• Two scripts: start.sh, stop.sh
49

77. Staging plugin for the Spring framework
 Adds CloudAutoStagingBeanFactoryPostProcessor bean:
• Modifies bean definitions
• Implements auto-reconfiguration
 Defines CloudApplicationContextInitializer in web.xml
• Activates cloud profile
• Defines PropertySource for CloudEnvironment properties

84. Self Healing Infrastructure
 If an application instance crashes
• DEA detects unexpected exit => DEA broadcasts message
• Routers remove instance from routing
• Health manager notifies Cloud Controller
• Cloud Controller re-launches instance
 If an DEA VM crashes
• Application instances become unavailable
• Health Manager notices the missing instances and notifies the
Cloud Controller
• Cloud Controller requests application instances to be started
• Existing DEA will reply and start the applications

85. But where are the VMs?!?
 Cloud Foundry has a layered architecture
• Cloud Controller, DEA, … layer = processes
• VM management layer
 Benefits: decoupling, simplicity, ….
 CloudFoundry.com creates vSphere VMs running different Cloud Foundry
components

105. Offline Micro Cloud Foundry
 The problem:
• Cloud Foundry accessed via hostname, which is pretty cool
• Hostname resolved by DNS server ==> laptop needs to be online
 The solution:
• Micro Cloud Foundry now supports true offline mode
• New command:vmc micro
• Reconfigures DNS on your machine to resolve *.cloudfoundry.me locally
• Requires: vmc 0.3.16.beta4 or higher, on Mac VMware Fusion 4.x

120. 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;
}

122. 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"
....
}
}]
}

123. 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

129. 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
86

130. Services are great but what if we want to
Use database tools?
Use the services from JUnit integration tests?
87
