Nouveaux usages, nouveaux challenges

• Nouveaux besoins
– Toujours plus de clients (explosion du mobile)
– Viralité des réseaux sociaux
– Besoin de notification en quasi temps réel

• 1 war monolithique
– difficile à scaler, approche tout ou rien
– difficile à maintenir

Maintenant, à vous !

25

Contrôler le Cloud

28

Rappel des concepts

• CloudFoundry, c’est des applications et des services
• On associe les deux via des bindings

• CloudController = REST API

• nombre d’instances, urls, mémoire, logs, stats, etc...

29

Consommer des services

31

Un point commun entre tous les OS

“ Environment Variables [...] unlike custom config
files, or other config mechanisms such as Java
System Properties, are a language- and OS-
agnostic standard
The Twelve Factor App, http://www.12factor.net

32

Auto-reconfiguration

34

Mais mes applis ressemblent à ça...

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/mydb" />
<property name="username" value="myuser" />
<property name="password" value="s3cr3t" />
</bean>

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="myPersistenceUnit" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
</bean>
</property>
</bean>

35

Bon ben voilà, merci d’être venus...

37

Deux datasources sont dans un bateau

38

Configuration explicite

40

Namespace <cloud: />

<cloud:data-source id="myDataSourceBean" service-name="boundServiceName" />

<cloud:mongo-db-factory id="mongoDbFactory" write-concern="FSYNC_SAFE">
<cloud:mongo-options connections-per-host="10" max-wait-time="2000" />
</cloud:mongo-db-factory>



41

Les profils
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"...>

<bean id="mongoTemplate"
class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg ref="mongoDbFactory" />

<beans profile="default">

Et si mon appli n’utilise pas Spring ?

org.cloudfoundry.runtime.env.CloudEnvironment

RdbmsServiceInfo serviceInfo = cloudEnvironment.getServiceInfo(
“postgres-reporting”,
RdbmsServiceInfo.class
);

serviceInfo.getDatabase();

serviceInfo.getHost();

serviceInfo.getPort();

serviceInfo.getUserName();

serviceInfo.getPassword();
