8. What’s Happening with Applications Today?
§ Frameworks are what really matter
• Developer productivity and innovation
• Reduce time to market
§ New application types
• Mobile, Social, SaaS
• Apps released early and often
§ Data intensive
• Emerging requirements: elasticity, multi-cloud
• Web orientation drives exponential data volumes
§ Deployed on virtual and cloud infrastructures
• Virtualization, Cloud, PaaS

15. Why Cloud Foundry?
Developer Agility
• Friction-free way to develop, test and deploy applications
• Focus on writing applications, not meddling with middleware and infrastructure
Portability without changes
• Write once, test-scale-deploy to private/public clouds without code changes
• Quickly build and test on a laptop and scale to the cloud
Open - The freedom to choose
• Choice of clouds for deployment, industry frameworks, and application services
• Extensible architecture to “future proof” for rapid cloud innovation
• Community open-source project - access, evaluate and contribute

27. Multi-Cloud Flexibility is Critical
§ Make use of both public and private clouds without rewriting your
applications
§ Protect against vendor lock-in
§ Meet different compliance and geographical needs
§ Manage your growth, accommodate peak loads & optimize costs

28. Main Risk: Lock In
Welcome to the hotel california
Such a lovely place
Such a lovely face
Plenty of room at the hotel california
Any time of year, you can find it here
Last thing I remember, I was
Running for the door
I had to find the passage back
To the place I was before
’relax,’ said the night man,
We are programmed to receive.
You can checkout any time you like,
But you can never leave!

35. “ 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
35
37. So, you could...
Use System.getEnv(“VCAP_SERVICES”)
but it’s better to:
<dependency>
<groupId>org.cloudfoundry</groupId>
<artifactId>cloudfoundry-runtime</artifactId>
<version>0.8.2</version>
</dependency>
37
38. CloudEnvironment & Friends
// Gives access to the VCAP_* variables
CloudEnvironment env = new CloudEnvironment();
if (env.isCloudFoundry()) {
// Parses and retrieves info about the service named "mydb"
RdbmsServiceInfo info =
env.getServiceInfo("mydb", RdbmsServiceInfo.class);
// From there, you can either...
info.getHost();
info.getPort();
// ...or create a DataSource with the given info
RdbmsServiceCreator creator = new RdbmsServiceCreator();
DataSource ds = creator.createService(info);
}

43. Auto-reconfiguration
§ Works for Spring, Node, Ruby
§ Spring: Uses a BeanFactoryPostProcessor
under the hood
• adds a jar to your app
• modifies web.xml to load the BFPP
• also adds correct jdbc driver jar
§ Only works if no ambiguity (80% of apps)
• One service of a kind
CONFIDENTIAL
44. Introducing the <cloud:x> namespace
§ For the remaining 20% of apps
• if your app uses e.g. 2 DataSources
• or if you want more control
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

45. <cloud:service-scan />
§ Scans all bound services and creates a bean for each
§ Use @Qualifier to disambiguate:
@Inject
@Qualifier("mysql-source")
private DataSource sourceDS;
@Inject
@Qualifier("mysql-destination")
private DataSource destDS;
CONFIDENTIAL
47. Using Profiles
§ Spring 3.1 introduced the concept of profiles
• A set of beans that can be activated as required
• Usually controlled by spring.profiles.active system property
• Cloud Foundry activates “cloud” profile for you
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<beans profile="profileA">
<bean id="someId" />
<bean id="onlyInProfileA"/>
</beans>
<beans profile="profileB">
<bean id="someId" />

<bean id="always-present" />

§ 40+ unique node types
§ 75+ unique software packages
§ 75+ unique environments
§ 2x/week cf.com updates

§ No-downtime deployments
§ Reliable, robust, repeatable
deployments, updates, capacity
adjustments
§ Small teams manage many

51. Cloud Foundry BOSH
§ Cloud Foundry BOSH is an open source tool-chain for release
engineering, deployment, and lifecycle management of large scale
distributed services
• Prescriptive way of creating releases and managing systems and services
• It is not a collection of shell scripts, not a pile of Perl
§ Built to deploy and manage production-class, large scale clusters
• Production grade Cloud Foundry clusters: 500+ VMs, 40+ jobs, 75+ packages
• Multi-node, multi-tier, complex clusters: e.g., our Gerrit/Jenkins Cluster
§ Built for devops usage and scale by a crack team of veterans
• A project, not a product: command line interface, YAML, etc.
• Continuous improvement, iterative development, rough edges
