What is Cloud Computing?
Cloud computing is a model for enabling convenient, on-demand network access
to a shared pool of configurable computing resources (such as networks, servers,
storage, applications, and services) that can be rapidly provisioned and released
with minimal management effort or service provider interaction

Why Cloud Foundry?
Deploy in seconds not weeks or months
No need to talk to anyone else
Polyglot runtimes
 Java, Node.js, Ruby, Python, Go, PHP, …
Easily integrate internal and 3rd party services/APIs
Open Source runtime platform
IaaS independent – runs in the cloud or on-premise

8. © 2015 IBM Corporation8
Background
 Early 2011: Open Source effort initiated by VMware
 Focused on addressing the cloud market beyond IaaS
 April 2013: Pivotal created from EMC & VMware around SW and
OSS assets including Cloud Foundry, Rabbit, Spring, …
 November 2013: Pivotal CF, commercial version of Cloud Foundry
released
 February 2014: IBM announces BlueMix, making use of Cloud
Foundry
 2014 and beyond: Rapidly growing ecosystem of OpenSource
contributors, consulting companies & commercial, value-add ISVs

Experimental in nature
- Require rapid iteration
- Faster time to market
- May be decommissioned quickly
Are written in multiple languages
- Web: JavaScript, Ruby, Java, PHP
- Mobile: iOS, Android, SDK
Composed of Services
- Build using a composition model of
stitching capabilities together
- Capabilities often require time to test in
app beyond the scope of a free trial
Integrate with existing systems
- Data is often located in multiple places
(public, private, traditional data center)
- Existing systems may not scale at the
same the level of cloud applications
Cloud and Mobile Applications

TWILIO DEMO (ROB)
• Demo covers:
• Cloudfoundry concepts
• Userid, organisation, spaces, services, runtimes, routes
• Commandline and web interface
• Logging.

Key Concepts
 cf command line tool used to interact with the Cloud Foundry
environment, via the Cloud Controller component
 Buildpack a collection of code responsible for transforming
pushed application artifacts into a ready-to-run droplet, in a
process referred to as ‘staging’
 Droplet a package containing everything that is needed in order
to successfully run your application (e.g. JRE, Liberty, the
application itself) short of the Operating System
 Service the means of providing runtime dependencies needed
by an application e.g. a database
 Warden the containerization mechanism used to achieve
application isolation in the Cloud Foundry environment

Example Buildpack: WebSphere Liberty
 Based on community Java Buildpack
 Runs executable JAR files, web (WAR) and enterprise (EAR) applications,
and WebSphere Liberty ‘packaged servers’
 Adds an IBM JRE and, when needed, the WebSphere Liberty runtime
 For WAR and EAR files, generates the required server configuration to
match bound services and provides client binaries
 Loads into the server only what is needed for the provided application
 Pre-deployed in IBM Bluemix and Pivotal Web Services
 Available as custom buildpack:
https://github.com/cloudfoundry/ibm-websphere-liberty-buildpack

Service Integration with the Liberty buildpack
 IBM services
 SQLDB / dashDB
 Monitoring and Analytics service
 Auto-Scaling
 Single Sign On
 Data Cache
 Session Cache
 MQ Light
 Cloudant
 Third party/community services
 New Relic
 mysql / ClearDB
 Postgresql / ElephantSQL
 mongodb / MongoLab
• Information about bound services is
available in the VCAP_SERVICES
environment variable
• Some services are container managed
only (SessionCache)
• Some services can be either container
managed or application managed
(SQLDB)
• Some services contain multiple features
which can be separately enabled
(Monitoring and Analytics)
• Some services have local analogs
(SQLDB, mongo) and some do not
(Monitoring and Analytics)
• Services may require client driver JARs,
extension features (WXS ESA), Liberty
features, bootstrap.properties

Deploying Cloudfoundry onto an IaaS.
BOSH
BOSH Cloud Provider Interface
VMware
vSphere

29. © 2015 IBM Corporation29
BOSH
 Provisioning system for VMs used by CloudFoundry (and others)
 Release Engineering, deployment, lifecycle management
 Monitoring, failure recovery, updates
 Cloud Provider Interface abstracts details of the IaaS layer.
 Helps with
 Packaging up a myriad dependencies at defined levels.
 Consistency between Staging and production environments.
 How?
 Stemcells package up OS tailored for each combination of VM Type and IaaS
 Release is a back of configuration and software that installs on top of a stemcell.
 Director manages deployments.
 Bosh CLI.
