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


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

TWILIO DEMO (ROB)

• Demo covers:

• Cloudfoundry concepts

• Userid, organisation, spaces, services, runtimes, routes

• Commandline and web interface

• Logging.


CLOUD FOUNDRY

ARCHITECTURE (DAVID)


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


Cloud Foundry Architecture


IBM Confidential June 7, 2013

Application Push

cf push {APPNAME}


Application Staging


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:

• 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

Bluemix Hybrid Cloud


Deploying Cloudfoundry onto an IaaS.

BOSH

BOSH Cloud Provider Interface

VMware

vSphere


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.
