The document provides an overview of cloud computing and the Cloud Foundry platform. It discusses the evolution of cloud architectures including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It introduces Cloud Foundry as an open source PaaS and discusses its key features like portability across clouds, choice of frameworks and services, and enabling developer agility. The document also covers Cloud Foundry's architecture, community project, and major use cases.

4. Accelerando / Singularity, in a Galaxy far far away
§ Even if we automate ourselves out of a job every 10 years
§ ...I don’t think the singularity is near!
4

5. Moore's Law is for Hardware Only
§ Does not apply to software
§ Productivity gains not keeping up with hardware and bandwidth
§ Writing software is hard, painful, and still very much a craft

6. Predictions
“The future is already here
— it's just not very evenly
distributed”
William Gibson

7. Architecture Changes: 60’s Mainframe

8. Architecture Changes: 80’s Client-Server

9. Architecture Changes: 90’s Web

10. Architecture Changes: 2010’s Cloud, HTML5, Mobile

11. Back to Client Server: Groovy Baby!

12. What is Cloud Computing?
Cloud According to my daughter Eliette
12

13. Cloud Stack - Classic Pyramid
Software
As A Service
Platform As A Service
Infrastructure As A Service
13

14. Cloud Stack - By Value
Software
As A Service
Platform As A Service
Infrastructure
As A Service
14

15. Cloud Stack - History
§ What does cloud mean, 4 main angles
• Software 1994 Netscape
• Infrastructure 2002 Amazon AWS
• Platform 2008 Google
• Development now!
§ Industrialization of hardware and
software infrastructure
like electricity beginning of 20th century
§ But software development itself is moving towards craftmanship
15

16. Cloud started at Consumer websites solving their needs
• Google, Amazon, Yahoo, Facebook, Twitter
• Large Data Sets
• Storage Capacity growing faster than Moore’s Law
• Fast Networks
• Vertical -> Horizontal scalability
• Open Source Software
• Virtualization
• Cloud is a productization of these infrastructures
• Public Clouds Services: Google, Amazon
• Open Source Software: Hadoop, Eucalyptus, Ubuntu, Cloud Foundry

17. Infrastructure
17

18. IaaS/Virtualization getting mainstream
§ AWS, Joyent, Rackspace,...
§ Open Source projects: OpenStack, DeltaCloud, Eucalyptus
§ Automation: Chef, Juju, Cloud Foundry BOSH
§ Standardization? DMTF
§ Inside the Firewall, Virtualization: VMware, Microsoft, Xen, KVM
§ 50% of workloads are virtualized
§ Easy to provision, manage instance...BUT
§ Still need to manage backups, software stacks, monitor, upgrades
18

19. With Infrastructure, you still need to build your own platform
§ Need to build a distributed platform on top of you infrastructure
§ Story of the AWS meltdown from last summer
• http://blog.reddit.com/2011/03/why-reddit-was-down-for-6-of-last-24.html
• http://www.readwriteweb.com/cloud/2010/12/chaos-monkey-how-netflix-uses.php
• http://news.ycombinator.com/item?id=2477296
• http://stu.mp/2011/04/the-cloud-is-not-a-silver-bullet.html
§ Twilio, Smugmug, SimpleGeo survived it because they built their own
distributed platform on top of IaaS
§ Enterprise customers want to consider Infrastructure like CDNs
• Multi Cloud usage
• Based on Open Source de facto standards, or full standards whenever that happens
19

20. Platforms
20

21. Platforms
§ Raise the Unit of currency to be application & services instead of
infrastructure
§ Google App Engine, Cloud Foundry, Heroku, CloudBees, Amazon Elastic
Beanstalk, Microsoft Azure, AppFog
§ Single or a few languages, services
§ Start of Multi language Polyglot platforms
§ Enabler for Agile Developers -> Create Business value faster
§ Lack of standards: risk, vendor lock-in
§ Enterprise needs:
• Control, customizability
• Private/Hybrid Cloud
21

22. Agile Development Processes

23. Agility as a survival skill
§ Consumer software is becoming like fashion
• Phone apps, social apps, short lifetime, fast lifecycles
• A/B testing
§ Enterprise
• Clay shirky situational apps
§ Kent Beck, Usenix 2011 Talk, “Software G-Forces: the effects of acceleration”
change in software process when frequency grows
§ Cloud Platforms enables an Agile culture, driver for innovation
• Scalability is built in the platforms
• Can iterate faster

24. 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!

26. Lessons for
Developers
26

27. Predictions
• Software is becoming like fashion, design rules
• Welcome to Babel, use the best tool for the job, embrace
multiple language & heterogeneity
• Our jobs will change, build yourself out of your current job
• Sysadmin jobs will morph, there will be less of them
• Many opportunities open when you embrace change
27

28. Things to forget
• First normal form
• Waterfall model
• Single server deployment
• Single language skill
• Build everything from scratch
• Build custom infrastructure
28

29. Things to learn
• Agile
• Take risks, fail often, fail fast and learn
• API Design: create the API first
• UI Design, Javacript, HTML5, CSS3
• A/B Testing
• Open Source, Open Standards
• Architecture, Distributed Computing (CAP theorem, 8 fallacies)
• Cloud Platforms and APIs
• Multiple types of languages (imperative, object, functional, logic)
• Ability to encapsulate domain knowledge in a DSL
• Build on the shoulders of giants: reuse, REST APIs
• Pick your battles, choose what you need to build yourself to add
value
• Learn to live in a box (embrace platform limitations) to think
outside the box
• Use an App Store for distribution
29

30. The Open
Platform as a Service
Deploy and scale applications in
seconds, without locking yourself into a
single cloud
30

31. “I just want to deploy my code…”
31

32. What if…
target
<any
cloud>
push
<my
app>
bind
<my
services>
instances
<my
app>
+100
32

33. 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

35. 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

54. 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
