Agenda
• A Quick Analogy
• Cloud Computing – An Inevitable Shift
• What does “Cloud” mean to developers?
– IaaS vs. PaaS vs. SaaS
• Clouds: Public or Private?
• Getting Started

Please feel free to comment, argue, disagree

A Quick Lesson from History
• When important paradigm shifts take place, it is hard to project
yourself into the future…
• But once you sit “on the other side” of the shift, the
changes it brought with it seem obvious
– Did someone/your kids ever ask you why phones
used to have a cord?

• What could be the impact of Cloud Computing on IT?
And on developers’ jobs?
Let’s go through a story you probably know very well…


The first electricity consumers/producers
• During the 19th century, the first electrical generators
appeared
• Some companies set up their own generators for their
own use
– Complex, fragile, very costly
– Absolutely not accessible
to the mass market


Not as simple as it seems…
• Very costly
• No standards
– AC? DC?
– What frequency?
– 110V, 220V, 230V, 240V, other?
– Plug? What plug?
– Redundancy? SLA?

What is the state of IT today?

Flashback
Today’s IT feels very much like electrical generators from
the 19th century

Could IT evolve in a similar fashion?


The Cloud Revolution has started
• In 2006, Amazon announces AWS
– Thanks Jeff
– ~Doubling every year
• Today, many traditional providers are being “cloudified”
– Hosting providers  IaaS providers
– Middleware vendors  PaaS providers
– ISVs  SaaS


The growth of data centers

The cloud will do to IT,
what electricity has done to the industry
-
“If you don’t like change,
you are going to like irrelevance even less.”
-- Gen. Erik Shineski

Fine…
But what does it mean to me, as a software developer?!?

1st decision: IaaS, SaaS or PaaS?
IaaS SaaS
PaaS
Juggle with Accept the
Flexible
technologies constraints


IaaS
• AWS – the most popular example
• Server Lego blocks – VM, storage, IP, etc.
• Development environment:
– “Give me a server, an OS, a virtualization layer, an application
server, a firewall, a database, I’ll deal with it! And patch it. And
monitor it. And…”
– Flexible but cOmpLiCaTed
• User point of view
– Custom systems and environments


IaaS – Congratulations!

“Great” news: you have now become responsible for the data-center!

IaaS – Consequences
 Directly managing your IaaS resources provides you
with resource elasticity (CAPEX-free), but…
 The amount of soft-IT typically required to do so is …
higher!
– All of the traditional IT activities remain
(maintain/patch/monitor OS+JVM+AS+DB++, etc.)
– + cloud-specific items: elasticity/security/automation

• My advice? Move on…


SaaS
• SalesForce.com, Zendesk, NetSuite, etc.
• Development environment
– Rigid – mostly through CONFIGURATION
– When available “development” takes place within the SaaS
itself
– Standard applications
– Very fast bootstrap
– Most of the time, lock-in is
very high


PaaS
• Development environment
– “Give me my typical development environment and
manage everything else for me – servers,
scalability, failover, backups, etc.”
– Custom applications

(Lots of different philosophies though!)

PaaS – the new platform for developers
• Applications and data are at the center of your world!
– Forget about servers, VMs, load-balancers, etc.

• Cloud concepts are applied to applications as first
class citizens
– On-demand, pay-as-you-go, elasticity, etc.
– No need to handle updates, patches, scalability, failover, etc.

This is a Service, not just some Software!

One word of caution…
• Could I please get a Private PaaS?
– Sure! We can also sell you a private jet!
– Very tempting! All of the advantages but no decision about the cloud is needed!
And I’ll be able to customize it!

• Yes, but…
– A great part of the value from a PaaS comes from the S: SERVICE
• With a public PaaS, you are outsourcing your Operations & DevOps
– With a Private PaaS you’ll get to improve the interface between DEV and IT
compared to traditional middleware, but … you remain in charge of all operations!
– And remember: Customization is the root of all evil!

• LoseIt! • LoseIt! – Reality

• Mobile Application • 4 employees total

• >12 million users • 2 developers

• >25’000 tx/minute • 2 marketing

• Real-time activity monitoring • 0 IT/operations

• Several releases a week •  4 employees

Conclusion
• Need for new data and applications is going to explode!

• It will become key to value failure and increase productivity

• New tools and processes are needed to achieve this

• PaaS is the new platform for developers

• The future is now!

32 32

Getting Started
• Get familiar with PaaS as a concept
• Try out two or three with simple examples
– CloudBees, Google App Engine, Amazon EB…
• Understand Cloud Infrastructure (IaaS) but don’t get
bogged down with the details
• Understand where your real value-add lies
• Think about the entire PaaS dev-build-test-deploy cycle


PaaS Vendors have Strengths &
Weaknesses
• PHP? Start with Amazon ElasticBeanstalk…
• Ruby/Rails? Look at Heroku…
• Python? Try Google App Engine…
• Java/JVM? Check out CloudBees…
• For RDBMS, MySQL is obvious choice but Amazon
RDS offers additional options
• For CouchDB or Mongo, check out specialist service
providers


Mobile + PaaS = A Great Fit
