Agenda

•A changing world•The role of Spring•Where next?


Agenda



Enterprise Java has changed dramatically

• Profound change in technology• Change in the business

landscape


Forces driving change

• Failure of “Old J2EE” (EJB/heavyweight model)

• Developers want simpler solutions– More compatible with agile processes

• Global recession– Companies want to lower costs– Drives desire for simplicity throughout

“Lean Software”

• Forrester defines “lean software” as an approach to building, delivering, and running software that values fit-to-purpose, simplicity, and time to results above all

• Lean approaches minimize complexity, startup time, resource usage and avoid features not essential for the application’s business purpose

Source: Forrester: Lean Software Is Agile, Fit-To-Purpose, & Efficient


What drives lean software?

YOU!!


Developer empowerment

• Over the last 10 years we’ve seen growing developer empowerment

• Why?– Because developers saved the enterprise

Java platform from its initial failure– Faster change forces managers to rely more

on developers


Developers have enormous power today

• We live in great times for developers

• Ability to make a difference in a deep way

• Open source allows participation in shaping, not only using, technology


Today, Developer choices matter


Silicon Valley no longer makes all the rules

• Opportunity for Japanese developers to help shape the future


Innovation from the community has made decisive change

Old leaders• IBM• BEA• …

Today’s leaders setting the agenda• Spring• Hibernate• Ruby on Rails• Django• Grails• Eclipse ecosystem

OPEN SOURCE IS THE ULTIMATE EXPRESSION OF DEVELOPER POWER


Open Source is not just cheaper: It’s naturally simpler


Move toward simpler, practical solutions

Yesterday Today

Bloated one size fits all product from mega vendor

Best of breed point solutions

Closed source Open source

Software that works best on Powerpoint slides

Software championed by developers

Grand SOA vision Practical authoring of services


Strong implications for Java infrastructure

• The monolithic application server is out of step with the times

RIP the Traditional Java EE Application Server

• The age of the traditional application server is over

• Has been living on borrowed time

• Recession is the final blow

Why?

• In a recession, people won’t pay for features they don’t want or need

• Move from one size fits all to specialized workloads

• Virtualization/cloud drives need for lightweight products

• Productivity challenges to enterprise Java put spotlight on complexity

• Emergence of new programming model, decoupled from server has freed applications


Borrowed time has run out

• “Develop on Tomcat/run on WebSphere” just a transitional phase

• Heavyweight application server does not meet todays market needs

Develop on Tomcat, run on WebSphere

100% WebSphere

100% Tomcat


Evidence: Tomcat groundswell

• By far the most popular application server today worldwide, in development and production

• Used by around 70% of organizations developing Java web applications

• Represents developer-driven switch away from complexity


Drives business change, too

• Can the old market players respond?

NO!!


What happens next?

• Possible IBM/Sun merger?–So the parents of enterprise Java

complexity finally get married–Neither has set the agenda for

enterprise Java for years


What happens next?

• Java EE 6?– Initially promising but flubbed opportunity to

make Java EE relevant

• Repeats old mistakes– Ties programming model to platform once

more• Even “web profile” tied to EJB and other APIs

– Again, introduces unproven concepts into specifications (JSR 299)

• Questionable if it will be widely adopted


Agenda



What is Spring?

• Spring is the de facto standard for POJO programming

• Runs in any environment• Relevant tomorrow as well as today

• A dependable part of a changing world

Gartner: Trends in Platform Middleware: Disruption is in Sight

The convergence of technology trends will yield a new breed of platform middleware products that will be only partially compatible with the current generation…

ForresterA majority of [enterprise Java] users

interviewed by Forrester use Spring

InformationWeek: Raven ZacharyThe adoption of Tomcat reflects

the Java programmers' preference for lighter, simpler technologies.

Japan is country with least Spring adoption


Trends in Platform Middleware: Disruption is in Sight

• Spring can help provide stability as applications and technologies evolve

Meanwhile, a new generation of Java-based, non-Java-EE compliant platforms addressing XTP requirements has selected Spring as itsprogramming model. - Gartner Group, September 2007

Spring can potentially support any container (Java EE or not), thus enabling a good degree of application portability across different platforms.


Agenda



Unfinished business

• Spring stands for elimination of enterprise Java complexity

• Much achieved, but much still to do…


An important step on the road: More still to do

• Escape from the monolithic application server is a big step toward addressing the remaining challenges of enterprise Java

• Still too much complexity in enterprise Java development/deployment...


What’s still to do

• Challengers– Ruby on Rails– Django– ...– New Zend server

• Modern enterprise Java is way better than 5 years ago

• But…it’s still too hard to…– Start a new Java

project– Obtain and

integrate all the necessary software


Why? No one cares about the whole picture of Java productivity


SpringSource and the application lifecycle

• SpringSource is focused on tackling the whole problem

• Coherent vision for all stages of the lifecycle

• Building on open source and the lessons developers have learnt


Our objective: Complete infrastructure for building, running and managing Java applications

SpringSource actions

• This is…–Why we became the leading

contributors to Tomcat–Why we invest in the SpringSource

Tool Suite• Eclipse distribution

–Why we will provide a cloud offering


SOME OF OUR INITIATIVES…


Build: Simplifying how you author projects: RAD initiatives

• Rails introduced some great ideas but its limitations are more and more apparent– Struggles with enterprise scale/complexity– New, alien stack disruptive to introduce

• Grails offers the same key benefits, but based on the power of enterprise Java and Spring

• Stay tuned for additional productivity technologies from SpringSource

Build: Grails tackles the 800 pound gorilla

• Learns from Ruby on Rails• Productivity of the

number one dynamic language on the JVM (Groovy)

• Built on Spring and supported by SpringSource

Run/Manage: SpringSource’s server strategy

• Four key advantages– An independent vendor– No need to protect a revenue stream on a

product people don’t want– Leaders in the movement that reclaimed

enterprise Java for developers, not defenders of the status quo

– Building on de facto standard programming model that spans more than traditional application server model (Spring), and the #1 server (Tomcat)


SpringSource’s server strategy

• Recognizes the realities in the market• Embraces, rather than fights, developer

choice– No unnecessary complexity

• Provides developers with the features they want with the operational features enterprises need



• tc Server is a solution for WAR-based web applications which you’d already like to run on Tomcat

• dm Server is targeted at next-generation, modular applications• The best place to do OSGi on the

server side• Not limited to web workloads



• Combines developer-driven simplicity of open source with enterprise grade management needed in the data center

• Consistent management fabric spans both servers


Why do people choose Tomcat?

• Fast• Robust• Better development experience than

Java EE servers• Spring’s abstraction and portability

allows them to choose the most appropriate server, removing the API barrier to Tomcat adoption


SpringSource tc Server

• Addresses Tomcat’s limitations in the data center

• The Tomcat you know, the enterprise capabilities you need• Enhanced operational management

capabilities • Enterprise-level mission-critical support• Significantly lower cost than legacy app.

servers• Powerful, yet lightweight solution


Who should use tc Server?


It’s clear what must be done

• Enterprise Java must get simpler• Must offer a more joined-up

experience• Must advance into the new world of

cloud, virtualization and high developer productivity expectations

• Watch for major news from SpringSource in next few weeks


The future is exciting for Java developers!

• The age of the traditional application server is over

• An important step towards making Java more competitive

• Open source will continue to drive innovation

• The age of Lean Java has begun
