Objective
 Can the power of Java be leveraged in the Enterprise ?
 What are the needs of enterprise-wide computing and how does Java
support ?
 What is a Java-based Enterprise System architecture like ?
3
What is Java ?
 Java - The new programming language developed by Sun Microsystems
in 1991.
 Originally called Oak by James Gosling, one of the inventors of the Java
Language.
 Java -The name that survived a patent search
 Java Authors: James , Arthur Van , and others
 Java is really “C++ -- ++ “
 Originally created for consumer electronics (TV, VCR, Freeze, Washing
Machine, Mobile Phone).
 Java - CPU Independent language
 Internet and Web was just emerging, so Sun turned it into a language of
Internet Programming.
 It allows you to publish a webpage with Java code in it.
4
Java (and .NET) is extraordinarily popular . . .. . . especially
for medium-size and large firms.
5
The Journey…
 1995 - Java was released by Sun Microsystems
 1991 –James Gosling names new language ‘Oak’
 1993 –Public Internet
 1995 –Name changes from Oak to Java.
 1996 –First JavaOne Developer Conference.
 1999 –J2EE beta software is released.
 2002 –J2EE SDK downloads reach 2 million.
 2005 –~4.5 million developers use Java technology.
 2006 –Most of Java is released under open source.
 2010 –Oracle completes acquisition of Sun Microsystems.
6
The invention of WWW started a meteoric change in IT
application development
 It caught everyone by surprise: technology vendors, businesses,
developers
– Remember $150 per hour HTML developers: “&*@# !!!.”
– Remember cgi-bin:
– Remember the end of brick-and-mortar companies
– Remember the stock market
 Sun Microsystems moved quickly to take advantage by selling servers
and offering Java as the platform for Web development.
– Most other software vendors, such as Microsoft, were caught off
guard, and Java became the de facto Internet development
standard for enterprise Web application development. Along with
supporting technologies such as HTML and JavaScript.
Other vendors followed with alternative technology such as Adobe
ColdFusion, Microsoft Active Server Pages (ASP), and others
7
Write once, run anywhere …
 Simple, object-oriented, and
familiar C/C++ like notation
 Robust and secure
 No pointers, automatic garbage
collection
 Architecture-neutral and portable
 Byte code running on virtual
machine
 High performance
 Native code when possible
 Interpreted, threaded, and
dynamic
 Class libraries
8
 J2EE
– Frameworks galore
– JBoss Hibernate
– Spring Source
– JSRs galore Servlets, JSP,
etc.
 Development tools galore
 Runtime containers (app servers)
galore
– New programming languages
Groovy/Grails, JRuby, Scala
Enterprises develop business applications to enable
business capabilities and serve customers directly
9
Does popularity of Java, mean it is the best choice for
business application development in 2011 and beyond?
10
The future of Java depends on how well the platform meets
the changing needs of business and IT
 “We can’t keep up with the changes.”
 “How do we redesign our web application?”
 “The business doesn’t know what it wants.”
 “The business keeps changing its mind.”
 “Will our architecture support the business requirements?”
 “Results have improved after we adopted Agile methods, but not
enough.”
 “We have to improve the user experience.”
 “Change is continuous.”
11
Wildly desirable business applications must strike the right
balance among these seven qualities
12
Quality
What it means
Experience
Users’ perceptions of the usefulness, usability, and desirability of the application
Availability
The readiness of an application to perform its functions when needed
Performance
The speed with which an application performs a function to meet business and user
expectations
Security
Supports the security properties of confidentiality, integrity, authentication,
authorization, and non repudiation
Economy
Minimize the cost to build, operate, and change an application without comprising its
business value
Scalability
Handle increasing or decreasing volumes of transactions, services, and data
Adaptability
The ease with which an application can be changed or extended
Old ways haven’t been working so well…
Standish Group
CHAOS Summary
2009 report states …
Two-thirds (68%) of projects
failed
or
were challenged in some
way.
13
32% of projects succeeded
44% were challenged
24% failed
A programming language cannot make it all…!!
 Programming languages are not the only way to develop business applications.
– Business process management (BPM)
– Business rules management systems (BRMS)
– Business intelligence (BI)
– Business event processing (complex event processing CEP*)
– Content management and collaboration accelerators
– Platform-as-a-service
 Newer programming languages are designed to make certain apps easier.
– Ruby on Rails, web2py, and many others
– Many of these alternatives are built on-top of Java platform -cool
 Excellent productivity-focused app dev tools have existed for years.
– 4GLs
– Many new players such as salesforce.com, WaveMaker Software, and many, many
others

What do we need for an Enterprise

A combination of tools and platforms is necessary

SOA Value Proposition – Value for IT
IT Aspects – why should you care about SOA?
20
Revenue
Create new routes to market, new value from existing
systems
Flexibility
Develop flexible business models enabled by increased
granularity of processes (“services”)
Speed
Combine and reuse pre-built service components for rapid
application development and deployment in response to
market change
Efficiency
Integrate historically separate systems, facilitate mergers
and acquisitions of enterprises
Reduce cycle times and costs for external business
partners by moving from manual to automated
transactions
Service
Offer new services to customers without having to worry
about the underlying IT infrastructure
Cost
Eliminate duplicate systems, build once and leverage
Risk
Improve visibility into business operations
A Services Oriented Architecture (SOA) - Expose key IT
capabilities and make them available in new ways
A service-oriented architecture (SOA)
is an architectural framework that takes
business applications…
…and breaks them down into
services…

Cloud is a shift in the consumption and delivery of IT with the goal of
simplifying to manage complexity more effectively.
 Cloud is:
– A new consumption and delivery model
 Cloud addresses:
– Cost reduction
– Scale
– Utilization
– Self-service
– IT agility, flexibility and delivery of value
 Cloud represents:
– The industrialization of delivery for IT supported services
 Cloud includes:
– Deployment models: public, private, hybrid
– Delivery models: Infrastructure as a Service (IaaS), Platform as a
Service (PaaS), Software as a Service (SaaS) and Business
Process as a Service
– Focus on the End user – self service delivery

Recommendations
 If you are using Java successfully, then there is no reason to abandon the ship.
 Investigate every alternative platform and how you can use them to get faster and better
satisfy both the business and users.
 You can continue to be largely a Java shop but start to bolt on other platforms such as
BPM to deliver on new requirements.
 Set an architectural path toward more productive application development tools.
 Start by identifying the fastest-changing apps.
– Choose platforms that will fulfill that change faster, for example. Rapid application
development tools such as application development productivity platforms (ADPP)
– Business process management, business rules, business events
– Dynamic Web frameworks
 Do not think how you can develop Java applications faster. Instead, think how you
can develop applications faster. This opens your mind to look outside Java to these
alternatives.
 There is no one solution that will satisfy all your use cases. But, don’t make Java the
automatic default for custom-developed apps .
– Instead create a “Should this be a Java app?” checklist.
