This document summarizes a presentation on how Java technology can help organizations meet the challenges of building e-applications and becoming e-organizations. The presentation discusses the key requirements of e-applications including business models, information management, software engineering, integration, security and infrastructure challenges. It then outlines how Java addresses these challenges through its support for mobile code, network security, components and dynamic applications. The presentation concludes by discussing Java Enterprise Edition and the iPlanet product line.

A Paradigm Shift

•
Internet is “the single most important event since the industrial
revolution.” (Jack Welch, Chairman – General Electric)
The revolution in information technology has altered the structure of
American Economy. (Alan Greenspan, Chairman. US Federal Reserve)
.. A new era of computing .. new levels of enablement to humanity … its
impact on humanity is comparable to invention of telephone and air travel.
(Rajeev Arora, “Using Enterprise Java”, 1996)

11. Summary of the Business Model Challenge
• Changes in the role of the Info-mediary
– New ways of creating existing relationships => New infomediaries
– Creation of new relationships
– New ways of interacting in existing relationships
– Security and trust management in relationships which exist
in virtual communities that cut across physical trust
boundaries
• Differentiators
– Ability to introduce new services for your captive
audience at minimum cost and lead-time
2000 ACS Annual Branch Conference
IT Trends

12. The Information Challenge
• The e-information model
– Self-describing data to achieve interoperability
• Syntax and semantics (syntax is easy, semantics hard)
– Structured and unstructured
– OO and relational
• Dynamic manipulation of self-describing data
– Discovery and binding
– Manipulation: Presentation and other operations on
data/objects
• Distributed Databases and Transactions
– Database Updates through multiple n-tier servers
– Replication and Cache Management
2000 ACS Annual Branch Conference
IT Trends

13. The Software Engineering Challenge
• Rapid Application Development
– Faster time-to-market is the winner
– Rely on rich library of “ready-to-use”components
• Developing substantially more complex software – reliably
– Managing increased complexity and size
– OO does to system design what structured programming did to
coding
• Extensibility
– Ability to “multi-purpose” an existing piece of software
• Cross-platform
– Network centric computing requires software to be “node”
independent => RM ODP Transparencies
2000 ACS Annual Branch Conference
IT Trends

14. The Integration Challenge
• Ability to integrate with any application
anywhere
• What do we mean by integration
– Exchange data
– Invoke operations on data (manipulation)
– Security integration (authentication and
authorization)
– Any time: Real-time or Deferred.
• Static and dynamic integration
2000 ACS Annual Branch Conference
IT Trends

15. The Security Challenge
• Network Security
– Platform and network security are inter-related
– A “weak” host anywhere on the Internet can be a
hazard to you
• Managing Trust
– Who you trust for what => Authentication and
authorization (among other security functions)
• Inter-operable security
– Ability to manage trust “interoperably”: across virtual
communities.
– Will virtual communities become the “real”
communities?
2000 ACS Annual Branch Conference
IT Trends

16. The Infrastructure Challenge
• Performance and Response Time
• High-availability: 24x7
– Ability to carry out hardware and software
outages with application outages
• Scalability
– Ability to start very small and grow without
changes to the logical architecture of the
“system”
2000 ACS Annual Branch Conference
IT Trends

17. Summary of Challenges
• Why challenges and not architecture
requirements?
– A mix of business re-engineering, technology and
processes is required; in addition to education of the
participants
– Technology standards and marketplace still in the
process of maturing
• How Java technology meets some key technology
challenges
– Information, Integration, Software Engineering and
Security

18. Java Technology:
Strategic Benefits from
Network-centric Innovation
2000 ACS Annual Branch Conference

19. Why Java?
• The best sliced bread?
• Best OO Language?
• First-ever cross-platform development tool?
• First-ever write-once run anywhere solution?
• Quotes: Java advocates
• Network is the computer, (Java is the language).
• Cross platform development “nirvana”.
• Most secure platform for Internet applications.
• Quotes: Java Critics
• Wake me up when Java hasn’t changed for 3 months!
• Java is a science experiment out of control.
• Java virus!

and remote
deployment
locations.
• Resources may be
secured by name and
operations.
• Policy can be
centrally
administered within
an enterprise.

24. What’s Inside a Component?
• Structured metadata used by the system
to manage the component.
• Structured metadata used by component
user to compose new applications.
Component-specific data (Code, data,
HTML pages, scripts, images...)
One or more objects implementing the
component’s interfaces (including
component management)
Required interfaces (Application, Configuration)
Standard interfaces (Infrastructure, Management)
Discovery interfaces (Advertise Services)
