IBM Rational Enterprise Modernisation

There are Challenges…
Dated environment, unappealing to new
talent, not designed for modern applications
Decades old applications with text-based UIs
and brittle architecture
3
Isolated teams, using disjointed tools and
processes
Deploying modern complex applications
requires coordination of many tasks and
offers many opportunities for failure

IT & Business Executive Pressures
Bottom line: IT flexibility enables business flexibility

Rational Application Modernisation Solutions
Aimed to Help Customers with:
Escalating Costs – Spend too much time and resource on maintaining old applications (up to 80% of IT budget is
maintenance)
Wide Spread Need - The pain it causes exists in all sizes of company and in all marketplaces
Proven, Available Solutions - whichever direction Modernisation takes you.
Real Solutions
The customer can do two things which we will discount:
•
Nothing (and pay for increased costs) and buy packages or outsource totally
There are four other Options which need to be discussed in detail:
•
“Update” – Improve the user experience using tools like HATS or Portal
•
“Optimise” – Make it easier (and cheaper) to maintain the back-end applications. Leads to Asset
Identification and reuse, then to SOA and WebSphere Process Server.
•
“Convert” – Move the existing applications ‘as is’ to a new platform using automated tooling
•
..and “Re-write” – Start again but making use of the existing assets and extracted designs. Move to a ‘write
once, use many times’ environment, increasing quality and lowering costs
Every Customer is Different
Assess Priorities
•
May be necessary to have a short term solution whilst the strategic approach is defined and implemented
•
Major element of timing – customers often have to commit to licence and contract renewals at fixed dates,
leaving them no option but to continue paying excessive charges

Revitalize
Applications
Rational Host Access Transformation Services
Achieve fast ROI with low risk
Quickly and easily transform green screen
applications to Web services, Web, Mobile,
Portal and rich client interfaces
Low cost and low risk: No need to rewrite or
refactor existing applications and built on
open, proven platforms and technologies
Increase productivity and reduce training
costs and data entry errors with workflow
and navigation improvements
Integrate host business processes and data
with other web, portal, mobile, and rich
client applications
Packaging:
Rational HATS for Multiplatforms
HATS for 5250 Applications on Multiplatforms
HATS for 5250 Applications on IBM i
HATS is also included as a component of
Rational Host Integration Solution (HIS)

Host Access Transformation Services (HATS)
Rich Client
• Integration at the
desktop with other
Eclipse-based
applications
• Client side
processing
• Rich set of user
interface widgets
• Supports Lotus
Expeditor
deployment
Browser
• Zero footprint
• Pure HTML
• Access through
your favorite
browser, including
Internet Explorer
and Firefox.
• Web 2.0
Portal
• Integration at the
glass
• Cooperative portlet
support
• JSR 168 compliant
Mobile
• Access host
applications from
mobile devices
• Now includes iPad
Web Services
• Build self-service
transactions
• Expose host
business processes
as Web Services
• Provide controlled
access to vital host
applications and
host data.
Quick ROI : Host applications can be quickly deployed with a new user interface
Low cost : No need to rewrite application
Low risk : Leverage open, proven platforms and technologies
Increase productivity and reduce training costs
Improving work flow from multiple applications
Provides integration of host business processes and data with other Web, portal, and rich client applications

What’s now in HATS
Web 2.0
Dojo
•
HATS Dojo widgets
•
Transform for Dojo editing
•
Dojo for IOs
New templates
RESTful web services
JSR286 Portlet support
iPad support
Support for the latest runtimes
Support for the latest development tools
And more….

Web 2.0: Templates
Research, industry, and medical
Benefit: Modern look and feel- tabs, menus, highlighting, fading, rounded corners
17
iPad Support
iPad has been added to the growing line
up of mobile devices that HATS supports
Windows Mobile devices
iPod Touch
iPhone
iPad
The larger display size of iPad works
especially well for customer facing roles
Mobile devices open up possibilities:
An employee on the department store floor
needs to check stock in the warehouse and
make an order
A distributor of products to car dealers needs to
track product availability and order products
while at the dealer
Hospital personnel need to take inventory across
a large campus
Service personnel need to order products and
mark work complete
