Introduction
A majority of organizations around the world are
undertaking application modernization owing to several
challenges - changing business demands and technology
challenges are forcing organizations to improve operational
efficiency of applications, while managing risk; organizations
are facing complexities of rising cost & complexity
of maintenance with users clamoring for better applications
& newer features on one hand, while budget constraints
do not allow them to do much about it on the other;
organizations are not sure whether internal IT teams
are geared to be able to expedite application modernization.
Critical application knowledge resides with a few
people and there is little or poor documentation.
And most importantly - mature systems are sitting
on older technologies, while competitors are zooming
in with great architectures and easy to use modern
front-ends.
Migration, as part of application modernization,
leverages the current business model and the features
of the application to move towards enhancement in
a cost-effective manner. Quintegra can provide migration
services that cater to varied platforms. We bring
in our tools and expertise to make a smooth transition.
Offering
Quintegra’s approach to migration is to use
software based automation to the maximum, ensuring
the focus shifts from technology to the business processes
present in the system.
This is made possible by our emphasis on R&D
which has yielded an ability to analyze the existing
source code by means of tools, and our own homegrown
migration blueprints which allows for designing using
UML and BPMN notations. Our migration blueprints also
support automatic generation of controller and class
code along with database schema. The usage of industry
standards for the visual modeling allows business
analysts to focus on the business process flow while
the output of this modeling is fed to the tool for
code generation.
Quintegra offers end-to-end migration services, starting
from application analysis, target environment selection,
strategy definition, to implementation & support.
Our offerings for migration are as follows:
Porting
This primarily deals with enhancements made to the
technical environment of the existing legacy system.
The enhancements could involve changing the hardware
platform, underlying language / application, database
and/or operating system on which the system is currently
deployed. The other technical aspects of the system
such as data management mechanisms and application
design are either not changed or changed very minimally.
Conversion
Programming language conversion or the data management
technology is what typically constitutes the migration.
Changes are made in the various parts of the application
for data access and storage in the new data management
environment. Quintegra performs multiple types of
conversions including conversion of application programs
within the same platform - from one dialect of the
programming language to another and from one language
to another; conversion of database and data servers;
and conversion of application programs and data across
platforms. Version upgrades form a part of our conversion
services.
Extension
Extension is more of a ‘quick-fix’ solution;
in that it does not address the core problems in the
application but seeks to merely replace certain functionality,
such as the User Interface, to provide users with
a modern look & feel. For example, the Mainframe
is treated as a black-box exposing some or all of
its functionality by means of web services where applicable,
and the new screens are developed to be able to ‘talk’
to the Mainframe. Quintegra creates a new user interface
layer (screens) that connects to the Mainframe. The
green screen terminal is thus transplanted into a
web environment, delivering rich user experience through
the use of web technology. The Mainframe however continues
to exist as it is.
Integration
The EAI offering addresses challenges caused by disparate
systems on heterogeneous technologies, data management
and duplication challenges in the organization. Quintegra
offers a host of services from consulting to integration,
& porting/migration services for EAI products.
Our approach offers the following benefits:
 |
Iterative
and incremental development approach to gain
early ROI |
|
Seamlessly
linking heterogeneous business applications
into one unified system |
|
Migrated
application integrated with other existing enterprise
applications |
|
Competency
in a variety of technologies such as Tibco,
Seebeyond, Vitria, WebMethods, MQSeries, BizTalk
and Web Services as well as custom solutions |
Quintegra offers valuable application migration services
where clients are satisfied with the functionality
of the existing system and not willing to change the
existing business process, but the existing application
technology platform is outdated and not meeting the
future business growth.
Quintegra can analyze the existing legacy application
functionality in detail, identify the target technology
platform and build the solution on the target platform
with the functionality of the existing application.
