<b> Introduction </ b>
Deploy to Companies Gaining a variety of software and hardware applications is a competitive advantage. The combination of rapid advances in IT and evolving business needs has contrasted the IT environment across the enterprise.
At one end there is an open architecture application that leverages the possibilities of the Internet, and at the other end a legacy closed-end legacy software company data still resident in legacy system estimates for some market research systems More than 70% of The business needs of tomorrow for managing and redeploying legacy systems is also a big challenge.
By this white paper, the effectiveness of problem management in the organization, existing legacy system.
<b> Legacy Applications </ b>
<b> Definitions </ b>
The traditional system is a large database of access for storing large amounts of data stored in the middle of the legacy database management system mainframe.
The economic implications of these systems have been developed. The functionality of these systems was evident at the time of installation. But as technology and business needs evolve, they are becoming complex and economically unsustainable.
As companies have invested considerable time and money in these systems, these investments can not simply be written down.
<b> Issues related to legacy applications </ b>
The current state of the legacy application features and maintenance related to several issues. Some of the typical challenges are listed below:
The internal, enterprise-wide use for legacy system platforms is as new as it is today. Most internal business logic.
These applications are not flexible. The announcement of modules that are not isolated is a key resource of business database logic consumption.
Lack of documentation and skilled workforce creates a holistic one rather than any change ad hoc process. This is an accident and failure prediction system.
Efforts to address these challenges are fragmentary and have limited impact. The combination of the new system and the modified old system eliminates the problem. The adoption of new technologies and languages is often done solely for the sake of technology. Finally, mobile devices such as new channels via the Apply to Delivery feature are a successful modernization heritage with the addition of different trading methods.
<b> Legacy Application Benefits </ b>
Agencies continue to use for a variety of reasons for legacy applications. Some of the benefits perceived by an organization are:
Those who developed legacy systems are an important application of the mission.
Many users use the system. They are very familiar with the functionality of the application, including appearance and quality. They also fully understand the strengths and limitations of the system.
Legacy systems, such as underlying hardware and software, are always very reliable. The application itself has evolved over the decades and works very well as expected.
These factors contribute to the continued use of legacy systems. However, effective modernization of these legacy systems places a minimal burden on extracting such benefits.
<b> Changes in business requirements and legacy applications </ b>
The economic and political conditions of recent years have brought about some new challenges for technology organizations.
The time to market is down. Six months project cycle of 18 months project cycle from the organization.
New products and services are being introduced one after another.
With globalization and deregulation, the need for a flexible system that can be synchronized with the rapid shift in business has become important.
We expect the right services for organizational mapping cost management.
These dynamic considerations make it essential for organizations to assess the financial viability of the it portfolio, taking advantage of the language benefits of the new era,
Strategic issues to consider becoming a business leader go beyond legacy systems:
Total cost of ownership-
In general, the total cost of ownership (TCO) to keep a legacy system up and running can be very high compared to the cost of running a modern system.
The TCO of the system includes parts such as operation (hardware, system software), production support and application maintenance. The lines of code, the quality of the documentation, and how the application is configured directly affect the cost of the system.
According to industry experience, maintenance costs are tripled after legacy systems are converted. This is actually a new system that enables better structure, better, and optimized code.
productivity -
Traditional systems are typically deployed on mainframe platforms that are the basis of their stability, scalability, and reliability. It is possible that the approach should be recognized as a modernization heritage system.
The current symptoms are optimized, the existing system performance is enhanced, and the transition mainframe platform does not mean modernization heritage.
Flexibility-
We apply new technology as application component by conventional application of technology. However, the main loss of flexibility stems from the fact that the application is monolithic--a more multi-tiered architecture, with separate presentation and business logic, allows more flexibility, with changes coming soon. Can.
The strictness of the architecture favors some organizations to redesign traditional applications while maintaining the underlying platform and language
The transformed application makes for a multi-tiered, adaptive system allowing easy integration of new technologies.
Knowledge Availability-
Programmers skilled in COBOL, PL / 1, assembler and some other legacy languages are vanishing tribes. These programming languages are no longer taught in the computer science courses of schools and training institutions, so they do not receive significant retraining
Use database technology while becoming a similar problem. In the past, hierarchical, network databases are very commonly used in near-term work and relational databases.
Documentation on the functionality of the application, at least not last, is almost always inadequate, and only a few people have
Extinct vendors-
Many are reported, and in this case, our company will lose its proprietary development application. In most cases, the language used to develop the system is already outdated and is no longer supported, so the customer is in a very volatile position Furthermore, the system is usually highly customized and appropriate documentation Is not maintained. This also applies to the full-fledged environmental changes that carry out major bottlenecks.
Therefore, when it comes to taking the necessary system, it is a high learning curve because it requires maintenance. This period varies from two months to six months depending on the complexity of the system. Only after becoming familiar with the system will third parties be able to perform effective maintenance tasks.
Align with business goals-
Some Cio sure do not think that it would be beneficial to be uneasy or to maintain or improve overtime with the legacy system. It actually reduces the mere running costs which should not be considered for healthy investments with any spending.
There are three different types of maintenance costs: preventive (eg Y2K, euro), adaptation and failure. The cost assigned to these is the running cost, as preventive maintenance and repair costs are required to maintain the operation of the system.
Adaptive maintenance generally indicates reinforcement or improvement. While this maintenance is phased, it improves functionality and accessibility and provides business value. Unfortunately, most consolidation requests take the back seat as the allocation of most budgets consumed by the prevention and maintenance of breakdowns.
The improved return on investment is obtained by undertaking a major improvement only when the business needs it most, but it too.
For legacy upgrades, figure out whether increasing returns will bring value or reduced TCO (maintenance, infrastructure, operating costs)
Tsutsutsutsu
Broadly communicate within the organization, and adopt legacy systems from Japan to make it a strategic business need related to financials. With a variety of options and changing CIOs, it is more modern with legacy systems.
