Legacy Systems Management

Question: Write an Eassay on Legacy Systems? Answer: Introduction The old technologies, method, application system or computer system is known as legacy system in the computing world. The legacy systems that are still in use are in a dire need of replacement. There are many organizations that still use these legacy systems. These legacy systems are still in use because it is been in use since the earliest period of time and the organizations are hesitant to change them completely. The organizations are hesitant because of the fact that if the whole system is changed than how will the organizations keep running till the new systems are installed (Aciworldwide.com, 2015). Many new systems or computer programs are developed these days, they are far more easy and flexible in nature. The computer languages that are in huge demand and are being used in many organizations are: c, c++, java and unix. Still the use of legacy system is present in many organizations. Significance Of Legacy Systems Organizations spend a huge amount of money to install software systems to get the desired results. They spend the money thinking that the software will be in use for many years. Market is changing constantly in a fast pace ad with it the software are being updated as well as many new software are being introduced in the market. Still the companies tend to stick with the software that they have been using for a long time. Organizations still rely on the old systems because these systems play a very vital role in the organizations services or products. Many old systems have become very vital in many businesses because they perform their daily work using these legacy systems. Situation might arise where the organization will not be able to function if these systems collapse (Aciworldwide.com, 2015). A constant change is taking place in each part of the market and these legacy systems have incorporated all these changes over the years. It can be said in a way that these systems have a lo t of information in them and changing it would be a very difficult task. Organizations change or replace their machines and systems frequently to match with the change in market, but changing these legacy systems might be a little risky. Changing the systems to incorporate new and latest systems might produce results that are not correct or may not perform up to the mark as it used to do earlier. Advantages Of Legacy Systems Using legacy systems could cost the organization more than using a new system, but there are many advantages of using these legacy systems (Aciworldwide.com, 2015). Some of the advantages of Legacy systems are as follows: Risks related to installing new systems that have not used before will be reduced. This is so because the organization knows how to work with the present system and know the results that are generated from using the legacy systems. The organization will not have to spend any money, thus cost to install a new system will not come to play. With the changing market the legacy system have also incorporated these changes in them and by doing so they have a lot of vital information present in them. They have information about the company from the earliest of time and thus all these data can be easily accessed. Installing a new software will complicate accessing data and the method of working. Modernizing Legacy Systems The legacy systems can be completely replaced or updated. There may be a lot of challenges in modernizing legacy system that is present in any organization. A legacy system can be modernized to meet the new demands in the market. With passing time new and fresh software are launched that are more flexible, less complicated, structured and less costly. The legacy systems can be replaced with any of the software that is close enough to the requirement of the company, but replacing the whole system may come with many risks (Aciworldwide.com, 2015). The legacy system can be updated, updating the system will be a better option as the whole system will not be changed and the functionality will remain same. Updating legacy system will be helpful for the company. The company then will not have to appoint new employees or expert who knows how to work with the new software. There will be no change in platform and thus the result obtained will be consistent. Conclusion A legacy system has its own set of advantages and disadvantages. Companies or organization have to change their working method with the change in the market. To stay ahead in the competition the systems must be modernized to a length where there are no risks or damage to the organization. Reference com,.
