What Is Legacy Application Modernization? First of all, legacy applications are any software applications that have become obsolete, either on their own merits, because they no longer serve the complete needs of a business, that they no longer properly function in a changing world, or any combination of these. With legacy application modernization, parts of the existing, outdated business applications are taken and modified so as to have the necessary modern capabilities and features. By converting legacy applications into a contemporary interface the following advantages are realized quite quickly: IT costs are reduced The company achieves greater flexibility Increased collaboration Improved consistency A legacy application modernization can be thought of as a system wide software update. Because the old legacy applications are used, many of the original pieces remain the same, lending to a robust platform overall, but one that can fully integrate with a modern interface, and in today's world, that means being able to adapt to an increasingly digital world, including technology such as the cloud. What Problems Does a Legacy System Create? A legacy system by its nature presents the business with several problems. Overall Obsoleteness: By its definition a legacy system is obsolete, and is likely to be creating bugs, errors and critical issues. Outdated technology might have issues interfacing with new hardware or digital systems, such as the cloud. Loss of Documentation: Over time the system's documentation can become outdated or incomplete. Employees Don't Know How to Run Older Systems: Over time new employees will come in, only to find an outdated system. Eventually this will lead to a lack of knowledge to properly run the system. Support Ceases for Old Legacy Systems: Software used for legacy systems will no longer be supported. Decreased Business Continuity: A problem-filled technology system makes consistency impossible. Less Overall Reliability as a Business: It likewise leads to less reliability. Skyrocketing IT Maintenance Costs: The cost and energy to just maintain a legacy system increased exponentially as it becomes more outdated. Perhaps one of a legacy system's greatest dangers is the complacency it breeds. Nearly half of CIOs believe that the complexity of their legacy system makes updating prohibitively out of reach. And remember, this long list of problems doesn't occur in a vacuum. Very often one problem can lead to another or to many. For example, outdated documentation feeds into the loss of employee knowledge in running the system. This is why application modernization is so critical. What Are the Benefits of Modernizing a Legacy System? There are numerous benefits to modernizing legacy applications, with strong numbers to back them up. Here is a quick overview of the primary benefits: Reduced Costs: Modernized legacy software can reduce costs by 13%. Better Productivity: Developer productivity can be increased by 40%. Better Performance: Overall annual revenue can increase by 14%. Greater Agility: Greater efficiency serving existing customers and vendors and greater opportunities for new growth. Better Customer Support: The customer is best-served by a well-functioning system. Increased Compliance: Software non-compliance costs companies time and money. Modernization saves on both. Improved Security: Modernization allows for the latest security innovation, ensuring that a company's is the best and most up to date it can be. Lets take a closer look at the myriad of reasons why legacy application modernization can be so important for a business. Reducing Costs There are numerous ways that modernizing legacy applications will reduce costs but one of the most relevant examples to today is the ability to migrate to the cloud. Transferring to the cloud negates the need for the overhead costs of on-site datacenters. Cloud-based systems are much more scalable, and come in a variety of affordable rate packages. Another huge cost saving area with modernization comes with maintenance. Companies are often spending a staggering 60% of the IT budgets just on maintenance of old systems. And remember, with an older system simply diagnosing can be severely hampered by a lack of documentation and knowledge from the team. Better Productivity With access to the most sophisticated software, developers will get more done and be able to work together more smoothly as teams. One great example of this is in how cloud technology can best meet the needs of individual teams, be that increased data or greater bandwidth, in a way that many legacy systems simply cannot. Better Performance Just like the negatives of a legacy system can feed on each other, so can the benefits. The increased productivity and consistency leads to better performance and higher overall annual profits. Greater Agility Because the system-wide improvement instantly leads to a large company-wide one, overall agility is greatly increased on several levels. Better reliability, consistency, and most importantly efficiency allows for better service to current customers and opens the door to many new customers and opportunities. Additionally, without being hampered by the problems of legacy applications, the launch of new products, from conception, design, planning through implementation is all much simpler. The ability to adapt the company are endless. From being able to truly offer remote work because a web-based system allows for real time work from employees regardless of where in the world they are to offering higher value services to customers because of a greater and more consistent web-based presence. Better Customer Support First off, consider that some legacy applications are paper based. And for many that aren't they are as reminiscent of paperwork that they might as well be. Efficient data entry, better project tracking and records that are kept securely in the cloud and can easily be called up correctly goes a long way in providing high quality customer support. Increased Compliance Non-compliance costs millions, yet managing and updating logs is time consuming and prone to errors in many legacy systems. Modernizing makes this process simple and automatic. Improved Security Although listed list, this is possibly the number one benefit of modernizing legacy applications. As security becomes more and more important for every company and nonetheless harder to maintain, having a legacy system will always leave a company vulnerable to attack or even innocent leaks. In today's world, to depend on security systems based on technology from several years ago is asking for trouble. Application modernization provides a company with access to the most powerful security of today. How Does Modernizing Legacy Applications Work? A large part of integrating the modern system into the legacy one is through open source code. This allows for the modernization process to re-architect the legacy code with open source, so that new developers are able to work on the system without specialized training in the company's specific system. But modernization can come in many forms, from re-platforming and re-coding to re-architecting and re-hosting, the path to legacy modernization can take numerous forms. And yes, it does include the possibility of an entire replacement. But generally the idea is to take the parts of the system that are still of value and keep that while updating the rest of the system so as to provide what is needed and to be able to adapt easily in the future. Today legacy modernizations don't have to provide the same disruptions they once did. In fact, when done right they are designed to disrupt as little as possible while providing as much benefit. In fact companies can choose how intensely they want to take on a modernization at one time. There are three overall ways of approaching this: Complete Transformation: This means getting rid of the entire system and starting new from the ground up in one go. Module Level Replacement: This allows a company to replace a major part of the IT system at a time. Eventually all parts are replaced. Micro-Level Replacement: At this level the core system, technology and architecture remain unchanged while new technology is introduced for dealing with specific issues.
