Legacy systems have helped many companies get to where they are today, but those same applications are the ones that, sooner or later, become obsolete over time and slow down business growth.
Upgrading obsolete systems and applications is crucial for a company to continue to ensure success, make better decisions, and create a well-thought-out IT strategic plan. We tell you how to approach it and choose the strategy that best suits you.
Legacy systems refer to any software, technology, or process used by an enterprise that is no longer as effective as it once was or has become obsolete.
As applications and systems enter legacy systems status, they add challenges and risks associated with outdated technologies to the business, such as hacked integrations, lack of support for third-party integrations, security threats, and compliance risks, poor customer experience, etc.
The modernization of legacy applications involves replacing these obsolete systems with new solutions that make use of modern architectures oriented towards obtaining the maximum benefit provided by the cloud services available between the different hyperscalars. This involves analyzing current solutions, migrating them, and incorporating new features that make use of the new technologies available on the market.
It may initially seem daunting and difficult, but working with obsolete IT systems is even more complicated and dangerous. Opting for this modernization will result in more efficient processes, teams, and customers with better experiences, resulting in reduced costs and risks.
Modernization is not necessarily about replacing these applications entirely but rather about upgrading them and refocusing them to meet current needs and standards.
Some of the main benefits are:
In the process of application modernization, several key technologies come into play:
While agility has always been a priority in IT, many legacy systems are critical to some business operations, so it is crucial to examine the ongoing cost of maintaining these legacy systems against the benefits of application modernization.
The process of modernizing legacy systems goes through a process of evaluation to determine the best approach to address it.
There are six main drivers for modernizing legacy applications, which stem from the problems or impediments that the application or system has created as a result of its technology, architecture, or functionality.
The first three drivers come from the business perspective, such as business fit, value, and agility. If applications do not meet new digital requirements or lack the agility to keep pace with demand, they need to be modernized to provide greater business value and not pose a risk.
The remaining three drivers are from the IT perspective and involve cost, complexity, and risk. If the cost is too high, the technology is too complex, or compliance and support may be compromised, it is time to modernize systems.
Once we have the initial assessment, it is time to refine the issues causing friction among users in more detail.
Understanding what works well and what does not in legacy software will be critical in determining the approach to modernization.
Once the possibility of modernizing a legacy application is confirmed and the problem is clearly defined, it is necessary to define how to do it. Seven approaches (“the 7Rs”) can be chosen, ranked from the lowest to the highest level of complexity, as well as the lowest risk or impact:
When choosing between the seven approaches, you should consider options such as workload, architecture, cost, risk, operations, or security.
The weight of each option will depend on the priority you give to each in your business. You will also have to choose between re-architecture, rebuilding, or replacement. The former has medium costs and risks, but the latter two have better results with higher costs and risks. The key, therefore, is to weigh up all the options to help identify to what extent each will have the desired effect with the minimum effort and the greatest positive impact.
Legacy software is often monolithic in design, which can be a major block to upgrading applications. In fact, the average lifespan of an application is 6-8 years, but organizations are subject to constant change from the market, consumers, and the economy.
Choosing flexibility and agility to pivot in today’s changing landscape is crucial to ensuring business success and competitiveness.
Often, internal teams may lack the skills to modernize legacy systems, causing many companies to neglect this task as one of their objectives. It requires constant training, and there are usually insufficient resources to make the right decisions when approaching this process.
Having a technology partner is the best solution to maximize time to market and achieve the best results in the short, medium, and long term.
Transformation is a constantly moving and changing process, so once a project has begun, it is critical to iteratively test and optimize application modifications to ensure no issues with hosting, software licensing, or connectivity to other services or databases during the transition.
Once you have made the decision to modernize your legacy applications, the most appropriate approach will depend on the particular problem you are trying to solve. In fact, this will be key to ensuring the success of the process.
At Plain Concepts, we specialize in application modernization through services that accelerate the move to the cloud, as well as supporting you on your journey to a digital enterprise that a modern and evolving infrastructure foundation underpins.
To this end, we provide you with several services that will help you achieve the business goals you were looking for:
