The pressure on enterprises from new technologies has been accelerating exponentially in recent times. We observe a significant increase in business demands on companies, compelling them to keep pace with rapid technological changes in order not to lose customers and profits. No matter how much a company may prefer to steadfastly use a custom solution created long ago, the world does not stand still. It becomes necessary to step out of your comfort zone and adapt to the evolving landscape by changing existing software. The adoption of technologies such as artificial intelligence, blockchain, cloud solutions, and others compels us to reconsider the concept of ‘stability.’ In this context, stability is synonymous with constant renewal and modernization.
Updating software to ensure competitiveness and meet the requirements of modern business has economic rationale. After all, those who work faster, adapt to existing business requirements, have no security problems, and seamlessly integrate with the latest technologies tend to generate more profits and achieve success faster. The state of a modern company is characterized by a continuous process of renewal. Therefore, it is vital to apply Agile and DevOps methodologies right from the implementation stage, emphasizing rapid implementation of changes and maintaining agility.
And what if the system is outdated? What if it resembles a clumsy mechanism that works stably but does not take into account modern requirements? This is where the reengineering service comes to the rescue, enabling the rapid adaptation of software to changes. Software reengineering is the re-implementation of a legacy system to improve its usability, expand functionality, or introduce updated technologies while simultaneously minimizing the risks and costs associated with redesigning the system from scratch. Reengineering is the key to the success of your business.
Let’s say the key programming language of your company’s system is Cobol, Pascal, Ada, or Fortran. Or if it utilizes obsolete frameworks like JQuery or Silverlight. In such cases, the absence of support for new releases, lack of updates, slow system development, sluggish performance, and insufficient integration with modern technologies can result in data security vulnerabilities, decreased productivity, inefficient workflows, or complete system failure. Moreover, finding specialists familiar with your outdated software may be challenging and expensive.
The application’s outdated and disorganized architecture hinders its development in line with new requirements and scalability needs. Despite the necessity for changes, deciphering the confusing system appears daunting, resulting in numerous errors. Resolving issues stemming from the poor architecture requires substantial financial investment, yet unraveling the complexity of the system seems highly challenging.
Suppose your system features an outdated design that falls short of modern UI/UX standards. If a customer explores your website or a potential partner examines your app for potential collaboration, an uncomfortable user experience could deter them from finalizing any deals.
The need for reengineering arises when there is a shift in business requirements that the existing system cannot support. This entails the implementation of new applications and system components. For instance, changes such as adopting a different order placement process, incorporating user cards, or entirely revamping workflow due to the elimination of a division may be necessary, among other possibilities.
How to switch from all this to normal operation mode? Let’s analyze the approaches to modernization of the company’s software.
Imagine being the owner of a sizable hotel in a tourist hotspot – complete with a restaurant, swimming pool, and park. Once upon a time, this establishment lured in tourists and raked in substantial profits. However, as the years passed, the influx of visitors dwindled. Old, faded carpets, rusty plumbing, a neglected park, and an empty pool no longer captivate them. Modern hotels with sleek designs, conveniences, and updated infrastructure now capture tourists’ preferences.
Now, you face a crucial decision: should you sell the hotel for a minimal sum or invest in its revitalization? Bear in mind that the hotel is situated in an appealing tourist destination. However, significant investment is needed, while financial resources are somewhat limited. After weighing the advantages and disadvantages, you opt to breathe new life into the hotel. Someone else might step in if not you, as the refurbished hotel is bound to yield substantial profits.
Likewise, your company’s software is akin to this aging hotel – it has become rigid and unprofitable, requiring a rejuvenating transformation.
The most straightforward and cost-effective approach involves systematically updating your system by replacing complex code with simpler, more readable alternatives and incrementally introducing small code segments to enhance system functionality. This process is akin to the step-by-step refurbishment of a hotel: starting with a redesign of the facade and lobby, followed by room renovations on each floor. Over time, you progress to repairs of the pool and restaurant.
Implementing these adjustments in the system has a relatively minor impact on your budget, while progressively enhancing the productivity and speed of your application.
System migration to the Cloud involves relocating data, applications, and various business elements from the organization’s local infrastructure to cloud-based services. This transition offers numerous benefits, including cost-effectiveness, scalability, convenient access to applications, and improved collaboration. With this move, your applications gain protection against potential attackers, ensuring that your employees and customers enjoy seamless and prompt access to the system.
In our analogy, outsourcing the hotel’s tasks to specialized services relieves you from concerns about security or maintaining the pool. You no longer need to retain a plumber, gardener, or security guard on staff; instead, you engage services with expertise in these areas, guaranteeing high-level service provision.
It’s important to grasp that complete reengineering involves crafting a new design and architecture for the application. In our context, this entails transitioning from a monolithic system to microservices. Essentially, your revamped system will comprise small, independent components that can change without impacting other parts of the system. This flexibility allows for code rewriting and modifications without compromising the integrity of the entire system.
Developing a system based on microservices can be likened to establishing distinct businesses within the premises of your hypothetical hotel, each operating independently: a restaurant, a bar, a souvenir shop, a yoga club, and a spa salon. A microservices-based system is resilient in crises, adaptable, and more scalable. As a result, your hotel flourishes and generates profits!
Organizations that regularly update and enhance their software through reengineering gain a competitive edge. They can respond more effectively to market changes, customer demands, and emerging technologies, positioning themselves as industry leaders.
