Introduction

In the context of contemporary digital transformation, the economy imposes strict demands on the adaptability, scalability, and fault tolerance of information infrastructures. This has led to a shift in architectural paradigms toward distributed systems, which provide horizontal scalability through load balancing across nodes, data replication, and decentralized control mechanisms that ensure data integrity—often implemented using Paxos and Raft algorithms. Microservices architecture further accelerates CI/CD cycles and facilitates the integration of heterogeneous sources (CRM, ERP, IoT, external APIs) into a unified ecosystem.

Real-time data streaming and predictive big data analytics challenge centralized architectures by creating bottlenecks in throughput and system resilience. In contrast, hybrid clouds and edge computing bring computation closer to the data source, reducing latency and increasing fault tolerance [1].

The relevance of this topic is reinforced by the dynamics of the global IT services market: the sector reached USD 1.40 trillion in 2023, is projected to hit USD 1.50 trillion in 2024, and is expected to surpass USD 2.98 trillion by 2034. This growth highlights the rising demand for flexible and reliable distributed solutions capable of dynamically adapting to technological disruptions and evolving market conditions [10].

The aim of this article is to analyze the theoretical and methodological foundations for the development of distributed systems in the context of digital transformation.

To achieve the stated objective, the tasks are:

1. To conduct an analysis of the evolution of approaches to designing distributed systems;

2. To examine the specific features of implementing distributed systems within an organization.

The novelty of this study lies in offering an alternative perspective on the development of distributed systems that transcends traditional methodological paradigms. Unlike conventional consolidated approaches, the emphasis here is placed on integrating distributed systems with digital trends, enabling not only technical efficiency but also laying the groundwork for adaptive, self-learning architectures.

The working hypothesis posits that the implementation of distributed systems based on modern digital technologies contributes to the improvement of business process efficiency and enhances enterprise resilience amid digital transformation. It is assumed that integrating distributed architectures with innovative management methods can significantly enhance the adaptability and security of information systems.

The research methodology is based on comparative analysis of existing theoretical models.

Materials and methods

The literature on the theoretical and methodological foundations of distributed system development under digital transformation reflects a broad spectrum of approaches, which can be attributed to the interdisciplinary nature of the subject. Research focusing on digital transformation in the context of security and enterprise performance improvement reveals a systemic approach to analyzing transformational processes. For instance, Cherep A., Dashko I., and Ohrenych Y. [1] justify the need to formulate a concept for ensuring socio-economic security in the context of business process digitalization, highlighting the structural shifts that accompany such transformations. Concurrently, Jabborova D. et al. [2] explore the potential of advanced technologies for sustainable development, reflecting a practical orientation toward enhancing organizational competitiveness. Additional empirical validation is provided in the work of Weritz P. et al. [3], which examines the role of strategic capabilities in the success of digital transformation and firm performance through the integration of theoretical models and practical case studies.

A second cluster of research emphasizes human capital management and public support mechanisms, which are particularly relevant in today’s dynamic economic landscape. Gudz P. V. et al. [4] analyze the role of government support tools for small and medium-sized enterprises, demonstrating that state policies and support measures are critical to enterprise adaptability in volatile environments.

A third thematic focus is the application of innovative methods and technologies to address environmental sustainability and improve natural resource quality. In this domain, Abdullah D. et al. [5] employ artificial neural networks and hybrid wavelet-based methods to assess water quality, underscoring the potential of computational tools in environmental monitoring. The study by Narinbaeva G., Menglikulov B., Siddikov Z., Bustonov K., and Davlatov S. [6] highlights the use of innovative technologies in agriculture, stressing the importance of digitalizing the sector to increase its efficiency. Similarly, Uralovich K. S. et al. [7] draw attention to the significance of environmental education as a primary driver of sustainable development, emphasizing the need to integrate educational initiatives into broader environmental safety strategies.

The fourth group of works is represented by sources [8, 9], with data published on the websites reqtest and geeksforgeeks, which were used to schematically illustrate architectural solutions in the field of distributed systems.

It is also worth mentioning source [10], with information available on precedenceresearch. Its inclusion was essential to demonstrate the relevance of the topic.

This literature review reveals both commonalities and divergences in the study of digital transformation across various economic sectors. Notable discrepancies exist in the interpretation of core concepts such as security, sustainability, and efficiency, reflecting the diversity of theoretical frameworks and methodological approaches. Furthermore, the issue of interdisciplinary integration between theoretical foundations and practical implementation of digitalization remains underexplored, as does the detailed analysis of how digital technologies affect socio-economic and environmental processes. These gaps call for further research aimed at establishing a unified methodological basis for assessing the impact of digital transformation across different domains.

Results and discussion

Distributed systems represent an architectural solution in which computational resources and data are distributed across multiple independent nodes interconnected through a common network. This design enables high scalability, fault tolerance, and flexibility in supporting business processes within the context of the digital transformation of the economy. At the core of the distributed systems concept lies the principle of decentralization, which minimizes dependence on a single control center and allows for rapid adaptation to changes in the external environment [1].

From a theoretical perspective, distributed systems are understood as a collection of interconnected computing components located in different geographical locations, operating synchronously to achieve a shared objective. Such distribution reduces the risk of failure in individual elements, enhances performance through parallel data processing, and increases resilience under sudden workload fluctuations [6].

The main architectural models of distributed systems include:

• Client-server model: A traditional model where servers provide resources and clients request access to them (fig.1.).

Figure 1. The client-server model [9].

• Microservices architecture: A modular approach in which a system is divided into small, autonomous services that interact via standard protocols (fig.2.).

Figure 2. Architecture of microservices [9].

• Peer-to-peer (P2P) architecture: A design that distributes roles equally among nodes, improving both fault tolerance and scalability (fig.3.).

Figure 3. Peer-to-peer (P2P) architecture [9].

Each of these models has its own particularities regarding data processing organization, security assurance, and integration with digital technologies. The use of a microservices architecture, for example, enables rapid implementation of new features and fast adaptation to the evolving demands of the digital economy [1, 3].

The digital transformation of business necessitates the implementation of flexible and scalable IT systems capable of processing large volumes of data and supporting real-time decision-making. Distributed systems, due to their architectural versatility, have become fundamental components of enterprises' digital infrastructures. They contribute to:

• Business process optimization: Decentralized computing power significantly reduces data processing time.
• Enhanced security and fault tolerance: Load distribution across multiple nodes lowers the risk of total system failure.
• Integration of new digital services: Distributed architectures simplify the implementation of innovative technologies such as artificial intelligence, Big Data, and IoT, directly influencing enterprise competitiveness [3].

To better understand the features of distributed systems, Table 1 provides a comparative overview.

Table 1.

General characteristics of distributed systems [1, 3, 6].

As demonstrated by these characteristics, distributed systems play a central role in shaping the digital economy, offering the flexibility, scalability, and fault tolerance required for effective digital transformation. These attributes are essential for adapting business processes to rapidly shifting market conditions and increasing data processing demands.

The development of distributed systems requires the integrated application of modern methodological approaches that ensure flexibility, scalability, and high fault tolerance of information systems. The methodology for building such systems is based on a synthesis of traditional engineering methods and innovative digital technologies, allowing for both technical and managerial aspects of their operation to be taken into account.

One of the key methods in developing distributed systems is the use of Agile approaches and DevOps practices (fig.4.), which facilitate rapid response to changing requirements and enable continuous integration and delivery of new services. Agile methodologies support development through flexible iterations, providing adaptive planning, efficient change management, and accelerated development cycles. DevOps tools, in turn, integrate development and operations processes, creating a unified infrastructure for testing, deployment, and monitoring of distributed system components.

Figure 4. Description of DevOps and Agile software development methods [8]

To enhance the reliability and security of distributed systems, formal methods of verification and modeling are widely applied. The use of mathematical models and formal specifications allows developers to identify potential vulnerabilities and architectural flaws at the early stages of system design. International standards such as ISO/IEC 27001, which outlines information security management requirements, as well as standards for integrating distributed computing systems, play a significant role [1]. These methods contribute to building a transparent and reproducible methodology, which is crucial for systems with a high degree of distribution.

Modern distributed systems also actively incorporate innovative digital technologies, including Big Data, artificial intelligence (AI), and the Internet of Things (IoT). Big Data enables the processing and analysis of massive volumes of information, while AI technologies optimize decision-making processes through automated data analysis. IoT extends system capabilities by connecting numerous devices and sensors, allowing for real-time data collection from various sources. The integration of these technologies enables the creation of “smart” distributed systems capable of self-learning and adaptation [3, 5].

A comparative analysis of these methodological approaches is presented in Table 2.

Table 2.

Comparative analysis of methodological approaches to the development of distributed systems [1, 3, 5].

As shown in Table 2, the combined application of these approaches provides a comprehensive methodological foundation for developing distributed systems. The use of Agile and DevOps allows for prompt adaptation to evolving requirements, while formal methods and standards ensure high levels of reliability and security. At the same time, the integration of innovative technologies unlocks new opportunities for automating and optimizing business processes, which is especially relevant in the context of rapid digital transformation. The introduction of distributed systems enables enterprises to optimize business processes and ensure high fault tolerance and flexibility of their information infrastructure [1, 2].

Distributed systems are being deployed through the integration of microservice architectures in finance, manufacturing, healthcare, and e-commerce. For example, in the banking sector, the implementation of distributed platforms not only enhances transaction security but also significantly reduces system response time during peak loads. In the manufacturing industry, distributed systems are integrated with IoT devices to monitor and optimize production processes, resulting in cost reduction and improved product quality [4, 5]. In the realm of e-commerce, distributed solutions support the scalability of platforms for order processing, logistics management, and customer data analytics, which is critical for maintaining competitive advantages in the era of global digitalization [3, 7].

Despite their clear advantages, the practical implementation of distributed systems faces several challenges. The main issues include:

• Ensuring security: Distributed architectures require more sophisticated data protection mechanisms, as information is stored and processed across multiple nodes, increasing the potential attack surface.
• Integration of heterogeneous components: The implementation of distributed systems often necessitates the unification of various technologies and standards, which may complicate compatibility.
• Complexity management: As the number of nodes and services increases, effective monitoring and management systems become essential, which can be particularly difficult during the scaling phase.
• High initial investment: Developing and implementing distributed systems often involves significant financial and resource costs, especially during the initial integration of new technologies.

The future development of distributed systems is closely linked to the continued digital transformation of business and the growing role of innovative technologies. Key areas of advancement include:

• Expansion of artificial intelligence and machine learning applications: Integrating AI into distributed systems will allow for automated management, failure prediction, data processing route optimization, and improved analytics.
• Growth of IoT and Big Data technologies: The connection of large numbers of devices and sensors demands efficient distributed platforms for data collection and analysis, encouraging new business models and faster decision-making.
• Standardization and protocol unification: The development of international standards and protocols will reduce integration costs for heterogeneous systems, ensure compatibility, and accelerate the adoption of innovative solutions.
• Shift to cloud and hybrid architectures: Combining cloud technologies with distributed solutions will enable enterprises to scale their IT resources flexibly and adapt quickly to changing market conditions.

Table 3 presents examples of distributed system implementations across various sectors.

Table 3.

Examples of the implementation of distributed systems in various industries [1, 2, 3, 5].

As the table illustrates, the implementation of distributed systems has already demonstrated its effectiveness across multiple industries. However, several challenges remain that require ongoing research and technological refinement. The prospects for development in this field are driven by the need to enhance business process efficiency and adapt to emerging digital trends—together providing significant opportunities for growth and innovation.

Thus, the integration of distributed systems with modern digital technologies is a critical direction of advancement. It not only enables the optimization of existing business processes but also contributes to the development of new strategic advantages, allowing enterprises to successfully adapt to changes in the digital economy.

Conclusion

The conducted analysis has demonstrated that the application of flexible development methodologies, formal verification methods, and the integration of innovative digital technologies significantly enhances the efficiency and resilience of information systems. The identified research gap—namely, the absence of a comprehensive conceptual model that unites distributed systems with emerging digital trends—has served as the foundation for developing a new model capable of ensuring the adaptability and security of business processes. The obtained results can serve as a basis for further research and the implementation of innovative solutions aimed at optimizing management processes and strengthening the competitiveness of enterprises in an evolving digital environment.
