Business development management tools in the digital economy

The peculiarities of the digital environment, which contribute to the rapid growth of instability in enterprises' activities, are highlighted. The need to refine certain aspects and tools of traditional strategic planning is substantiated. The essence of digital transformation as a strategic process of business change—based on client-centric principles, systemic innovation, business model adaptation, active data usage, and competency development—is defined. The problems facing Ukrainian companies in digital transformation are highlighted, including insufficient strategy development, organizational culture misalignment with necessary changes, a shortage of digital skills, outdated technologies, lack of coordination between old and new technologies, and the high costs of implementing innovations. The approach to the digital transformation strategy is viewed as a tool for setting priorities that provides businesses with competitive advantages in rapidly changing markets through the application of digital technologies to solve new business challenges. Potential directions for ensuring the flexibility of a digital strategy are highlighted, such as developing partnerships and cooperation, utilizing big data analysis and predictive analytics for real-time decision-making, and employing flexible technologies for both implementation and strategy development. A hypothesis about the feasibility of developing a minimally viable strategy is proposed. As an additional method for increasing the flexibility of the digital transformation strategy, a modular structure for its design is proposed, based on the concept of business architecture, establishing a close connection between enterprise strategy, business model, and IT architecture. A brief overview of digital business models is provided, indicating that ecosystem-type business models, including digital platforms, are the most successful in the digital environment. The stages of digital transformation are outlined, and additional tools for their implementation are considered, such as digital maturity assessment models, a system of key indicators, and a digital transformation road map. A generalized structure of the toolkit for strategic management of business development in the digital environment is proposed, particularly aligned with the stages of digital transformation implementation.

The smart village is the digital transformation concepts used to organize the economic sector improvement within the village government's scope in supporting and realizing the SDG's sustainable development goals. The selection of objects in this study was based on the Developed Village Index (IDM) classification in the Advanced Village group. Desa Sembubuk is one of the villages in Jambi Province with the status of IDM Advanced Village. The Sembubuk Village Government can carry out smart village implementation to optimize and increase the effectiveness and efficiency of village economic improvement programs such as community skills training and BUMDes management. In implementing a smart village, there must be alignment between the government's strategic plans and technological needs. For this reason, Enterprise Architecture (EA) design is required. The guidelines for creating EA in this study use the TOGAF 9.2 framework. The result of this research is an IT Roadmap and EA design in Sembubuk Village, which can be used as a guide in implementing a smart village.

Master Data Management Disruptive Modern Architecture

Master Data Management concept came into the mainstream during the mid 2000s, to generate a single Golden profile of the customer. As the Enterprise IT architecture started adopting and integrating various Commercial Products for CRM, ERP, Finance, HR, Supply Change Management etc. along with other homegrown custom apps, the information around the Customer started drifting across the various applications which resulted in various inefficiencies in day-to-day business operation. Master Data Management tools and technologies provide a way to perform identity resolution and survive latest and greatest information. Traditionally, the MDM tools always adopt a lean approach that uses minimal attributions to identify the smallest amount of (master) data with the biggest influence on business outcomes like Name, Phone, SSN, Email and Address. These constitute only less than 1% of the enterprise data, In the age of generative AI, there is a greater need to understand the context and the relationship of ALL data. This paper explores an alternate approach to mitigate the shortcomings of the currently available MDM tools

Enterprise IT Architecture Greenfield Design Combining IEC 62264 and TOGAF by Example of Battery Manufacturing

IT-systems supporting business operations are a cornerstone of industry 4.0 and smart manufacturing. IT-systems must not be considered as an end in itself. The enterprise IT architecture must be aligned with the business goals and strategy. Current approaches for designing enterprise IT architectures provide little guidance for greenfield environments in which there are little given boundaries, such as operation procedures. In smart manufacturing this is challenging due to the complexity of the shop floor involving OT and IT. This paper addresses this gap by combining the TOGAF architecture development method with the manufacturing operations management standard IEC 62264. The paper explores this combination by the example of designing an enterprise IT architecture for the Fraunhofer battery manufacturing research line involving the TOGAF phases architecture vision, business architecture, information systems architecture and technology architecture for manufacturing.

IT-architecture management for small businesses based on total cost of ownership models

The article is dedicated to the tasks of IT architecture management according to the specifics of small and medium-sized businesses. The article comprehensively considers the object model of the IT service as the main component of the IT-architecture management. In the article, the authors propose to present an object model on different layers, which allows to consider the elements of the IT-architecture from different points of view. The service object model has logical and physical layers, where the physical layer consists of the hardware and some software components and the logical ones are the systems and subsystem as software products, and the service itself as a business value. The authors describes the main aspects of using the object model to identify elements of the IT-architecture. This shows that subsystems and the physical layer allows to apply the model of total cost of ownership. The study also identifies key steps in applying the total cost of ownership model to enterprise IT-architecture management; the most difficult stages for the development of small and medium-sized businesses are noted. As a result of the study, the authors developed an approach that allows you to determine the cost of individual IT-systems and their corresponding elements of the sharing infrastructure, taking into account the structuring of costs based on the total cost of ownership model. The authors assume that this approach will be most useful for small and medium-sized businesses. The authors propose to use approaches based on the use of an IT-service object model and a total cost of ownership model for solving IT-architecture management problems. The use of an object model allows to identify business value enterprise IT architecture, its components and their infrastructure elements. Applying the total cost of ownership model enables to use cost management the IT architecture.

Function-oriented approach to mining enterprise automation

Nowadays a production enterprise is inconceivable without the automation of all its processes – technological, production, and managerial. The efficiency of an enterprise largely depends on high-quality data processing within a single information space. The introduction of an integrated automated management system for an industrial enterprise, consistent with the business model, will eliminate many of the problems arising during creation, integration and development of automated systems, will create an effective enterprise management system and will reduce future costs of production modernization. Current trends of digital transformation increase the demand for an integrated business management system model, that would include a model of an integrated information management system as an integral part of it. The study aims to develop a reference functional model of mining enterprises, including a comprehensive vision of business, production and technological processes and their IT support. The model proposed is based on the analysis of existing international industry approaches to automation, as well as the experience and best practices of automation of mining enterprises. The methodological foundations of the research include enterprise architecture approach (including the concept of service-oriented architecture) and authors' function-oriented approach for engineering the IT architecture. The article describes a reference functional model of a mining enterprise, on the basis of which the structure of the mining enterprise IT-architecture functional structure is determined. The function-oriented approach for engineering IT-architecture as a reflection of the business functional structure is a good example of the symmetry phenomena in enterprise management. Further research will be devoted to the issues of designing an information exchange model and a data architecture model for the mining value chain and its individual parts in interconnection, as well as reflecting end-to-end processes of mining enterprises in the IT architecture based on the developed model for determining the boundaries of functional blocks of information systems

A Privacy-Preserving Outsourcing Data Storage Scheme with Oruta Data Auditing

Cloud Computing has been envisioned as the next generation architecture of IT Enterprise. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, Cloud Computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. With cloud computing and storage, users are able to access and to share resources offered by cloud service providers at a lower marginal cost. With cloud computing and storage services, data is not only stored in the cloud, but routinely shared among a large number of users in a group. In this project, we propose Oruta, a privacy-preserving auditing scheme for shared data with large groups in the cloud. We utilize ring signatures to compute verification information on shared data, so that the TPA is able to audit the correctness of shared data, but cannot reveal the identity of the signer on each block. We can implement the batch auditing scheme to perform efficient public auditing to protect both identity and data privacy in cloud environments.

HASG: Security and efficient frame for accessing cloud storage

StaaS (Storage as a Service) has been envisioned as the next generation architecture of IT enterprise. Enterprise, individual end users move more and more important information to outsourced data centers, where the data may be misappropriated in the malicious model. Moreover, users hesitate to store data in the cloud storage because of network fluctuation. Security and availability become the main concern of cloud storage. This paper, to address these issues, presents an architecture of High Available cloud Storage Gateway(HASG). In our design, data file is divided into implicit, redundant blocks by file fragment algorithm. Part of these blocks, which are stored on different designated cloud servers, can be used to reconstruct original file. Additionally, dynamic service provider selection algorithm and redundant block mechanism for file updating is proposed to effectuate cost and bandwidth savings and accelerate data accessing. Experimental results illustrates that our design enhanced security of cloud storage and improved data access efficiency.

Efficient and Reliable Data Storage Securityagainst Malicious Data Modification in CloudComputing

Cloud Computing becomes the next generation architecture of IT Enterprise. In contrast to traditional solutions, Cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique feature, however, raises many new security challenges which have not been well understood. In cloud computing, both data and software are fully not contained on the user's computer; Data Security concerns arising because both user data and program are residing in Provider Premises. Clouds typically have single security architecture but have many customers with different demands. Every cloud provider solves this problem by encrypting the data by using encryption algorithms. This paper investigates the basic problem of cloud computing data security. We present the data security model of cloud computing based on the study of the cloud architecture. We improve data security model for cloud computing. In proposed system, we are going to make robust data storage security model in which group member’s data accessing scheme is used, for dynamic groups in the cloud. We analyze the security of our scheme with data confidentiality and demonstrate the efficiency of our scheme in experiments against malicious data modification.

Survey on Secured Data Transferring in CloudComputing

Cloud computing has gained a lot of hype in the current era and it is said to be the next big thing in the computer world after the internet. Cloud computing is using Internet for the tasks performed on the computer and it is visualized as the next- generation architecture of IT Enterprise. Cloud computing is attached to several technologies and the union of various technologies has emerged to be called cloud computing. Cloud Computing transfers the application software and databases to the enormous data centers, where the administration of the data and services may not be fully honest. This irreplaceable attribute poses many new security challenges which have not been well understood. In this paper, we discuss the mechanism that not only protect sensitive data by enabling computations with encrypted data, but also protect customers from malicious behaviors by enabling the validation of the computation result.

A Survey on Data Integrity Techniques in Cloud Computing

Cloud computing which is envisioned as the next generation architecture of IT Enterprise comes into focus when someone thinks about what IT always needs. It is way to increase capacity or add capabilities without investing in infrastructure as well as licensing cost on new software. Besides of this advantage there is one major problem that needs to face while keeping sensitive data in cloud, Assurance of data integrity that is data remain as it is on server for long time. Client cannot physically access the data from the cloud server directly, without client’s knowledge, Cloud Service Provider (CSP) can alter or delete data which are either unused by client from a long a time or takes large memory space. Hence, there is need of checking the data periodically for its integrity, checking data for correction is called data integrity. To overcome data integrity problem, many techniques are proposed under different systems and security models. This paper will focus on some of the integrity proving techniques in detail along with their limitations.

architecture of IT enterprise. The cloud paradigm advantages and its potential for decreasing costs and reducing the time for a service that favours towards security issues. Cloud Computing is an aggregation of IT services that offered to the customer based on leasing. Though a large number of security issues are addressed, still some are not addressed and several algorithms are proposed for security issues. This paper presents a perspective of cloud computing technologies, essential characteristics, classifications, delivery models and various encryption mechanisms. A comparative study made on several encryption techniques are used for maintaining the confidentiality in the cloud. Finally, the major data security issues present in cloud computing are discussed.

Adoptive Cloud Application in Semantic Web

Cloud computing has been envisioned as the next-generation architecture of IT enterprise. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique attribute, however, poses many new security challenges which have not been well understood. In this article, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose an effective and flexible distributed scheme with two salient features, opposing to its predecessors. By utilizing the homomorphic token with distributed verification of erasure-coded data, our scheme achieves the integration of storage correctness insurance and data error localization, i.e., the identification of misbehaving server (s). Unlike most prior works, the new scheme further supports secure and efficient dynamic operations on data blocks, including: data update, delete and append. Extensive security and performance analysis shows that the proposed scheme is highly efficient and resilient against Byzantine failure, malicious data modification attack, and even server colluding attacks.

Enabling public verifiability and availability for secure data storage in cloud computing

The use of cloud computing has increased rapidly in many organizations. Cloud computing provides many benefits in terms of low cost and accessibility of data. Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. It moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. The major advantage with this technology is it is cost efficient. But there follows a key disadvantage associated with it, the disadvantage with it is the security issues related to the data stored on clouds. We have first identified the potential security problems and the difficulties with fully extension of data dynamics in the cloud and service availability. While prior works ensure remote data integrity, they lack public verifiability and data availability. Hence the aim here is to ensure data integrity with public verifiability and availability. We have constructed an elegant verification with access rights scheme for seamless integration of these two salient features in our protocol design. This paper in particular tries to achieve public verifiability by manipulating the classic Merkle Hash Tree and moving towards multi clouds or in other words inter-clouds which has emerged recently. We have tried to assure data availability by adopting DepSky System model for multi-clouds.

A SECURE DATA FORWARDING SCHEMA FOR CLOUD STORAGE SYSTEMS

Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. It moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. This unique paradigm brings about many new security challenges, which have not been well understood. This work studies the problem of ensuring the integrity of data storage in Cloud Computing. In particular, we consider the task of allowing a threshold proxy re-encryption, on behalf of the cloud client, to verify the integrity of the dynamic data stored in the cloud. The introduction of TPA eliminates the involvement of the client through the auditing of whether his data stored in the cloud are indeed intact, which can be important in achieving economies of scale for Cloud Computing. The distributed storage system not only supports secure and robust data storage and retrieval, but also lets a user forward his data in the storage servers to another user without retrieving the data back, since services in Cloud Computing are not limited to archive or backup data only. While prior works on ensuring remote data integrity often lacks the support of either public Audit ability or dynamic data operations, this paper achieves both. We first identify the difficulties and potential security problems of direct extensions with fully dynamic data updates from prior works and then show how to construct an elegant verification scheme for the seamless integration of these two salient features in our protocol design A decentralized erasure code is an erasure code that independently computes each code word symbol for a message, where TPA can perform multiple auditing tasks simultaneously. Extensive security and performance analysis show that the proposed schemes are highly efficient and provably secure.

Enabling Integrity for the Compressed Files in Cloud Server

Cloud computing has been envisioned as next-generation architecture of IT enterprise. Cloud computing is the internet based model which delivers computing services on demand. Cloud storage moves the users data to large data centers, which are remotely located and on which user does not have any control. Apart having more benefits, this unique feature of the cloud also poses many new security challenges which need to be clearly understood and resolved. The important concerns that need to be addressed in cloud computing is to assure the integrity of data i.e. correctness of his data in the cloud. In this paper we provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be done by both the cloud and the customer and can be incorporated in the Service level agreement (SLA). Here we are encrypting the hash values and providing the more security. This scheme ensures that the storage at the client side is minimal which will be beneficial for thin clients. Here the computational time is minimized by using integrity and encryption methodology on the data in cloud . It should be noted that this scheme applies only to archive storage data.
