Interrogating the preparedness of Uganda’s Higher Education and the Role of Information and Communication Technology in the era of COVID-19 Pandemic and its Aftermath
This article is based on a qualitative study conducted to establish the preparedness of Uganda’s Higher Education and the role of Information and Communication Technology (ICT) during COVID-19 pandemic and its aftermath. Coincidentally, the dynamics of COVID-19 pandemic predicated the need for urgent adoption and scale up of ICT in education. However, universities in Uganda were strategically ill-prepared to adopt and sustain to digital and online methods of engagement, sighting problems ranging from policy and curriculum deficit, to lack of staff and student preparedness. Ideally, the inability for universities to adopt and sustain to digital and virtual mode of operations demonstrated a strategic irregularity between ICT and higher education systems. In response, this study was intended to address the salient gap by identifying the key pedagogical challenges encountered and recommend appropriate strategic options based on the global best practice in ICT and higher education. Procedurally, the study adopted qualitative study approach, using scoping literature review techniques and content analysis methods of extracting evidence. By way of reflective analysis and scrutiny, the study sought to establish how various universities coped with COVID-19 lockdown, while identifying the relevant information in the domain of ICT and higher education systems. Hence, data analysis followed a descriptive approach, linking the identified gaps with the global best practices. Subsequently, the general implication of the study finding is that there was a strategic mismatch between ICT and higher education systems. Thus, the key challenges identified include lack of pedagogical flexibility and inefficient social interaction among learners and instructors, lack of self-directed and independent learning, restricted mode of assessment, and lack of staff competence in ICT and pedagogical approaches. Hence, this study provides a strategic guidelines to higher education planners to formally integrate ICT functions and education systems.

Machine learning applications for event routing in streaming systems
The paper provides a broad overview and classification of machine learning methods used to optimize routing in distributed streaming architectures. The aim of the study is to provide a detailed analysis of existing approaches: from classical reinforcement learning algorithms to modern deep neural networks, with an assessment of their potential in various operational scenarios and identification of key limitations. The methodological basis was a systematic review of publications dealing with intelligent routing, real-time data processing, and integration of ML solutions into system pipelines. Three main classes of algorithms were identified and considered: reinforcement learning methods (including DQN and actor-critic), deep networks (CNN, RNN and their hybrids), as well as ensemble and evolutionary techniques. The advantages and disadvantages of each class are analyzed in terms of key criteria — response time to flow changes, scalability in the number of nodes, and the ability to dynamically adapt. Special attention was paid to hybrid strategies that combine several models to increase the reliability and accuracy of recommendations on event transmission routes. In conclusion, the main conclusions about the current state of research are formulated and promising areas are outlined: the development of more robust architectures with explicable decision-making logic, as well as the integration of graph neural networks for modeling complex topologies of distributed systems. The presented results will be useful for engineers developing streaming platforms, big data analysis specialists, and research groups working on information channel optimization tasks.

Polycrystalline Organic Semiconductors for Low-Power AI-Integrated Devices: Fabrication and Characterization
Polycrystalline organic semiconductors constitute a promising class of functional materials, combining architectural flexibility, compatibility with low-temperature processing, and tunable electronic properties. Owing to their ability to form ordered morphologies with defined crystallinity, these materials can be seamlessly integrated into energy-efficient intelligent systems—such as neuromorphic components, sensing nodes, and photo-analytical elements. In the context of rapidly growing interest in edge computing and Internet-of-Things infrastructures, they offer advantages over silicon counterparts, including mechanical robustness, spectral sensitivity, and the capacity for on-site primary signal processing. This study reviews methods for producing polycrystalline films, examines how fabrication parameters influence morphological and electrical structure, and surveys quality-control techniques at both micro- and structural levels. Organic semiconductors thus fulfil a strategic role in the design of adaptive, miniaturized, and self-learning devices operating under unstable conditions, forming the basis for subsequent advances in intelligent organic electronics.

Lean MVP Development Via SQL Prototypes: Fast ETL Pipelines, Temporary DWHs, and Accelerated Validation of Product Hypotheses
This paper discusses the use of lightweight SQL prototyping for rapid ETL pipeline construction and MVPs in terms of enabling temporary data warehouses and accelerating product hypothesis validation. It lays out, formalizes, and tests aspects of a Lean Analytical Circuit Building approach based on declarative SQL language such that verifiable metrics may be available to a team without waiting for long procurement and infrastructure approval cycles. Relevance comes with high uncertainty at the beginning of both a startup and product-project development, when classic corporate data warehousing takes from six months up to two years to deploy, thus injecting great schedule and budget risk on top of this, reducing the speed of validated learning through loss of the value of data due to lack of operational feedback. It is new in the mixture of three-tier architecture (Staging, Transform, Data Mart), usage of any current DBMS or cloud engines (in temporary cluster mode, DuckDB, ClickHouse, BigQuery Sandbox), content analysis regarding availability of SQL skills and economic risk assessment together with a systematic comparative and instrumental analysis of performances of prototypes. The main finding is that the cycle from event arrival to target table update can fit within fifteen minutes which means fulfillment of a requirement that needs fast reaction for changes in user behavior and marketing campaigns while keeping the flexibility on the structure level among SQL prototypes preserving transparency and reproducibility plus automatic policies deleting obsolete data and serverless sandbox mode controlling costs. A smooth transition from the temporary solution to stable platforms, according to the Infrastructure as Code principle, minimizes operational risks and ensures continuity of metrics. The article will be helpful to startups and product teams, data engineers, and business analysts seeking to combine the speed of Lean methodology with data reliability.

Leveraging Big Data Analytics for Combating Fake News: A Supervised Learning Approach to Identifying Misinformation on Social Media
The rapid rise of social media has transformed how people consume and share information but has also accelerated the spread of misinformation that undermines public trust, public health, and democratic stability. Manual fact-checking and platform moderation often lag behind the speed of misinformation, highlighting the need for scalable, automated solutions. This study develops a supervised machine learning framework supported by Big Data analytics for fake news detection. Using the ISOT Fake News Dataset of 44,898 labeled articles, we implemented a structured pipeline that included text normalization, tokenization, stopword removal, stemming, and TF-IDF vectorization, followed by training four classifiers: Logistic Regression (LR), Support Vector Machine (SVM), Random Forest (RF), and eXtreme Gradient Boosting (XGBoost). Evaluation was conducted using a stratified 80/20 train-test split with 10-fold cross-validation, applying Accuracy, Precision, Recall, and F1-score as performance metrics. Results show that ensemble models, particularly XGBoost and Random Forest, consistently outperformed LR and SVM, achieving accuracies near 99% with strong precision and recall across both classes. These findings demonstrate the strength of optimized ensemble methods in detecting misinformation and their scalability for real-world application. Beyond model performance, this work proposes a distributed architecture leveraging Apache Spark for real-time deployment, providing a foundation for practical and scalable misinformation detection systems.

Infrastructure Deployment Patterns for AI Services on the Claude Platform
This article questions how to select and use infrastructure patterns in the deployment of industrial AI services on Claude due to the increased enterprise demand and broadened capabilities. This study proves relevant since, within a very short span, generative AI work has transformed from novelty experiments to mission-critical business workloads where effectiveness directly depends on architectural decisions ensuring not only low latency but also cost predictability together with the compliance of corporate security requirements. Therefore, the purpose of this paper is to identify recurring architectural patterns and their operational mechanisms that may be used in balancing response time, context size, cost, and reliability when integrating Claude into enterprise IT systems. The scientific novelty of the research is a detailed taxonomy of infrastructural solutions (serverless gateways, containers in isolated VPCs, batch queues) and how their combination begins to meet the very special challenges of Claude—challenges such as context windows up to one million tokens and loads that seem to increase sharply above 25 billion requests per month. The main findings show that the best setup comes from using small APIs with autoscaling and local cache for interactive work; containers with private links and Batch interfaces when dealing with deep analytics and big processing. The quota system and context thinning, breaking up queues by priority and budget, as well as token control and telemetry, are pieces to help give teams a p95 latency promise while staying inside financial and regulatory fences. The article will be helpful to researchers in cloud architectures, enterprise IT system architects, and practitioners deploying AI services based on Claude models.

PostgreSQL JSONB-based vs. Typed-column Indexing: A Benchmark for Read Queries
A document storage pattern is used in a wide range of business applications, particularly in systems with strong requirements for immutability and auditability. Using the JSONB data type is a common approach to achieving document storage in PostgreSQL, which supports indexing for JSONB. However, building an efficient system for such structures remains a challenge in terms of read latency, mainly due to payload size, recheck cost and value extraction. In this paper, the comparative performance of regular typed-column indexes and JSONB-based indexes is evaluated across ten queries typical of a production application. Generated metrics are used to visualize latency of indexes on JSONB expressions and typed-column indexes and for a one-sided statistical test. The findings show that JSONB-based indexes are not an optimal solution in terms of read performance, and overall typed-column indexes are expected to be at least 20% faster for tables with 1 million records or more. This benchmark is important to consider when designing an efficient data storage for documents.

Cloud Security Architecture for the Automotive Industry: A Framework for Secure Multi-Cloud Deployment
This paper examines the automotive industry since it fundamentally transforms toward Software-Defined Vehicles (SDV) and exponentially increases the reliance on cloud and multi-cloud infrastructures. The attack surface expands in a dramatic way because of a shift to this model. Today cyber risks target centralized cloud backends managing entire fleets not individual vehicles. A comprehensive security architecture should be developed proactively and without delay, as potential threats may escalate, and stringent regulatory frameworks such as UNECE R155 and ISO/SAE 21434 are anticipated to come into effect. In this paper, the Automotive Multi-Cloud Security Framework (AMCSF), which is a conceptual cloud security architecture model for the automotive industry, is proposed based on a systematic literature review as well as comparative analysis of industry practices. ISO/SAE 21434 describes vehicle cybersecurity lifecycle processes the five-layer model would integrate. It works also with modern cloud-oriented technologies like Cloud Security Posture Management (CSPM) and Cloud Workload Protection Platforms (CWPP). The study primarily concludes that risk can be effectively managed in modern automotive ecosystems only if protections are applied synergistically and include both the vehicle itself and its cloud infrastructure. This paper will be helpful to cybersecurity and cloud solution engineers and architects in automotive (OEM, Tier-1/Tier-2), vSOC/DevSecOps teams, cybersecurity and compliance management specialists (CSMS/UNECE R155, ISO/SAE 21434), as well as consultants and executives responsible for designing and operating secure multi-cloud backends.

Federated Learning Approaches for Privacy-Preserving Conversational AI in Dental Informatics
This study investigates how federated learning can enable privacy-preserving conversational AI for dental clinics while complying with GDPR and HIPAA. The main objective is to determine whether clinics can automate patient communications, call handling, reminders, and triage, without transferring raw patient data beyond local systems. The methodology combines a narrative review and comparative analysis of recent healthcare federated-learning studies with a practical deployment blueprint tailored to dental workflows. Three training paradigms are contrasted, local, centralized, and federated, to summarize evidence on model accuracy and computational cost. A layered privacy stack is presented, including differential privacy, secure aggregation, and homomorphic encryption, with guidance on when each technique is most appropriate. An end-to-end workflow is described in which clinics train lightweight local adapters on anonymized speech and text, share only encrypted model updates, and receive an aggregated global model that improves across participating sites. Findings indicate that federated models achieve accuracy comparable to centralized baselines in representative tasks (e.g., segmentation and risk prediction) while keeping patient data local. Cryptographic protections introduce overhead but remain practical when applied selectively. This study demonstrates that federated learning enables privacy-preserving conversational AI in dental informatics without compromising model performance. In practical terms, such systems can reduce missed appointments through targeted reminders, accelerate routing of urgent complaints, and support intern training with simulated dialogues, delivering the benefits of shared learning while maintaining strong confidentiality and regulatory compliance.

Paradigms of ELT Data Pipeline Architectures for LLM Training
This article presents a systematic analysis of ELT pipeline architectures used in the training of large language models. The study is based on an interdisciplinary approach that integrates engineering principles of data infrastructure design, theoretical foundations of transformer architectures, and data flow automation practices under conditions of high source variability. Particular attention is given to the content analysis of scientific and applied publications addressing the role of LLMs in transformation loops, the implementation of agent-oriented solutions, and the support of multimodal adaptive pipelines. Key ELT architecture types are identified, including prompt-driven, agent-based, high-throughput, and cognitively enhanced solutions, reflecting varying levels of model involvement in data processing. The analysis shows that architectural shifts toward feedback integration and dynamic routing enable the creation of robust and adaptive solutions suited to contemporary training scenarios. Special emphasis is placed on issues related to data stream instability, the lack of benchmarks for agent-based systems, and insufficient integration of pipelines with model evaluation mechanisms. The paper proposes a conceptual classification of ELT paradigms and an outline of their adaptive evolution toward building scalable and logically coherent infrastructures. The article will be of interest to researchers in machine learning systems, LLM infrastructure developers, data platform architects, and professionals in digitalization and automation of AI training workflows.

A Review of Event-Driven Architecture Patterns Using Message Brokers in .NET
This article describes different event-driven architecture (EDA) patterns that use message brokers to implement distributed computing in .NET. This article also describes data consistency and state management techniques in a distributed system architecture. In response to the industry trend of moving from monolithic architecture to microservice architecture for scalability, agility, and resilience, this project seeks to provide a thorough basis for decision-making for the adoption of EDA patterns and message brokers (like Apache Kafka, RabbitMQ, Azure Service Bus) based on non-functional requirements and organizational maturity levels. The methodological foundation is based on a Systematic Literature Review (SLR), ensuring reproducibility, completeness, and methodological rigor of the analysis. The scientific novelty of this work lies in integrating three analytical dimensions: theoretical architectural patterns, the technological implementation of message brokers, and the practical aspects of applying them within .NET systems. The main findings emphasize that the choice of EDA patterns and broker technologies is not a search for an optimal, universal solution but a deliberate balancing of technical and organizational factors. Successful use of EDA requires maturity and experience in DevOps and observability, as well as strict adherence to idempotency principles. Therefore, the target audience for this article is software architects, developers, and researchers concerned with microservices and event-driven systems of all kinds built on .NET, as well as technical decision-makers responsible for enterprise adoption of EDA.

Safe Observability: A Framework for Automated PII Redaction from LLM Prompts in OpenTelemetry Pipelines
The proliferation of Large Language Models (LLMs) within enterprise applications has introduced a critical conflict between the goals of modern observability and the mandates of data privacy. While observability platforms provide essential, deep visibility into complex distributed systems, they inadvertently become repositories for Personally Identifiable Information (PII) when they ingest the unstructured, information-rich prompts users submit to LLMs. This leakage of sensitive data into telemetry pipelines constitutes a significant security liability and a compliance risk under regulations such as GDPR and CCPA. This paper introduces the concept of "Safe Observability," a paradigm that reconciles the need for comprehensive system insight with robust privacy protection. I propose a novel framework for achieving this through the automated redaction of PII within the OpenTelemetry (OTel) ecosystem. The core of this framework is a custom, configurable PII-Redaction Processor for the OpenTelemetry Collector, designed to act as a strategic control plane for sanitizing telemetry data in-transit. The architecture employs a hybrid PII detection methodology, combining the speed of regular expressions with the contextual accuracy of Named Entity Recognition (NER) models, implemented as a decoupled microservice. This paper details the architectural design, provides a comprehensive implementation guide for building and deploying the custom processor using the OpenTelemetry Collector Builder (OCB) and Go, and presents a rigorous evaluation of its efficacy and performance impact. The findings demonstrate that this approach offers a practically viable and architecturally sound solution for preventing PII leakage, enabling organizations to leverage the power of observability and LLMs without compromising user privacy or regulatory compliance.

Principles of Designing Monetization Systems in Free Mobile Games
The article presents a comprehensive analysis of the principles underlying the design of monetization systems in free-to-play mobile games as a distinctive phenomenon of the digital economy, where behavioral psychology, game design, and user interaction ethics converge. The relevance of the topic lies in the fact that monetization in the free-to-play format has evolved beyond a purely technical function; it has become an independent design domain that shapes the longevity and reputation of gaming ecosystems. Despite a considerable body of research, there remain substantial discrepancies in the assessment of the ethical acceptability of microtransactions, the role of artificial intelligence in offer personalization, and the balance between commercial benefit and player autonomy. The purpose of this study is to identify the key patterns behind the creation of sustainable monetization systems that maintain harmony between the developer’s economic interests and the player’s psychological comfort. Drawing on academic literature, statistical data, and the author’s own experience in designing F2P projects, a set of principles is formulated to support the development of transparent and non-intrusive monetization models. The article demonstrates that the effectiveness of such systems depends not on the number of transactions but on the quality of the trust-based relationship established between the player and the game. The author’s contribution lies in the systematization of interdisciplinary approaches—economic, cognitive, and design-oriented—and in emphasizing the importance of long-term audience retention and the integration of commercial mechanisms into the game narrative. The conclusions are of particular interest to game designers, user behavior analysts, and researchers of digital markets.

AI-Driven Capacity Forecasting for Last-Mile Logistics
The article examines the features of throughput forecasting based on artificial intelligence in the field of last-mile logistics. The relevance of the topic is driven by the fact that, under conditions of rapid growth in e-commerce and tightening consumer expectations, last-mile logistics faces unprecedented pressure, requiring hyper-accurate forecasting of operational capacity to enable a just-in-time delivery model and meet delivery deadlines without excessive costs. Traditional planning methods demonstrate their inadequacy under conditions of high demand volatility. This work describes an artificial intelligence (AI)-based framework used for forecasting daily resource requirements (personnel, transport) in large-scale logistics networks. The framework is based on a hybrid machine learning architecture that combines regression models for baseline load forecasting and the XGBoost algorithm for detecting and quantifying abnormal demand spikes. A key element of the system is a dynamic capacity buffer algorithm that, in real time, calculates the required reserve of resources to mitigate risks associated with forecast errors. The article analyzes the architecture, implementation methodology, and empirical results, and also discusses the role of such systems as a strategic tool for demand shaping.

Maturity Metrics for Engineering Teams in AI-First Application-Development Projects
This study is conducted to define a practical maturity-metrics model for AI-First engineering that links delivery and ML lifecycle to business outcomes, enabling reproducible, responsible, scalable operations across process, platform, team, and product. Comparative analysis of maturity models and delivery indicators (DORA Four Keys) combined with ML-specific metrics (retrain time, drift alerts, explainability coverage). Systematic review of MLOps practices and enterprise cases. SMART-based operationalization, automated collection via unified observability and event telemetry; explicit addition of a product plane to Microsoft’s MLOps model. Triangulation against McKinsey and DORA survey data. The model formalizes maturity across four planes—process, platform, team/culture, and product—mapped to five levels from no MLOps to fully automated operations. It integrates delivery indicators (lead time, deployment frequency, change failure rate, MTTR) with ML metrics (retrain time, drift alerts, explainability coverage) and requires SMART, automated, actionable collection. It further extends the metric set to cover generative AI and LLM-specific behavioural indicators such as factuality, instruction-following, retrieval effectiveness, safety violations and cost per useful token, and introduces repeatable proxy measures for people and culture—including knowledge diffusion, psychological safety and role-ratio tracking—so that human and organisational factors are observable and auditable. Evidence from DORA and McKinsey indicates that teams instrumenting both delivery and ML metrics achieve higher productivity, steadier SLA adherence, and reduced burnout; meanwhile, rapid AI tool uptake coexists with low trust in generated code (only 24% fully trust), underscoring an adoption–resilience gap the model addresses. Clustering metrics by change delivery, ML lifecycle, user/business value, reliability and quality, governance/ethics, and people/culture focuses investment. Operational enablers—event-based telemetry, unified observability, infrastructure as code, and SLO-prioritized alerting—support uninterrupted releases and faster recovery. The framework functions as an audit checklist and portfolio-planning instrument, translating measurements into managed, value-linked actions. Unifies DORA delivery metrics with ML lifecycle indicators across four planes, adding a product layer and operational enablers (event telemetry, IaC, SLO-prioritized alerting) to make metrics actionable for investment.

Third-Party Verification Badging for Consumer Trust: Case Study from Health and Nutrition Categories
The article examines the role of independent certification and trust-badge systems as an institutional mechanism for reducing information asymmetry in the health and nutrition segments. The relevance of the study is driven by the rapid growth of dietary supplements and functional products, accompanied by escalating consumer distrust and the rise of label skeptics. Under such conditions, external verification functions not as an optional marketing attribute but as a key quality signal that bridges costly auditing with the consumer’s simplified cognitive processing of information. The work aims to analyze the theoretical foundations and practical cases of independent badges in healthcare and nutraceuticals, as well as to assess their capacity to generate a durable trust premium. The novelty of the study lies in a comprehensive examination of certification through the lens of the economics of trust and cognitive psychology: the badge is interpreted simultaneously as a costly signal of a manufacturer’s probity and as a visual hash that facilitates consumer choice. The main results show that the display of an outward sign not only raises the subjective feeling of safety and lowers perceived risk but also translates into financial benefits, from increased readiness to pay to boosted loyalty and keeping a price premium. At the same time, the system’s weakness is revealed: the doubting of one mark can throw doubt on a whole setup, making protocol openness and reputation risk control key parts of certification strategy. The article will be helpful to researchers in the economics of trust, marketers, experts in health and nutrition, and practitioners engaged in designing and implementing independent certification systems.

Scaling MLOps in Pharma: Automating Model Deployment and Monitoring with DataRobot on AWS
This article discusses the MLOps scaling challenge amidst an increase in medical data and growing regulatory demands, which pharmaceutical companies are facing. On the AWS infrastructure, implementing DataRobot will make it possible to automate model deployment as well as monitoring and maintenance of models — without manual oversight; this traditional bottleneck usually creates another risk avenue for non-compliance with good manufacturing practice requirements. Such solution relevance is driven by an acute need for algorithm reproducibility and traceability under circumstances where pharmaceutical companies concurrently operate dozens of models. A lapse in validation or documentation can lead to clinical program delays and increased costs. The novelty here is a unified automated model registry plus deployment pipelines integrated with built-in drift/accuracy tracking and regulatorily significant audit systems. The major findings are that by automating the lifecycle, artificial intelligence stops being an artisanal collection of disconnected experiments and becomes a manageable production process. It shows how running DataRobot on AWS not only speeds up getting algorithms to the clinic but also makes sure strong FDA and GxP rules are followed with built-in version control, legally applicable report making, and data encryption. Such a strong setup where scientific change and rule order do not fight but instead help each other. The article will be of great use to drug makers, data engineers, MLOps workers, and rule managers who want to see the real use of auto ways for model work.

Enhancing Healthcare Data Interoperability with AI-Driven Synthetic Datasets Using FHIR Standards
This article addresses how one can combine AI-generated synthetic medical datasets as well as FHIR standard semantic standards and APIs to better enable cross-system interoperability between health care providers. In order to create data sets with the desired level of analytical utility, the author have as a study objective to demonstrate how the generation of synthetics in the context of FHIR resource and transport via the R5 mechanisms of profiles, subscriptions and asynchronous export to NDJSON removes both legal and technical barriers to accessing clinical data. Because data-sharing is complicated by the risk of regulatory noncompliance; a significant amount of clinical data is contained in unstructured documents; and clinical data grows at an exponential rate, the need for this type of solution has increased. This work is innovative in that it brings together three families of generative models: sequential LLM-like models, GANs and diffusion networks. Additionally, the author use a direct mapping pipeline from generative models to FHIR resources and validate profile IG and automated REST tests using built-in systems. To train the generative models on rare nosologies, and to perform load-testing, the author describe an architecture that enables private, secure access to multiple, representative cohorts, which are used to generate the synthetic data. Key Findings: (1) The use of synthetics inside the FHIR shell ensures compatibility with the current infrastructure while reducing legal barriers. (2) They also allow risk-free testing of extreme scenarios and (3) they also reduce sample bias. A rational and practical strategy for accelerating the implementation of analytics in clinics would include a strategy of generating synthetics in a continuous integration/continuous delivery (CI/CD) environment and (2) implementing mandatory validation through profile management. The author believe that the article will provide valuable assistance to medical AI developers, integration solution architects, IT service managers, and regulatory analysts.

Strategies for Database Performance Optimization in High-Load Systems: A Review of PostgreSQL and Redis Use Cases
The article presents an expanded analysis of performance-optimization strategies for database systems operating under high load, using PostgreSQL and Redis as representative examples. The study is based on comparing architectural principles of storage systems, query-planning models, mechanisms for handling concurrent operations, and the characteristics of in-memory data processing. It examines differences in DBMS behavior as workload profiles change—from read-dominant scenarios to intensive write patterns and mixed workloads. Particular attention is given to how PostgreSQL’s internal mechanisms, including cardinality estimation, plan selection, and concurrency management, respond to data-volume growth and increasing query complexity. A substantial part of the study focuses on the influence of infrastructural decisions—containerization, automatic scaling, load balancing, distributed queues, and fault-tolerance mechanisms—on the real performance of DBMSs under load. The analysis demonstrates that the stability of data-processing pipelines depends on the coherence between database-level optimizations and cloud-environment parameters, enabling the reduction of latency, improved resilience to failures, and effective operation during peak demand. The practical contribution of the work lies in identifying strategies that allow engineers to design databases and supporting infrastructure as a unified optimization system. The article will be useful for database administrators, developers of high-performance services, distributed-systems architects, cloud-platform engineers, and researchers studying data-processing mechanisms in highly loaded computational environments.
