HYBRID CLOUD INFRASTRUCTURE VS. ON-PREMISES: SECURITY, PERFORMANCE, AND COST PERSPECTIVES

Аннотация

This article analyzes the differences and features of hybrid cloud infrastructure and on-premises deployment models in terms of security, performance, and cost. The advantages and disadvantages of both models are considered, and recommendations are made on which infrastructure model is more effective for organizations. The article highlights the main factors that are important in choosing a modern IT infrastructure. Keywords: Hybrid cloud infrastructure, security, performance, cost, cloud services. In the field of information technology, organizations face many choices when forming their infrastructure. On-premises deployments are based on the traditional method of managing all resources on-site. Cloud deployments, on the other hand, store and manage data and applications with the help of external service providers. Hybrid cloud infrastructure combines these two models, providing maximum flexibility and security. This article compares these infrastructure types in terms of security, performance, and cost. Cloud technologies are widely used today in various fields, including personal and professional purposes. Due to their efficiency and convenience, they are fundamentally changing the work processes in many industries. Below are examples of the use of cloud technologies in some of the main areas. In the field of education: Cloud services make the educational process more interactive and free. Students and teachers can easily communicate remotely. With the help of cloud platforms, online courses and lectures have become much more convenient. At the same time, education is available 24 hours a day, and students can Выпуск журнала №-26 Часть–8_ Май –2025 190 MODERN EDUCATION AND DEVELOPMENT continue their studies at any time and place. This helps to improve the quality of education and improve the level of knowledge of students. In the field of healthcare: Currently, about 35% of healthcare organizations prefer to store their data in the cloud. This helps to further optimize medical processes. For example, it becomes easier to provide an individual approach to patients, and doctors can quickly monitor the condition of patients. Health information stored in the cloud is always available to specialists, which helps to provide quick consultations and improve collaboration between doctors. This results in reduced waiting times for patients and increased quality of treatment. In trade: Cloud technologies are also widely used in the trade and retail sectors. They help businesses expand their activities, quickly access large databases, analyze the market, and create online trading platforms. At the same time, cloud technologies make trade relations between sellers and customers more efficient and convenient, which simplifies trading processes and allows you to meet customer needs faster. In business processes: Cloud architecture offers a wide range of opportunities for optimizing corporate operations. The ability to quickly expand and manage computing power allows companies to quickly grow their business and maintain a flexible pricing policy. In addition, cloud technologies allow employees to serve customers from anywhere in the world, which supports global operations. And data is available 24 hours a day, 7 days a week, and business processes continue uninterrupted. In today's competitive business environment, organizations are under intense pressure to effectively manage their information technology (IT) resources, regardless of their position in the market. Operating entirely on traditional, local (on-premises) infrastructure is becoming less efficient due to its rigidity and limited flexibility in the rapidly changing conditions of the digital era. At the same time, moving to the full cloud is also a difficult task for many organizations. Data confidentiality, legal restrictions, and large investments already made in on-premises systems make this process difficult. The hybrid cloud model, on the other hand, combines the best of both worlds and is seen as a perfect solution. This approach allows organizations to keep their Выпуск журнала №-26 Часть–8_ Май –2025 191 MODERN EDUCATION AND DEVELOPMENT critical systems and data under local control, while at the same time opening the way to take advantage of the flexibility, cost savings, and efficiency benefits of cloud computing. Hybrid cloud technology has been widely discussed recently, as many organizations realize that this approach can meet many of the needs of their IT departments. Combining local and cloud resources allows organizations to maximize the use of their IT assets and quickly adapt their operations to market conditions. However, the hybrid cloud model is not without its own challenges. Therefore, the decision to implement it should be carefully studied in order to maximize the benefits for each organization. This article will provide the reader with detailed information about the concept of hybrid cloud computing, its advantages and disadvantages, a
