In today’s times, people demand fast, stable, and reliable applications. Therefore, it is essential to choose the right software architecture before implementing functionalities adopted in the project. The monolithic architecture is implemented as a single unit, integrating all functionalities within a single codebase. In contrast, the microservice architecture decomposes the application into several independent services, each responsible for a specific business logic. Key factors such as scalability, fault tolerance, and data consistency are analyzed. Performance metrics, simplicity, flexibility, and the challenges of implementing and maintaining each architecture are gathered and compared. This study offers valuable insights into the practical implications of choosing between monolithic and microservice architectures, especially in the context of applications. It serves as a comprehensive guide for software developers to make informed decisions when designing scalable and reliable systems.

This paper provides a comprehensive overview of the preparation and deployment of secure Over-The-Air (OTA) updates for embedded devices. In the era of intelligent devices, the need for remotely updating software and firmware has become increasingly prevalent. This paper discusses the principles of OTA updates, focusing on the various types used in the field of embedded devices and the complications that need to be resolved for a successful process. Furthermore, it delves into the theoretical description of OTA updates, security mechanisms, and practical implementation. The paper also highlights the main benefits of OTA updates, such as convenience, security, scalability, reduced maintenance costs, and improved performance. Additionally, it addresses the challenges and issues associated with OTA updates, including update reliability, security risks, compatibility, network propagation, and integrity and warranty implications. Overall, this paper serves as a valuable resource for understanding the complexities and importance of OTA updates in the realm of embedded devices.

The advantages of using composite materials are currently manifested in various industries. This creates space for their even greater application in the automotive industry. Car manufacturers strive to constantly reduce the weight of the car, increasing its durability and safety at the same time. Car consumption and associated emissions are closely monitored. Composite materials therefore offer a range of properties that meet today’s automotive requirements to a large extent.

the theory of cumulative fuel consumption has been presented. The example of interurban bus research results have shown the way of getting to mathematical model of cumulative fuel consumption and the intensity of cumulative fuel consumption. The high value of pres- cience quotients is not a case- similar values were obtained in various different cases.
