Abstract: Recently, the development of communication technologies, including the Internet of Things technology, has allowed to significantly automate and make people's lives easier. Internet of Things technologies are being implemented in various applications from agriculture to industrial sectors, from smart homes to smart cities. Due to this popularity, the number of smart devices is growing rapidly. Multiple forecasts already represent numbers of up to several billion devices in the next 5 years. Thus, the task of providing energy consumption for so many devices has become a priority in the development of Internet of Things. In order to study energy consumption, the simplest Internet thing based on RFID technology was tested, which allowed to calculate the service life of the battery located in the case of the radio frequency identification tag. Research subject. This article is about testing the power consumption of a typical Internet of Things device — RFID tags. Method. The studies are based on experimental methods, as well as statistical processing of measurement results.

Abstract: Scalability is a fundamental characteristic of any cloud-based microservice architecture. In the modern world, any service that is designed to provide services to a wide number of consumers should be characterized by good scalability and fast response speed. Potential users will never want to suffer constant errors, lost requests, denial of service, and other problems associated with a lack of service performance. Research subject: load balancing system in query processing and interaction within the cloud microservice architecture. Method: implementing additional elements in the cloud microservice architecture to provide load balancing. Core results: a number of popular load balancing algorithms in cloud microservice structures are compared, and options for upgrading in cloud microservice architectures for traffic balancing at different levels of the OSI model are proposed. Practical relevance: the study solved the problem of increasing the volume of processed requests without using a proportional increase in hardware resources.
Keywords: Micro service architecture, virtualization, balancing, high-load applications, dynamic resource scaling.
