description: In this final qualifying work, the infrastructure for the future large project, which I plan to develop further, will be developed. The project itself will act as a guarantor between the purchase and sale of film content licenses using blockchain technology. The service will consist of many independent components. Any modern service starts with a website, so I chose the React library to create my user interface, because now this library is the most popular, and as it turned out to be very easy to learn and raise new projects. Since the service will receive and return data, it will need a server that will communicate with the database and perform complex operations. I chose Node JS, a software platform based on the V8 engine, the platform is suitable for quickly writing an API for a service in JavaScript. For data storage, I chose the PostgreSQL object-relational database management system, it is very convenient to store data with it. And, for the automated management of funds in the form of guarantors, I will use blockchain technology based on Ethereum. To interact with the blockchain itself, you need to write special programs - smart contracts, I will write them in a special Solidity language. Any complex service will eventually need to be released to the global Internet, cloud technologies in the form of Docker and a rented virtual machine in Yandex Cloud will help me with this. As a result, my service will be launched in the Yandex Cloud virtual machine, in which there will be my images of multiple containers from Docker, NGINX will manage communication and distribution of networks to the outside, a site that accesses the server API, smart contracts will be created on the server side and send queries to the database.
