Bitrix24 on-premise edition is a sophisticated and comprehensive product. To host it, it is necessary to rent a virtual or physical server with resources corresponding to the number of system users in your company.
This page contains the recommended by Bitrix24 technical requirements for the server. In practice, depending on your needs, you can rent somewhat more modest server configurations. When purchasing or renewing Bitrix24 licenses via our company, we offer free consultations to help you choose the best server configuration.
