Summary: The large-scale, high availability, high timeliness, high accuracy and other requirements of large-scale Internet companies/financial industry scenarios will challenge the existing federated or distributed storage Prometheus solutions. This article will introduce how the Baidu Cloud native team builds the monitoring capability of large-scale online business transactions based on Prometheus according to the scenario needs of the financial industry and combined with the practical application experience in Baidu.
2. Exploration and Practice of Service Mesh in ICBC
Summary: As a new microservice architecture, Service Mesh is considered to have a good development prospect because of its flexible architecture and strong universality. Industrial and Commercial Bank of China (hereinafter referred to as ICBC) took the initiative to explore the field of service grid, started the pre research work of service grid technology in 2019, and built the service grid platform in 2021 after in-depth research and practice of service grid technology. The integrated development of service grid and existing microservice architecture helps ICBC to transform its application architecture to distributed and service-oriented, and bears the core banking system of the future open platform.
