The DREAM project was funded more than 3 years ago to design and implement a next-generation ESGF (Earth System Grid Federation [1]) architecture which would be suitable for managing and accessing data and services resources on a distributed and scalable environment. In particular, the project intended to focus on the computing and visualization capabilities of the stack, which at the time were rather primitive. At the beginning, the team had the general notion that a better ESGF architecture could be built by modularizing each component, and redefining its interaction with other components by defining and exposing a well defined API. Although this was still the high level principle that guided the work, the DREAM project was able to accomplish its goals by leveraging new practices in IT that started just about 3 or 4 years ago: the advent of containerization technologies (specifically, Docker), the development of frameworks to manage containers at scale (Docker Swarm and Kubernetes), and their application to the commercial Cloud. Thanks to these new technologies, DREAM was able to improve the ESGF architecture (including its computing and visualization services) to a level of deployability and scalability beyond the original expectations.

地球系统网格高级管理 (DREAM) 的分布式资源

DREAM 项目在 3 多年前获得资助，旨在设计和实施下一代 ESGF（地球系统网格联盟 [1]）架构，该架构将适用于在分布式和可扩展环境中管理和访问数据和服务资源。特别是，该项目旨在专注于堆栈的计算和可视化能力，这在当时是相当原始的。一开始，团队有一个普遍的想法，即可以通过模块化每个组件来构建更好的 ESGF 架构，并通过定义和公开定义良好的 API 来重新定义其与其他组件的交互。尽管这仍然是指导工作的高级原则，但 DREAM 项目能够通过利用大约 3 或 4 年前开始的 IT 新实践来实现其目标：容器化技术（特别是 Docker）的出现，大规模管理容器的框架（Docker Swarm 和 Kubernetes）的开发，以及它们在商业云中的应用。得益于这些新技术，DREAM 能够将 ESGF 架构（包括其计算和可视化服务）改进到超出最初预期的可部署性和可扩展性水平。
