Abstract

Dynamic On Demand Analysis Service (DODAS) is a Platform as a Service tool built combining several solutions and products developed by the INDIGO-DataCloud H2020 project. DODAS allows to instantiate on-demand container-based clusters. Both HTCondor batch system and platform for the Big Data analysis based on Spark, Hadoop etc, can be deployed on any cloud-based infrastructures with almost zero effort.  DODAS acts as cloud enabler designed for scientists seeking to easily exploit distributed and heterogeneous clouds to process data. Aiming to reduce the learning curve as well as the operational cost of managing community specific services running on distributed cloud, DODAS completely automates the process of provisioning, creating, managing and accessing a pool of heterogeneous computing and storage resources. DODAS was selected as one of the Thematic Services that will provide multi-disciplinary solutions in the EOSC-hub project, an integration and management system of the European Open Science Cloud starting in January 2018. The main goals of this contribution are to provide a comprehensive overview of the overall technical implementation of DODAS, as well as to illustrate two distinct real examples of usage: the integration within the CMS Workload Management System and the extension of the AMS computing model.

DODAS:如何有效利用异构云进行科学计算
动态按需分析服务(DODAS)是一个平台即服务工具,结合了INDIGO-DataCloud H2020项目开发的几种解决方案和产品。DODAS允许实例化基于按需容器的集群。无论是HTCondor批处理系统,还是基于Spark、Hadoop等的大数据分析平台,都可以毫不费力地部署在任何基于云的基础设施上。DODAS作为云推动者,专为寻求轻松利用分布式和异构云来处理数据的科学家而设计。为了减少学习曲线以及管理运行在分布式云上的社区特定服务的运营成本,DODAS完全自动化了供应、创建、管理和访问异构计算和存储资源池的过程。DODAS被选为主题服务之一,将在欧洲开放科学云的集成和管理系统EOSC-hub项目中提供多学科解决方案,该项目将于2018年1月启动。本文的主要目标是全面概述DODAS的总体技术实现,并举例说明两个不同的实际使用示例:CMS工作负载管理系统中的集成和AMS计算模型的扩展。
