From the advent of Grid technology – as the new paradigm of distributed computing – to the current days of Cloud computing models, the continuous need of new tools and services to match the scientific community requirements has been addressed in Europe through dedicated software development projects for e–Infrastructure creation, operation and management. This work presents the most significant software quality breakthroughs obtained in one of such projects, INDIGO–DataCloud, the main challenges and barriers confronted throughout the lifespan of the project, and how they were partially or totally overcome. The knowledge base established throughout the last 15 years of diverse software development initiatives in Europe for sustaining distributed research e-Infrastructures, supported by the advances in the area of software engineering, definitely contributed to improve the quality and reliability of the software delivered, and consequently, the operational stability of the European e–Infrastructures. INDIGO–DataCloud project is a good evidence of such insights, where, unlike the preceding trend found in past projects, the enforcement of Software Quality Assurance practices has been present since the very early stages of the software lifecycle.

INDIGO-DataCloud项目中的软件质量保证：支持欧洲研究电子基础设施的软件工程实践的不断演变

从网格技术的出现（作为分布式计算的新范例）到当今的云计算模型，欧洲已经通过针对e的专用软件开发项目满足了对满足科学界要求的新工具和服务的持续需求。 –基础架构的创建，运营和管理。这项工作展示了在其中一个项目INDIGO–DataCloud中获得的最重要的软件质量突破。，整个项目生命周期中面临的主要挑战和障碍，以及如何部分或完全克服这些挑战和障碍。在过去的15年中，在欧洲各种软件开发计划中建立了知识库，以维持分布式研究电子基础设施，在软件工程领域的进步的支持下，知识库无疑有助于提高所交付软件的质量和可靠性，因此，欧洲电子基础设施的运营稳定性。INDIGO–DataCloud项目很好地证明了这种见解，与以往项目中发现的趋势不同，自软件生命周期的早期阶段就开始实施软件质量保证实践。
