Cloud infrastructures are highly favoured as a computing delivery model worldwide, creating a strong societal dependence. It is therefore vital to enhance their resilience, providing persistent service delivery under a variety of conditions. Cloud environments are highly complex and continuously evolving. Additionally, the plethora of use-cases ensures requirements for persistent service delivery vary. As a contribution to knowledge, this work surveys resilience techniques for cloud environments. We apply a novel perspective using a layered model of traditional and emerging cloud paradigms. Works are then classified according to the Resilinets model. For each layer, the most common techniques with limitations are derived including an actor’s strength in influencing resilience in the cloud with each technique. We conclude with some future challenges to the field of resilient cloud computing.

云计算中的弹性

云基础设施作为一种计算交付模式在全球范围内受到高度青睐，从而产生了强烈的社会依赖性。因此，增强他们的弹性，在各种条件下提供持续的服务交付至关重要。云环境高度复杂且不断发展。此外，过多的用例确保了对持久服务交付的要求各不相同。作为对知识的贡献，这项工作调查了云环境的弹性技术。我们使用传统和新兴云范例的分层模型应用新颖的视角。然后根据 Resilinets 模型对作品进行分类。对于每一层，都导出了最常见的具有局限性的技术，包括参与者在使用每种技术影响云中的弹性方面的实力。
