Cloud computing heavily relies on virtualization, as with cloud computing virtual resources are typically leased to the consumer, for example as virtual machines. Efficient management of these virtual resources is of great importance, as it has a direct impact on both the scalability and the operational costs of the cloud environment. Recently, containers are gaining popularity as virtualization technology, due to the minimal overhead compared to traditional virtual machines and the offered portability. Traditional resource management strategies however are typically designed for the allocation and migration of virtual machines, so the question arises how these strategies can be adapted for the management of a containerized cloud. Apart from this, the cloud is also no longer limited to the centrally hosted data center infrastructure. New deployment models have gained maturity, such as fog and mobile edge computing, bringing the cloud closer to the end user. These models could also benefit from container technology, as the newly introduced devices often have limited hardware resources. In this survey, we provide an overview of the current state of the art regarding resource management within the broad sense of cloud computing, complementary to existing surveys in literature. We investigate how research is adapting to the recent evolutions within the cloud, being the adoption of container technology and the introduction of the fog computing conceptual model. Furthermore, we identify several challenges and possible opportunities for future research.

容器化云中的资源管理:现状与挑战

云计算在很大程度上依赖于虚拟化,因为云计算虚拟资源通常出租给消费者,例如作为虚拟机。有效管理这些虚拟资源非常重要,因为它对云环境的可扩展性和运营成本都有直接影响。最近,由于与传统虚拟机相比开销最小且提供的可移植性,容器作为虚拟化技术越来越受欢迎。然而,传统的资源管理策略通常是为虚拟机的分配和迁移而设计的,因此出现了如何调整这些策略以管理容器化云的问题。除此之外,云也不再局限于集中托管的数据中心基础设施。新的部署模型已经成熟,例如雾和移动边缘计算,使云更接近最终用户。这些模型也可以从容器技术中受益,因为新引入的设备通常具有有限的硬件资源。在本次调查中,我们概述了云计算广义上的资源管理的当前技术水平,作为对现有文献调查的补充。我们调查研究如何适应云中最近的演变,即容器技术的采用和雾计算概念模型的引入。此外,我们确定了未来研究的几个挑战和可能的机会。这些模型也可以从容器技术中受益,因为新引入的设备通常具有有限的硬件资源。在本次调查中,我们概述了云计算广义上的资源管理的当前技术水平,作为对现有文献调查的补充。我们调查研究如何适应云中最近的演变,即容器技术的采用和雾计算概念模型的引入。此外,我们确定了未来研究的几个挑战和可能的机会。这些模型也可以从容器技术中受益,因为新引入的设备通常具有有限的硬件资源。在本次调查中,我们概述了云计算广义上的资源管理的当前技术水平,作为对现有文献调查的补充。我们调查研究如何适应云中最近的演变,即容器技术的采用和雾计算概念模型的引入。此外,我们确定了未来研究的几个挑战和可能的机会。补充现有的文献调查。我们调查研究如何适应云中最近的演变,即容器技术的采用和雾计算概念模型的引入。此外,我们确定了未来研究的几个挑战和可能的机会。补充现有的文献调查。我们调查研究如何适应云中最近的演变,即容器技术的采用和雾计算概念模型的引入。此外,我们确定了未来研究的几个挑战和可能的机会。
