Abstract

Multi-cloud solutions are becoming increasingly popular among enterprises and, today, it is easy to find organizations that use resources and services belonging to two or more cloud providers. It is well-known that the adoption of a multi-cloud infrastructure provides several advantages: it limits vendor lock-in and/or dependence on a single provider, enables cost reduction, grants the access to a wide variety of services and computational resources and allows the exploitation of the geographical location of the servers (e.g., to be consistent with data compliance policies). These advantages, however, have a cost in terms of greater complexity in resources' configuration and management: e.g., security policies have to be adapted and made consistent among all the different cloud providers. This complexity implies that most of the companies that use a multi-cloud infrastructure manage the resources belonging to different providers as independent and autonomous, exploiting only a portion of the advantages that could be benefited if those resources were used in an integrated and optimized way. In this paper, we will describe and discuss some of the aspects related to the inter-networking among resources belonging to multiple providers, a necessary and fundamental step towards a strong integration among different clouds.
多云环境下用户应用管理成本研究
多云解决方案在企业中越来越流行,今天,很容易找到使用属于两个或更多云提供商的资源和服务的组织。众所周知,采用多云基础架构提供了几个优势:它限制了供应商锁定和/或对单一提供商的依赖,能够降低成本,允许访问各种服务和计算资源,并允许利用服务器的地理位置(例如,与数据遵从性策略保持一致)。然而,这些优势的代价是资源配置和管理更加复杂:例如,必须在所有不同的云提供商之间调整并保持一致的安全策略。这种复杂性意味着,大多数使用多云基础设施的公司将属于不同提供商的资源作为独立和自主的方式进行管理,只利用了如果以集成和优化的方式使用这些资源可能会受益的部分优势。在本文中,我们将描述和讨论与属于多个提供商的资源之间的互连网络相关的一些方面,这是实现不同云之间强大集成的必要和基本步骤。
