In practice, multi-cloud data management depth | Ansible installs OpenSDS (All in One)
With the increasing development of business data, the availability of these data decreases over time. People want to maintain the accessibility and availability of digital information of lasting value through long-term digital preservation (LTDP) to meet the challenges of outdated software and hardware, as well as accurate presentation of content.
The concept and trend of multi-cloud data management will not be discussed in detail in this article. This article focuses on technology flow. At the same time, OpenSDS came into being, an open source multi-cloud data management platform that can manage local heterogeneous storage at the same time, and is perfectly compatible with public clouds such as OpenStack, AWS, Huawei Cloud and so on.
