Using Ceph in modern Cloud Installation

Abstract


To date, the use of control systems for dynamic clusters of block devices is one of the integral parts of progressive cloud installations. These technologies avoid problems in disk management and configuration, such as inconsistency, unstructured and low availability of data storage. Actual software solutions to these problems have long been known to everyone, but today, taking into account modern realities, it is necessary to select analogues of such systems that are freely distributed and have an open source code. Ceph is such software. This product has a standard set of functions of this class of programs and has a large number of unique useful methods, which makes it a worthy analogue for use in cloud installations. Thus, the purpose of this article is to popularize the use of Ceph clusters. The paper describes typical installations for running a Ceph cluster on them and how to deploy it. Testing was carried out on tasks close to real ones that users may encounter, and an analysis of the results obtained was carried out. The article will be useful, first of all, both for presenting an analogue of control systems for dynamic clusters of block devices in existing cloud installations, and for selecting a system as a solution for newly created installations. This article provides a glimpse of what Ceph can do without physically deploying the necessary infrastructure, which will save potential users time and resources.
