The invention discloses an OpenStack memory optimization method and system. The invention provides the OpenStack memory optimization method. The method comprises the following processing steps that S1, OpenStack takes Ceph RBD as a uniform storage rear end of mirror image service Glance, calculation service Nova and block memory service Cinder; and S2, the OpenStack stores mirror images of the mirror image service Glance to the Ceph RBD in a layered mode, thereby forming a mirror image pool containing system mirror images and software mirror images, and the OpenStack is in support of starting virtual machines in the system mirror images, carrying out whole content backup on the virtual machines, starting the virtual machines in the software mirror images and carrying out incremental backup on the virtual machine, thereby satisfying different user demands. The invention also provides the OpenStack memory optimization system. According to the method and the system, the OpenStack uniform block memory system is established based on the Ceph RBD, on this basis, the mirror images are stored in the layered mode, the memory space is effectively saved, the data memory reliability is improved, the maintenance cost is reduced, and the different user demands are satisfied.
Description
technical field [0001] The present invention relates to the field of cloud computing, in particular to an OpenStack storage optimization method, and also to an OpenStack storage optimization system. Background technique [0002] Cloud computing is a new computing model developed from virtualization technology and distributed computing. Transformation" has become a new development trend. The architecture model of cloud computing is mainly divided into three layers: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS), which can provide users with a comprehensive set of services ranging from IT resources to software services, network applications, and data storage. A delivery platform for different types of services. [0003] Ceph is an open source unified distributed storage system and one of the most mainstream open source storage projects. Ceph has outstanding advantages. For example, it can provide three storage access method...
