Technical Field

The invention relates to the technical field of cloud computing, and particularly provides a method for docking multiple storage back ends by a cloud mirror image service.

Background

Cloud platform administrators provide customers with various resources of services, including computing, storage, networks, etc., where cloud mirroring is an indispensable resource for providing customers with servers. The cloud image encapsulates solutions to customized needs that customers put forward to product providers, and also encapsulates featured products of the platform. The storage of cloud images plays a crucial role throughout the platform product chain. But current cloud mirroring services can only interface to one storage backend. Namely, the cloud mirror image can only be placed in one storage, and when the storage service is in butt joint with a plurality of storage back ends, due to the limitation of storage types, storage domains and the like, the problems that a server cannot be efficiently created for a client or the time consumption is long in the process of creating the server and the like are solved.

Cloud host: the cloud host is an important component of cloud computing in infrastructure application, is located at the bottom layer of a pyramid of a cloud computing industry chain, and is derived from a cloud computing platform. The cloud computing platform integrates three core elements of internet application: computing, storage, network, and providing a user with a public internet infrastructure service.

Cloud mirroring: is the basis for creating cloud hosts. Like the traditional mirror image, the cloud mirror image is also in a file form, and a plurality of files can be made into a mirror image file. Common image file formats are ISO, BIN, IMG, etc., which have properties similar to ZIP compressed packages. The cloud image is an image file which is provided by a cloud service manufacturer to a client and used for creating a server, the file can contain cloud products provided by the cloud service manufacturer and customized services required by the client, and the cloud image is an intuitive embodiment of the products provided by the cloud service manufacturer to the client. In more detail, the cloud mirror is a server or disk template containing software and necessary configuration, including an operating system or business data, and may further include application software (e.g., database software) and proprietary software. The mirror images are divided into public mirror images, private mirror images, shared mirror images and market mirror images.

Cloud mirroring service: the cloud mirror image service is a management service of cloud mirror images in a cloud management platform and provides life cycle management capabilities of creation, deletion, search and the like of the cloud mirror images of the mirror images. The user can flexibly apply for the elastic cloud server and the bare metal server by using public mirror images, private mirror images or shared mirror images. Meanwhile, the user can create a private mirror image through an existing cloud server or by using an external mirror image file, so that service cloud or cloud migration is realized. The mirror service has the main functions of: 1) providing a common main stream operating system common image; 2) creating a private image by an existing running cloud server or an external import mode; 3) managing common images, such as: searching according to the type/name/ID of the operating system, and checking details such as mirror image ID, system disk size and the like; checking the characteristics supported by the mirror image; 4) managing private images, such as: modifying the mirror image attribute, sharing the mirror image, copying the mirror image and the like; 5) the cloud server is created by mirroring.

Cloud mirror image back end: the back end of the cloud mirror image is the physical storage for storing the mirror image. After the cloud mirror image is uploaded, the cloud mirror image can be stored in a storage back end connected with the mirror image service in a mirror image file mode, when a cloud server is created by using the mirror image and a hard disk is started by using the cloud, the computing service and the storage service can read the mirror image file in the storage connected with the mirror image service, and the cloud resource application action is completed.

With the popularization of cloud computing, the technology is mature, the audience is increased, and the services provided by cloud computing are diversified and complicated. The cloud mirror service is an important component service in the cloud computing service, and the demand for enhancing the functions of the cloud mirror service is increasing. In the currently widely used technology, the cloud mirror service already supports multiple storage backend forms, but at present most only supports docking one of multiple backend types, and does not support docking multiple backend types simultaneously.

In actual production application, corresponding to a set of cloud management platform, the cloud mirror image service can be only connected with one storage back end, and all the customer mirror images are stored in the physical back end. However, as the user group is enlarged and the demand diversification is increased, in order to better achieve user group isolation, prevent mutual influence of users, and ensure exclusive sharing of special user resources, the platform needs to perform classification operations such as private domain division and network isolation for users. For the mirror image service, although the private mirror image can be guaranteed to be used by a special user, for the public mirror image, the partition can cause that downloading operation is needed when the mirror image is read in a cross-domain mode, so that projects for creating a cloud hard disk and a cloud host from the cloud mirror image are limited by network transmission speed, often, due to the ineffectiveness factors such as network delay and large cloud mirror image files, the cloud mirror image acquisition time is too long, and the storage service, the computing service wait for the cloud hard disk and the cloud host to finish creating actions overtime, so that resources cannot be normally provided for the user.

Aiming at another situation, the cloud mirror image service is tried to be directly connected to the storage service, at the moment, the available domain division of the cloud mirror image service is synchronous with the storage service, and the defect that mirror image files are cached across available domains can be avoided. However, the direct docking of the storage service may cause a problem that a cloud image of the storage service across a network region cannot be obtained, and the cloud image still needs to be cached when the storage service crosses a physical storage back end, that is, a problem that the creation of a cloud host and a cloud hard disk fails is still not solved.
