In order to facilitate understanding of the technical solutions in the embodiments of the present application, the following first explains some terms related to the embodiments of the present application:

object storage service (object storage service, OBS): the cloud storage system is an object-based mass storage service of public cloud, and provides mass, safe, high-reliability and low-cost data storage capacity for tenants of the public cloud.

Data buckets (also referred to as buckets): the object storage is a container for storing objects in the OBS, provides a flattened storage mode based on a data bucket and the objects, and all the objects in the data bucket are in the same logic level, so that a multi-level tree directory structure in a file system is removed. Each data bucket has the own storage category, access right, belonging area and other attributes, and tenants can create data buckets with different storage categories and access rights in different areas and configure more advanced attributes to meet the storage requirements of different scenes.

Cloud management platform: pages related to public cloud services can be provided for tenants to remotely access the public cloud services, the tenants can log in the cloud platform on the public cloud access page through a pre-registered account number and password, and after logging in successfully, corresponding public cloud services such as an OBS service, a virtual machine service, a container service and the like are selected and purchased on the public cloud access page, and for the OBS service, the tenants can further configure the OBS service through a configuration interface or an application programming interface (application programming interface, API) provided on the public cloud access page, such as creating a data bucket, configuring access policies of the data bucket, uploading objects from computing equipment local to the tenants through the Internet, and the like, and operating on the data bucket.

Object storage device (object storage device, OSD): the basic storage unit of the object storage system is arranged on a physical disk, in particular to a storage space with a fixed size of the physical disk, and the object storage system manages the physical disks of a plurality of servers (such as servers of a cloud data center) in an OSD form. In order to realize communication between the existing cloud management platform and the client node, one way is that the client node configures a fixed IP address and opens a fixed interface for the cloud management platform to call, and the other way is that the cloud management platform configures the fixed IP address and opens the fixed interface for the client node to connect.

In view of this, the embodiment of the present application provides a communication method based on a cloud computing technology, and builds communication capability between a client node and a cloud management platform based on an infrastructure providing a data bucket in an object storage service, where the client node and the cloud management platform do not need to provide a fixed API to the outside, and network security is high.

A tenant may log in on a cloud management platform by using an account number, a configuration interface or an API on a public cloud access page provided by the cloud platform may create a plurality of data buckets, the sum of the number and the size of objects stored in each data bucket is not limited, the tenant does not need to consider the expandability of data, the OBS is a service based on REST (Representational STATE TRANSFER) style and hypertext transfer protocol (hypertext transport protocol, HTTP) and hypertext transfer security protocol (Hypertext Transfer Protocol Secure, HTTPs) protocols, the tenant may locate data bucket resources through uniform resource locators (Uniform Resource Locator, URLs, which are also called domain names) or IP addresses, the relation between the data buckets and the objects in the OBS is shown in fig. 1, fig. 1 is a logical architecture diagram of an object storage service, as shown in fig. 1, each data bucket may include a plurality of objects, for example, a first data bucket shown in fig. 1 includes an object 1, an object 2, an object 3 and an object 4, and a second data bucket includes an object 5, an object 6, an object 7 and an object 8. Objects between the data buckets are isolated from each other, and the tenant remotely purchases an object storage service by operating the client node 20, the object storage service providing the data buckets to the tenant, in particular, a domain name or an IP address of the data bucket may be provided, which the tenant may operate the client node 20 to access so that data may be uploaded to the data buckets, and data may be downloaded from the data buckets, wherein the uploaded data is stored in the data buckets in an object manner.

An object is a basic unit of data storage in an OBS, and an object is actually an aggregate of data of one file and its related attribute information (metadata). The data uploaded to the OBS by the tenant is stored in the data bucket in the form of an object. The object includes three parts of Key value (Key), metadata (Metadata), and Data (Data). The key, i.e. the name of the object, is, for example, a character sequence encoded by UTF-8 and having a length greater than 0 and not more than 1024, and each object in a data bucket has a unique object key. Metadata, i.e., description information of the object, includes system metadata and tenant metadata, which are uploaded into the object storage service in the form of Key-Value pairs (Key-values). The system metadata is automatically generated by the object storage service, and is used when processing the object data, including Date (Date), content-length (Content-length), last-time modification (Last-modification), MD5 encrypted Content (Content-MD 5), and the like. Tenant metadata is specified by the tenant when uploading an object to a data bucket, and is tenant-customized object description information. The data is the data content uploaded by the tenant.

When the tenant uploads the object, the storage category of the object can be designated, and if the storage category is not designated, the storage category of the tenant is consistent with the storage category of the data bucket by default. After uploading, the storage class of the object may be modified, the data bucket may be accessed through the client node 20, the client node 20 may be, for example, a dedicated client provided by a browser or a cloud management platform of a tenant locally used, for example, the tenant may access the data bucket through a browser provided in a local computing device, after the input account is verified, the tenant may upload the object into the data bucket using the browser, or delete the object in the data bucket, where the local computing device accesses the internet (public network). For example, local computing devices include, but are not limited to: car machine, cell-phone, personal computer, intelligent wearing equipment, intelligent household electrical appliances, intelligent medical instrument, intelligent sports apparatus etc..

Further, client node 20 may also be located in a virtual machine, container, and server (e.g., bare metal server) provided by a public cloud service, with access to the data buckets via a public cloud internal network.

It should be noted that any device that can access a data bucket through the internet or public cloud intranet may be referred to as a client node 20 of an embodiment of the present invention. FIG. 2 is a schematic diagram of an object storage system according to an embodiment of the present invention.

In the embodiment shown in fig. 2, the object storage system includes a cloud management platform 10 and an infrastructure 11. The cloud management platform 10 is in communication with an infrastructure 11. A plurality of cloud data centers may be provided in the infrastructure 11, with an exemplary plurality of cloud data centers including cloud data center dc1 provided in area ar1 and cloud data center dc2 provided in area ar 2. Cloud data center dc1 and cloud data center dc2 may each include a plurality of servers on which virtual machines or containers provided for the tenants to use may be run, and the disks of the servers may be set to be data volumes as data buckets provided for the tenants to use by cloud management platform 10.

In this architecture, a tenant may create a data bucket b1 and a data bucket b2 in the cloud management platform 10 in advance, the data bucket b1 being disposed in the area ar1, and the data bucket b2 being disposed in the area ar2. Let the domain name of data bucket b1 be bucket1.Region1.Com, the IP address of data bucket b1 be IP1, the domain name of data bucket b2 be bucket2.Region2.Com, and the IP address of data bucket b2 be IP2.

Wherein, in the domain name bucket1.Region1.Com of the data bucket b1, bucket1 is the bucket name of the data bucket b1, and region1 is the region where the data bucket b1 is located. Similarly, bucket2 in the domain name bucket2.Region2.Com of data bucket b2 is the bucket name of data bucket b2, and region2 is the region in which data bucket b2 is located.

Specifically, after the creation of the data bucket b1 is completed, the cloud management platform 10 may register the corresponding relationship 1 between the public network domain name bucket1.Region1.Com and the public network IP1 in the domain name service node 30, and register the corresponding relationship 2 between the public network domain name bucket2.Region2.Com and the public network IP2 in the domain name service node 30 after the creation of the data bucket b2 is completed.

Alternatively, the domain name service node 30 may be jointly implemented by at least one top-level domain name service node and a plurality of secondary domain name service nodes disposed in different areas, where in the above-mentioned domain name registration process, the top-level domain name service node records a correspondence between region1 and the secondary domain name service node disposed in area ar1 (the secondary domain name service node may also record a correspondence between socket 1 and IP 1), and records a correspondence between region2 and the secondary domain name service node disposed in area ar2 (the secondary domain name service node may also record a correspondence between socket 2 and IP 2). The cloud management platform 10 may also be disposed in the cloud data center dc1 or the cloud data center dc2, where the cloud data center dc1 and the cloud data center dc2 are cloud data centers to which the cloud service provider belongs, and further, the cloud management platform 10 may also be disposed in other cloud data centers of the cloud service provider.

As shown in fig. 3, the server (for example, the server in the cloud data center dc1 or the cloud data center dc 2) includes a software layer and a hardware layer, the hardware layer includes a disk controller 2015, a physical network card 2016, a physical disk d1 and a physical disk d2, the software layer includes an OSD control unit 2011 and an operating system 2012, the OSD control unit 2011 runs on the operating system 2012, the operating system 2012 includes a disk driver 2013 and a physical network card driver 2014, the cloud management platform 10 may communicate with the OSD control unit 2011 through the physical network card 2016, the OSD control unit 2011 controls the disk controller 2015 through the disk driver 2013 to set the physical disk d1 and the physical disk d2 as a plurality of OSDs, and the cloud management platform 10 notifies the OSD control unit 2011 to create the data bucket b1 after receiving a creation instruction of the data bucket b1, at this time, the OSD control unit 2011 sets the OSDs 1-3 as the data bucket b1.

Fig. 4 is a flowchart illustrating steps of a communication method based on a cloud computing technology according to an embodiment of the present application. The order of the steps in the flow diagrams may be changed, and some steps may be omitted, according to different needs. In this embodiment, the communication method based on the cloud computing technology may be applied to the cloud management platform 10, where the cloud management platform 10 is configured to provide the object storage service to the tenant and manage the infrastructure 11 for providing the data bucket in the object storage service, and the communication method based on the cloud computing technology may include:

s41, the cloud management platform 10 receives information for the client node 20 input by the tenant.

In some embodiments, client node 20 is disposed outside of infrastructure 11 and accesses the public network. The information for client node 20 may include data, instructions, or data + instructions. For example, the data may be a software upgrade package, backup data, etc., and the instruction may be an upgrade instruction, a backup instruction, etc., which is not limited in the present application.

S42, the cloud management platform 10 writes the information for the client node 20 to the data bucket.

In some embodiments, the data bucket is provided with a public network oriented access address for instructing the client node 20 to obtain information for the client node 20 from the data bucket. For example, the access address may be a public network IP address or a public network domain name registered on a public network domain name server (e.g., domain name service node 30 shown in fig. 3).

For example, a tenant may refer to a user of client node 20, such as where client node 20 is a vehicle, and a tenant may be a user of a vehicle. Assuming that the software installed in the vehicle is to be upgraded, the tenant may log in the object storage service of the cloud management platform 10 to create a data bucket (e.g., data bucket b 1), upload a software upgrade package in the data bucket b1, and the vehicle may access the data bucket b1 based on the access address, and download the software upgrade package from the data bucket b1 for performing the software upgrade. Of course, the client node 20 may be other terminal devices, or servers, virtual machines, containers, etc. of the cloud data center.

In some embodiments, to promote security of information written into the data bucket, the data bucket may verify whether the visitor (cloud management platform 10 or client node 20) has access rights based on the access credentials, and allow the visitor to perform a read/write operation on the data bucket after confirming that the visitor has access rights. For example, cloud management platform 10 may write information for client node 20to data bucket b1 based on a first access credential indicating that cloud management platform 10 has the right to access data bucket b1, client node 20 obtaining information for client node 20 written by cloud management platform 10 from data bucket b1 based on a second access credential indicating that client node 20 has the right to access data bucket b 1. For example, the first access credential and the second access credential may be keys, passwords, tokens, and the like.

S43, the cloud management platform 10 accesses the data bucket, obtains the execution result of the information uploaded to the data bucket by the client node 20 from the data bucket, and provides the execution result to the tenant.

In some embodiments, after the client node 20 obtains the information from the data bucket, the obtained information may be executed and the execution result of the information may be uploaded to the data bucket, and the cloud management platform 10 may obtain the execution result of the client node 20 uploaded to the data bucket from the data bucket by accessing the data bucket and provide the execution result to the tenant. For example, client node 20 downloads a software upgrade package from a data bucket for a software upgrade. After the software upgrade is successful or fails, the client node 20 may upload the software upgrade success information or the software upgrade failure information to the data bucket, and the cloud management platform 10 may obtain a software upgrade result of the client node 20 by accessing the data bucket, and provide the software upgrade success information or the software upgrade failure information to the tenant (for example, display the software upgrade success information or the software upgrade failure information through a page), so that the tenant may timely learn the software upgrade result of the client node 20.

In some embodiments, the cloud management platform 10 may periodically access the data bucket based on the first access credential to obtain the execution result of the information reported to the cloud management platform 10 by the client node 20 in time. For example, the cloud management platform 10 may access the data bucket at intervals of a preset time after writing the information for the client node 20 into the data bucket, and the preset time may be set according to actual requirements, which is not limited in the present application. The cloud management platform 10 may also estimate a time period (e.g., a first time period) required for the client node 20 to execute the information, and access the data bucket at preset time intervals after the first time period after writing the information for the client node 20 to the data bucket.

In some embodiments, a one-to-many management mode is typically used between the cloud management platform 10 and the client nodes 20, and it is assumed that the cloud management platform 10 can manage N client nodes 20, where N is a positive integer. The tenants of N client nodes 20 create a data bucket at the infrastructure 11 that has a one-to-one correspondence with the N client nodes. Assuming that the tenant of the first client node creates a data bucket b1 at infrastructure 11, the tenant of the second client node creates a data bucket b2 at infrastructure 11. The cloud management platform 10 may write first information for a first client node to a data bucket corresponding to the first client node, i.e., data bucket b1, and second information for a second client node to a data bucket corresponding to the second client node, i.e., data bucket b2. The cloud management platform 10 obtains the execution result for the first information uploaded by the first client node by accessing the data bucket b 1. The cloud management platform 10 may further obtain an execution result for the second information uploaded by the second client node by accessing the data bucket b2.

In some embodiments, N client nodes 20 may also share a single data bucket. The information stored in the data bucket may include a task identification, which is a unique identification of the information to be executed. Each client node 20 can identify whether certain information is information issued by the cloud management platform 10 to the client node through the task identifier, and the cloud management platform 10 can also acquire an execution result for the information uploaded by the designated client node from the data bucket based on the task identifier.

In some embodiments, if each client node 20 has a one-to-one data bucket on the infrastructure 11, the information stored in the data bucket may also include a task identifier, so that each client node 20 may identify, through the task identifier, whether a piece of information is currently issued by the cloud management platform 10 or is information issued in a history (the information client node 20 has already executed), and the cloud management platform 10 may also obtain, based on the task identifier, an execution result of the specified information from the data bucket.

As shown in fig. 5, taking the cloud management platform 10 for managing N client nodes 20, the cloud management platform 10 is used for providing backup software services for the N client nodes 20 as an example. The cloud management platform 10 may perform tasks such as scheduling a backup task, deleting expired backup data, and managing a state of a client node, where the client node 20 is configured to execute a backup instruction issued by the cloud management platform 10, and perform operations such as creating a backup and deleting a backup.

In some embodiments, each client node 20 may also have pre-installed backup proxy software that may be registered with the cloud management platform 10 such that each client node 20 may be brought into management by the cloud management platform 10. The cloud management platform 10 and the client node 20 may agree with a communication protocol in advance, so that the client node 20 may parse an instruction issued by the cloud management platform 10, and the cloud management platform 10 parses an instruction execution result uploaded by the client node 20.

Cloud management platform 10 may receive tenant-entered backup instructions for client node 20. The cloud management platform 10 may write the backup instruction to be executed by each client node 20 into a data bucket, the data bucket is provided with an access address facing the public network, and each client node 20 may actively obtain the backup instruction from the data bucket based on the access address, so as to implement that the cloud management platform 10 issues the backup instruction to each client node 20.

For example, each client node 20 may obtain the backup instruction issued by the cloud management platform 10 from the data bucket through a periodic access manner, where the periodic access may refer to accessing the data bucket every preset time, and the preset time may be set according to the actual requirement, which is not limited in the present application. After each client node 20 obtains the backup instruction, the backup instruction after the analysis can be analyzed, the analyzed backup instruction can be executed, and instruction execution information (such as execution progress and execution result of the instruction) can be uploaded to the data bucket, and the cloud management platform 10 can periodically query the instruction execution information reported by each client node 20 from the data bucket, so as to obtain the instruction execution condition of each client node 20, and provide the instruction execution condition for the tenant.

In some embodiments, if N client nodes 20 share a data bucket, the data bucket may include N information storage spaces corresponding to N client nodes 20, where each information storage space may be a sub-storage space in the data bucket or may be a directory in the data bucket, which is not limited in this disclosure. Each client node 20 may access the corresponding information storage space through the backup proxy software to obtain and execute instructions written by the cloud management platform 10, such as backup creation, backup deletion. The tenant may further configure a backup policy on the cloud management platform 10, so that the cloud management platform 10 may automatically issue a backup instruction to the client node 20 at a time point set by the backup policy. The backup policy may include the time, period, and retention rules for backup tasks to execute, backup data, and the like. The retention rules for backup data may include retention time or number of retention.

For example, when the cloud management platform 10 writes an instruction into the data bucket, the cloud management platform may write the instruction into the corresponding information storage space according to the client node to which the instruction belongs, where a first client node of the N client nodes 20 corresponds to the first information storage space, a second client of the N client nodes 20 corresponds to the second information storage space, and an nth client node of the N client nodes 20 corresponds to the nth information storage space. The first client node may actively access the first information storage space, read the instruction issued by the cloud management platform 10 from the first information storage space, and the nth client node may actively access the nth information storage space, read the instruction issued by the cloud management platform 10 from the nth information storage space. For example, the cloud management platform 10 writes a first instruction for controlling the first client node to perform backup creation to the first information storage space of the data bucket, and the first client node may obtain the first instruction by actively accessing the first information storage space, for example, the first client node may access the first information storage space once every preset time. After the first client node reads the first instruction, the first client node may parse the first instruction and execute the parsed first instruction. The first client node may further upload the execution result of the first instruction to the first information storage space, and after the cloud management platform 10 writes the first instruction into the first information storage space, the cloud management platform may also query at regular time whether the first information storage space stores the execution result of the first instruction uploaded by the first client node, so as to timely obtain the instruction execution state of the first client node and provide the result to the tenant.

In some embodiments, the data bucket may not be divided into information storage spaces, and the instructions written to the data bucket by the cloud management platform 10 may include task identifiers, for example, the nth client node may obtain an instruction including the task identifier associated with the nth client node by actively accessing the data bucket, and parse and execute the obtained instruction. The identification information is client identity information capable of uniquely identifying and executing the instruction, and the task identification can comprise task unique identity identification, task basic information and client identity information. For example, the client identity information may be a Device identity (Device ID), a Media Access Control (MAC) address, a Unique Device identification code (Unique DEVICE IDENTIFIER, UDID), etc.

Fig. 6 is a schematic diagram illustrating interaction among the cloud management platform 10, the client node 20, and the data bucket according to an embodiment of the present invention.

This embodiment is described taking as an example a software upgrade service provided by cloud management platform 10 to client node 20. The process of interaction between cloud management platform 10, client node 20, and the data bucket may include:

at 60, cloud management platform 10 receives tenant-entered information for client node 20.

In some embodiments, cloud management platform 10 may manage one or more client nodes 20, and the information for client nodes 20 may include a software upgrade package, or a software upgrade package and upgrade instructions. A tenant may refer to a user or vendor of client node 20.

The cloud management platform 10 writes 61 information for the client node 20 to the data bucket based on the first access credentials.

In some embodiments, a data bucket may be created by a tenant at cloud management platform 10, the data bucket being provided with a public network oriented access address. In order to improve the security of the information stored in the data bucket, the data bucket can conduct authority verification on the access request. For example, when cloud management platform 10 requests that information for client node 20 be written to a data bucket, the data bucket may determine that cloud management platform 10 has access to the data bucket based on the first access credentials carried by the write request of cloud management platform 10, the data bucket allowing cloud management platform 10 to write information for client node 20 to the data bucket.

In some embodiments, the data bucket may include N information storage spaces corresponding to N client nodes 20, and each client node 20 may obtain and execute information issued by the cloud management platform 10 by accessing the corresponding information storage space. Taking an example that the information includes a software upgrade package, that is, the cloud management platform 10 can write the software upgrade package issued to the first client node into the first information storage space, and the first client node can access the first information storage space to obtain the software upgrade package issued to the first client node by the cloud management platform 10; the cloud management platform 10 may write the software upgrade package issued to the nth client node into the nth information storage space, and the nth client node may access the nth information storage space to obtain the software upgrade package issued to the nth client node by the cloud management platform 10.

In some embodiments, if N client nodes 20 are the same client node, the tenant is a vendor of the client node, the data bucket does not need to divide the information storage space, and after the cloud management platform 10 writes the software upgrade package into the data bucket based on the first access credential, each client node 20 may obtain the software upgrade package from the data bucket based on the access address, so as to implement software upgrade.

The client node 20 obtains information for the client node 20 from the data bucket based on the second access credential and the access address 62.

In some embodiments, when client node 20 requests access to a data bucket based on an access address, the data bucket may determine that client node 20 has access rights to the data bucket based on a second access credential carried by the access request of client node 20, the data bucket allowing client node 20 to obtain information for client node 20 therefrom.

In some embodiments, the client node 20 may access the data bucket at intervals of a preset time to obtain the latest information issued by the cloud management platform 10, where the latest information may be information that has not been executed by the client node 20.

In some embodiments, for client node 20, client node 20 may determine whether the information is up-to-date information issued by cloud management platform 10 based on a write timestamp of the information or a task identification contained in the information. If it is determined that the information is the latest instruction issued by the cloud management platform 10, which indicates that the information client node 20 has not yet executed, the client node 20 may read the information. If it is determined that the information is not the latest information issued by the cloud management platform 10, it indicates that the information has been previously read by the client node 20, and the client node 20 does not perform reading of the information.

In some embodiments, information written to the data bucket by cloud management platform 10 may also be set to an unread state. When client node 20 reads this information, the information may transition from the unread state to the read state. I.e., client node 20 may determine whether the information is up-to-date information issued by cloud management platform 10 based on whether the information is read.

63, The client node 20 parses the acquired information and executes the parsed information.

In some embodiments, parsing the acquired information by client node 20 may refer to processing the acquired information to be loadable and executable by client node 20, such as parsing a software upgrade package. If the cloud management platform 10 encrypts the information written into the data bucket, the analysis of the acquired information by the client node 20 may further include decryption of the information.

At 64, client node 20 uploads the results of the execution of the information to the data bucket.

For example, the execution result of the client node 20 execution information is software upgrade success information or software upgrade failure information, and the client node 20 may upload the software upgrade success information or the software upgrade failure information to the data bucket.

In some embodiments, the client node 20 may also periodically upload execution information (information about the progress of information execution, the result of information execution, etc.) of the information to the data bucket until the execution of the information is completed.

In some embodiments, when the client node 20 uploads the execution result of the information to the data bucket, the data bucket may further determine that the client node 20 has access rights based on the second access credential carried by the upload request of the client node 20, that is, allow the client node 20 to upload the execution result of the information to the data bucket.

65, The cloud management platform 10 accesses the data bucket, and obtains the execution result of the information from the data bucket.

In some embodiments, after writing information to the data bucket, cloud management platform 10 may access the data bucket once every preset time to obtain the execution result of the information uploaded by client node 20 from the data bucket. After acquiring the execution result of the information, the cloud management platform 10 may provide the execution result of the information to the tenant, for example, display the execution result of the information through a page.

In some embodiments, when the cloud management platform 10 accesses the data bucket, the data bucket may further determine that the cloud management platform 10 has access authority of the data bucket based on the first access credential carried by the access request of the cloud management platform 1, that is, allow the cloud management platform 10 to obtain an execution result of the information uploaded by the client node 20 from the data bucket.
