It should be noted that the above storage form is only an example, and other forms of storage may be adopted in practical applications.

The invention is described in its entirety with reference to the following specific examples:

the specific embodiment mainly solves the problem that when the current cloud computing platform is subjected to multi-site disaster recovery, connection scattered code redundancy is created, and tasks fail due to connection failure or overtime. After the connection is overtime and the authentication information is modified by the user, the connection can be automatically authenticated and updated, the externally provided connection is ensured to be available, the user does not feel the connection, the connection is created and is intensively processed, the creation of the remote connection is reduced, the resources are saved, and the later maintenance is convenient. The connection center stores the remote site id (identification) and the remote connection (i.e., object information) in a cache in the form of key-value, periodically refreshes the connection, and invokes a method to re-authenticate if the connection fails or times out. In this way, the developer does not need to care about the connection state, namely, the user can use the device, and the task in execution cannot fail due to the fact that the authentication information is modified in the use process. The connection establishment is put in the connection center, the connection is convenient to uniformly manage, the later maintenance is convenient, the workload of developers is reduced, and the working efficiency is improved.

In this embodiment, the connection center may include four parts, namely, a generator, a memory, an updater, and a cleaner, where the functions of the four parts are as follows:

when the cloud computing platform adds the remote site, the generator creates a remote site connection according to the remote site ip, the user name, the password and the port. The memory stores the connection in a form of key-value, the key value is a remote site id (corresponding to the identifier), the value is a remote site connection object (corresponding to the object information), when the remote site is newly added, whether the authentication information is correct or not is checked, the connection center stores the correct authentication information in a database, the generator reads the authentication information from the database to create the remote connection, and stores the connection in the memory in a form of key-value, the key value is the remote site id, and the value is the connection object. In addition, a plurality of remote sites may be added, in which case a connection needs to be created between the connection center and each of the remote sites.

After editing the remote site user name or password, the connection center will check whether the authentication information is correct, and then will update the correct authentication information into the database. The updater will read the authentication information from the database to recreate the connection, i.e. the updater will recreate the remote connection based on the authentication information and update the new connection into the value in memory with the key value of the remote site id (all valid connections currently will be recorded in the memory of the connection center).

When the remote site is deleted, the cleaner deletes the connection whose key value in memory is the remote site id.

The architecture of the connection center and the connection relationship with the site manager (may be simply referred to as site management) may refer to fig. 3, where authentication information of all remote sites is stored in the site management, and the connection center may be acquired from the site management when authentication information of part of the remote sites needs to be acquired.

Fig. 4 is a flowchart of a method for acquiring a connection from a connection center according to an embodiment of the present invention, which mainly includes the following steps:

s401, a local site initiates a connection request for inquiring a remote site;

s402, the connection center searches the storage information with the key as the remote site id;

s403, the connection center judges whether the storage information with the key as the remote site id exists in the storage, and if yes, the step S404 is shifted to, otherwise, the step S415 is shifted to;

s404, checking connectivity with the remote site under the condition that the query key is the stored information of the remote site id;

s405, judging whether the connection is performed or not based on the verification result;

s406, returning to the connection object in the case of determining the connection;

s407, the local site takes the connection, and further, the subsequent calling operation is executed based on the taken connection;

S408, further judging whether the connection between the connection center and the remote site is invalid or not under the condition that the communication is not confirmed, turning to a step S409 under the condition that the connection is confirmed to be invalid, and turning to a step S411 under the condition that the connection is confirmed to be invalid;

s409, re-authenticating the remote site;

s410, judging whether the re-authentication is successful or not, and turning to step S406 if the re-authentication is successful, and turning to step S411 if the re-authentication is determined to be failed;

s411, calling a cleaner to delete the connection between the connection center and the remote site;

s412, performing exception capture processing after the re-authentication fails;

s413, printing log information;

s414, feeding back a response that the connection is not taken to the local site;

s415, reading authentication information of the remote site by using a generator;

s416, creating connection between the connection center and the remote site based on the read authentication information;

s417, save the created connection.

Based on the steps, in the development process and the subsequent actual use process, under the multi-site disaster recovery scene, when the tasks such as the execution of the protection group operation, the virtual machine operation, the backup scheduling and the like need to be connected, only the remote site id is needed to be used for searching the memory. That is, when using connection, a value whose key value is the remote site id needs to be queried from the memory, that is, the corresponding remote connection object. If the key value is not in the memory and is the remote site id, the memory creates a remote connection through the generator, stores the remote connection in the memory, and returns a connection object. In addition, when the connection is obtained from the memory, the memory will first check the validity of the connection (for example, call a certain interface of the remote site, indicate that the connection is valid if the remote site can return a correct message), and if the connection fails due to a login timeout or a user of the remote site, a password change (a situation that a temporary failure exists because a period of time is required after the password change) or the like, the memory will be automatically reconnected (the connection can be normally used after the reconnection is successful, and a new connection object will not be generated), and for the situation that the connection cannot be made due to a network cause (that is, the connection fails rather than the connection fails), the memory automatically captures and processes an exception (the exception code of the connection timeout or the failure is fixedly known), and prints detailed log information, and deletes the remote site id data through the cleaner; if the connection fails and is invalid, re-authenticating, returning the connection object after the re-authentication is successful, performing exception capturing processing after the re-authentication is failed, printing log information, and deleting the remote site id data through a cleaner; if the connection is successful, the connection object is directly returned.

In the task of operating the protection group, the virtual machine and the backup scheduling, remote connection needs to be called, data is synchronized at the remote end, and a developer or other users only need to take the connection object from the memory through the remote site id for direct use. The developer or other users do not need to create the connection by themselves, pay attention to the validity of the connection, deal with the abnormal situation of the connection, worry about task failure caused by overtime or disconnection of the connection, and deal with the abnormal connection in the memory. The connection receiving and returning connection center management is established, the code redundancy is reduced, connection is not required to be established every time, the login task of a remote site is reduced, the code concentration and the coupling are low, and the later maintenance is convenient. The connection is convenient to manage uniformly, the workload of developers or other users is reduced, and the working efficiency is improved.

It should be noted that when the cloud computing platform restarts the platform service, the cache will be emptied, and at this time, when the local site queries the remote site from the connection center, the key value corresponding to the remote site id will not be found, in this case, the remote connection will be created first, saved in the cache, and then the connection will be returned. In addition, the remote site may fail after restarting the platform services.
