Description
Technical Field
The invention relates to the technical field of distributed coordination services, in particular to a method, a device and a system for processing distributed coordination services.
Background
Some cloud service providers provide compatible distributed coordination services in a manner that the distributed coordination services fully host operations and maintenance. In this way, specifically, the user directly or indirectly purchases the virtual machine resource, and then the service provider deploys and operates the distributed coordination service on the virtual machine of the user. The distributed coordination service deployed in the mode is located in the cluster environment of the user, the isolated network is used for safety protection, the problem of network crossing limitation does not exist, and the distributed coordination service is relatively simple. But the problem exists in that the distributed coordination service does not generate more remarkable value than the operation and maintenance of the user, and the problem of the ubiquitous cost and horizontal expansibility in the process of using the distributed coordination service by the user still exists. Fundamentally, the distributed coordination service cannot be provided for the user to use in a true service mode, and the operation mode of 'selling software' is still essential.
An emerging open source consistency coordination project represented by ETCD and Consul adopts an HTTP mode to provide better safety control, and the HTTP mode is more favorable for penetrating a complex network environment. However, because their protocols use a session implementation mechanism that is not connection-related, they cannot be compatible with the session protocol of connection coupling of the distributed coordination service, and thus there is a huge migration cost for a large number of users using the distributed coordination service.
The client protocol of the distributed coordination service adopts simple ACL security control, and the security is poor. However, in order to maintain complete compatibility with the open-source distributed coordination service protocol, it is difficult to improve security from the client protocol in the prior art. In addition, a client protocol of the distributed coordination service adopts a session design of connection coupling, and the client establishes direct TCP connection communication with the consistency storage back end. In a user-specific cluster environment (such as a proprietary cloud, VPC, and the like), the protocol has difficulty penetrating a complex network structure.
In view of the above problems, no effective solution has been proposed.

In the foregoing operating environment, fig. 3 is a flowchart of a processing method of a distributed coordination service according to an embodiment of the present invention, and as shown in fig. 3, the processing method of the distributed coordination service is applied to a network including a client, an API gateway disposed in a user network environment, and a distributed coordination service, and the method may include the following steps:
step S301, obtaining a session sent by at least one client with established connection, and obtaining a session set, wherein the session and the connection have a corresponding relationship.
Step S303, the corresponding relation between the session and the connection in the session set is removed through the API gateway to obtain the decoupled session, wherein the API gateway is a gateway compatible with the session in the coupled distributed coordination service protocol.
The API gateway may route all user requests of all clients passing through it to the appropriate distributed coordination server after processing. The distributed coordination server side and the API gateway are established with a mutual trust mechanism, so that normal routing of the decoupled user request can be ensured.
In step S303, the API gateway releases the correspondence between the sessions and the connections in the session set, and obtaining the decoupled session includes: removing the corresponding relation between each session in the session set and the connection through the API gateway to obtain a request carrying a session identifier; and creating the decoupled session based on the request carrying the session identifier.
As shown in fig. 4, each session bound by the connection is sent to the API gateway through a plurality of clients, and each session includes at least one request, for example, client 1 sends session a to the API gateway through connection 1, where session a includes two requests, R6 and R2. Client 2 sends session B, which includes two requests, R4 and R1, to the API gateway over connection 2. The client 3 sends a session C to the API gateway over connection 3, where the session C includes two requests, R5 and R3 respectively. After receiving a plurality of sessions, the API gateway decouples each session (cancels the correspondence between each session and the connection) to obtain a request carrying a session identifier, for example, after decoupling session a, request R6 carries session identifier a, and request R2 carries session identifier a. After session B is decoupled, request R4 carries session identifier B, request R1 carries session identifier B, after session C is decoupled, request R5 carries session identifier C, and request R3 carries session identifier C. And establishing the decoupled session based on the request carrying the session identifier, and then sending the decoupled session to the distributed coordination server through the same connection by the API gateway.
Optionally, in the processing method for distributed coordination service provided in the first embodiment of the present invention, each session includes at least one request, and the removing, by the API gateway, the corresponding relationship between each session and connection in the session set to obtain the request carrying the session identifier includes: the API gateway acquires a session identifier of each session; and respectively adding the session identifier corresponding to the session to at least one request to obtain the request carrying the session identifier.
For example, as shown in fig. 4, the session a includes two requests, which are R6 and R2, respectively, the API gateway obtains the session identifier a of the session a, and adds the session identifier a corresponding to the session a to R6 and R2, respectively, to obtain a request carrying the session identifier (the request R6 carries the session identifier a, and the request R2 carries the session identifier a).
Optionally, in the processing method of distributed coordination service provided in the first embodiment of the present invention, the number of requests carrying session identifiers is multiple, and the sending, by the API gateway, the decoupled session to the distributed coordination service end by using a shared connection includes: establishing a shared connection between the API gateway and the distributed coordination server; and sending the decoupled session created based on the requests carrying the session identification to a distributed coordination server through a shared connection.
In the scheme, the shared connection between the API gateway and the distributed coordination server is established, each request in the shared connection carries a session identifier, and the decoupled session created by sending a plurality of requests carrying session identifiers by using one shared connection is beneficial to penetrating a complex network environment, so that better security control is realized.
Step S305, the API gateway sends the decoupled session to a distributed coordination server by adopting shared connection, wherein the distributed coordination server coordinates execution logic of different components in the distributed computing environment based on the decoupled session.
The distributed coordination server is mainly used for realizing distributed coordination service, and can be used for coordinating and synchronizing execution logics of different components in a distributed computing environment, for example, a distributed lock application scenario, a distributed queue application scenario, a service registration discovery application scenario, and the like.
In the embodiment, after a session sent by at least one connected client is obtained and a session set is obtained, the API gateway is used for removing the corresponding relation between the session and the connection in the session set to obtain a decoupled session, and the API gateway sends the decoupled session to the distributed coordination server by using a shared connection, so that the distributed coordination server can coordinate the execution logic of different components in the distributed computing environment based on the decoupled session, thereby achieving the purpose that the API gateway, which establishes a trust mechanism with both the client and the distributed coordination server, decouples the session and the connection and then sends the decoupled session to the distributed coordination server, and the API gateway sends the decoupled session to the distributed coordination server through the same connection (corresponding to the shared connection), thereby improving the security of the session transmitted in the user network environment from the client protocol, and furthermore, the technical problem that in order to keep complete compatibility of the open-source distributed coordination service protocol, the security is difficult to improve from the client protocol in the prior art is solved.
The invention is described below with respect to an alternative distributed coordination service processing method.
Fig. 5 is a flowchart of an optional processing method for a distributed coordination service according to an embodiment of the present invention, and as shown in fig. 5, before an API gateway sends a decoupled session to a distributed coordination service end by using a shared connection, the processing method for the distributed coordination service may further include:
step S501, the API gateway sends an identity information verification request to the distributed coordination server.
That is, before the API gateway sends the decoupled session to the distributed coordination server using the shared connection, a trust mechanism between the API gateway and the distributed coordination server needs to be established. For example, the API gateway may verify the identity information by sending an identity information verification request, such as an identifier of the API gateway, to the distributed coordination server.
Step S503, receiving the verification result fed back by the distributed coordination server based on the identity information verification request.
That is, after receiving the identity information verification request sent by the API gateway, the distributed coordination server verifies the identity information verification request, and feeds back a verification result to the API gateway.
And step S505, if the verification result is that the verification is passed, establishing the connection between the API gateway and the distributed coordination server.
In this embodiment of the present invention, before starting the formal service client, the API gateway corresponding to the distributed coordination server needs to establish a connection with the distributed coordination server, where the connection establishment process includes a completely customized verification process that better meets the cloud service security prompt requirement, for example, an AccessKeyId or AccessSecret key signature verification based on a cloud account, or other flexible and diverse security verification mechanisms, thereby improving the security of the transmission session.
