What is the concept of redis SSO

This article mainly explains "what is the concept of redis SSO". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what is the concept of redis SSO"?

Specific content

When using the SSO concept, it must indicate that your development environment is a multi-cluster host.

2.1. Problems faced by the cluster

The most important features of using cluster design are:

Increased access speed

Have a stronger ability to handle

Data is more secure

Disaster tolerance is also very high.

Because even if there is a problem with one host, other hosts can also be used directly. In addition to the architecture cluster of the system, many developers will also consider using more subsystems to write projects in order to take into account the comprehensive performance. The use of subsystems can effectively achieve the encapsulation of data operations. Externally, the concept of RPC can be used to achieve more convenient method calls.

Well, now we can actually find that in a huge system design, the login problem of the user will become the biggest difficulty, because it is impossible to say that the user logs in when he logs in to the WEB, and then when the user performs an operation, you also log in once when the operation calls the RPC for business execution, and the login of such an operation is too terrible.

2.2, introduction to SSO

SSO itself is just a noun, because the specific implementation technology is not called SSO.

In the current SSO design process, the Redis cache database will be responsible for storing the user's role and permission information, so that repeated query processing of role and permission data can be avoided. In the whole SSO processing, in order to ensure the security of single sign-on, we also need to use https access, as well as the issuance of certificates, in order to normally use SSO for single sign-on.

At this point, I believe you have a deeper understanding of "what is the concept of redis SSO". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
