What are the SpringCloud pits encountered in the Java interview? I believe many inexperienced people don't know what to do about it. Therefore, this article summarizes the causes and solutions of the problems. Through this article, I hope you can solve this problem.

one。 What problems does Spring Cloud solve?

Complexity associated with distributed systems-including network problems, delay overhead, bandwidth issues, security issues.

Ability to handle service discovery-Service discovery allows processes and services in the cluster to find and communicate with each other.

Solve redundancy problems-redundancy problems often occur in distributed systems.

Load balancing-improved across multiple computing resources (e.g., computer clusters, network links, central

The workload distribution of the management unit.

Reduce performance problems-reduce performance problems caused by various operational overhead.

two。 What is two-factor authentication?

Two-factor authentication enables second-level authentication for the account login process.

three。 How to eliminate indeterminism in testing?

Non-deterministic testing (NDT) is basically unreliable testing. So, sometimes they may pass, and obviously sometimes they may fail. When they fail, they rerun through.

Some ways to remove indeterminacy from a test are as follows:

1. Isolation

2. Async

3. Remote service

4. Isolation

four。 Advantages of microservices

Independent development-all microservices can be easily developed according to their respective functions

Standalone deployment-based on their services, they can be deployed separately in any application

Fault isolation-the system can continue to run even if one of the application's services does not work

Hybrid technology stack-different languages and technologies can be used to build different applications

Service

Granularity scaling-individual components can be scaled as needed without scaling all components together

five。 How does the micro-service architecture work?

Look at the picture and see the effect.

six。

Client-different users from different devices send requests.

Identity provider-authenticates the user or customer and issues security tokens.

API Gateway-handles client requests.

Static content-holds all the contents of the system.

Management-balance services and identify faults on the node.

Service Discovery-A guide for finding communication paths between microservices.

Content delivery network-the distributed network of proxy servers and their data centers.

Remote Service-enables remote access information that resides on the network of IT devices.

seven。 What are the advantages and disadvantages of the microservice architecture?
