.NET 4.0 is used to create a variety of applications and it provides application developers with rich features including: object-oriented programming, flexibility, powerful architecture, cloud computing integration, performance optimization, extensive libraries, security, Scalability, data access, and mobile development support.

In a serverless architecture, Java functions can be integrated with the database to access and manipulate data in the database. Key steps include: creating Java functions, configuring environment variables, deploying functions, and testing functions. By following these steps, developers can build complex applications that seamlessly access data stored in databases.

This article introduces how to configure MongoDB on Debian system to achieve automatic expansion. The main steps include setting up the MongoDB replica set and disk space monitoring. 1. MongoDB installation First, make sure that MongoDB is installed on the Debian system. Install using the following command: sudoaptupdatesudoaptinstall-ymongodb-org 2. Configuring MongoDB replica set MongoDB replica set ensures high availability and data redundancy, which is the basis for achieving automatic capacity expansion. Start MongoDB service: sudosystemctlstartmongodsudosys

This article describes how to build a highly available MongoDB database on a Debian system. We will explore multiple ways to ensure data security and services continue to operate. Key strategy: ReplicaSet: ReplicaSet: Use replicasets to achieve data redundancy and automatic failover. When a master node fails, the replica set will automatically elect a new master node to ensure the continuous availability of the service. Data backup and recovery: Regularly use the mongodump command to backup the database and formulate effective recovery strategies to deal with the risk of data loss. Monitoring and Alarms: Deploy monitoring tools (such as Prometheus, Grafana) to monitor the running status of MongoDB in real time, and
