How is the automated deployment process of new software versions implemented?.

The automated process of deploying new software versions is usually implemented using CI/CD (Continuous Integration / Continuous Deployment) pipelines. Main steps:

1. Build and test — code is automatically built and unit tests are run.
2. Create artifacts — packages or images (e.g., Docker) are formed.
3. Deploy — the new version is automatically deployed to a test or production environment.

Tools such as Jenkins, GitLab CI, GitHub Actions, ArgoCD, Spinnaker are used for this. Scripts and configurations describe the sequence of actions, which eliminates manual errors and speeds up the release of new versions.

Example of a simple Jenkinsfile:

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                sh 'mvn clean package'
            }
        }
        stage('Test') {
            steps {
                sh 'mvn test'
            }
        }
        stage('Deploy') {
            steps {
                sh './deploy.sh'
            }
        }
    }
}
