        node app.js
        
        <h1>Compile and run a Java program</h1>
        
        javac Main.java
        java Main
        

        5. CI/CD:

        • GitHub Actions, Jenkins, TeamCity, Gitlab, CircleCI: CI/CD tools automating the development, testing, and deployment process.
        • Commands:

          </li>
          </ul>
          
          <h1>Trigger a Jenkins job</h1>
          
          curl -X POST http://jenkins-url/job/jobname/build
          
          <h1>Run a GitHub Actions workflow</h1>
          
          git push origin main
          

          6. Security:

          • JWT, OAuth 2.0, API Authz., TLS: Essential security protocols and encryption methods ensuring data integrity and access control.
          • Commands:

            </li>
            </ul>
            
            <h1>Generate a self-signed SSL certificate</h1>
            
            openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365
            

            7. Cloud Providers:

            • AWS, Azure, GCP, Linode, Digital Ocean: Cloud providers offering infrastructure and services for hosting microservices.
            • Commands:

              </li>
