Example: Team members can work together on code easily.
Docker & Docker Swarm
What: Create containers to run applications.
Example: Ensures your app works the same on any computer.
Jenkins (CI/CD Pipelines)
What: Automate building, testing, and deploying code.
Example: Jenkins automatically tests your app and puts it online.
Kubernetes & Helm
What: Manage and scale containerized applications.
Example: Keeps your app running smoothly even if traffic increases.
Cloud Services (AWS, GCP, Azure)
What: Online services to run and store applications.

Infrastructure as Code (IaC)
What: Manage servers and infrastructure with code.
Tools: Use Terraform to set up servers, Ansible for configuration.
Example: Set up all servers with a script.
Monitoring with Grafana
What: Keep track of your app’s health.
Example: Grafana shows how your app is performing.
Real-Time Example
Imagine you are working on a shopping website:
Using Git: Team members save their code in a shared place.
Using Jenkins: Automatically test and put new features online.
Using Docker: App runs the same way on any computer.
Using Kubernetes: App scales up if many users visit the site.
Using AWS: Host the website online.
Using Grafana: Monitor how well the website is running.
