✨ What is Git?
✔️ Git is a version control system.
➡️ Storing Artifacts – Keeps all code and related files in a central place.
➡️ Traceability – Git keeps a history of every change you make.
✔️ You can see who added a new feature last week and why.
➡️ Versions & Rollback – Roll back to an earlier version anytime.
✔️ If today’s code breaks, you can restore yesterday’s working version.
➡️ Collaboration – Teams can work together without overwriting each other’s work.
✔️ Two or more developers can edit different files at the same time without conflict.
➡️ Branching & Merging – Work on new ideas safely in branches, merge later.
✔️ A developer tests a new feature in a branch without affecting main code.

✨ What is GitOps?
✔️ GitOps takes the idea of Git beyond just code.
➡️ Single Source of Truth – Store infrastructure and deployment configs in Git.
✔️ Your Kubernetes config lives in a Git repo just like your app code.
➡️ Automation – Every Git commit can trigger automatic deployments.
✔️ Merging a pull request can immediately update your production app.
➡️ Auditable Changes – Every change is tracked and reviewed via pull requests.
✔️ You always know who changed a production setting and when.
➡️ Faster Recovery – Roll back infrastructure by reverting commits.
✔️ Undoing a faulty server config is as easy as reverting a code change.
➡️ Security & Policy – Access to infrastructure is controlled via Git workflows.
✔️ Only approved pull requests can change production systems.

✨ What is Docker?
✔️ Docker helps developers package applications and everything they need (libraries, dependencies, configs) into a single unit called a container.
➡️ Consistency – Package your app with all dependencies in one container.
✔️ Your app runs the same on a laptop, test server, or cloud.
➡️ Lightweight – Containers are faster and smaller than virtual machines.
✔️ Starting a container takes seconds, unlike booting a full OS.
➡️ Portability – Move apps easily across environments.
✔️ A container built on Windows can run on Linux in the cloud.
➡️ Isolation – Each container runs separately from others.
✔️ Two apps can use different versions of the same library without conflict.
➡️ Microservices Friendly – Perfect for breaking apps into independent services.
✔️ Payment, search, and login can each run as separate containers.

✨ What is Kubernetes?
✔️ When you have just one Docker container, life is easy. But what if you need hundreds running across many servers? That’s where Kubernetes comes in.
➡️ Scaling – Run and manage hundreds of containers across servers.
✔️ If your app gets 1M users, Kubernetes scales containers automatically.
➡️ Self-Healing – Restarts containers if they crash.
✔️ If a server fails, Kubernetes moves your app to a healthy one.
➡️ Smart Updates – Rolls out new versions without downtime.
✔️ Users don’t even notice when your app gets upgraded.
➡️ Load Balancing – Distributes traffic across containers.
✔️ User requests are spread evenly, so no server is overloaded.
➡️ Resource Optimization – Efficiently uses CPU, memory, and storage.
✔️ Containers needing more memory are scheduled on bigger servers.
➡️ Cloud-Native Standard – Runs on any cloud (AWS, GCP, Azure) or on-prem.
✔️ The same Kubernetes setup works on laptops, datacenters, or the cloud.
