Today I learned about Kubernetes (K8s) architecture , and honestly, it’s both beautiful and sophisticated.
Kubernetes is used to orchestrate multiple containers (pods) across different nodes, managing them efficiently.
K8s has two core parts:
1. Control Plane
2. Worker Nodes
The control plane has five main components: the API server, etcd, scheduler, and controller manager. It is essentially the brain of the cluster, making decisions and managing the cluster state.
Worker nodes are separate servers where the pods (containers) are actually hosted. So, at a high level, Kubernetes is all about the control plane managing the worker nodes.
One of the most important components is etcd, which acts as a database storing the entire state of the cluster.

The Raft consensus algorithm requires an even number of etcd servers to ensure high availability.

After doing a lot of research, I found this is one of the best roadmaps to learn DevOps especially if you’re planning to work with microservices.
Assuming you already have a base knowledge of Linux and basic networking:
1️⃣ Start with Docker – Learn Docker architecture, essential commands, Docker Compose, and how to build and push your images.
2️⃣ Move to Kubernetes – Understand Kubernetes architecture, pods, clusters, nodes, and kubectl/API basics.
3️⃣ Pick one cloud provider – In this case, AWS. Focus on core services like EC2, ECS, EKS, VPC, IAM, S3, and Fargate.
4️⃣ Learn Infrastructure as Code (IaC) – Study Terraform fundamentals: commands, project structure, variables, and modules.
5️⃣ Monitoring & Logging – Learn Prometheus and Grafana for observability.

AWS Services Series — AWS EC2
AWS EC2 is basically just a server in the cloud but you configure everything.
You choose the image (OS), but you install and configure things like Nginx, security groups (firewall), networking, storage, etc.
👉 Total flexibility.
💰 Pricing:
EC2 charges you per uptime from the moment the instance starts until you stop it.
Typical pricing (varies by region):
* t3.medium: ~$0.0416/hour
* Also you will be paying for storage EBS(~$0.08–$0.125 per GB/month) also Public IPV4 address
⚠️ If your instance is running idle, you STILL pay.

If you're just returning JSON, you're just exposing a DB.

Might sound a bit weird 😁, but I’m building Current.fm, a platform where you can stream your Spotify music listening to the world. It aggregates everyone listening to the same song as you, shows who they are, and displays the top 10 songs being streamed right now, including breakdowns by country.
You can just connect your Spotify and just leave it and it will stream as long as you don't pause the song.
What do you think?
Watch the demo.
