Building a Free Cloud Infrastructure - From Free High-Spec Servers to Deploying Your Own App (feat. Oracle, k8s) Course

Building a Free Cloud Infrastructure - From Free High-Spec Servers to Deploying Your Own App (feat. Oracle, k8s)

I want to launch a side project as a real service and study Kubernetes, but managed services from AWS/GCP (EKS, GKE, etc.) are too expensive. On the other hand, running it only on a local computer makes it difficult to experience network configurations or actual deployment environments. We will utilize the "Always Free" tier of Oracle Cloud (OCI), which offers the most powerful free benefits among existing public clouds. By installing the lightweight yet powerful k3s, we will build a Linux server and Kubernetes environment capable of hosting actual services from scratch—all at zero cost. After taking this course, you will gain a general understanding of cloud networking and possess your own Kubernetes cluster infrastructure where you can deploy and operate your applications for free.

I am writing to inform you that there has been news regarding changes to the Oracle free resource limits.

Hello.

It is said that there are changes to the Oracle free resource limits.

Existing 4core cpu + 24gb ram

Changed to 2core cpu + 12gb ram

For those who have already created them, master 1core cpu, 6g ram / worker 1core cpu, 6g ram

It seems you need to reduce your usage to avoid being charged. (It is expected that if you continue to use the full capacity, a charge of about $26 will be incurred.)

It appears that the content of the official Oracle documentation has also been updated.

I will update and upload the lecture PDF files and lecture notes.
