How to resize the boot drive in OCI

If you going out of space you have to to increase size of the partition. In this guide I explain step by step how to increase boot partition size on running server.

How to Deploy Compute Servers in OCI: A Practical Deep-Dive Guide

In this tutorial, I’ll walk you through the correct, repeatable, and secure way to deploy compute instances in Oracle Cloud Infrastructure. Whether you're building your first Always Free VM or deploying production Linux servers, getting the fundamentals right saves you hours of troubleshooting later. Compute instances are the backbone of your workloads—web servers, application services, database clients, automation nodes, and more. A wrong setup creates security gaps, performance issues, or unnecessary exposure to the public internet.

Building a Secure VCN in OCI: A Complete Guide for Small Businesses

In this guide, I’ll take you through a deep technical walkthrough of building a Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure. If you’re a small business owner, developer, or network engineer, this is the foundation of everything you will ever deploy in OCI. A poorly designed VCN creates ongoing problems—slow services, blocked traffic, security exposures, and troubleshooting nightmares.
