Accessing OCI Compute Instances Using VNC Console (Instance Console Connection)

Image
  Overview In Oracle Cloud Infrastructure (OCI), administrators occasionally face scenarios where SSH access to a compute instance is unavailable —for example, due to network misconfiguration, firewall issues, or OS-level boot problems. To handle such situations, OCI provides Instance Console Connection , which enables VNC-based graphical console access and serial console access to compute instances. In this post, I demonstrate how to access an OCI Compute instance using the VNC console , explain when to use it, and highlight best practices for secure and effective troubleshooting. ⚠️ This demonstration is performed in a personal OCI tenancy using test instances. No customer environments or confidential information are exposed.

Building a Lightweight Point-to-Site VPN on OCI Using PiVPN (WireGuard) on OCI

Image
 Overview Remote administrative access to cloud environments is a common requirement. While IPSec VPN and Client VPN services are robust, there are scenarios where teams need a lightweight, quick-to-deploy, and cost-effective Point-to-Site (P2S) VPN solution . Currently in OCI there are no native client access VPN services available. In this post, I demonstrate how to build a WireGuard-based P2S VPN on Oracle Cloud Infrastructure (OCI) using PiVPN , an automation-friendly installer that simplifies WireGuard deployment.  ⚠️ This demonstration is implemented in a personal OCI tenancy using test resources. No customer environments or confidential information are used.

Automating OCI Volume Group Backup Cleanup Using OCI CLI (Cost Optimization)

Overview In Oracle Cloud Infrastructure (OCI), Block Volume and Volume Group backups are critical for data protection. However, retaining old backups indefinitely leads to unnecessary storage costs , especially in production and DR environments. In this post, I demonstrate how to automate the cleanup of OCI Volume Group backups older than 7 days using OCI CLI , with: Safe filtering logic Multi-compartment support Logging and audit-friendly output Optional dry-run mode ⚠️ This demonstration is executed in a personal OCI tenancy using test resources. The same automation pattern is applicable to enterprise environments without exposing customer data.
