How to setup a linux Virtual IP Failover (IP Floating) on Oracle OCI managed by pacemaker

Introduction In many environments, it is still essential to use infrastructures with an active/passive Linux cluster, which require the use of IP floating. In cloud infrastructures, the secondary IP address must be managed not only by the operating system but also by the cloud infrastructure. In this tutorial, we will see how the IP floating of a Linux cluster can be managed as an integrated resource by Pacemaker, in a simple manner and without custom code, as seen in several…

Establish a VPN with Oracle OCI with a dynamic public IP ADDRESS on CPE

Oracle Cloud Infrastructure (OCI) does not support the use of Domain Name System (DNS) for configuring the Customer Premises Equipment (CPE) as the VPN tunnel endpoint. This tutorial aims to enable small businesses that do not have access to a static public IP address to use the IPSec service even with a dynamic address. The strategy involves deploying a script capable of automatically generating a new OCI tunnel whenever the public IP of the Customer Premises Equipment (CPE) changes. In…

Deploy an HA SAMBA cluster with Windows Active Directory integration on OCI

In this post, we discuss how to configure an high availability with automatic failover of SAMBA on UBUNTU instances into Oracle OCI. This solution is a robust and reliable file server infrastructure, leveraging the power of a clustered SMB setup and completly license free. The cost is related only to the consumption (oCPU and Block Volume size). The benefits of implementing a clustered SMB file server service into your organization are multiple: Reliability: The clustered configuration ensures high availability, minimizing…
