Given the increasingly important role AI is playing in our society, I want to create a series of posts about the backend infrastructures that enable these services to process immense amounts of data per second. A key component in making these massive clusters work is storage, without which HPC clusters would not be able to access and process data. One of the storage solutions used to deliver huge throughput performance is Lustre. Let’s explore what it is, how it works,…

Post category:Cloud Tutorial

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

Post published:23 April 2024
Post category:Cloud Tutorial

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…
