Post published:29 October 2024
Post category:Cloud Technology

In today’s high-performance computing (HPC) landscape, storage solutions that offer speed, scalability, and reliability are essential. Lustre, an open-source parallel file system, is a popular choice for HPC environments due to its capacity to handle large datasets and intensive workloads. When deploying Lustre on Oracle Cloud Infrastructure (OCI), achieving an optimized design that balances performance with cost-efficiency requires careful planning. Let's explore key Lustre infrastructure design patterns tailored for OCI, focusing on strategies to meet diverse storage needs and performance…

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

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…
