- In this blog, we show how we created a Datastax Cassandra cluster on Oracle Cloud Infrastructure (OCI) using Terraform and benchmark Oracle Cloud baremetal machines running Cassandra stress. 1. Steps to Create the Cluster Go here to download the Terraform project Follow the guide to setup your environment Edit the file env-vars and fill in all the relevant info for your OCI account edit variables.tf and select the shape of your OCI instance, we used DenseIO1.
- The focus of this article would be cloud specific steps rather than repeating already well known steps in the net.Its purpose is only to give you an idea for an use case and should not be used in a production environment. The high level setup: Source: Two nodes (VirtualBox) Oracle Linux 7. Oracle Grid Infrastructure 12.2 . Oracle RAC 12.2, storage ASM. Target (to be created) in Oracle cloud:
Oracle introduced two type of cloud services. OCI (Oracle Cloud Infrastructure) Formerly called Bare metal cloud, and OCI Classic.
In this blog I will cover Oracle Cloud infrastructure. OCI Provides two type of shapes: Virtual machine and Baremetal, We can select virtual machine or bare metal while creating instance and selecting shape in OCI. Bare metal prefix with BM, Virtual Machine prefix with VM. Oracle use KVM based virtualization for VMs.
BM instances in Oracle Cloud Infrastructure run without Hypervisor and provides Good Performance consistently. They supports High IOPS and are good for I/O Intensive application, noSQL, Big Data and Databases. It will use physical machine resource within tenant.
In this example I will create Virtual Machine, but process of creating Bare metal instance is basically same.
