# Oracle Cloud

Languages
=> /posts/oracle-cloud/ 🇬🇧English



After my student subscription to Microsoft Azure ended, I looked into other options. Then I heard of the generous offer of Oracle Cloud: 4 cores and 24 Gigs of RAM on ARM CPUs.

> On AWS, that would cost you about 100$/month ! (2×`r6g.large` + 2×`t4g.medium`)

And that's free forever !

The – catch – is that these instances are Ampere A1 ARM CPUs, so a different architecture than your typical desk PC: software compiled for `x86` won't work…

Luckily, most main open-source software already provides ARM packages. And running on a different architecture forces you to think about people running other archs: Raspberry Pis, Pinebooks, M1 Macs ...

One interesting thing about Oracle compared to other is that they offer a wide range of virtualisation technologies to cater specific entreprise needs. For instance, you can select between BIOS or UEFI for the firmware, VFIO/Paravirtualize/IDE/ISCI... for your disk, and even stuff like IOMMU !

### Resources overview

The names of stuff is always a bit different on each cloud provider, so I'll make a list :

* Cloud name : Oracle Cloud Infrastructure (OCI)
* Virtual Machines : Core Instances
* Object storage : Object Storage Buckets
* Isolated network: Virtual Cloud Network
* Identity & Access : Identity & Security
* Queues/Messaging : Service Connector Hub
