In today's post, we are going to talk about compute instances in OCI. First of all, what is a compute instance? A compute instance is the OCI resource that you must deploy to provision and manage compute hosts. So, If you have the requirement to create a Virtual Machine (VM) or an infrastructure to host your application then you must use Compute Instance service. OCI offers 2 flavours: Bare Metal: Physical server without any virtualisation. Direct access to the hardware. The user has to manage the virtualisation layer, as well as the rest of the layers: OS, App Container, code... It is a Single-Tenant Model, i.e. dedicated to only one client. It does not share hardware with other clients. Virtual Machine: It is basically a Bare metal with a virtualisation layer (which is taken care of by the Cloud Provider). Therefore, it has a hypervisor where it can run VMs smaller than the BM. It is based on a Multi-Tenant model. OCI also offers different shapes depending on the requi...
