OCI - Cloud Region and Availability Domain!
Oracle Cloud Infrastructure Console
The Console is an intuitive, graphical interface that lets you create and manage your
instances, cloud networks, and storage volumes, as well as your users and permissions.
See Understanding Compartments.
1. Oracle Cloud Infrastructure APIs
The Oracle Cloud Infrastructure APIs are typical REST APIs that use HTTPS requests and
responses. See "Using the API" in the Oracle Cloud Infrastructure User Guide.
2. SDKs
Several Software Development Kits are available for easy integration with the Oracle
Cloud Infrastructure APIs, including SDKs for Java, Ruby, and Python. For more
information, see "Developer Tools" in the Oracle Cloud Infrastructure User Guide.
3. Command Line Interface (CLI)
You can use a command line interface with some services. For more information, see
"Developer Tools" in the Oracle Cloud Infrastructure User Guide.
4. Terraform
Oracle supports Terraform. Terraform is "infrastructure-as-code" software that allows
you to define your infrastructure resources in files that you can persist, version, and
share. For more information, see Getting Started with the Terraform Provider.
5. Ansible
Oracle supports the use of Ansible for cloud infrastructure provisioning, orchestration,
and configuration management. Ansible allows you to automate configuring and
provisioning your cloud infrastructure, deploying and updating software assets, and
orchestrating your complex operational processes. For more information, see Ansible
Modules.
6. Resource Manager:
Resource Manager is an Oracle Cloud Infrastructure service that allows you to automate
the process of provisioning your Oracle Cloud Infrastructure resources. Using
Terraform, Resource Manager helps you install, configure, and manage resources
through the "infrastructure-as-code" model. For more information.
Most of Oracle cloud regions have 3 availability domains, each availability domain (physical building)
has three fault domains. A fault domain is a grouping of hardware and infrastructure within an availability
domain. Each availability domain contains three fault domains. Fault domains let you distribute your instances
so that they are not on the same physical hardware within a single availability domain. A hardware failure
or Compute hardware maintenance that affects one fault domain does not affect instances in other fault domains.
