When you work with Oracle Cloud Infrastructure, one of the first steps is to set up a virtual cloud network (VCN) for your cloud resources.

VIRTUAL CLOUD NETWORK (VCN) :

A virtual, private network that you set up in Oracle data centers. It closely resembles a traditional network, with firewall rules and specific types of communication gateways that you can choose to use. A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice. See Allowed VCN Size and Address Ranges. The terms virtual cloud network, VCN, and cloud network are used interchangeably in this documentation. For more information, see VCNs and Subnets.

SUBNETS :

Subdivisions you define in a VCN (for example, 10.0.0.0/24 and 10.0.1.0/24). Subnets contain virtual network interface cards (VNICs), which attach to instances. Each subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. You can designate a subnet to exist either in a single availability domainavailability domain

or across an entire region (regional subnets are recommended). Subnets act as a unit of configuration within the VCN: All VNICs in a given subnet use the same route table, security lists, and DHCP options (see the definitions that follow). You can designate a subnet as either public or private when you create it. Private means VNICs in the subnet can't have public IP addresses. Public means VNICs in the subnet can have public IP addresses at your discretion. See Access to the Internet.

Live migration is the feature in the Oracle Cloud Infrastructure Compute service that enables users to migrate running instances between different physical servers. Live migration allows users to move instances without interrupting their workloads or affecting their availability.

Compartments do not provide a way to store and manage encryption keys and secrets in Oracle Cloud Infrastructure. Compartments are logical containers that help users organize and isolate their cloud resources. Compartments can be nested to create a hierarchy that reflects the structure of an organization or project. To store and manage encryption keys and secrets, users can use the Oracle Cloud Infrastructure Vault service, which is a fully managed service that provides centralized management of encryption keys, secrets, and certificates.

Object Lifecycle Management is the OCI Object Storage feature that can be used for the purpose of deleting any previous object versions 120 days after the object version transitions from the latest version to a previous version. Object Lifecycle Management allows you to create rules to automatically manage the deletion or archival of objects in a bucket based on predefined criteria, such as time, size, or name. You can use Object Lifecycle Management to reduce your storage costs and optimize your data management3

To achieve the desired outcome, you can create an Object Lifecycle Management rule that applies to all previous object versions in a bucket and specifies an age-based time rule that deletes objects 120 days after they become noncurrent versions. This rule will automatically delete any previous object versions that are older than 120 days from the date they were replaced by newer versions4

The other features are not suitable for this purpose. Pre-Authenticated Requests are a way to grant temporary access to your Object Storage resources without requiring users to have an Oracle Cloud Infrastructure identity. Pre-Authenticated Requests allow you to create URLs that can be used to access buckets or objects for a limited time period5 Retention Rules are a way to prevent objects from being deleted or overwritten for a specified period of time. Retention Rules allow you to create policies that enforce minimum retention durations for objects in a bucket or with specific prefixes. Retention Rules help you comply with regulatory or business requirements for data preservation6 Multipart Uploads are a way to upload large objects in parts rather than as a single operation. Multipart Uploads allow you to resume uploads, improve performance, and increase reliability for uploading large objects. Multipart Uploads help you overcome network or service disruptions during uploads7
