In Oracle Cloud Infrastructure (OCI), to ensure high availability and distribution across Availability Domains (ADs), the recommended approach is as follows:

Capacity Reservations for High Availability: To achieve high availability, especially across all three Availability Domains in a region, you should create three capacity reservations. Each reservation corresponds to one AD, ensuring that your instances or resources are evenly distributed and resilient to AD-level failures.

Why Three: This setup provides redundancy and load distribution across the ADs, meeting the high availability requirements.

Capacity Reservations

This document outlines how to create and manage capacity reservations to meet high availability and fault tolerance requirements.

OCI Confidential Computing is a security feature designed to protect data in use. This is particularly important for sensitive workloads where data must be secured not only when at rest or in transit but also while being processed.

Encrypts and Isolates In-Use Data: OCI Confidential Computing ensures that data and the applications processing it are isolated from the underlying infrastructure. This means that even if the infrastructure is compromised, the in-use data remains secure. The technology typically leverages secure enclaves or other hardware-based isolation mechanisms to achieve this.

Other Options:

Optimizing Network Performance (A), Automatic Scalability and Load Balancing (B), and Secure Data Storage (D) are important features, but they are not related to the core capabilities of Confidential Computing, which focuses on in-use data protection.

OCI Confidential Computing Overview

This documentation provides a detailed explanation of how OCI Confidential Computing works and its benefits for securing sensitive data during processing.

In Oracle Cloud Infrastructure (OCI), when you need a full-featured Identity-as-a-Service (IDaaS) solution, the appropriate Identity Domain type to create is Premium.

Premium Identity Domain: This option provides a comprehensive set of identity and access management (IAM) capabilities, including advanced security features, identity governance, and support for enterprise-grade integrations. It supports managing user identities, multifactor authentication, and various other identity services required for a robust IDaaS solution.

Other Options:

External User: This is a limited domain type typically used for managing users who only need access to specific external services.

Free: This domain type offers limited features and is not intended for full-featured enterprise IAM requirements.

Oracle Apps Premium: This is tailored for integrating with Oracle applications but does not offer the broad capabilities of the Premium option.

This documentation explains the various identity domain types and their use cases within OCI.

In Oracle Cloud Infrastructure (OCI), when you move a database instance to a different compartment, the following impact on user access occurs:

Impact of Moving Resources: When you move a resource, like a database instance, to a different compartment, the IAM policies that grant access to that resource in the original compartment no longer apply. This effectively revokes access for users or groups unless equivalent policies are in place in the new compartment.

Restoring Access: To restore access, you would need to create new IAM policies in the destination compartment that grant the necessary permissions to the users or groups who need access.

In Oracle Cloud Infrastructure (OCI) File Storage, when you overwrite a portion of a file, the service does not immediately reclaim the space occupied by the previous version of the file. The total meteredBytes reflects both the original data and the new data written.

Scenario Explanation: You start with a 1 GB file. When you overwrite 0.5 GB of this file, the file system retains both the 0.5 GB of the original file and the new 0.5 GB you wrote.

Calculation: The original 1 GB file contributes 1 GB to meteredBytes. When 0.5 GB is overwritten, the total usage becomes 1.5 GB (1 GB original + 0.5 GB new).

Thus, after the hourly update cycle, the total meteredBytes shown by the File Storage service will be 1.5 GB.
