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.

Moving Resources

These resources provide detailed steps on how compartment changes impact resource access and management.

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 createthree 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.

Relevant OCI Documentation:

Capacity Reservations

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

RFC 1918 defines IP address ranges that are reserved for private networks, which cannot be routed on the public internet. In Oracle Cloud Infrastructure (OCI), these private IP address ranges can be used to create Virtual Cloud Networks (VCNs). The valid RFC 1918 CIDR prefixes include:

192.168.0.0/16: A private IP range often used in home networks.

10.0.0.0/8: A large private IP range commonly used in enterprise networks.

Invalid Options:

B. 0.0.0.0/0: This CIDR represents all IP addresses and is not a valid private IP range.

C. 192.268.0.0/24: This is not a valid IP address range as the octet "268" is outside the allowable range of 0-255.

TheInfrequent Access tierin OCI Object Storage is suitable for storing backups that need to be immediately accessible and retained for a specific period, such as 31 days, while also minimizing costs. This tier offers a balance between cost and accessibility, charging lower storage costs compared to the Standard tier but still allowing quick access to the data.

Use Case:The Infrequent Access tier is designed for data that is not frequently accessed but must remain readily available when needed, making it ideal for backup storage.

The primary purpose of the Web Application Acceleration service offered by Oracle Cloud Infrastructure (OCI) is tospeed up traffic on layer 7 HTTP load balancers. This service optimizes the delivery of web applications by reducing latency and improving response times, making it ideal for enhancing user experience on web applications.

Functionality:The service utilizes caching, compression, and other acceleration techniques to ensure that HTTP/S traffic is delivered efficiently.
