Study Notes

Oracle Cloud Infrastructure

Oracle Cloud Infrastructure (OCI) allows customers to use existing software licenses.
OCI offers free software licenses for certain services and discounts on new licenses.
Software licenses can be bundled with OCI services at a discounted rate.

Oracle Cloud Infrastructure Security Zones

Oracle Cloud Infrastructure Security Zones enforce best practice security configurations for resource management.
Security Zones provide a secure way to manage resources.

Data Transfer in Oracle Cloud Infrastructure

Ingress data transfer is generally free of charge in Oracle Cloud Infrastructure.
Data transfer costs are charged only for egress traffic to the internet.

Oracle Cloud Infrastructure Cost Analysis

Cost Analysis is a tool in Oracle Cloud Infrastructure that helps visualize and analyze cloud usage and spending patterns over time.
Cost Analysis helps track costs and optimize spending.

Oracle Cloud Infrastructure Compute

Oracle Cloud Infrastructure provides different types of Compute instances, including Virtual Machines (VMs), Dedicated Virtual Machine Hosts, and Bare Metal.
Nano instances are not a type of OCI Compute instance.

Compartment Quotas in Oracle Cloud Infrastructure

Compartment quotas are applied on a per-compartment basis in Oracle Cloud Infrastructure.
Quotas help control resource usage within a compartment.

Autonomous Database in Oracle Cloud Infrastructure

Oracle Cloud Infrastructure Autonomous Database provides a self-securing feature.
The self-securing feature in Autonomous Database provides enhanced security.

Regions and Availability Domains in Oracle Cloud Infrastructure

An OCI region has one or more availability domains.
Availability domains do not share infrastructure, such as power, cooling, or network, within a region.

High Availability in Oracle Cloud Infrastructure

To maintain high availability of an application, place components in different fault domains.
This ensures that the application remains available even in case of a fault domain failure.

Oracle Cloud Infrastructure Services

Oracle Cloud Infrastructure provides services like Oracle Database Service for Azure and Oracle Roving Edge Infrastructure.
Oracle MySQL Heatwave on AWS is not an OCI service.

Protecting against Failures in Oracle Cloud Infrastructure

Fault Domains can be used to protect against failures within an OCI availability domain.
Fault Domains help ensure high availability of resources.

Oracle Cloud Infrastructure Identity and Access Management

Compartments help isolate and control access to resources in Oracle Cloud Infrastructure.
Compartments can be nested, and a compartment is a logical collection of related resources.

Organizing Users in Oracle Cloud Infrastructure

Groups are used to organize multiple users into a team in Oracle Cloud Infrastructure Identity and Access Management.
Principals, Federation, and Policies are other components of OCI Identity and Access Management.

Resource Identification in Oracle Cloud Infrastructure

Resources in OCI are identified using OCID (Oracle Cloud Identifier).
OCID is a unique identifier for each resource in Oracle Cloud Infrastructure.

Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure

Virtual Cloud Network (VCN) peering allows communication between two VCNs in the same region or different regions.
Peered VCNs can exist in different OCI regions, but cannot have overlapping CIDRs.

Networking in Oracle Cloud Infrastructure

A Virtual Cloud Network (VCN) can reside only in a single region but can span multiple availability domains.
A VCN component that blocks inbound traffic but enables outbound traffic to the internet is a NAT Gateway.

Load Balancer in Oracle Cloud Infrastructure

The OCI Network Load Balancer supports Layer 4 (transport) traffic.

Storage in Oracle Cloud Infrastructure

Block Storage is associated with instances in the OCI Compute service.
Other types of storage include Object Storage, File Storage, and Archive Storage.

Autoscaling in Oracle Cloud Infrastructure

Autoscaling in an instance pool automatically provisions and removes instances.
Autoscaling can perform both metric-based and schedule-based scaling.

Oracle Cloud Infrastructure Pricing Models

Oracle Cloud Infrastructure supports pricing models like Pay As You Go, Bring Your Own License (BYOL), and Oracle Universal Credits.
Sovereign subscriptions are not a supported pricing model.

Data Transfer Costs in Oracle Cloud Infrastructure

Egress to the internet is charged under data transfer costs in Oracle Cloud Infrastructure.
Ingress is free, while egress is charged.

Budget Alerts in Oracle Cloud Infrastructure

Budget alerts can be set up to receive notifications when budget thresholds are reached.
Notifications can be sent via Email, Pager, or SMS.
