## What Is Included

• Oracle Database 21c XE pre-installed and configured for immediate use
• Oracle Enterprise Linux 7 as the base operating system
• Pre-configured Oracle Net listener on port 1521
• 24/7 support with guaranteed 24-hour response time from cloudimg

## Oracle21c XE Resource Limits

Oracle Database 21c XE is a free-to-use edition with the following built-in resource constraints:

• Maximum2 CPU threads
• Maximum 2 GB RAM allocated to the database instance
• Maximum 12 GB of user data storage

These limits make XE ideal for development, testing, prototyping, and small departmental workloads rather than large-scale production environments.

## Ideal Use Cases

• Development and prototyping: Application developers building Oracle-based solutions can use this AMI as a cloud-hosted dev/test environment before migrating to Standard or Enterprise Edition for production.
• Small business departmental apps: Teams running inventory systems, CRM modules, or financial reporting tools that fit within XE resource limits benefit from Oracle's reliability without Enterprise licensing costs.
• Database training and evaluation: DBAs and students evaluating Oracle features or preparing for certification can launch a ready-to-use instance without manual setup.

## AWS Integration Points

• Amazon S3: Configure RMAN backups to S3 for durable, cost-effective database backup storage.
• Amazon CloudWatch: Monitor instance health, CPU utilization, and disk I/O metrics for your Oracle database host.
• AWS Systems Manager: Manage patching and configuration of the underlying OEL 7 operating system.
• Amazon EBS: Use provisioned IOPS or gp3 volumes for predictable database storage performance.

## Security Considerations

The AMI is built with security in mind. Oracle21c XE supports Transparent Data Encryption (TDE) for data at rest and Oracle Net encryption for data in transit. We recommend buyers configure VPC security groups to restrict port 1521 access to trusted IP ranges and enable SSH key-based authentication only.

## Getting Started

1. Subscribe to this AMI from AWS Marketplace.

2. Launch an EC2 instance (minimum recommended: t3.medium or larger with at least 4 GB RAM for OS overhead plus database usage).

3. Configure your security group to allow inbound TCP on port 1521 (Oracle listener) and port 22 (SSH).

4. Connect via SSH using your key pair.

5. Access the database using SQL*Plus or Oracle SQL Developer with the credentials provided in the Usage Information section.

A comprehensive user guide with step-by-step deployment instructions is available in the Usage Information section of this listing.
