OCI Health Check: 15 Essential Checks Before Going to Production

Introduction

Deploying workloads to Oracle Cloud Infrastructure (OCI) is only the first step. Before an environment goes live, administrators should verify that security, governance, networking, monitoring, backups, and identity configurations are correctly implemented.

This checklist summarizes 15 essential validations that every OCI administrator should perform before moving a production workload into operation.

1. Review Your Compartment Structure

A well-organized compartment hierarchy improves governance, simplifies administration, and makes permission management easier.

Consider separating resources into dedicated compartments such as:

• Production
• Development
• Test
• Network
• Security
• Shared Services

A good compartment strategy also helps with cost tracking and resource organization.

2. Validate IAM Policies

Review all IAM Policies before production.

Check that:

• Administrative access is limited.
• Users only have the permissions they need.
• Policies follow the Principle of Least Privilege.
• No unnecessary “manage all-resources” permissions exist.

Small policy changes can significantly improve security.

3. Enable Multi-Factor Authentication (MFA)

Every privileged account should use MFA.

Protect at least:

• Administrators
• Security teams
• Network administrators
• Billing administrators

MFA greatly reduces the risk of compromised credentials.

4. Verify OCI Cloud Guard

Cloud Guard should already be protecting your tenancy before production.

Confirm that:

• Cloud Guard is enabled.
• Targets are configured.
• Detector Recipes are active.
• Critical findings have been reviewed.
• Responder Recipes are configured when appropriate.

Cloud Guard provides continuous security monitoring across OCI resources.

5. Review Network Security

Inspect:

• Security Lists
• Network Security Groups
• Public IP assignments
• Internet Gateways
• Route Tables

Avoid exposing unnecessary ports such as SSH or RDP directly to the Internet.

6. Secure Administrative Access

Administrative access should never rely on unrestricted public endpoints.

Recommended options include:

• OCI Bastion
• VPN
• FastConnect
• Jump Servers

Restrict SSH and RDP access whenever possible.

7. Validate Backup Configuration

Verify that backups are configured for all critical resources.

Review:

• Boot Volume Backups
• Block Volume Backups
• Database Backups
• Backup retention policies
• Cross-region copies (if required)

Most importantly, perform a restore test to ensure backups are usable.

8. Review Disaster Recovery Strategy

Every production environment should have a documented recovery plan.

Confirm:

• Recovery Point Objective (RPO)
• Recovery Time Objective (RTO)
• Disaster Recovery architecture
• Recovery procedures
• Successful recovery testing

A documented plan is just as important as the technology itself.

9. Configure Monitoring and Alarms

Set alarms for important metrics such as:

• CPU utilization
• Memory usage
• Disk space
• Instance availability
• Load Balancer health
• Backup failures

Integrate alarms with OCI Notifications to ensure the operations team is alerted immediately.

10. Verify OCI Audit

OCI Audit records every management API operation.

Before production, verify that:

• Audit events are being collected.
• Administrators know how to investigate changes.
• Critical administrative actions are traceable.

Audit is essential for governance, troubleshooting, and compliance.

11. Enable Logging

Review whether logging is enabled for services that require operational visibility.

Examples include:

• VCN Flow Logs
• Load Balancer Logs
• Service Logs
• Application Logs
• Database Logs

Logging simplifies troubleshooting and security investigations.

12. Check SSL Certificates

Review every production certificate.

Validate:

• Expiration date
• Certificate chain
• Domain names
• Renewal process

Certificate expiration is one of the most common avoidable causes of service interruptions.

13. Review Costs Before Go-Live

Remove resources that are no longer required.

Look for:

• Unattached volumes
• Idle compute instances
• Unused public IPs
• Old snapshots
• Test load balancers

Cleaning up before production reduces unnecessary costs.

14. Apply Consistent Resource Tags

Tagging improves governance and financial management.

Example tags:

• Environment
• Application
• Owner
• Cost Center
• Criticality
• Backup

Consistent tagging makes automation and reporting much easier.

15. Update Documentation

Before production, ensure documentation includes:

• Architecture diagrams
• Network topology
• IAM Policies
• Compartments
• Backup procedures
• Disaster Recovery plan
• Operational runbooks

Good documentation reduces recovery time during incidents.

Conclusion

A successful OCI deployment depends on much more than infrastructure provisioning.

By performing these 15 validation steps before production, administrators can significantly improve security, operational readiness, governance, and long-term reliability.

This checklist can be reused for new deployments, migrations, and periodic health assessments, making it a practical reference for every Oracle Cloud Infrastructure administrator.
