OCI Certificate Manager

DB Realm Inc. (Internal)

Challenge

OCI Load Balancers require manual certificate updates, and Let's Encrypt certificates expire every 90 days — creating a recurring operational burden and risk of service disruption.

Solution

Built an automated certificate management system that handles Let's Encrypt certificate issuance, DNS-01 challenge validation via Route53, and automated deployment to OCI Load Balancer listeners and backend sets.

Results

  • ✓ Automated Let's Encrypt renewal
  • ✓ DNS-01 challenge via Route53
  • ✓ OCI Load Balancer auto-deployment
  • ✓ Zero-downtime certificate rotation
OCI Let's Encrypt TLS/SSL Load Balancer Automation

The OCI Certificate Manager eliminates the manual overhead of managing TLS certificates on OCI Load Balancers. It handles the full lifecycle — from Let’s Encrypt issuance through DNS validation to load balancer deployment — with zero downtime.

OCI Resource Reports

Managing OCI tenancies requires constant visibility into compute, networking, storage, and database resources — information scattered across the OCI console without a unified view.

Data for Good Calgary — Cloud Infrastructure

Data for Good Calgary's entire data platform — a 26ai Autonomous Database holding 17 schemas and six live APEX applications — sat in a personal OCI tenancy that Oracle had scheduled for reclamation. The chapter had a hard deadline, no budget for downtime, and no infrastructure team. Alongside it, the self-hosted platform stack running NextCloud, Mautic, DocuSeal and Collabora had no monitoring at all: the first sign of an outage was a volunteer reporting it.
