OCI Cost Savings: Burstable Instances

Oracle Cloud Infrastructure’s burstable compute instances offer a powerful way to reduce costs for workloads that don’t consistently require peak CPU performance. By analyzing actual usage patterns with Checkmk and strategically implementing burstable instances, we achieved approximately 50% savings on OCI compute costs with no impact to service performance.

Breaking the Oracle Database Password Stalemate: A Solution That Actually Works

Many Oracle database application accounts still use default passwords or haven’t been changed in years due to the operational risk of breaking critical applications. Oracle’s Gradual Password Rollover feature (21c, backported to 19.12+) allows both old and new passwords to work simultaneously during transition periods, transforming high-risk password changes into controlled processes. This capability removes the main technical barrier that’s kept organisations from meeting password rotation compliance requirements.
