Functions in Oracle Cloud Infrastructure are great. As a serverless execution environment with pre-built logging, metrics, etc. it allows developers to simply focus on their code and not worry about all of the supporting infrastructure, while still providing a lot of flexibility through the use of container primitives. As great as Functions are, they are reactive, they can only be invoked and can’t natively be configured to be executed in a spontaneous or scheduled manner. Often this won’t matter, as Functions will be invoked directly or indirectly by users, or in response to events, but sometimes you simply need a bit of code to run periodically.Continue reading “A Better Mechanism for Periodic Functions Invocation?”
Simple, Secure Log Retention using OCI Services
Between the Oracle Cloud Infrastructure (OCI) Audit Service recording administrative operations and Oracle Identity Cloud Service (IDCS) tracking access and user management events, Oracle Cloud provides pretty comprehensive tracking of security events. Recently however, I have been in conversations with a number of organisations who have been seeking longer term retention of audit events for several different reasons, including governance, compliance and forensic requirements. The OCI Audit service supports requesting bulk export of audit events to Object Storage, which allows you manage the retention and archiving of those events yourself, so I started wondering if I could do the same for the IDCS access events. A bit of testing and some simple coding later, and I had events being pulled directly from the IDCS Audit Events API periodically and sent to Object Storage for retention.
In this blog post, I will provide this code as a sample, and discuss some of the techniques and technologies that are available in Oracle Cloud Infrastructure to enable simple, but highly secure and cost-effective, automation of cross-service tasks such as this.Continue reading “Simple, Secure Log Retention using OCI Services”
