Image is scanned for vulnerabilities via Trivy plugin.

Jenkins updates the K8s manifest and applies it to the staging environment.

Jenkins triggers a build on a specialized Windows or Linux agent with mainframe access.

Custom SSH scripts execute legacy compile commands.

Jenkins parses text-based build logs for errors.

Build artifacts are archived in a central repository.

Jenkins is installed on a private, non-internet-facing network.

Plugins are manually audited and uploaded via local file transfer.

Builds run on ephemeral agents that are destroyed after every run.

Audit logs are exported to a central SIEM for compliance monitoring.

A single Jenkins pipeline compiles the application binary.

Parallel stages are initiated for each cloud provider.

Artifacts are uploaded to S3, Azure Blobs, and GCS.

Jenkins triggers post-upload smoke tests in each cloud region.

Jenkins triggers a build every midnight.

Code is deployed to a dedicated performance environment.

JMeter or Locust tests are executed against the deployment.

Jenkins compares results with previous builds using the Performance Plugin.

If latency increases by >10%, the build is marked as unstable and alerts are sent.
