The Observability Gap
Most managed services provide "black box" observability:
- Managed Dashboards: Metrics are often aggregated or delayed, hiding the granular detail needed for deep troubleshooting.
- Proprietary Logging: Audit logs are often trapped within vendor-specific formats (like AWS CloudWatch or GCP Operations Suite), making multi-cloud compliance difficult.
- Control Plane Dependency: If you cannot access the cloud console, you lose visibility into the database's health.
PMM: The Bridge Between Architectures
Percona Monitoring and Management (PMM) serves as the unified observability layer that bridges the gap between cloud-native and traditional environments. Whether you use operators, use servers, or use both, PMM provides a consistent single pane of glass.
- Universal Monitoring: PMM collects deep-dive metrics from databases running on bare metal, virtual machines, or inside Kubernetes pods.
- Infrastructure Independence: Because PMM is self-hosted within your own trust boundary, your performance data remains yours. It does not live in a vendor’s database.
- Cross-Platform Visibility: You can monitor a legacy MySQL cluster on standard servers alongside a new PostgreSQL deployment on Kubernetes without switching tools or contexts.
Establishing a Sovereign Audit Trail
Compliance frameworks like DORA and GDPR require verifiable, identity-linked audit logs. To achieve this, you must decouple the audit trail from the infrastructure provider.
- The Database Level: Use the Percona Audit Plugin (available for MySQL and MongoDB) to capture every query, connection, and administrative action directly at the engine level.
- The Orchestration Level: If using Kubernetes, capture container lifecycle events. If using standard servers, capture OS-level access logs.
- The SIEM Integration: Route these logs into a centralized, customer-controlled SIEM (like Splunk or Elastic) using standard, portable protocols. This ensures your auditors have a continuous record that is independent of any cloud provider.
Implementation Checklist
To validate your observability sovereignty, complete the following steps:
- Deploy Independent Telemetry: Install PMM within your managed environment (cloud or on-prem) to begin collecting baseline metrics.
- Verify Data Residency: Configure your telemetry and logging agents to ensure that no metadata or audit logs are being leaked to the cloud provider’s internal monitoring systems.
- Simulate Visibility Loss: Disable access to the cloud provider’s management console. Verify that your team can still troubleshoot performance issues and access audit logs using PMM and your SIEM.
- Audit Evidence Automation: Create an automated report that pulls data from your independent observability pipeline to satisfy compliance requirements without manual vendor exports.
Strategic Outcome: Verifiable Isolation
By the end of this phase, your organization will have achieved Level 4 Sovereignty in observability
Your databases are no longer "silent" when you leave a vendor's ecosystem. You have the freedom to use operators, use servers, or use both, knowing that your visibility, security posture, and audit readiness remain constant.
