?? Introducing the Future of Log Analytics: Workspace Replication ??
Microsoft Azure has unveiled a game-changing feature for Azure Monitor Log Analytics: Workspace Replication! This innovative functionality provides unparalleled cross-regional redundancy, ensuring your monitoring capabilities remain robust and uninterrupted.
Workspace replication creates a replica of your workspace in a secondary region, ensuring cross-regional redundancy. The primary workspace in one region is actively mirrored to a secondary workspace in another region. If an incident impacts your primary workspace, you can trigger a failover to switch to your secondary workspace, ensuring continuous monitoring of your resources and applications.
- Cross-Regional Redundancy:Logs ingested after replication are sent to both primary and secondary workspaces.The secondary instance is created empty, and only new logs ingested post-replication are copied.
- Manual Switchover:Failover is manually triggered, giving you control over when to switch based on the severity of incidents.Use alert rules to notify when a switchover might be necessary based on ingestion latency, query success rate, or other health metrics.
- Active-Passive Setup:The primary workspace is active, while the secondary is updated in the background and cannot be directly managed or accessed.
- Cost-Effective:More affordable than dual homing, with billing per replicated GB.Control costs by applying replication to a subset of your Data Collection Rules (DCRs).
- Setup and Configuration: Enable replication using a REST API call to configure the secondary region. Replication applies to the workspace configuration, including schema and future changes. Replicated workspaces are updated asynchronously, ensuring minimal impact on ingestion latency.
- Failover and Failback: Trigger failover via a POST command, switching all ingestion and query requests to the secondary workspace. Once the primary workspace is healthy, trigger failback to resume normal operations. DNS rerouting ensures seamless transition between primary and secondary workspaces.
- Monitoring and Alerts: Create custom health indicators and alerts to monitor workspace performance. Use queries to measure ingestion latency, identify volume anomalies, and monitor query success rates.
- Restrictions and Limitations: Logs ingested before enabling replication are not copied to the secondary workspace. Workspace management operations (e.g., schema changes, retention policies) are only possible in the primary workspace. Replication is currently not supported for workspaces linked to a dedicated cluster or certain Azure Monitor experiences like Application Insights and VM Insights.
- Disaster Recovery:Ensure business continuity during regional outages by switching to the replicated workspace.Maintain seamless monitoring and alerting with replicated logs, even during primary region failures.
- Enhanced Monitoring:Protect against incidents impacting the entire region, beyond the scope of availability zones.Suitable for regions without availability zones or for customers requiring regional redundancy.
- Cost Management:Apply replication to specific Data Collection Rules (DCRs) to manage replication volume and related costs effectively.
In today's digital landscape, maintaining uninterrupted monitoring is crucial. Workspace replication ensures your logs are always available, mitigating risks associated with regional incidents. This feature is particularly valuable for organizations with stringent uptime requirements and those operating in regions without availability zones.
