An organization plans to deploy Instana Standard Edition on-premises to monitor a 500-host production environment. The infrastructure team must size the backend server correctly before procurement. Which hardware configuration represents an appropriate baseline for this deployment scale?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Instana Standard Edition handling 500 monitored hosts generates substantial telemetry volumes that require significant compute resources and fast storage for time-series data ingestion and query workloads. A baseline of 16 CPU cores with 64 GB RAM and NVMe SSD storage appropriately balances cost and performance at this scale. Undersizing with insufficient CPU or slow spinning-disk HDD storage leads to data ingestion lag, dropped spans, and degraded UI query responsiveness.

Full Explanation
Instana Standard Edition handling 500 monitored hosts generates substantial telemetry volumes that require significant compute resources and fast storage for time-series data ingestion and query workloads. A baseline of 16 CPU cores with 64 GB RAM and NVMe SSD storage appropriately balances cost and performance at this scale. Undersizing with insufficient CPU or slow spinning-disk HDD storage leads to data ingestion lag, dropped spans, and degraded UI query responsiveness. The correct answer is '16 CPU cores, 64 GB RAM, and 1 TB NVMe SSD storage'. The incorrect options — '8 CPU cores, 32 GB RAM, and 500 GB SSD storage', '4 CPU cores, 16 GB RAM, and 250 GB SAS HDD storage', '32 CPU cores, 128 GB RAM, and 4 TB NVMe SSD storage' — are wrong because they do not align with IBM Instana's architecture or recommended practices for this scenario. Understanding this concept is essential for the Domain 3: Installation domain of the IBM Instana Observability certification.
