A company utilizes a Grafana data visualization solution running on a single Amazon EC2 instance to monitor the health of its AWS infrastructure. The company has invested significant time and effort into creating custom dashboards that must be preserved. These dashboards require high availability and must not be offline for more than 10 minutes. The company seeks to minimize ongoing maintenance efforts. Which solution offers the least operational overhead while meeting these stringent requirements?
Explanation:
The correct answer is B. Creating an Amazon Managed Grafana workspace and configuring a new Amazon CloudWatch data source, then exporting the dashboards from the existing Grafana instance and importing them into the new workspace, offers the least operational overhead. This solution leverages a fully managed service, ensuring high availability and reducing maintenance tasks. Options A, C, and D involve more manual setups and maintenance, which do not align with the requirement to minimize ongoing maintenance efforts.
