Hi Roshani,

When deploying Laserfiche on AWS, we do not generally recommend using Windows active/passive failover clustering for Laserfiche components. It adds lots of complexity for little benefit. Instead, do this:

• Configure EC2 Auto Recovery so individual instances automatically recover from failures.
• Use AWS Elastic Disaster Recovery (DRS) to continuously replicate your servers and volume data to a different Availability Zone (AZ) so you have the ability to fail the whole solution over to the secondary AZ. 
• Configure AWS Backup to perform at least daily backups because AWS DRS is a Disaster Recovery solution, not a backup solution.
• Optionally, use a Multi-AZ Amazon FSx for Windows File Server deployment to store repository volumes instead of EBS volumes attached to Laserfiche Server instances. Using EBS volumes protected with AWS DRS is likely cheaper and easier.
• Use Amazon RDS for SQL Server with a Multi-AZ deployment for multi-AZ high-availability at the database level.

Amazon EBS volumes (disks) are highly available and durable by design and automatically replicate your data across multiple storage servers in an AZ.
