Diverse features and affordability drive effective resource management
Amazon EBS offers diverse features. It can be used for multi-purpose storage, supporting single, multiple, or heavy loads. It has different types for various use cases, allowing me to choose based on my specific requirements. The primary advantage of Amazon EBS is affordability compared to other solutions like EFS or FSX. It acts as a hard drive for servers, making it essential for operation.
MuhammadAzhar Khan - PeerSpot reviewer
Shared storage capabilities provide enterprise value with good reliability
Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.
