I would like to see an increase in the data upload limit, similar to DynamoDB, where there is no data limit.
The main concern is pricing, which could deter some customers; addressing this would enhance its appeal.
The system should move towards AI-driven optimization and enhance S3 object storage capabilities.
System downtime can disturb the entire ecosystem and impact all applications.

S3 offers multiple classes, allowing you to move data to cheaper classes for cost savings.
It is somewhat justified due to the benefits, but there is room for reconsideration.
Compared to buying three or four vendor solutions, it is much cheaper.
The cost has doubled for the same amount of data, which was a challenge when presenting use case justifications for the increased cost.
Nutanix Unified Storage (NUS) has definitely helped reduce our total cost of ownership.
 

Valuable Features

Featured Reviews

Vagner Martins - PeerSpot reviewer
Enhanced data security with seamless integration and static website capabilities
S3 is a great service offering numerous possibilities. It allows for storing objects and files of various types. I appreciate its capability to create static websites and integrate with services like CloudFront, EC2, and DynamoDB. Despite being focused on security, I leverage features such as cryptography and integration with CloudTrail.
Amarnath Charugundla - PeerSpot reviewer
Unified management and cost-effectiveness lead to positive experiences and future savings
Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.
