ROI

Sentiment score
7.0
Organizations achieved 300% ROI with Amazon S3 Glacier through infrastructure savings, improved efficiency, and resource reallocation, despite support challenges.
Sentiment score
7.6
Nutanix Unified Storage offers significant cost savings, enhanced productivity, and scalability, improving resource allocation and disaster recovery capabilities.
If AWS improves support and cost management, there would be fewer reasons for users to consider other cloud platforms.
As it is Amazon S3 Glacier, it is used only for archival purposes, so it is comparatively okay to use it, and we can save money compared to the standard which is high.
For me, the biggest return on investment when using this solution is that we do not have to have much support staff to run it.
The scalability challenge with previous systems is lessened with Nutanix since we can expand by adding new hardware without needing migrations.
We are saving approximately 20% to 25% compared with the competition.
 

Customer Service

Amazon S3 Glacier support is mixed: efficient assistance but variable response times, sufficient documentation, and varied support levels impact experiences.

8.0
Nutanix Unified Storage support is praised for responsiveness and knowledge, with high satisfaction despite occasional delays for complex issues.
There is room for improvement in providing more skilled and comprehensive solutions.
They provide documentation and resolve issues.
If it is a business plan, then the support we have is really good.
They come on the call, start troubleshooting immediately, and resolve issues effectively.

I would give the customer service and technical support a ten out of ten.

It automatically triggers tasks, causing performance issues.
 

Room For Improvement

Amazon S3 Glacier needs improved speed, security, compliance, pricing clarity, user experience, support, cost efficiency, and interface usability.
Nutanix Unified Storage needs better simplicity, security, integration, cost efficiency, support, and improvements in interface, protocols, and analytics.
I would like to see improvements in the transfer rate as it takes quite a long time to retrieve data from Glacier compared to standard S3 storage.
Support could be more robust, with a focus on providing comprehensive solutions even for novel issues.
Another improvement is making Glacier available in all regions.
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.
 

Setup Cost

Amazon S3 Glacier provides cost-effective data archiving, though pricing complexity raises concerns despite lower initial costs and operational flexibility.
Nutanix Unified Storage offers competitive pricing, valued for performance and flexibility, but can be costly for smaller businesses.
Compared to competitors like GCP, AWS can work on reducing hidden costs and overall pricing to retain startups and medium-sized businesses.
The storage cost is minimal, which is beneficial for archival purposes.
While it's generally cost-effective, the pricing model could be clearer.
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.

Featured Reviews

ArunDhwaj - PeerSpot reviewer
Versatile data storage improves security and supports increasing data volumes
Amazon S3 Glacier offers robust security features and practically infinite storage, where we can store all kinds of media swiftly. It supports various data types, including semi-structured and raw formats. These features facilitate log management and data dumping since the service is versatile enough to handle large volumes of data and provide necessary security.
Vipin Kumar Sha - PeerSpot reviewer
Pricing challenges overshadow efficient data handling and fast deployment
In terms of improvement areas for Nutanix Unified Storage (NUS), pricing is a significant issue, and another aspect is that the export of Nutanix backups does not support CD-ROMs, which is a disadvantage. Currently, it only supports QZ bus types for backups, which limits compatibility. When comparing Nutanix Unified Storage (NUS) with other solutions in the market, it falls short because it only supports iSCSI backups, while competitors also support QZ, iSCSI, fiber channel, and NVMe storage. The solution requires no maintenance for patching since it is designed effectively, but Nutanix Unified Storage (NUS) does not support fiber channel connectivity or external attached storage through NAS, limiting its compatibility. Additionally, technical support response time and efficiency are lacking in comparison to competitors.
