Sentiment score
7.6
VMware Software Defined Data Center offers scalable, flexible solutions for managing both small and large-scale operations efficiently.
Monitoring, changing plans, and consolidating things are necessary parts of the process to avoid excessive costs.
Our company seeks cost-effective and more flexible open systems, and we find it difficult to integrate with third-party hardware.
On a scale of one to ten, I would rate the scalability of Azure Stack as eight.
 

Stability Issues

Sentiment score
7.7
Azure Stack is praised for stability and reliable support, offering strong service availability despite minor, manageable issues.
Sentiment score
8.0
VMware Software Defined Data Center is stable and reliable, with occasional issues and high ratings for ease of updates.
Since VMware created this software, when problems occur, we cannot handle them as we are not developers and need good support.
 

Room For Improvement

Azure Stack users seek enhanced feature parity, cost management, integration, technical support, AI capabilities, and user-friendly interfaces.
VMware needs to enhance upgrade processes, automation, usability, analytics, and pricing for better performance and user satisfaction.
Management looks for a balanced product that utilizes existing hardware, fulfills external customer demand, and leverages the scalability of the cloud model.
Many resources get created in Azure Stack, and managing those resources can be challenging.
The precision of anonymous activity tracking should be improved, particularly in identifying the correct location because IP information is sometimes inaccurate.
They need to improve their support because of new management, policies, and pricing, and they are not offering discounts.
 

Setup Cost

Azure Stack pricing varies widely, with mixed cost perceptions influenced by deployment specifics, service requirements, and regional complexities.
VMware SDDC is costly, but Hands-on Labs allow testing before purchase to assess its value.
If Microsoft lowers the price, more small businesses would be able to adopt the Enterprise E5 license.
 

Valuable Features

Azure Stack offers scalable, flexible solutions with integration, AI tools, and hybrid cloud features, enhancing deployment and development efficiency.
VMware's Software Defined Data Center simplifies management through centralization, offering virtualization, automation, high reliability, and cost-effective cloud integration.
They allow me to track all user activities.
I am very much impressed with Azure Stack, especially regarding security, complete compliance, data sovereignty, and data security.
We wanted to proceed with an integrated solution from the same cloud provider, so we are using Azure Stack.
The flexibility is excellent as we use storage policies, and whenever any VM or dynamic allocation is needed, it is automatically handled by VMware without physical intervention.

Security and compliance shine but integration and pricing need work
The difficulties we face involve the lack of support, which is one reason the product isn't selling well in the market. Perhaps it relates to our sales team's strategy, but management looks for a balanced product that utilizes existing hardware, fulfills external customer demand, and leverages the scalability of the cloud model. An improvement for Azure Stack would be in third-party integration; it feels very restricted and closed concerning hardware. For example, I have Dell EMC hardware, but I want to integrate it with other major hardware such as Cisco, IBM, Lenovo, or Supermicro, and I can't do that. They should also improve third-party integration regarding security and new services such as AI as a service. I expect more towards AI-enabled models, and GPU as a service is also not offered.
Naveen Malkani - PeerSpot reviewer
Have built a flexible virtual infrastructure for internal application hosting and optimized resource allocation
VMware vSAN, HCI is the best feature along with the VMware core suite of VMware ESXi servers. It is basically a part of HCI. In the networking part, VDS is valuable because NSX and similar solutions are required where telecom or multi-tenancy environments exist. Customers running single instances of networks with physical switches rely on actual throughput or load handling by physical switch buffer and memory chipsets. VMware Software Defined Data Center works but at a limited scale. We cannot completely grow or rely on VMware Software Defined Data Center. Though it is very helpful, we have removed entire server layers from the virtual server layer. The flexibility is excellent as we use storage policies, and whenever any VM or dynamic allocation is needed, it is automatically handled by VMware without physical intervention.
