Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.6
Spot by Flexera enabled substantial savings in compute costs and enhanced efficiency, though ROI may take longer for some.
Sentiment score
6.7
VMware vSphere boosts efficiency, lowering costs and hardware needs, ensuring rapid ROI and long-term financial benefits despite initial investment.
Our technology predicts demand, selects the cheapest instance mix, sizes the workloads appropriately, and scales it automatically based on policy, resulting in significant savings by reducing manual work and enhancing our flexibility, which has helped accelerate our deployments.
Global Hyperscaler Alliances Director at a tech vendor with 1,001-5,000 employees
I cannot share the exact number, but I can share the figure that my EC2 and EKS compute cost reduced by around 65 to 75% with Spot.
Dev Ops Engineer at a construction company with 11-50 employees
We can say 10% is the approximate amount of savings because most of the things are automated and streamlined, so the manual work is eliminated in most cases.

Stability Issues

Sentiment score
7.0
Spot by Flexera is mostly stable and reliable, though some users report occasional bugs indicating room for improvement.
Sentiment score
7.9
VMware vSphere is reliable, with issues mainly due to third-party hardware, and frequent updates enhance stability and performance.
It is a very stable hypervisor solution.
Manager of Solutions and Support at Esconet Technologies Pvt. Ltd.
While they are generally stable, if outages occur, they tend to be due to brands like HP or Dell, not VMware vSphere itself.
Revenue Operations Specialist at KK AGC
Mostly we don't have issues, but sometimes we have faced some stability issues because of some bugs and some CPU compatibility issues with Intel CPUs.
IT Director at Def Industry
 

Room For Improvement

Spot by Flexera needs OCI support, better multi-cloud integration, and UI improvements, though it's stable and mature.
VMware vSphere is costly and complex, facing performance, integration, and upgrade challenges, limiting accessibility for smaller enterprises.
Continuously making advancements based on customer feedback.
Global Hyperscaler Alliances Director at a tech vendor with 1,001-5,000 employees
Spot could be improved by adding features that help identify data to optimize storage costs by detecting datasets within our environment based on criteria such as age and usage.
AVP DevOps and Product Support at a recruiting/HR firm with 1,001-5,000 employees
More guided onboarding would help teams adopt advanced features faster.
Dev Ops Engineer at a construction company with 11-50 employees
The cost changed from perpetual to subscription, and there is a need for alternative solutions.
Manager of Solutions and Support at Esconet Technologies Pvt. Ltd.
Another area is the stability during upgrades from older versions to newer versions, where we face issues.
Manager of Systems at Sir Syed University of Engineering and Technology
Sometimes, it is difficult to find documentation for specific tools and solutions.
Server Support Engineer at CIPL - Corporate Infotech Pvt Ltd
 

Setup Cost

Enterprise users praise Spot by Flexera's pricing and setup, with structured management of licensing, via AWS Marketplace.
VMware vSphere's complex pricing offers flexibility and features, but businesses should evaluate needs to avoid unnecessary costs.
The pricing is reasonable and convenient, and the value it offers is completely in line with what I am spending.
Dev Ops Engineer at a construction company with 11-50 employees
Many customers are trying to avoid it due to its high cost.
Technical Assistant at EOCD
Costs significantly increased from perpetual to subscription, with prices rising by two to three times over three to five years.
Manager of Solutions and Support at Esconet Technologies Pvt. Ltd.
The solution is too expensive.
Revenue Operations Specialist at KK AGC
 

Valuable Features

Spot by Flexera offers cost optimization, Kubernetes management, and security compliance with intelligent autoscaling, AWS integration, and AI-driven insights.
VMware vSphere is praised for centralized management, cost efficiency, strong performance, scalability, and advanced features like vMotion and HA.
Spot's automated cost optimization works by continuously analyzing the workload and applying policies to minimize cloud spend without sacrificing performance.
Global Hyperscaler Alliances Director at a tech vendor with 1,001-5,000 employees
The fact that it can mix dozens of instance families dynamically is something which the AWS native autoscalers simply cannot do.
Dev Ops Engineer at a construction company with 11-50 employees
Spot helps us detect such changes within AWS at least one hour prior, allowing us to have a mitigation plan in place and host other servers within the same setup to avoid impacting the application.
AVP DevOps and Product Support at a recruiting/HR firm with 1,001-5,000 employees
The vMotion feature is beneficial for online migration of virtual machines from one host to another without downtime.
Manager of Solutions and Support at Esconet Technologies Pvt. Ltd.
The tool is highly available, which is crucial for implementing critical applications requiring 24/7 availability.
Revenue Operations Specialist at KK AGC
I always use VMware vSphere vMotion; we work with this feature all the time. vMotion is very useful; that's why we use the virtualization.

Featured Reviews

Dev Ops Engineer at a construction company with 11-50 employees
Intelligent autoscaling has cut compute costs and now manages ephemeral workloads efficiently
I think overall Spot is quite good. The UI is powerful, but it can feel a bit dense for some new users. More guided onboarding would help teams adopt advanced features faster, and deeper insights into Kubernetes resource usage would be beneficial. Overall, it is a really good platform that is quite mature and stable. I chose a rating of nine because it may sometimes be a bit overwhelming for newcomers, and there are also a few areas in which the EKS Kubernetes level granularity is a little missing. Overall, I think Spot is a really good and stable tool.
IA
IT Director at Def Industry
Has improved infrastructure monitoring and resource management but requires better support and cost efficiency
The high availability feature's resilience is not bad, but it could be better. For example, whenever you lose any hardware, you will have interruptions on the services, and it reboots again on the other hardware host which is available at the crash time. That's good, but we would prefer to have zero downtime instead of the rebooting on the other server. We would prefer to have a zero downtime always-on configuration. VMware vSphere has a built-in feature called Fault Tolerance, but it's very limited for very limited VMs or very limited core count or CPU count, so it's not so useful for all the environment because of the limitations. The Fault Tolerance (FT) feature is very limited to very little core counts or very little VM counts, so you can't run the Fault Tolerance for all the servers or all the VMs, and that's very bad. If VMware vSphere could have any kind of built-in patch management environment with a repository, offline repository option, with test, non-production, and production environment separated, this would be perfect. Management of patch management with operating systems and including third-party applications which are running on the servers would enhance the VMware vSphere environment. VMware vSphere is very expensive. The worst aspect of VMware vSphere is the price. I can't tell you the exact cost at this time because the other team members in my teams are working on it, but I remember that the prices are very high. VMware vSphere is easy to scale, but it could be better, similar to a Kubernetes environment. It should have an automatic scale-out feature when the load gets high; if it gets some scale out automatically, it would be better than this, similar to Kubernetes or OpenShift.
