Proxmox VE and Spot by Flexera are competing products in the virtualization and cloud optimization space. Spot by Flexera seems to have the upper hand with its robust features and emphasis on cost efficiency and automation.
Features: Proxmox VE offers an open-source virtualization platform, virtual machine management, and container support, focusing on virtual environments. Spot by Flexera provides automated cost optimization, intelligent workload management, and multi-cloud integration, emphasizing cloud cost efficiency.
Room for Improvement: Proxmox VE could enhance its advanced feature set, simplify container integration, and improve its backup options. Spot by Flexera can focus on streamlining deployment processes, enhancing user interface complexity, and addressing pricing flexibility.
Ease of Deployment and Customer Service: Proxmox VE offers straightforward deployment with strong community-based support. Spot by Flexera presents a more complex deployment model but is complemented by comprehensive customer service, providing guidance for its extensive cloud management tools.
Pricing and ROI: Proxmox VE offers a competitive setup cost due to its open-source nature, leading to favorable ROI for budget-conscious organizations. Spot by Flexera has a higher upfront cost but delivers significant ROI through cost savings and resource efficiency in cloud environments.
A lot of money was saved after starting to use Spot by Flexera. I would say around 500,000 euros per year.
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.
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.
I would rate the customer support a nine out of ten.
We did not have to use it many times, but the few times that we did use it, it was very fast and very useful.
It is also a very easy tool to connect to different data sources and different servers since it is open source.
Spot's scalability is quite good, and it can be expanded to multiple environments.
In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used.
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.
We had a couple of IT assets that were not being used, and we had this information in our internal servers, but Spot by Flexera was not able to update on time.
Continuously making advancements based on customer feedback.
The pricing is reasonable and convenient, and the value it offers is completely in line with what I am spending.
I was aware of different pricing, setup costs, and licensing across the company.
Spot's automated cost optimization works by continuously analyzing the workload and applying policies to minimize cloud spend without sacrificing performance.
The fact that it can mix dozens of instance families dynamically is something which the AWS native autoscalers simply cannot do.
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.
