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.
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 have seen a return on investment as I was able to reduce my compute cost by 60 to 65% for some of my applications that needed light temporary processing tasks with ephemeral storage and stateless applications.
I would rate the customer support a nine out of ten.
Spot's scalability is quite good, and it can be expanded to multiple environments.
Continuously making advancements based on customer feedback.
More guided onboarding would help teams adopt advanced features faster.
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.
The pricing is reasonable and convenient, and the value it offers is completely in line with what I am spending.
Spot's automated cost optimization works by continuously analyzing the workload and applying policies to minimize cloud spend without sacrificing performance.
My compute costs have reduced, capacity and production output have increased, and my overhead for maintaining custom scripts or doing some of the tasks manually has been saved.
One use case we plan to implement within the next few months is the overall commitment savings, which we used to manage manually, but with Spot, it automatically helps us detect when and what kind of instances to purchase, making it easier for us to manage our overall commitment for the savings plan.

Proxmox VE is a complete virtualization management solution for servers. It is a powerful open-source platform and supports two virtualization technologies - KVM (Kernel-based Virtual Machine) for virtual machines and LXC for containers. Proxmox VE has a central user interface that allows you to manage not only VMs and containers, but also storage resources, network configuration, and high availability for clusters. It is enterprise-ready and is valued for its scalability and maximum flexibility, enabling you to virtualize very demanding workloads. Proxmox VE makes it possible for you to easily install, manage, and monitor hyper-converged (HCI) data centers.
Proxmox VE Key Features
The Proxmox VE platform has many powerful features, including:
pen-source software, high-available clusters, command line, fencing, a web-based management interface, flexible storage options, REST API, live/online migration, storage replication stack, software defined storage, virtualized networking, backup and restore, two-factor authentication, role-based administration, and VM templates and clones.
