Cloud Computing Platforms: Alternative To OpenStack and Proxmox

Open source, despite popular misconception, does not imply that it is entirely free of cost. While open source software is often available at no monetary expense, it signifies a different ideology – the freedom to access, modify, and distribute the source code. 


Proxmox VE is a more user-friendly and accessible solution for smaller to medium-sized environments. It is easy to set up and manage, and it provides a comprehensive set of features for managing virtual machines and containers. Proxmox VE also includes its own built-in storage solution, which makes it a good choice for organizations that want to avoid the complexity of managing multiple storage backends.

  • Limited support: Proxmox VE is an open-source project, so there is no single vendor that provides support for the entire platform. This can make it difficult to get help when you need it.
  • Stability issues: Proxmox VE has been known to have stability issues, especially in large-scale deployments.
  • Security vulnerabilities: Proxmox VE has been known to have security vulnerabilities, which have been exploited by attackers.
  • Performance bottlenecks: Proxmox VE can be complex to optimize for performance. Organizations have experienced performance bottlenecks due to poorly configured components or inadequate hardware.


OpenStack is a more powerful and scalable solution for large-scale cloud deployments. It offers a wide range of features for managing virtual machines, containers, storage, networking, and more. OpenStack is also highly customizable, which allows organizations to tailor it to their specific needs. However, OpenStack can be complex to set up and manage, and it requires specialized expertise.

  • Complexity: OpenStack’s many components require correct configuration and management, which can be a challenge for organizations lacking expertise.
  • Cost: Large-scale OpenStack deployments can be expensive due to specialized hardware, software, and support requirements.
  • Security: OpenStack’s complexity exposes potential vulnerabilities. Proper configuration and security measures are vital for data and application protection.
  • Lack of support: As an open-source project, obtaining comprehensive support can be challenging.
  • Fragmentation: OpenStack’s size and complexity contribute to fragmentation within the community, making resource and support discovery difficult.

Warren is a turnkey cloud platform that can be used to offer a public cloud service. It includes everything from advanced IaaS features to hourly billing and day-to-day operations. This makes it a good choice for organizations that want to offer a public cloud service without having to invest in the infrastructure and expertise required to build and manage their own cloud platform.
Here are some of the benefits of using to offer a public cloud service:
  • Turnkey solution: is a complete solution that includes everything you need to offer a public cloud service, from the infrastructure to the billing and management system. This saves you the time and effort of having to build and manage your own cloud cloud platform and integrations like for instance billing and metering.
  • Advanced IaaS features: includes a wide range of advanced IaaS features, such as virtual machines, containers, block and object storage, networking and load balancing. This gives your customers the flexibility to choose the resources they need and to scale their applications up or down as needed.
  • Hourly billing: uses hourly billing, which makes it easy for your customers to pay for the resources they use. This is a more transparent and cost-effective billing model than traditional upfront pricing models of most “old school” hosting providers who charge you a month up front.
  • Day-to-day operations: platform prioritizes of all the day-to-day operations of your cloud service, such as easy live migration of provisioned resources, monitoring performance, and resolving issues. This frees you up to focus on other aspects of your business.

Which one is right for you?

If you are looking for a user-friendly and accessible virtualization management solution for a smaller to medium-sized environment, then Proxmox VE is a good choice. If you need a more powerful and scalable solution for a large-scale cloud deployment, then OpenStack is a better option.

Here are some additional things to consider:

  • Your budget: Proxmox VE is a free and open-source solution, while OpenStack can be more expensive, depending on the support options you choose.
  • Your skill level: Proxmox VE is easier to set up and manage than OpenStack, but it still requires some technical expertise. If you need a solution that is easy to use and maintain, then Proxmox VE is a good choice.
  • Your specific needs: If you have specific requirements for virtualization, storage, networking, or other features, then you should carefully compare the features of Proxmox VE and OpenStack to see which one better meets your needs.

Ultimately, the best way to decide which virtualization management platform is right for you is to carefully consider your specific needs and requirements.
