CloudFoundry vs. Proxmox VE

It's well suited if:

• The organization has large number of applications that needs to be deployed frequently.
• The organization is tied to the DevOps mindset.
• The organization has programs in different languages.
• The applications does not need EJB's support that servers like web logic provide.

It's less suited if:

• The applications needs security configuration within the same CloudFoundry instance.
• The organization, for whatever reason does not want developers to manage the instances.

Proxmox VE is a virtualization platform that provides a range of features and functionalities suitable for various scenarios. Here are some specific scenarios where Proxmox VE is well suited and some scenarios where it might not be the best choice:Well-suited scenarios:Virtualization of server workloads: Proxmox VE is well suited for virtualizing server workloads such as web servers, mail servers, database servers, and other similar applications. Its high-performance virtualization capabilities allow these workloads to run smoothly and efficiently.Hosting multiple virtual machines (VMs): Proxmox VE is ideal for hosting multiple VMs on a single server. It provides efficient resource management, allowing users to easily allocate resources to each VM.Clustered environments: Proxmox VE is a great choice for clustered environments. It supports clustering and can easily manage multiple servers, providing high availability and load balancing for mission-critical applications. Less appropriate scenarios: Limited hardware resources: Proxmox VE requires significant hardware resources to run efficiently. If you have limited hardware resources, it might not be the best choice. Simple applications: If you only need to run a single, simple application, Proxmox VE might be overkill. Other virtualization platforms or even a basic web hosting service might be more appropriate.

• Support for Orgs and Spaces that allow for managing users and deployables within a large organization.
• Easy deployment, deploying code is as simple as executing single line from CLI, thanks to build-packs.
• Solid and rich CLI, that allows for various operations on the instance.
• Isolated Virtual Machines called Droplets, that provide clean run time environment for the code. This used to be a problem with Weblogic and other application servers, where multiple applications are run on the same cluster and they share resources.
• SSH capability for the droplet (isolated VM's are called droplets), that allows for real time viewing of the App code while the application is running.
• Support for multiple languages, thanks to build-packs.
• Support for horizontal scaling, scaling an instance horizontally is a breeze.
• Support for configuring environment variable using the service bindings.
• Supports memory and disk space limit allocation for individual applications.
• Supports API's as well as workers (processes without endpoints)
• Supports blue-green deployment with minimal down time

• ZFS storage out of the box. The integration with ZFS is fantastic. You can easily create pools to store your VM images and data on, and the Proxmox web UI provides an easy way to check drive health, ZFS scrub status, etc.
• Great web UI. Practically everything configurable is available to do so from the web user interface. You'll rarely need to drop to the command line for administrative tasks, unless you want to, in which case you can do that too. The UI also provides graphs and visualisations to help you keep check of how everything is performing.
• Easy to setup a high availability cluster. Although Proxmox VE works perfectly well on a single server, you can also install it on multiple hosts and setup a cluster.
• Uses a Debian core system with an Ubuntu based kernel. This means everything to do with the base operating system is tried and trusted. We use a lot of Debian and Ubuntu installs, so having this run underneath Proxmox VE was an added bonus for us.

• Does not support stateful containers and that would be a nice to have.
• Supports showing logs, but does not persist the logs anywhere. This makes relying on Cloud Foundry's logs very unreliable. The logs have to be persisted using other third party tools like Elk and Kibana.

• The web UI does not work as well on mobile devices. It is useable, but a mobile optimised / responsive UI would be nice to have. There is a mobile app, so that may alleviate this issue, but I have not yet tried it.
• Support in the community forums could be better. There are paid support plans, but new users trying out the software will not have access to this. Answers to questions can sometimes be terse, and I can imagine this may put some people off.
• The wiki is a bit hit and miss with certain topics. I've often seen outdated or missing information, and the whole thing looks like it could do with some polish. I'd love to see it opened up for the community to add to.

Proxmox VE provides the most capable, yet stable virtualization platform in the market today. Licensing options are also competitive and cost-effective for support, and support is extremely fast and knowledgable of getting issues resolved as quickly and soundly as possible.

The interface is easy to use for most of it, but still lacks screens for some configurations. Also, a few of the screens are not as intuitive as they could be. This is specially true with disk and network configuration, where some graphic/visual representations of the configurations would be very useful

Proxmox VE's ha-cluster functionality is very much improved, though does have a not-very-often occurrence of failure. In a 2-node cluster of Proxmox VE, HA can fail causing an instance that is supposed to migrate between the two nodes stop and fail until manually recovered through the command-line tools provided. Other than this, the HA clustering capability of Proxmox VE has proven to be reliable in 3 or more clustered environments with much less chance of these failures to occur.

Proxmox VE's interfacing is always fast to load, both the Web interface and the command-line tool interfaces. Reporting is practically real time almost all the time, and you can see everything in mere seconds, easily able to identify if something is wrong or it everything is in tip-top shape as always desired

They are fast, understanding, very intelligent, know their product very well, fast, responsive, and concise. Need I say more?

It worked, was easy and super fast to deploy, and provided everything we needed in a matter of minutes

While Docker shines in providing support for volumes and stateful instances, Cloud foundry shines in providing support for deploying stateless services. Heroku shines in integrating with Git and using commits to git as hooks to trigger deployments right from the command line. But it does not provide on-premise solution that Cloud foundry provides.

Proxmox Virtual Environment is better, less costly, it has better CAPEX and OPEX, is open source and more robust and flexible.

It is an agnostic product, one can use a PC clone or a high end server to install it, and it works flawlessly on both.

The product has a large life cycle, is stable and has few problems and vulnerabilities than the other propietary products.

Proxmox VE provides everything you need to quickly add new storage mediums, network and local, as well as networking interfaces, such as using Linux standard bridges and now Open-vSwitch bridges which can be even more scalable than before. Proxmox VE 4.0 dropped support for OpenVZ in favor of the more well supported and native LXC and made an upgrade path to it very simple.

• Positive impact, since it simplifies the deployment time by a huge margin. Without cloud foundry, deploying a code needs coordination with infrastructure teams, while with cloud foundry, its a simple one line command. This reduces the deployment time from at least few hours to few minutes. Faster deployments promote faster dev cycle iterations.
• Code maintenance such as upgrading a Node or Java version is as simple as updating the build-pack. Without cloud foundry, using web logic, the specific version only supports a specific version of Java. So updating the version involves upgrading the version of web logic that needs to involve few teams. So without cloud foundry, it takes at least few days, with cloud foundry, its a matter of few mins.
• Overall, happier Developers and thats harder to quantify.

• Due to the open source nature of Proxmox, we have no licensing costs while training our employees
• We've migrated 100% of our clients to Proxmox and have found improved uptime, and flexibility.
• In the 10 years of using Proxmox, we've yet to lose any data or not be notified of backup issues.
