Likelihood to Recommend K8s should be avoided - If your application works well without being converted into microservices-based architecture & fits correctly in a VM, needs less scaling, have a fixed traffic pattern then it is better to keep away from Kubernetes. Otherwise, the operational challenges & technical expertise will add a lot to the OPEX. Also, if you're the one who thinks that containers consume fewer resources as compared to VMs then this is not true. As soon as you convert your application to a microservice-based architecture, a lot of components will add up, shooting your resource consumption even higher than VMs so, please beware. Kubernetes is a good choice - When the application needs quick scaling, is already in microservice-based architecture, has no fixed traffic pattern, most of the employees already have desired skills.
Read full review We used Proxmox to implement private cloud services, for clusters of a small number of servers, from 3 to 11 with and without high availability. Allways with ZFS file systems, and we used to install the root pool in SSDs mirrored and use other pools with RAID 10 in groups of four, for the virtual machines and containers, for the backups and snapshots, we used magnetic disks with RAID 10, in groups of four. Do not use an even number of servers because does not facilitates the implementation of High Availability, because the corosync service must have an odd number of servers to detect a failed server for the quorum system. We used a variety of servers, from clone PCs with AMD Ryzen with 6 cores and 12 threads with 64 GB of RAM no ECC, to high end servers with 64 cores and 128 threads per cpu and 2 cpus per server, with AMD EPYC Rome or Milan, 2 terabytes of RAM ECC.

An exclusive server for BackUp Administration (PBS) Hardware Customization. You can select several properties to adapt the hardware to your needs Easy administration. You will be able to manage the server with easily accessible tools such as the web console and usage statistics. Certificates Administration. Read full review Cons Local development, Kubernetes does tend to be a bit complicated and unnecessary in environments where all development is done locally. The need for add-ons, Helm is almost required when running Kubernetes. This brings a whole new tool to manage and learn before a developer can really start to use Kubernetes effectively. Finicy configmap schemes. Kubernetes configmaps often have environment breaking hangups. The fail safes surrounding configmaps are sadly lacking.

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.
Read full review Usability Out of every product I have used for this, Proxmox VE is the most concise, clear, and functional I have ever seen. I continue to use Proxmox VE even after occasionally comparing alternatives available because of it's usability, design concept, and great support of features. It's very unlikely I will find a product that can even compete with Proxmox VE in every angle of what Proxmox VE provides.
Read full review Reliability and Availability 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.
Read full review Performance 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
Read full review Support Rating They are fast, understanding, very intelligent, know their product very well, fast, responsive, and concise. Need I say more?
Read full review Implementation Rating It worked, was easy and super fast to deploy, and provided everything we needed in a matter of minutes
Read full review Alternatives Considered Most of the required features for any orchestration tool or framework, which is provided by Kubernetes. After understanding all modules and features of the K8S, it is the best fit for us as compared with others out there.
Read full review Proxmox VE is cheaper than VMware, especially upscaling an HA architecture. Compared with other free or less expensive solutions, Proxmox VE is high compatible with more types of hardware solutions and more VM types. From my point of view, Proxmox VE has no competitor at the same price level, it offers the most complete and production-ready HA solution.
Read full review Scalability 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.
Read full review Return on Investment Because of microservices, Kubernetes makes it easy to find the cost of each application easily. Like every new technology, initially, it took more resources to educate ourselves but over a period of time, I believe it's going to be worth it. Read full review Proxmox has allowed to us to do more with less. We can invest in a single (or multiple if clustering) host with a decent specification, and run most of our infrastructure on it. Open source technologies allowed us to re-use previous skills and knowledge. There was very little onboarding required because we already knew Debian, KVM, ZFS, etc. Virtualisation has vastly reduced the amount of time required to maintain all our systems. Everything is so much more organised and lends itself to automation (with Ansible, in our case). Read full review ScreenShots
