Proxmox VE vs. Zoho Mail

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.

If you don't have a huge budget and want something that works with minor quirks here and there then Zoho Mail is definitely something you should look into. For half the price of Google G Suite or Office account you get 5GB of storage per user and can send up to 25MB emails without restrictions. Great for small businesses in my opinion. I have had some issues with their spam filter, but we use SpamTitan and just shut off the one that comes with Zoho Mail. Zoho's spam filter isn't horrible but you should definitely use something in addition or instead of what comes with Zoho.

• BackUp System, provides extensive propiertes and verifications. 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.

• I really like that there is a free version in which a single user can be created. It is really useful because it allows you to evaluate each characteristic of the service without having to buy it.
• I also really like the visual aspect of the inbox, which is partially customizable. Because you can make small changes such as changing the color, the language, and among other things.

• 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.

• It does allow for notifications for various things, but I am not sure where to turn them all off
• It only counts to 9 the unread email alert, then says 9+
• Overall I don't think there is much they need to work on.

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

It is very easy to use and does all you need. It sends newsletters to their own folder. A notification folder for more important things. The Spam folder collect the right amount of spam emails

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.

I have spoken with Zoho several times and their support is always friendly and helpful. I have always been asked for security pins and codes when seeking assistance which helps me to feel my accounts are secure and I have never had to wait on hold to speak with someone for more than 5 minutes. They always seem to have someone available to help. If you call asking for instructions on how to do something they gladly walk you through the process and if you just need something done and don't have time to do it yourself they will happily customize whatever you need without you having to spend all day with it.

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.

Zoho is free. Also, there is no need for a separate IT guy for creating mail, or if any issues come you don't have to find anyone anyone can check and fix all issues from their super admin panel. Zoho overview is much better than outlook and its appearance of getting mail popup and functionality is better than outlook. My friend suggested for this and also after using I have referred my friend

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.
