Ok, so there are worse options than Broadcom's VMWare...
...I forgot about these guys. I guess Xen is still sort of a thing.
Vates, the developer behind Xen Server fork XCP-NG, has thanked Broadcom for increasing interest in its work, and criticized Citrix for presenting challenges to its efforts. In a post announcing version 8.3 of the platform, CEO and co-founder of Vates, Olivier Lambert, wrote that the success of the 8.x series "has been a game …
Well, I would previously have agreed with the comments above but we've completed a migration from VMware to XCP-ng and I have to say, it's very good. We paid for support, which is an annual cost. The system is free of licence costs. The support team is brilliant, very quick response with info that is accurate and gets the issue resolved.
There is no difference in speed between runnong VMs on VMware and XCP-ng. We have Debian, Windows and Centos VMs and 16 core Postgres instances for examle run as fast on XCP-ng as they did on VMware. The rolling pool update works well, the migration speed is perhaps slightly slower for large VMs but the backup even backs up direct to AWS S3 or Wasabi immutable with S3 compatibility. Version 8.3 also includes better compression for migrations and backups which will help. I was even able to migrate an old Windows 2008R2 VM from Vmware to XCP-ng without adding any additional drivers and it works. Maybe not advisable but got me out of a hole !
Overall, it was a rocky start before we understood the requirements - there are some which do not apply to VMware, such as using the same NIC number on each host for the same thing, but once you understand how it works (I've been VMware since 2006) it's very easy and it's one of those products that 'does what it says on the tin'.
We have just over 100 VMs with two SaaS products with about 600 customers and maybe 40,000 users. Use quality hardware and it is really very little different to VMware as far as a smaller enterprise is concerned. I'm not sure how it would run with 1000 VMs but I suspect it wold be the same as it is with 110.
I'd strongly recommend watching lots of videos on YouTube, do lots of reading and set up a test system first, with the support from Vates. Just as you would if you were approaching VMware for the first time !
awesome!!!
for any peoples with a hundred vm's or so or less
if your still feeling a bit lazy/hesitant and not putting in the work to make the move away from being well and truely shafted right and proper....
go for it, start the graft, grow some balls... or ovaries :)
a year down the line you'll wonder why u didnt do it sooner and feel "bigger" for it !
dont let the tossers of this world grind u down
