Some generally questions

hello All,

i found opennebula from an Linkedin post and i really like it. but before i read now hours over hours to fit my requirements i just ask here.

what we have: multiple networks with 12x28er subnets. each network (172.16.x.x) are one customer (customer doesnt have access to the environment) what i need is a all in one solution: on each customer runs UCS Servers (5x), Windows Servers (3x) linux rocky (2x) and some dockers. i jucked some readmes but i can not see clearly if all requirements are met; here are the requirements:

  1. need run VMs and dockers, templates (as i understand, and i likc it much: are there customerization for values in the template form: does it work for windows as well ?)
  2. does every customre need an own oneks or can 1 oneks run all container for all customers with adding them to the right subnet ?
  3. every customer can be isolated (no access outside the own network in and out allowed, only 3 server can communicate to outside (2 of them for a public service)
  4. oneks is only with the enterprise edition available - correct ?
  5. opennebula is perfect for HCI with ceph, i read it
  6. it can be easily extented to an offsite datacenter ?
  7. what kind of backup is available and 100% compatible (with dedup, compression, single files and whole image restore) ?

this should be the most important question in my mind to figure out if the product is really an addon for us. thx for answer

regards

Hello! Let me check:

  • UCS is based in debian and provides a KVM image. Installing the OpenNebula contextualization package on it would give you some more configuration options from it.
  • OpenNebula contextualization works on Windows, Rocky linux (I prefer Alma, but Rocky works as well). Please take into account that Windows contextualization may lack some of the
  • The dockers should be running in a VM living in OpenNebula, unless you run something like GitHub - linka-cloud/d2vm: Build Virtual Machine Image from Dockerfile or Docker image · GitHub that would convert it directly to a KVM image. Note that the contextualization would not be simple to fix, though.
  • That is up to the administrator. Kubernetes can be treated as a service (a subset of resources managed by OpenNebula).
  • Currently yes, oneks is only available for Enterprise edition customers, as well as the support for Veam (that would the the answer for the point 7.)
  • Yes, but please think that the definition of “commodity hardware” on ceph must be taken with a grain of salt. It is recommended to have servers with plenty of disks (the more OSDs, the best) and memory to take care of it, CPU as well if you are running erasure codes. Also the networking is important in this case.
  • It should be easy as far as there is SSH connectivity between the frontend and the hosts, yes. But please, take into account that there are virtual network related needs.

Cheers!
