What would be the best way to achieve these kind of specs over proxmox.
This means, The configurations will be VPses, but there will be a deicated server, or some dedicated servers which will make the other configurations possible
General specifications
High availability setup in all parts to prevent SPOF
High performance DB cluster with redundancy
Optional 2 data centers for disaster recovery with synchronization in between
Optional monitoring server for internal workflows and health monitoring
Optional testing machine for SSO testing purposes
Optional connection to other solution (hybrid setup)
Hardware specifications per data center
2x Webserver node (8 cores, 64GB RAM, disk system 60GB)
2x application node (8 cores, 48GB RAM, disk system 60GB)
3x database node (4cores, 64GB RAM, disk system 60GB, disk data SSD 240GB)
2x database load balancer (2 cores, 4GB RAM, disk system 60GB)
2x filesystem storage node (up to 100TB of usable space, available over NFS3, ex: 32cores,
512GB ram, disk system 60GB, disk l2arc cache SSD 2-4T, 7.200+rpm HDDs 20TB)
2x WebDocuments node (8 cores, 32 GB RAM, disk system 80GB)
1x testing server (2 cores, 4GB RAM, disk system 60GB)
1x monitoring server (2 cores, 4GB RAM, disk system 80GB)
Itās easier to try to set it up on a local server, than a hosted vps, at least if youāre doing it for the first time!
You can try as often as you want, until youāre satisfied itās working as you want, and if not, you know how to fix itā¦
You canāt route IPs which donāt ābelongā to you.
IPs belong to a provider, unless you are registered with RIPE, ARIN, AFRINIC, APNIC or LACNIC.
Providers among each others do NOT use routing like normal, they use AS (Autonomous System) Routing, often BGP (Border Gateway Protocoll). If you have an AS Number, basically you CAN do real Internet Routing.
See here:
and here:
A unique ASN is allocated to each AS for use in BGP routing. ASNs are important because the ASN uniquely identifies each network on the Internet. ā¦
AFAIK, in Europe you need at least a full class C Network to get an AS Number, besides certain requirements in schooling and costsā¦
Otherwise youāre just renting an IP from your Provider.
Sure you can rent a car at AVIS, but you canāt return it to a Hertz dealer!
You can ask your Home Provider for more IP Adresses.
You can use internal routing to make services appear as coming from your hosted environment (eg Reverse Proxy) , but you reduce your network by 50% with this (All traffic provided to the Internet from your Home pases twice through the Hosting Provider), and itās not the most stable and best solution. But would be possibleā¦
Routing would not be possible - simple because TCP/IP wouldnāt allow it.
Port forwarding would work, over a VPN, with a 1:1 NAT (Not the usual 1:Many NAT).
Or Reverse proxying. Or a combination of both.
Getting a second or small block of IPs (4-8 IPs ?) from your Home Provider would be much more stable and technically better!
What you CAN use at home is Name based virtual hosting, all on the same IP. That would NOT work for certain things, like separating VoIP for 2 or more clients. But a lot of Web based stuff would work.
Try asking your Home Provider first, how much would a small block of IPs cost (say 4, 8 or even more IPs, depending on what you need for the moment.)
Then youāld know if your traffic migration plan āsavesā money, or cost more in terms of money and headachesā¦
If I knew exactly what you wanted connected, and where, I could plan it out for you. But if the IPs are ācheapā (Always relativ), then Iād go that routeā¦
Or just get yourself Pritunl, create a big global network connecting all your servers (Home & Hosted) and you can route almost anything anywhere internally, or use front ends for the internet, the back-ends being at homeā¦ Around 600.- a yearā¦
But constantly the VW is automatically migrated to Node 1. Even after a manual migration to Node 3, a migration back to Node 1 starts immediately.
After a manual migration to Node 2, however, this back migration does not take place automatically.
Why is it not possible to leave the VM located on Node 3?
Best regards, Marko
Addendum 1: I notice the same behavior when I manually migrate the VM-102 located on node 2 to node 3. Immediately an automatic migration to Node 1 starts.
If I then start a manual migration to Node 2, VM-102 remains there without the automatic migration to Node 1.
