We are designing a new IT-infrastructure and I would like to hear your input on ideas and suggestions to create the best design possible. Look forward to a constructive dialogue.
Background info thats relevant:
- One headquarter with 70 users on the network. This network has 100 mbit Internet connection and gigabit network. Users have local standard PCs with I5/8GB/128SSD computers - Windows 10 in-place included in a 2012R2 AD.
- Two remote offices with 5 + 7 users. These offices are connected to the HQ over VPN and have the same PC standard.
- All offices have 1-2 printers on the LAN.
- We use O365 for Exchange Online at the moment only.
Now we are designing an upgrade where we need to solve these needs:
- There is a client / server ERP system there the PCs will get a client installed that works with a server (with DB installed). All users on all sites need to be able to reach this ERP system. It is heavy and requires good LAN performance and stability.
- All PCs need MS Office that we plan to procure thru Office 365 Business Premium for all local PCs.
- About 30 users need to be able to work from home with all systems, incl ERP. So we plan some RDP/RemoteAPP solution.
- There needs to be ONE central File share for all common documents (they dont want and cannot use Sharepoint).
- The ERP, Mail, Document functions may stand still a max of 2 hours if problems occur, and they can only allow approx 15 mins of dataloss during working hours. So backups need to run incrementally every 15-30 mins.
Our ideas we would like to have your opinions on/and ideas about:
1) Install a primary hyper-v 2012 Core host at the HQ. With 8xSAS 15krpm drives in RAID10 config, 10GbE nic, dual CPUs/64 GB RAM.
2) Install a secondary hyper-v host with exactly same specs and run Hyper-V replication of VMs using 10GbE so we are safe if the primary host fails.
3) Install 2 AD Domain Controller VMs, One ERP server VM, 2 2012R2 RDS VMs with RDP and RemoteApp. RDP would be for all users at the remote sites as this would work for ERP, MS Office and Files. All users that want to work from home with either home computer or laptop (if they get one) can use Remote App Website / RemoteApp to launch ERP client and/or RDP desktop remotely.
4) For all users that need local MS Office use Office 365 Business Premium and for all that are supposed to work remotely over RDS servers get Office 365 E3 which allows RDS installation.
5) Establish a VPN tunnel to Azure and run a DC also there for backup.
6) Backup from the hyper-v host to a local NAS for VM backups using Veeam B&R. Then also replicate these VMs to the cloud (Azure?) for daily offsite data protection.
Could be more things we have not thought of, please feel fre to ask and comment on our ideas 1-6. Perhaps you see some totally simpler way, cheaper etc. We dont think we can run all in Azure as this 1) Would cost more 2) Risk if ISP fails.
Thanks and appreciate your help,
