What can be written in this term paper?

Question

IT education

Hey Habr.
The university asked the following term paper:
"Research on the possibilities of building a computer platform of increased stability for accounting and management accounting of a small business based on virtualization technologies and cluster computing systems."

Who can advise what? So far, I have only such an idea - to take VirtualBox, VmWare and Microsoft Virtual PC in turn in the amount of two guest machines with the same config, install WinServer 2003 and XP on them, and, accordingly, test in speed (what? .. I don’t know myself)
After that, in principle, you can roll MSSQL on Server, on XP - 1C Enterprise, connect and start testing.
By the way, does it even make sense to take 1C into virtualization?

Thanks for answers!

Answer 1

If you want a test bench with virtualization and failover clusters, then you do not have many options (organizing a failover cluster). The biggest difficulty is in the virtualization of a shared disk array (i.e. a disk array with which 2 or more servers can work simultaneously) - SQL Server is not installed in a cluster without it. I know two such ways.
1. Use MS Virtual Server 2005. It has a RAID emulation mode with clustering support. Create a disk on a virtual SCSI controller and, when creating virtual machines, connect an additional disk to the system disk in each of them (it is usually created on an IDE controller).
2. You can use iSCSI technology to create a shared disk array. This option is more difficult, but also more interesting. With software like Starwind iSCSI Target (they have a trial; or you can look for another iSCSI software target vendor) you can create a "virtual" disk array and share it among the failover cluster nodes. In our company, virtual servers are deployed according to this scenario.
If you want details, you can ask.
In any case, you will first have to figure out how to build fault-tolerant storage systems (disk arrays).

Answer 2

if stability is equated with reliability and fault tolerance, then the platform can be driven on RAID

Answer 3

take in turn VirtualBox KVM, VmWare ESXi/XEN and Microsoft Virtual PC Microsoft Hyper-V

fixed.

Answer 4

We can talk about the fact that if all this software runs in the cloud, then we get high fault tolerance.
The collapse of any machine from the iron of the cloud will not be noticeable at all to the end user.
You can consider existing software to create your own cloud and pick up software and hardware.
Or compare the creation of your own cloud with a ready-made one (Amazon). Take into account the specifics of the area (is it possible to store your accounting records in Amazon)

Answer 5

Application server 1C (version 8.1) is virtualized (using VM Ware), the SQL server is clustered, its virtualization is not needed, since in any case all allocated resources will be utilized.
Advantages of virtualization - a separate server is allocated for each database, they are independent (relatively of course) from each other, the installation time of a new server is 15 minutes, the time to change the amount of RAM (if you prove to the admins that it is not enough :)) - one reboot.
In general, after the servers have been virtualized, the system behaves more stable.
