Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Sharing data between 2 servers in different DC's

[Blikje]

Hi,

I would like to know if it is technically possible to share data between 2 servers, each located in different datacenters.
For excample (for a service), the free server stands in DC A, and for the Pro (paid) service the server is in DC B. When a free user wants to upgrade his account to paid, he basically needs to change server. All his account info needs to be send to the server in DC B. This don't needs to be done in realtime, but can have an interval of 1 hour or something like that.

Would that be possible? Is it just a matter of sending data to a specific IP, where the there located script will do the rest of the work (so it is all a matter of programming), or are there more things to consider?

Thank you very much,

Jacco

Just write a script to ftp his data over and set the config up for his site. The only issue you *might* have is a password and you could get them to supply it on upgrade.

Its all relatively simple to do. In a way part of it is the same as a remote backup program. That backs up all your stuff to another server but in this case you want it to reconfig the virtual hosts etc.

Then you need to remove it from the old server, BUT you want to be 100% sure that it has transferred correctly obviously.

thats a super broad question there!

What data? What system? What O/S ? What panel?

The mere transfer of data between 2 systems is simple - this can be done with FTP, or for security some kinda SSH tunnel etc..etc..

User on server a) pays for upgrade. You setup on server B and then transfer his data over. Simple - but requires work from u.

As far as an autonomouse transfer that was linked in with the control panel? I imagine this wuld be quite complex.

Basically it is just database stuff which needs to be transferred, simple info likem customer info and service details. This will be made on server A, and than transferred to server B where the scripts can reads it.
Glad to hear it is just a matter of programming (I am not a programmer myself, therefore I asked it ), thank you for your answers guys!

Depending on the size of your database...

Schedule a cron job on the hour to do a dump of the database. Rsync the two files over ssh. Load the new db info into the "pro" server.

I'm far from a db guru so reloading the db every hour might not be a good idea. There are plenty of "right" ways to do this. This isn't one of them. This is a cheap hack which would probably do what you want.
