Help for a question - Networking

[upul1986]

In your university you are asked to come up with a social network to be used for internal communication. Using your experience of programming languages, scripting, web designing and database systems you come up with a proposal for a small scale social network using RDBMS. Your design utilizes only 2 servers (one works all the time whilst the other is idle). After going through a few evaluations you realize you've missed the most important non-functional requirement of a social network i.e. 'Scalability' What are the changes you will be making? (Hint: Think of the Network architecture and the properties of the DB you have to consider)

Thanks

As you are having two servers, its a waste that keeping one in idle. If the simultaneous requests for the server becomes high in time to time. It may fail to response such high number of requests and may become unresponsive.

So as a solution we can use both servers to handle requests simultaneously so that higher scales of server load will be shared by both servers and resource usage will also be efficient. Still the back pan will be active, as one server goes down other server will still be there as a backup plan.

The database can also be derived in same way.

Thank you very much for giving me a helping hand as soon as possible. I understand that we can utilize both servers to balance the load and we can preserve the backup plan as well. Is there a specific reason for using RDBMS for social networking projects?

Thanks again.

I am not sure about this answer.

RDBMS supports multi server hosting (Load balanced) of databases in parallel servers. RDBMS is having parallel query functions to facilitate this. So if its a social networking we will have to use RDBMS.
