Hi All

i am doing OCMJEA part 2 and require some help on deployment diagram.

Can anybody help me for the below questions on deployment diagram

I dont know much about capacity planning I have never done that. But in my deployment diagram i have to provide hardware profile. So how to decide which hardware should be used to fullfill NFR.?

2) the NFR i have to point are performance(3 sec response time), scalibility, availability(99.99%) and security. In the assignment the only thing given no. of users -100000 and with in one year its going to be 100% incresed.

3) I have used 1 load balancer and firewall, 3 web servers(2 working + 1 hot stand by), 3 app server(2 working + 1 hot standby), 3 database server(2 working + 1 hot stand by). but i am not sure how to get hardware profile. means

which app server, webserver etc i have to use?
how much RAM?
which OS?
how much HDD, no of processors?

Please provide some inputs or some example(links) on this.

Thanks

One way to think about this is whether your performance requirements are below or above average. Then you can look at the servers being sold and scale accordingly.
