Hi experts;
I am new to iWAN, can someone tell me why  is it beneficial? We have mostly 1 WAN and 1 router connected MPLS  sites in the network, can we still make use of it?

Basically, it lets you centralize control of remote site routers and specify how traffic flows from remote sites to your central sites and/or the internet.  You'll need to check your hardware models and firmware levels for compatibility,

This blog explains it nicely:

And here is a PDF brief from Cisco:

I do not think I made myself very clear, the question that I had is as per the scenario below:

1. There are sites which are on MPLS network running on 3900/2900 series Cisco gear, mostly single connected via 10M/T1 links.
2. There are sites which are linked via VPN tunnels to Data Centers via internet connections.
3. If we convert the internet connected sites to iWAN sites, (of course with ISR 4K routers), will the above setup work seamless in mixed

Please let me know  if there are any pitfalls/deficiencies etc.

Thanks in advance;

iWAN would help in those scenarios If you plan on letting the ermote sites access the internet directly instead of routing all traffic back to your central office.  If all traffic (including internal bound and external bound) is going to go back to the central office, then there is not much for iWAN to do.

The main caveat of iWAN is that you'll be locked into a pricey Cisco proprietary solution.  So when the licensing costs increase, you're only options are to pay them or drop it develop a new solution.

I believe it is an annual renewal, but you'll have to check with your Cisco reseller.
