I just need some guidance on locating a good hosting solution for one of our customers application. They expect us to manage their infrastructure any way, so I'm looking for better options.
Possible options would be;
1. Own the hardware and collocate the relevant systems
2. Hosting with Rackspace or Softlayer
3. Host with a Cloud provider, Amazon ?
About the application; (PHP/PostgreSQL)
1. Main purpose of this application is Media upload/download and streaming
2. 8000 active use base and 3000 concurrent will be expected during the peak time
3. Geographically 90% from Australia, New Zealand and the rest will from United Kingdom and South Asia
4. They expect about 25,000 to 40,000 users during next 3 years
I need your valued comments on this, also I'm thinking how I can manage the security if we decided to host this with a Cloud provider, any recommendation guidance and support would be highly appreciated.
Thanks a lot for your time !
