Ok, a few basic questions. What's the workload? What portion of the db access is read vs write? What portions of write traffic is US west vs other locations?
You also mentioned file access time - could you describe that problem a bit more? Basically, if you've got a reasonably normal CMS, much of the traffic is read. You've already got asiapac datacenter space, so some replication techniques may be able to get big wins. Mysql slaves, prepositioning files via sync or CDN, some global load balancing tricks... Cloud won't help- you've already got 2 sites, and aren't utilizing them. You'll need to look at these techs with the cloud, you might as well start there...
