I personally recommend enhancing your IT resources by branching your networks into the ubiquitous “Cloud.”  Your competition is tripping over themselves getting there.

Our Strategic Partner CloudFlare operates through 12 data centers scattered around the world (Singapore, Hong Kong, Tokyo, Los Angeles, San Jose, Dallas, Chicago, New York, Ashburn, Paris, Amsterdam, and Frankfurt). We use Anycast (to listen to the same IP out of multiple locations) as well as GeoIP DNS in order to route a request from a visitor to the website to the nearest data center. In each data center, CloudFlare runs a reverse proxy that does full inspection (down to Layer 7) of each request looking for threat signatures. The data centers also run caching to automatically detect static objects that make up a website and store them closer to the visitor. Requests for objects that are not cached are passed back to the origin server. The original server’s response passes back through CloudFlare’s proxy, which can scan, analyze, and rewrite the content without blocking delivery.

I appreciate the safety-net of security, support, and raw server power, without having to sacrifice any of the legacy enterprise topography or alter the app server configurations.  It promised to increase speed, and it delivers!
