I am seriously impressed with Amazon’s cloud offering. You get a pick list of virtual machines of different sizes, a CDN, monitoring with elastic forking of new instances, fixed IPs if required, S3, attachable storage and the ability to release software as .amis for easy deployment, map-reduce with Hadoop, load balancing and a payment service.… Continue reading Ehcache Server in the Cloud

Me:decoded

Me:decoded I recently had my DNA tested by deCODEme.com.  My wife thought I was crazy.
