Akamai transparently mirrors content (usually media objects such as audio, graphics, animation, video) stored on customer servers. Though the domain name is the same, the IP address points to an Akamai server rather than the customer's server. In addition to image caching, Akamai provides services which accelerate dynamic and personalized content, J2EE-compliant applications, and streaming media.

TGL delivers Virtual Private Datacenters and virtual private servers from grids of commodity servers. Each TGL grid consists of a pool of HP servers connected with a Gigabit backbone network and running 3Tera's AppLogic grid operating system. With a Virtual Private Datacenter, you get complete control of your own private grid. Using our visual interface, you set up and assemble disposable virtual infrastructure, including firewalls, load balancers, web servers, database servers, NAS boxes, etc. visually, by pointing and clicking. You can build advanced clusters, deploy large and small applications, and save them as templates that can be provisioned in minutes. You can even build your own virtual servers and appliances.
Can you really create an infinitely scalable infrastructure for less than $100 using Amazon's storage, grid, and queuing services platform? It appears so, at least for the right application. Amazon beams a spot light on the future battle of the roll-your-own versus the connect-the-dots approach to building next generation websites using core external services. Their argument is strong. Using Amazon's platform you can quickly build an infrastructure that would otherwise take an eternity to make, a pile of money to create, and an unbounded mass of people to implement and maintain. Yet Amazon doesn't provide SLAs, so you can you really trust them with your crown jewels? Facebook recently leap frogged Amazon's vision with an even more comprehensive set of services. The battle for the future is on. Site: http://aws.amazon.com/
Why use external services?
Amazon ECS (E-Commerce Service)
Amazon S3 (simple storage service)
Amazon SQS (simple queuing service)
Amazon EC2 (grid service)

Very complete detailed log analysis of activity from every visitor to your web site is only a mouse-click away. In other words, analyze your web logs like never before! It's easy to track sessions, hits, page views, downloads, or whatever metric is most important to each user. You can look at referring pages and see which search engines and keywords were used to bring visitors to the site. Web site behavior, from the top entry and exit pages, to the paths that users follow, can be analyzed. You can learn which countries your visitors come from, and which operating systems and browsers they use. You'll learn how your bandwidth is being used, and how much time users spend on your site. You can tell how popular your files, images, directories, and queries are.
