High Scalability Building bigger, faster, more reliable websites.

You want to have a scalable website. You want a website which can handle traffic spikes (think if you are getting on Digg, Slahsdot, Reddit, Techcrunch or other very popular websites frontpage).

Regular hosting companies (especially shared hosting) can offer only so much. The servers usually get crushed under the load in short time.

But there is hope. A new breed of hosting companies emerged recently. A new breed which can offer you the scalability you need at a fraction of the cost.

Welcome to the world of “cloud computing!” (or “grid computing” or “utility computing”, which are terms for the same thing).

Here's a website which compiled a list of cloud computing hosting companies (with short descriptions, prices and customer lists for each of them).

Scalr is a fully redundant, self-curing and self-scaling hosting environment utilizing Amazon's EC2. It has been recently open sourced on Google Code.

Scalr allows you to create server farms through a web-based interface using prebuilt AMI's for load balancers (pound or nginx), app servers (apache, others), databases (mysql master-slave, others), and a generic AMI to build on top of.
Scalr promises automatic high-availability and scaling for developers by health and load monitoring.

The health of the farm is continuously monitored and maintained. When the Load Average on a type of node goes above a configurable threshold a new node is inserted into the farm to spread the load and the cluster is reconfigured. When a node crashes a new machine of that type is inserted into the farm to replace it.
