If you had a chance to read my getting started with Ec2 article I highlighted some of the challenges with deploying applications on the cloud. One of these challenges can now be easily overcome based on a new feature recently provided on Ec2

Elastic IP Addresses:
Elastic IP Addresses are static IP addresses designed for dynamic cloud computing, and now make it easy to host web sites, web services and other online applications in Amazon EC2. Elastic IP addresses are associated with your AWS account, not with your instances, and can be programmatically mapped to any of your instances. This allows you to easily recover from instance and other failures while presenting your users with a static IP address.

Availability Zones:
Availability Zones give you the ability to easily and inexpensively operate a highly available internet application. Each Amazon EC2 Availability Zone is a distinct location that is engineered to be insulated from failures in other Availability Zones. Previously, only very large companies had the scale to be able to distribute an application across multiple locations, but now it is as easy as changing a parameter in an API call. You can choose to run your application across multiple Availability Zones to be prepared for unexpected events such as power failures or network connectivity issues, or you can place instances in the same Availability Zone to take advantage of free data transfer and the lowest latency communication.

Every new addition makes Ec2 more attractive. In the coming months I will be experimenting more with deploying a large scale application to the cloud and will post some of my findings.


David Kernell is the 20-year-old son of Tennessee’s Democratic Representative Mike Kernell, and David got caught red-handed. Based on the CNN account “Democratic lawmaker's son indicted in Palin hacking,” David reset the password of GOP vice presidential hopeful Sarah Palin’s personal e-mail account. David allegedly read the contents, took screenshots, and got a hold of other private information. Some of the information believed to be compromised includes Palin’s address book, photos of family and friends, contact phone numbers, and family birthdates among other things. Ironically, although David Kernell turned himself in, he pled not guilty. Why would he plead not guilty after he took the information he hacked from Palin’s personal account and posted it to a public website? Not only did David post Palin’s personal information to the public site, but he posted the new password he created, which made it possible for others to access and view Palin’s e-mail account. As a consequence, David Kernell could serve five years in jail, pay a $250,000 fine, and be subject to three years of supervised release. At the maximum of $1,500 per loan, that fine would require approximately 167 individual payday loans to free himself from the confines of prison Post Courtesy of Personal Money Store Professional Blogging Team Feed Back: 1-866-641-3406 Home: http://personalmoneystore.com/NoFaxPaydayLoans.html Blog: http://personalmoneystore.com/moneyblog/
