Anyone used Amazon? May I know what I need to make 120 GB storage and if they recommend the best way in amazon. Plan to do clusterring in Amazon. Any idea abt approx cost. Is it cheaper that Rackspace.

What kind of application are you going to be clustering? LAMP/WISA? What kind of latency is acceptable to you between each instance in your app? The reason I ask is that Amazon's infrastructure is built in a way where clustered applications are not integrated with each other. Instead of being on the same Cloud, let alone possibly the same LAN, you may have pieces of your application in other Data Center's. Just as if you were building a traditional infrastructure the latency in that kind of environment could drastically slow down your application. If this is acceptable to you and your application needs then Amazon may work just fine for you, but some technologies are much better built for Clustering. I have yet to see anything better than the 3tera AppLogic platform for this.

Thanks for the help. I will be clustering LAMP/Asterisk. I fear when an server instance dies the application shouldnt go down. Thats why I look to clusteriring. The database side also I would need suggestions. How S3 clsuter can be done in Amazon. Looking to have two 120GB databases in amazon S3. But dont know hopw clustewring will work between them. S3 seems to be a storage rather than a live server. So could u help me how I can cluster two 120GB S3 together at Amazon.

Does it mean there is no point in doing clustering in Amazon?

S3 is storage, you are correct. EC2 is their computing platform so you need several services from them. Asterisk is highly sensitive to latency and I would be very careful clustering Asterisk through them. If you are set on using Amazon, I would recommend talking to them directly in how to setup what you are looking to do. Any good provider will provide you with good support to earn your business and help you set things up in the best way possible with their company.

It can be done.. but for highly latent sensitive applications such as Asterisk, your QoS will be poor. Amazon's infrastructure was not built with this high level of integrated clustering in mind.

Support must also be a paid service with Amazon. I will be testing to see how it works there? Is there any cloud provider you recommend with reasonable prices and good support?

Even their pre-sales support? Really?

This isn't quite right - when you instantiate a new server instance with EC2, you specify the datacenter you want the system to be in. You *can* have servers in different geographical locations, but that's under the user's control... John

It still may not be in the same Data Center as they have several in the same regions, and even if it is it usually is on a different Cloud and network segment as their services are built out on different infrastructures entirely.

This appears to be true especially related to dns clusterring. I have heard dns clusterring set in Amazon gets interfered with the Amazon technology dns setup in the Amazon's infrastructure

Interesting. The network segment makes sense, I'll have to research a little more on the multiple datacenter part...when I've seen benchmarks in the past for AWS sites I presumed it was one large site. John
