Here's a site that compares a few cloud hosts, although I'm not sure how up-to-date it is: http://www.mrkirkland.com/cloud-computing-price-comparison/ I also compared aws pricing to google app engine, and it seems that yes, aws is the cheapest. However, you should also read about the quality of aws hosting before you use it, as I have heard of many issues ...

$10 -- You can't run a website on AWS at this price. The minimal server they offer is a "Micro" instance at $0.02 per hour which is $14.40 per month. Even at slightly over budget you wouldn't want to use a micro instance for a website because the machine is severely limited. It is meant for testing only. As the CPU quota is used up, it may become ...

Amazon IAM ( http://aws.amazon.com/iam/ ) service gives you the ability to create accounts for students with separate password/credentials and with access to only specified AWS resources. You can create one account for all students there, or create a group called "Students" and assign all your students to that group. After doing that you need to specify an ...

AWS is Amazon Web Services. It's the umbrella term that covers a range of (separately priced) web services from Amazon. The best known services are S3 Simple Storage Service, Amazon's "cloud file system" if you like. EC2 Elastic Compute Cloud, their scalable web server service for running your own web apps. SimpleDB, a scalable and simple (non-relational) ...

No, Rackspace doesn't have the equivalent of "stopping" an instance. If you delete the server it's gone, including any local backups. You can, however create an image of the server before you delete it. You can then restore the server later by doing a "Create Server From Image...".

The advantage of CloudFront is that it serves your content geographically near to your users. A dedicated server is only in one location, but enables you to do lots of different things. You can't easily compare the two things.

I'm afraid I couldn't help you with the complications of setting up a Postfix mailserver, however with regards to your questions about the DNS records: The MX record you have created looks fine, provided that you have checked that (a) you have no other MX records with a priority less than 10, and (b) you have definately also got an A record setup for ...

There is also a site which calculates cloud hosting prices from various providers - www.cloudorado.com. You can just check how much would cost a server you need from various providers. Amazon is often not the cheapest unless micro instance is used. Update: Here is also an article which tries to answer exactly the same question.

I wouldn't call this a simple question! The answers to your many questions certainly aren't simple. Load sharing and replication between databases (the two are different) is a complex subject and probably couldn't be answered in a few paragraphs. However, let's see I can shed some light. Yes, multiple instances in setup 1 will work for mainly static ...

Sorry but no, you can't. WordPress is entirely scripted in PHP. If you host a copy of a WordPress installation on a S3 bucket you will be lacking the PHP interpreter and the mySQL engine. The whole deal with EC2 is having a virtual machine so you can run services like a mysql server or a php instance. Anyway, with some elbow grease you could host a static ...

This fellow says here that there is no penalty on Google SEO just for sharing an IP with another site.

At the time this question was asked, this was not something RDS supported. Subsequently, though, AWS announced point-and-click copy of Amazon RDS DB Snapshots across AWS Regions. To launch an instance from a snapshot in a different region, you have to first copy the snapshot from the region where it was created and stored, into the target region. In the ...

If your campaigns are merely controversial you should be fine as it would be exceedingly hard to determine the owner of a S3 account merely from the URL (assuming, of course, you don't do something completely moronic like use your full name for the bucket). You may also want to make sure that neither your username/email address associated with the account ...

There is no secret methodology to be determined here, and no need to do what you are trying to do. You should bid what the machines are worth to you, because you will not pay any more than the market demands. Now, I previously believed Amazon would just charge me for the highest price right above the next lowest competitor automatically ... I'm not sure ...

I think using it with Lightbox makes chance of download hard. You can read this article: How to create a Video Membership Site with Complete Protection to Your Videos and after the content I found this: Limitting Accessing to Video Content These are for Wordpress but I think you can easily apply for PHP or other web programming language. Note : I ...

In my experience, two nameservers are required, and three are sufficient. Four is overkill.

Here are more organized queries against the INFORMATION_SCHEMA Sizes By Storage Engine SELECT IFNULL(B.engine,'Total') "Storage Engine", CONCAT(LPAD(REPLACE(FORMAT(B.DSize/POWER(1024,pw),3),',',''),17,' '),' ', SUBSTR(' KMGTP',pw+1,1),'B') "Data Size", CONCAT(LPAD(REPLACE( FORMAT(B.ISize/POWER(1024,pw),3),',',''),17,' '),' ', SUBSTR(' KMGTP',pw+1,1),'B') ...

show table status from mydatabsename; where mydatabasename is your database name. This shows you the metrics Data_length and Index_length per table and other metrics. You would have to total these columns and remember that they are in bytes so you would have to divide by 1024 to get kb and then by 1024 again to get megs and then by 1024 again to get gigs. ...

From What are the most commonly used and basic Apache htaccess redirects? contributed by bybe: Catch all and redirect non-www to www You should opt to use mod_write for redirecting all requests for non www versions of your site because the $1 varible will catch page names, so example.com/page1/ will automaticly redirect to www.example.com/page1/. ...

You should have your website and your database in the same availability zone. It should be faster You are less exposed to the risk of an availability zone going down. When you spread your web server and database between two, your website goes down if either of them goes down. RDS has an option to have a hot spare of the database running in another ...

We decided to save all xml files zipped to database and get them from there as soon as a bot asks for a specific XML Sitemap. Here are the theoretical steps: Create XML files with 45.000 urls. (45k according to this post) Save every url to database with information in which XML Sitemap it is in. gzip those files (8mb => 400-600kb) save them to a xml file ...

I agree with @bybe. A 301 redirect in your .htaccess file would do the trick. RewriteCond %{HTTP_HOST} ^myapp\.domain\.com RewriteRule ^(.*)$ http://domain.com/myapp/$1 [R=301]

It is possible that some sites that link to you may run regular checks on their outbound links to make sure that they still work; if you block them there is a chance their script will see your link as dead and remove it, hurting your SEO. It is also possible that smaller search engines may use 'the cloud' to gather data, and blocking them would hurt your ...

I have also found myself in this position and wanted to give you my feedback: I've spent hours researching and refining my ip tables to get the best of both worlds, but in reality it's not possible to have any real accuracy and I have decided to take the scraping hit but allow full access to AWS. Like you have stated, AWS is a very popular platform for ...

You can cache the files using cache-headers on the container of your files on the S3. Simply change the TTLS and this will start caching the files: check out Automatically apply HTTP Headers.

It's always best to serve as much content in the same zone that way the hops between servers is much greater. If host both the RDS and EC2 in the same zone/region then the traffic is internal and therefor SUPERFAST. If you host RDS in one Region and EC2 in another then they are having to talk to one another from a much larger distance therefor the response ...

It is going to vary wildly. Mostly, you are going to need to track the maintenance and downtime schedules for two zones, and you'll lose a lot of in-region pricing discounts on bandwidth.

you should use Amazon IAM service http://aws.amazon.com/iam it will allow you to create subaccounts for your students and they will be able to publish they website the same way as you publish with your main account

"Need" is hard to define. Hopefully Amazon will never lose your data, but of course they can't guarantee that. What you could do is back up to a different AWS region so that your backup is on a different continent to your live system.
