POCan someone elaborate on these basic concepts of hosting via Amazon Web Services?

Body
copied!<p>I read all over the Amazon documentations, but I'm still confused or should I say overwhelmed by the different terms. </p> <p>I'm coming from a traditional web hosting environment where the only concept I understand is how much storage I have and how much bandwidth I'm allowed. </p> <p>Here are what I understand so far about amazon and my questions about a lot of it. </p> <p><strong>EC2</strong> - I assume are instances where I can set up my webserver (IIS) and run my .NET application? Or is it already setup for me?</p> <p><strong>EBS</strong> - For database? If not, where do I get the database server? Is the database server (Sql server 2005 or 2008) already installed? What is Snapshot Get Requests? and Snapshot Put Request?</p> <p><strong>S3</strong> - What is this used for? I thought EBS is for storage, confused here. Why you need S3?</p> <p><strong>Elastic Load Balancing</strong> - I thought load balancing is just a way to alleviate the burdens on your web servers. how does it work with Amazon? What do they mean by "elastic" load balancing?</p> <p><strong>Data Transfer between region</strong> - What does that mean? and how do you control which region the data transfers to and from?</p> <p><strong>My requirements are the following</strong></p> <ol> <li>I need an IIS webserver to run my page</li> <li>I need a database server</li> <li>I need a location to store my files (can it be on the same "server" as #1)?</li> <li>I need the database and file servers to always be recoverable. (I heard we need to store it into EBS to avoid loss of data?)</li> <li>In case one web server is overloaded, performs slow, I need it to switch off to another server in the farm. </li> <li>If traffic spikes, then I need a way to increase CPU, memory, etc. The ability to handle traffic nicely (which is the purpose of elastic I'm assuming)</li> </ol> <p>In addition, I don't really understand the concept of "if you are not running your instance, shut it down or else it will be charged". I will run a website which ideally is to keep it up 24/7. In what scenarios do you conditionally have the instances up or down? </p> <p>[Edit]</p> <p>And how do you exactly monitor your usage? So you don't get surprised with a couple thousands of dollars? can you put a cap on it? I read stories where AWS users got surprised by a $300 bill or whatever when they didn't have much hosted on Amazon nor have any traffic intensive sites. </p> <p>Sorry, I'm a complete newbie to "cloud" computing. Trying to catch up here. </p> <p>Thanks a lot in advance</p>
