 Q:

When should an EC2 instance use "Amazon instance store-backed"?

What are the benefits over using Amazon instance store-backed over EBS block storage? The only thing I can see from the comparison of the two is that instance store-backed seems to incur less charges. 
I will be deploying multiple instances of the same web service that needs very little storage space, but the lack of AMI tools for instance store-backed is putting me off.

A:

There are some advantages and disadvantages to EBS and instance store.  In general, I recommend instance store over EBS for most scalable applications.  
Some advantages of EBS:

Ability to stop/start instances
Root volume size larger than 10 GB
Ease of creating AMIs
Ability to snapshot root volume

Some advantages of instance store:

Not dependent on EBS service, which has had some high profile outages over the past few years
No cost for root volume when instance is running
One less moving part to worry about

There are definitely more advantages and disadvantages than I have listed, but those are the ones that come to mind quickly.  At work, we use instance store for all instances unless there's a very specific reason for having an EBS instance.  All EBS instances are duplicated in every available availability zone within a region to help ensure some instances continue running in the event of another EBS outage.
I like to draw the line at customization: if an instance needs a lot of custom work to function, then use EBS, but if not, use instance store.  I define custom work as tasks that need to be done by hand and are not automated.  We use Puppet to deploy instances from scratch using the stock Ubuntu AMIs.  I wrote a blog post about how we are able to take generic AMIs and place them in service without user intervention.  
If you're going to use AutoScaling or similar technology, I highly recommend investing in automation, even if you will roll your own AMI, as there will likely be changes you'll need between AMI builds (code deployments, etc).
Regarding building instance store AMIs, there are a large number of tutorials available online showing how to build instance store AMIs, as instance store has been around a few years longer than EBS.  The AMI tools are available at http

  Q: 

 When should an EC2 instance use " Amazon instance storehouse - back "? 

 What are the benefits over use Amazon example store - backed over EBS auction block memory? The only thing I can see from the comparison of the two is that instance storehouse - backed seems to receive less charges. 
 I will be deploying multiple case of the same web military service that needs very little storage quad, but the lack of AMI tools for instance store - back is putting me off.

All EBS case are duplicated in every available availability zone within a region to avail ensure some instances continue running in the consequence of another EBS outage. 
 I like to draw the line at customization: if an instance needs a batch of custom employment to function, then practice EBS, but if not, use instance storehouse.   I define custom oeuvre as tasks that want to be done by hand and are not automated.   We use Puppet to deploy instances from scratch using the stock Ubuntu AMIs.   I wrote a web log post about how we are able to take generic AMIs and identify them in service without user intervention.  
 If you're going to use AutoScaling or similar technology, I highly commend investing in automation, even if you will roll your own AMI, as there will likely be changes you'll need between AMI builds (code deployments, etc).
