Subject Re: When to use AWS SQS?
Date Mon, 19 Aug 2013 14:22:24 GMT
Hi,  

I think you should know the difference between the IAAS and SAAS[1].

When you using EC2, you don't need to take care of the physical machine any more, but you
still need to install the OS, DB and Application Server to build up your service.
But if you are using AWS SQS, you don't need take care of the physical machine, Broker, or
DB, you just need to use SQS API to access the service that you want.  
And AWS SQS will solve the HA, scalability issue for you.
