I really have no idea about costs. I need to figure this out as part
of a budgeting exercise, and compare against Linode

Linode are priced differently. EC2 is based on usage, where as Linonde
is more or less a fixed cost per month. I have DHIS2 running on both
at the moment, in order to compare the differences between the two in
terms of performance and costs.

I guess the obvious advantage is scalability. I am using the Amazon
RDS as a backend, so I guess that scaling the front-end and backend is
going to be possible. It is pretty simple to scale Linode as well, and
the pricing is a lot more transparent, but I am not sure in terms of
how it will perform or scale when compared to EC2.

I think an EC2 micro instance is for the most part free, so it is easy
to get started experimenting. This is what i chose for this image. You
can also install MySQL/Postgres on the instance and not use the RDS
backend.  The RDS service costs, but it seems to be very unclear how
much it costs. Perhaps after a month's usage or so, I would be able to
provide more details.

Another issue is how to scale this app. Multiple small instances which
are load balanced against each other, or bigger instances? I have
essentially no experience with this stuff ,so it would be good to get
others feedback.

Let me clean the AMI up a bit and i can provide details.

Regards,
Jason
