Hi Steve and list,
I guess it depends on your usage. AWS group their instance types into
"families", and if memory is more important to you than any other
resource, perhaps the "Memory-Optimized" family is what you are
looking for.
If you have different intents in the application (for example, you need
a lot of ram for task-driven threads, but not much for session-driven
threads) you could deploy your application to two or more clusters/vms
to fit their different resource needs.
With respect to cost: There are a number of ways to possibly keep costs
down. You only pay for the hours your vm is running, so if it suits your
business you can always schedule the entire EC2 to be shutdown for part
of the day/week. (You could use a simple AWS Lambda for this!) If you
can utilise Spot Instances in your workflow they are very accommodating.
Keep track of your compute and other services and it shouldn't get out
of control. Monitoring your apps and the usage of EC2 is your friend :)
Regards,
