This is pretty cool, we have 5 (small) instances for OnMyList right now, the database instance could DEFINITELY size up to large or extra large. 🙂
The Amazon EC2 team just added Large and Extra Large instance types to EC2. The former “one size fits all” instance type is now known as a Small instance.
Large instances are 4 times larger in each dimension (CPU power, RAM, and disk storage) than the Small instances and cost $0.40 per hour. Extra Large instances are 8 times larger in each dimension and cost $0.80 per hour.
Both of the new instance types support 64-bit computing. While the Large Instance type offers 7.5 GB RAM, the Extra Large Instance Type offers 15 GB RAM (compared to the Small instance type and its 1.7 GB RAM).
