That is good news.
T2 instances CPU credits is really great feature introduced 2 months ago for EC2. Amazon RDS Now Supports T2 Instances
At the same time the price for T2 RDS instances is twice less then for the previous generation.
T2.micro EC2 + T2.micro RDS are good if you are thinking about web app which will have the “scheduled” workload. E.g. the main customers are from the particular region.
While the instance is IDLE it accumulate CPU credits. And you servers will be able to burst above the baseline as needed. You can track your CPU Credits trough AWS Console. It is really fun to track them
On the image below one of my EC2 instance has 150 CPU Credits. This means that it will be able to rocket up to the “cloud” if needed. But still you pay for micro instance. CPU Credits really brilliant idea from Amazon!
