I created an aws account a year ago. And I reserved a t2.small instance for 1 year. Now I want to switch to t2.micro and I was wondering if I am still eligible for free tier? During the previous year I was also using ESB 30gib under the free tier.
Yes, your free tier is over. The free tier is up to 1 year from the date of your AWS account creation
Even AWS do let you know whenever you are about to launch any Instance whether is it in the free tire or not.
