Detailed explanation-1: -T2 instances are available to use in the AWS Free Tier, which includes 750 hours of Linux and Windows t2. micro instances each month for one year for new AWS customers.
Detailed explanation-2: -The t2. micro instance is in the general purpose family with 1 vCPUs, 1.0 GiB of memory and low to moderate network performance starting at $0.0116 per hour.
Detailed explanation-3: -A customer with access to the AWS Free Tier can use up to 750 instance hours each of t2. micro instances running Linux and Windows. Usage of the Linux and Windows t2. micro instances are counted independently.
Detailed explanation-4: -A t2. micro instance runs at 100% CPU for the first hour, then has an average of 5% load for the rest of the day. It earns 144 CPU credits in a 24-hour period. It burns 60 CPU credits in the first hour, then 3 CPU credits for each of the remaining 23 hours. Total 129 credits burned.
Detailed explanation-5: -For example, a t2. micro instance has a CPU credit balance limit of 144 earned credits. If it is launched and remains idle for 24 hours, its CPU credit balance reaches 174 (30 launch credits + 144 earned credits), which is over the limit.
