Amazon is increasing the size of T2 instances with the release of t2.large.
Originally released last summer, T2 instances give a baseline capacity and ability to automatically and transparently scale up to full-core processing power on an as-needed basis. This bursting model is based on "CPU Credits" which accumulate during quiet periods for spending during busy periods.
The addition of t2.large instance will bring double the amount of memory and a higher baseline of CPU power.
The options that are available include t2.micro which has a baseline performance of 10%, uses one vCPU, one RAM (GiB), six CPU Credits an hour and costs per hour (Linux) $0.0013 and $9.50 a month.
These numbers are then doubled up through t2.small and t2.medium. T2.large runs 2vCPUs, 60% baseline performance, eight RAM (GiB) and costs 36 CPU credits an hour, the price per hour (Linux) is $0.104 and $76 per month.
Jeff Barr, Chief Evangelist, AWS, wrote: "Many AWS customers are running development environments, small databases, application servers, and web servers on their T2 instances. These applications generally don’t need the full CPU very often, but they do need to burst to higher CPU performance from time to time."
