T3: Rise of the Burstable Machines

If Skynet was to need some ad-hoc computing power, it'd probably use AWS' new T3 instance

On August 21st, AWS launched the third incarnation of the widely-used "T" instance family of burstable, general purpose compute types. They aren't quite self-aware, but they do offer some pretty cool features over the previous generations.

Upgraded compute power

The lower-end T3 instance types have all received double the compute power, with vCPUs and CPU credits being raised to 2 and 6 respectively. The higher-end types have their CPU capacities kept pretty much static, with the exception of xlarges and 2xlarges, which see decent increases in CPU credits.

There are also increases to the T3's baseline performance percentages: the amount of access to the underlying CPU's (2.5 GHz Intel® Xeon® Skylakes) hyperthread processing power.

Cost Saving

T3s are around 90% of the cost of the equivalent T2 types, based on OnDemand pricing for Linux instances in London.

Burstable Network and Storage

All new T3 instances are powered by AWS' Nitro system (see: The Nitro Project: Next-Generation EC2 Infrastructure). Nitro, as well as being a super cool architecture, adds network bursts up to 5 Gbps and EBS bursts (including IOPS) of between 1.5 Gbps and 2.05 Gbps.

Burstable instances are ideal if you are running choppy workloads that don't regularly consume large amounts of compute power, but have high CPU usage spikes. T3's will accumulate CPU credits that can be used to burst as and when required.

You can spin up T3 instances today in any of these regions: US East (Ohio), US East (N. Virginia), US West (N. California), US West (Oregon), Canada (Central), Europe (Ireland), Europe (London), Europe (Frankfurt), South America (São Paulo), Asia Pacific (Tokyo), Asia Pacific (Singapore), and Asia Pacific (Sydney).

Hasta la vista, baby!
