t4g.nano

the T series is more suitable for non-performance-verified test environments

It\'s the same for t4g.

Additionally, t4g is an ARM-based processor, and it may not support some of the programs or scripts that you already have.

Thank you ! Do you know if it\'s optimized for ECS ?

I think the key thing to understand here is that with little to no traffic, it absolutely will not make a difference and thus you should go with the cheapest (in this case t4g) option available.

General purpose workloads with moderate CPU, memory, and network utilization.Save up to 40% over T3 instance pricing

T4g instances feature the same credits system, AWS Nitro System, and Burstable mode as T3 instances.

AWS re:Invent 2020: Reduce cost with Amazon EC2’s next-generation T4g and T3 instance types

Thank you. I was nearly clueless.

Ok. I\'ll check.

Here is a documentation page that you can add to your answer with more details on AMI, included ECS optimized Amazon Linux 2 : docs.aws.amazon.com/fr_fr/AmazonECS/latest/developerguide/… Unfortunately arm64 AMI for Amazon Linux 2 is not available in all regions.

It turns out the RIs were in the Availability Zone, not in the Region, so I was not getting the benefit of size-flexibility. The thing that eventually tipped me off was I bought 8 \"nano\" RIs, and had one nano instance running. My Utilization Report showed 12.5%, so I figured the RIs weren\'t being applied to my larger instances. I changed the RIs to be in the Region, and my Utilization Report immediately improved.

I had an expiring RI for a t4g.large instance, and Amazon recommended I buy (8) t4g.nano RIs. I have since replaced the t4g.large instance with a t4g.medium and t4g.nano instance, thinking I was reducing my overall usage. But now the Cost Explorer is showing my costs have risen over 100%, the RI Utilization Report shows a steep decline, which matches the decline in the RI Coverage Report. Worse, the recommendation engine is now recommending I buy (10) more t4g.nano instances. All my instances are running in the same Availability Zone (us-east-1c). They\'re all t4g instances. They all run Ubuntu. They all have default tenancy (shared). My usage has been steady for the last year. The only change I can see is the RI conversion. I\'m not getting the expected benefit of the nano RIs. What is going on? How do I get these new RIs to cover my usage?

I think the discrepancies can be attributed to the choice of the t-style instances. They are generally over committed.

Aren\'t \'t\' instances burst instances? They need to be under constant load for a long time before their burst credits for CPU, memory, network and EBS run out, after which they fall back on their baseline performance.

It\'s the same for t4g.

So that would mean Unlimited is not a setting available for T4g (ARM instance) and therefore _may_ explain inconsistent behavior in the ARM instance.

The next-generation T4g instances, powered by AWS Graviton2, enable up to 40% higher performance than T3 for times when you need performance as well as 20% lower cost.

Cost Explorer is your best option to review and understand the usage and coverage in order to review your recommendations which would help in a big way! Another thing to note that there is a normalization factor that you need to consider which would match the recommendations. For instance size nano= 0.25 (normalization factor), micro=0.5, small=1, medium=2 and large=4, similarly the rest of them.

In my experience, t4.large offers slightly higher performance than t3.large and is also more cost-effective.

Thank you for this article. We have T instances for EC2 and RDS and we are expecting some very strange performance behavior. Do you have plan to test RDS?

The t3 family is a burstable instance type. If you have an application that needs to run with some basic CPU and memory usage, you can choose t3. It also works well if you have an application that gets used sometimes but not others.
