AWS EC2 T4g Instance experience?

So I dont know if this is the right categorie - I thought fits best in devops since there is no cloud computing categorie.

My usecase:
I have a bunch of microservices and most of the time nothing/very little happens but sometimes traffic and cpu load 10x - 100x

Also I found no documentation on the network credit system i guess its the same as the cpu credit system but I dont know

So the t4g instance fits the bill but I just want to know if I’m missing something and or what the experience of other people is with t4g

Also i know its arm

You might be able to use a smaller instance in combination with Elastic Beanstalk.

I was looking at 30x t4g.micro and I’m not fermiliar with Elastic Beanstalk
