EC2 instances- Elastic Compute Cloud, this is essentially a virtual machine

In a typical data center, you use a hypervisor like vmware to create virutal machines on top of a physical server and you have a level of liberty to choose your own configuration like vCPU (virtual CPU) and RAM, in cloud , like AWS, its all pre configured! and there comes the AWS Instance families

Instance families :

General Purpose - ATM (a1, t2-t3 families with cpu burst, m5(intel)-m5a (amd) - m6g (graviton)

Compute: c5 -intel, c5a -amd, c6g graviton

Memory : R5, x1, z1

Accelerated Computing -: Gx, Px, INF1, F

Storage: Ix, Dx, Hx

fixed vs burstable:
Cx,Rx, Mx are fixed, static unit based ec2
Tx - CPU burstable - governed by CPU Credits. ex t3 nano has 2vpu and 6 cpu units burstable

Once you spin up server using any of those, it will be in any one of the below states

Instance state
