November 14, 2025 - Providing tenancy type as “host” is optional while launching instances using AWS License Manager. Yes, in order to launch an instance while using AWS License Manager, you need to attach a host resource group to your license configuration in AWS License Manager and set up license rules so that new instances are launched as per your capacity requirements. A host resource group is a group of Dedicated Hosts that you can manage as a single entity.

you are locking down a single piece of hardware just for your purposes.
Dedicated Instance does not work like this. Your instance runs on some dedicated hardware. Its not lockdown to you. If you stop/start instance, you can get some other hardware somewhere else. Basically, the hardware is "yours" (you are not sharing it with others) for the time your instance is running. You stop/start it, you may get different physical machine later on (maybe older, maybe newer, maybe its specs will be a bit different), and so on. So your instance is moved around on different physical servers - whichever is not occupied by others at the time.
With Dedicated Host the physical server is basically yours. It does not change, it's always the same physical machine for as long as you are paying.

Dedicated Host
As soon as you 'allocate' a Dedicated Host, you start paying for that whole host.
A host computer is very big. In fact, it is the size of the largest instance of the selected family, but can be divided-up into smaller instances of the same family. ("You can run any number of instances up to the core capacity associated with the host.")
Any instances that run on that Host are not charged, since you are already being billed for the Host.
That is why a Dedicated Host is more expensive than a Dedicated Instance -- the charge is for the whole host.
Dedicated Instance
"Dedicated Instances are Amazon EC2 instances that run in a virtual private cloud (VPC) on hardware that's dedicated to a single customer... Dedicated Instances may share hardware with other instances from the same AWS account that are not Dedicated Instances."
This means that no other AWS Account will run an instance on the same Host, but other instances (both dedicated and non-dedicated) from the same AWS Account might run on the same Host.
Billing is per-instance, with a cost approximately 10% more than the normal instance charge (but no extra charge if it is the largest instance in the family, since it requires the whole host anyway).

r/aws on Reddit: Dedicated hosts Vs dedicated instances
September 25, 2020 -
Hi guys are dedicated hosts basically an entire physical server rack that customers can select and can choose which individual physical server in rack that the instances can be deployed on ? Is dedicated instances basically instances that are running on the same physical server on a shared rack ? Each time a dedicated instance is stopped started , it goes onto a new physical server which only the company can spin up new vms ?

When you launch a dedicated instance, the EC2 service looks for an actual physical server (hardware) in the data center that currently has no EC2 instances (VMs) running on it, and spins up your instance on that. If you launch additional dedicated instances after the first one, the service is likely to bring those up on that same hardware. However, there are no guarantees that will happen, and you don't get to make that choice. The way that dedicated hosts (hosts now, not instances) works is that when you choose to run your instances on dedicated hosts, the EC2 service API returns a Host ID, which is for a physical host (server hardware) that AWS is setting aside for your exclusive use. Of course, they start billing you at that point. When you launch an EC2 instance, you now have the option of passing that Host ID as a parameter, which will ensure that the new instance comes up on that host, assuming there is available capacity for running an instance of the requested size. Dedicated instances guarantees that your EC2 instance will be running on hardware that's not shared with another AWS customer. Dedicated hosts also does this, but lets you specify the host, once it's been set aside for your exclusive use. I believe that you need to keep at least one instance running on a dedicated host in order to prevent AWS from returning that hardware to general use/On Demand status.
