	Burstable instances such as the t2 instances have CPU credits. ~~VMs accumulate~~ a certain amount of credit every hour~~, depending~~ on ~~the instance type and uses~~ credits ~~when consuming more CPU than some threshold~~.		Burstable instances such as the t2 or t3 instances have CPU credits. Any CPU usage on the instance will use credits (at 1 credit per CPU/minute). Depending on the instance type, an instance will accrue a certain amount of credit every hour. Accounting is performed at a millisecond resolution.

			More information can be found on AWS's documentation: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-credits-baseline-concepts.html

			: An entire dedicate host is reserved.

			When looking at pricing for a particular VM, keep in mind that you must pay for:
			# Compute time (eg. $0.001/hr for spot instances, or $0.01/hr for on-demand)
			# Storage (EBS at $0.11/GB/mo or more for higher IO)
			# Bandwidth ($0.09/GB)

			The minimum amount of storage each VM running Linux can be created with is 8GB.

	~~There are many different instance types. The 12 month free eligible type is t2.micro which comes with 1 vCPU, 1GB RAM, 15GB Outbound Bandwidth. The value of the t2.micro VM in US East (Ohio):~~
	* $0.01 per hour * 720 hours/month ($7.20)
	* $0.1 per GB/mo storage * 30 GB ($3)
	* $0.09 per GB/mo bandwidth * 15 GB per month ($1.35 - $0.09 as 1st GB is free)

			In comparison, a t3a.nano using spot pricing costs about $4/mo:
			* $0.0016 per hour * 720 hours/month ($1.15)
			* $0.1 per GB/mo storage * 30 GB ($3)

			Looking at just the pricing, AWS EC2 is actually very expensive for what you get. Others have mentioned alternatives including:
			* Vultr
			* DigitalOcean
			* Linode
			* OVH

			If a VM to run some workload is all you need, some low end VPS packages from WHT offers are also valued very well.
