What is an Amazon EC2 Compute Unit

Amazon offers different types of Instance types for their customers to meet their cloud computing needs. Each instance has different specifications and customers can choose any instance type based on their need. Now, when you look at the specifications of each instance type, you should find a term called “EC2 Compute Unit”. This is one thing that confused me for a while. I made a Google search for the term and found some relevant information that explained things. So, in this article, I will try to explain you what an Amazon EC2 Compute Unit really means.

In simple terms, Amazon EC2 Compute Unit determines the speed of the processor. The more the value the higher you have the cpu power. The screen shot below shows the value of CPU speed in one of our virtual machines created with KVM Virtualization software.

The official amazon documents talks little bit more about ec2 compute unit here.

Now, being said that having one or more virtual cores with one or more EC2 Compute Units doesn’t always mean that you get all the virtual cores for your machine. I work at a data center where we have a similar kind of virtualization environment. The the physical processor we use has two cores with two threads allocated for each core. So, on the whole, I get 4 virtual cores to create a virtual machine. Generally, I create as many as 10 different virtual machines allocating all the available virtual cores to all the virtual machines. This setup runs perfectly fine with out any problem unless until some virtual machines consume whole lot of resources.

I really don’t know how amazon allocates virtual cores from the real processor. All I know is that a single virtual core can be distributed to many number of virtual machines created from a single virtulization server.

I hope this article helped you understand what Amazon EC2 Compute Unit really mean. If you have any questions or suggestions do leave your comment right here.
