c1.medium

While the chart above is a good start, there’s more than simply considering “Reserved vs. On Demand”. So let’s take a closer look at all the options…

Bandwidth is tiered by instance size, here's a comprehensive answer:

Almost everything in EC2 is multi-tenant. What the network performance indicates is what priority you will have compared with other instances sharing the same infrastructure. If you need a guaranteed level of bandwidth, then EC2 will likely not work well for you.

FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.

I have been a fan of `c1.medium` for years, but there does not appear to be any reason to use it any more. I’m [moving mine](https://alestic.com/2011/02/ec2-change-type) to `c3.large`.

I cannot find exact network performance details for different EC2 instance types on Amazon. Instead, they are only saying: * High * Moderate * Low What does this even mean? I especially want to know the exact amount of `Traffic-OUT` on each instance type. I need to do live streaming and my stream bit rate will be 240kbps. So I need to know which instance type can handle how many concurrent viewers.

We run on multiple c1.medium instances that are auto-scaled with a m1.db.small RDS instance, cache.t1.micro ElastiCache server for full page caching and CloudFront CDN served from two S3 sources.

EC2 instances are priced according to instance type, regardless of the number of CPUs enabled. Disabling vCPUs does not change the cost of the instance type.
