Dimensions summary
You pay by the hour for the software on each running EC2 instance. Pricing follows the AWS EC2 instance type you choose, so there are no tiers or plans to compare. The rate scales with the size and family of the instance. Compute-optimized (c-family), storage (d, i, h families), graphics/accelerated (g, f, p families), memory-optimized (r, x, z families), and general-purpose (m, t families) instances each carry their own hourly rate. Larger sizes within a family cost more per hour. You run the same Debian-based image regardless of which instance you select.
Top-of-mind questions for buyers
You get a Debian-based Linux base image built for EC2. It includes the latest stable kernel, pre-installed Ruby and Python runtimes, and core system utilities. Cloud Ops Group delivers ongoing security and performance updates. The same image runs on every instance type you pick.
The hourly software rate meters running time on each active instance. A stopped instance does not accrue the software charge. You may still pay separate AWS fees for attached EBS storage while the instance is stopped, since backups and storage are your responsibility.
Domain registration and DNS are not included. Email delivery must be configured separately. Managed backups are your responsibility, so plan for snapshots or AWS Backup. SSL/TLS is not set up by default; place the instance behind a load balancer or content delivery service.
