+2. You need to have a Route53 domain configured in the same AWS account and specify the full domain name in **Route 53 hosted DNS domain** configuration (See [Step 11](#route53_config) below). External domain registration is currently not supported. For more information see [What is Amazon Route 53?](https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/Welcome.html).

-- To access the instances, you need to have at least one key pair for SSH keys (**See step 9** in [Configuration settings](#configuration-settings)). For more information see [Amazon EC2 key pairs and Linux instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html).

-- The MLRun software is free of charge, however, there is a cost for the AWS infrastructure services such as EKS, EC2, S3 and ECR. The actual pricing depends on a large set of factors including, for example, the region, the number of EC2 instances, the amount of storage consumed, and the data transfer costs. Other factors include, for example, reserved instance configuration, saving plan, and AWS credits you have associated with your account. It is recommended to use the [AWS pricing calculator](https://calculator.aws) to calculate the expected cost, as well as the [AWS Cost Explorer](https://aws.amazon.com/aws-cost-management/aws-cost-explorer/) to manage the cost, monitor and set-up alerts.
