NOTE: **Optional:** Instead of storing configuration _and_ repository data on the root volume, you can also choose to add an additional EBS volume for repository storage. Follow the same guidance as above. See the [Amazon EBS pricing](https://aws.amazon.com/ebs/pricing/). We do not recommend using EFS as it may negatively impact GitLab’s performance. You can review the [relevant documentation](../../administration/high_availability/nfs.md#avoid-using-awss-elastic-file-system-efs) for more details.
Now that we have our EC2 instance ready, follow the [documentation to install GitLab and set up Gitaly on its own server](../../administration/gitaly/index.md#running-gitaly-on-its-own-server). Perform the client setup steps from that document on the [GitLab instance we created](#install-gitlab) above.
