While as much of the GitLab application as possible runs in Kubernetes or on AWS services (PaaS), the GitLab service Gitaly must still be run on Ec2. Gitaly is a layer designed to overcome limitations of the Git binaries in a horizontally scaled architecture. You can read more here about why Gitaly was built and why the limitations of Git mean that it must currently run on instance compute in [Git Characteristics That Make Horizontal Scaling
