GitLab "Cloud Native Hybrid" is a hybrid of the cloud native technology Kubernetes (EKS) and EC2. 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 Difficult](https://gitlab.com/gitlab-org/gitaly/-/blob/master/doc/DESIGN.md#git-characteristics-that-make-horizontal-scaling-difficult).

\*Cost calculations for actual implementations are a rough guideline with the following considerations:
- Actual choices about instance types should be based on GPT testing of your configuration.
- The first year of actual usage will reveal potential savings due to lower than expected usage, especially for ramping migrations where the full loading takes months, so be careful not to commit to savings plans too early or for too long.
- The cost estimates assume full scale of the Kubernetes cluster nodes 24 x 7 x 365. Savings due to 'idling scale-in' are not considered because they are highly dependent on the usage patterns of the specific implementation.
- Costs such as GitLab Runners, data egress and storage costs are not included as they are very dependent on the configuration of a specific implementation and on development behaviors (for example, frequency of committing or frequency of builds).
- These estimates will change over time as GitLab tests and optimizes compute choices.
## Available Infrastructure as Code for GitLab Cloud Native Hybrid
The [AWS Quick Start for GitLab Cloud Native Hybrid on EKS](https://aws-quickstart.github.io/quickstart-eks-gitlab/) is developed by AWS, GitLab, and the community that contributes to AWS Quick Starts, whether directly to the GitLab Quick Start or to the underlying Quick Start dependencies GitLab inherits (for example, EKS Quick Start).
This automation is in **Developer Preview**. GitLab is working with AWS on resolving [the outstanding issues](https://github.com/aws-quickstart/quickstart-eks-gitlab/issues?q=is%3Aissue+is%3Aopen+%5BHL%5D) before it is fully released. You can subscribe to this issue to be notified of progress and release announcements: [AWS Quick Start for GitLab Cloud Native Hybrid on EKS Status: DEVELOPER PREVIEW](https://gitlab.com/gitlab-com/alliances/aws/public-tracker/-/issues/11).<br><br>
The developer preview deploys Aurora PostgreSQL, but the release version will deploy Amazon RDS PostgreSQL due to [known issues](https://gitlab.com/gitlab-com/alliances/aws/public-tracker/-/issues?label_name%5B%5D=AWS+Known+Issue) with Aurora. All performance testing results will also be redone after this change has been made.
The [GitLab Environment Toolkit (GET)](https://gitlab.com/gitlab-org/gitlab-environment-toolkit/-/tree/main) is an effort made by GitLab to create a multi-cloud, multi-GitLab (Omnibus + Cloud Native Hybrid) toolkit to provision GitLab. GET is developed by GitLab developers and is open to community contributions.
It is helpful to review the [GitLab Environment Toolkit (GET) Issues](https://gitlab.com/gitlab-org/gitlab-environment-toolkit/-/issues) to understand if any of them may affect your provisioning plans.

While GitLab Reference Architectures generally encourage three zone redundancy, AWS Quick Starts and AWS Well Architected consider two zone redundancy as AWS Well Architected. Individual implementations should weigh the costs of two and three zone configurations against their own high availability requirements for a final configuration.
Gitaly Cluster uses a consistency voting system to implement strong consistency between synchronized nodes. Regardless of the number of availability zones implemented, there will always need to be a minimum of three Gitaly and three Praefect nodes in the cluster to avoid voting stalemates cause by an even number of nodes.
A set of performance testing instructions have been abbreviated for testing a GitLab instance prepared using the AWS Quick Start for GitLab Cloud Native Hybrid on EKS. They assume zero familiarity with GitLab Performance Tool. They can be accessed here: [Performance Testing an Instance Prepared using AWS Quick Start for GitLab Cloud Native Hybrid on EKS](https://gitlab.com/guided-explorations/aws/implementation-patterns/getting-started-gitlab-aws-quick-start/-/wikis/Easy-Performance-Testing-for-AWS-Quick-Start-for-GitLab-CNH).
- The Quick Start creates public load balancer IPs, so that you can easily configure your local hosts file to get to the GUI for GitLab when deploying tests. However, you may need to manually alter this if public load balancers are not part of your provisioning plan. We are planning to make non-public load balancers a configuration option issue link: [Short Term: Documentation and/or Automation for private GitLab instance with no internet Ingress](https://github.com/aws-quickstart/quickstart-eks-gitlab/issues/55)
- It is challenging to get the Quick Start template to load in GovCloud from the Standard Quick Start URL, so the generic ones are provided here:
- [Launch for New VPC in us-gov-east-1](https://us-gov-east-1.console.amazonaws-us-gov.com/cloudformation/home?region=us-gov-east-1#/stacks/quickcreate?templateUrl=https://aws-quickstart.s3.us-east-1.amazonaws.com/quickstart-eks-gitlab/templates/gitlab-entry-new-vpc.template.yaml&stackName=Gitlab-for-EKS-New-VPC)
- [Launch for New VPC in us-gov-west-1](https://us-gov-west-1.console.amazonaws-us-gov.com/cloudformation/home?region=us-gov-west-1#/stacks/quickcreate?templateUrl=https://aws-quickstart.s3.us-east-1.amazonaws.com/quickstart-eks-gitlab/templates/gitlab-entry-new-vpc.template.yaml&stackName=Gitlab-for-EKS-New-VPC)
## AWS PaaS qualified for all GitLab implementations
For both Omnibus GitLab or Cloud Native Hybrid implementations, the following GitLab Service roles can be performed by AWS Services (PaaS). Any PaaS solutions that require preconfigured sizing based on the scale of your instance will also be listed in the per-instance size Bill of Materials lists. Those PaaS that do not require specific sizing, are not repeated in the BOM lists (for example, AWS Certification Manager).
These services have been tested with GitLab.
Some services, such as log aggregation, outbound email are not specified by GitLab, but where provided are noted.

NOTE:
On Demand pricing is used in this table for comparisons, but should not be used for budgeting nor purchasing AWS resources for a GitLab production instance. Do not use these tables to calculate actual monthly or yearly price estimates, instead use the AWS Calculator links in the "GitLab on AWS Compute" table above and customize it with your desired savings plan.
**BOM Total:** = Bill of Materials Total - this is what you use when building this configuration
**Ref Arch Raw Total:** = The totals if the configuration was built on regular VMs with no PaaS services. Configuring on pure VMs generally requires additional VMs for cluster management activities.
**Idle Configuration (Scaled-In)** = can be used to scale-in during time of low demand and/or for warm standby Geo instances. Requires configuration, testing and management of EKS autoscaling to meet your internal requirements.
| Service | Ref Arch Raw (Full Scaled) | AWS BOM<br/>(Directly Usable in AWS Quick Start) | Example Full Scaled Cost<br/>(On Demand, US East) |
Other combinations of node type and quantity can be used to meet the Grand Total. Due to the cpu and memory requirements of pods, hosts that are overly small may have significant unused capacity.
NOTE:
If EKS node autoscaling is employed, it is likely that your average loading will run lower than this, especially during non-working hours and weekends.

Elastic Auto Scale GPT Test Results start with an idle scaled cluster and then start the standard GPT test to determine if the EKS Auto Scaler performs well enough to keep up with performance test demands. In general this is substantially harder ramping than the scaling required when the ramping is driven my normal production workloads.
Deploy Now links leverage the AWS Quick Start automation and only prepopulate the number of instances and instance types for the Quick Start based on the Bill of Materials below. You must provide appropriate input for all other parameters by following the guidance in the [Quick Start documentation's Deployment steps](https://aws-quickstart.github.io/quickstart-eks-gitlab/#_deployment_steps) section.
