# Reference architecture: up to 1,000 users **(CORE ONLY)**
|
|
|
|
This page describes GitLab reference architecture for up to 1,000 users. For a
|
|
full list of reference architectures, see
|
|
[Available reference architectures](index.md#available-reference-architectures).
|
|
|
|
If you need to serve up to 1,000 users and you don't have strict availability
|
|
requirements, a single-node solution with
|
|
[frequent backups](index.md#automated-backups) is appropriate for
|
|
many organizations .
|
|
|
|
> - **Supported users (approximate):** 1,000
|
|
> - **High Availability:** No
|
|
|
|
| Users | Configuration | GCP | AWS | Azure |
|
|
|--------------|-------------------------|----------------|-----------------|----------------|
|
|
| Up to 500 | 4 vCPU, 3.6GB memory | n1-highcpu-4 | c5.xlarge | F4s v2 |
|
|
| Up to 1,000 | 8 vCPU, 7.2GB memory | n1-highcpu-8 | c5.2xlarge | F8s v2 |
|
|
|
|
The Google Cloud Platform (GCP) architectures were built and tested using the
|
|
[Intel Xeon E5 v3 (Haswell)](https://cloud.google.com/compute/docs/cpu-platforms)
|
|
CPU platform. On different hardware you may find that adjustments, either lower
|
|
or higher, are required for your CPU or node counts. For more information, see
|
|
our [Sysbench](https://github.com/akopytov/sysbench)-based
|
|
[CPU benchmark](https://gitlab.com/gitlab-org/quality/performance/-/wikis/Reference-Architectures/GCP-CPU-Benchmarks).
|
|
|
|
In addition to the stated configurations, we recommend having at least 2GB of
|
|
swap on your server, even if you currently have enough available memory. Having
|
|
swap will help reduce the chance of errors occurring if your available memory
|
|
changes. We also recommend configuring the kernel's swappiness setting to a
|
|
lower value (such as `10`) to make the most of your memory, while still having
|
|
the swap available when needed.
|
|
|
|
## Setup instructions
|
|
|
|
For this default reference architecture, to install GitLab use the standard
|
|
[installation instructions](../../install/README.md).
|
|
|
|
NOTE: **Note:**
|
|
You can also optionally configure GitLab to use an
|
|
[external PostgreSQL service](../postgresql/external.md) or an
|
|
[external object storage service](../high_availability/object_storage.md) for
|
|
added performance and reliability at a reduced complexity cost.
