# Minimum Requirements | Official Documentation

> Review system requirements including OS, CPU, memory, and dependencies to ensure a successful and stable deployment.

# Minimum Hardware Requirements

OpenMetadata requires either MySQL or PostgreSQL as Backend Database and ElasticSearch or OpenSearch as Search Engine.

Please refer to the [architecture section](/v1.12.x/developers/architecture) for more details.

We recommend the following for the Production Grade OpenMetadata Installation -

## MySQL or PostgreSQL as Database

Our minimum specs recommendation for MySQL / PostgreSQL as database deployment is

* 4 vCPUs
* 16 GiB Memory
* Storage:
  * **Minimum**: 100 GB
  * **Recommended**: 150–200 GB (depending on workload)

<Note>
  For enterprise use cases with heavy workloads, we recommend 150–200 GB of storage to accommodate larger datasets and transaction volumes.
</Note>

These settings apply as well when using managed instances, such as AWS RDS or GCP CloudSQL or Azure Flexible Servers.

### Software Requirements

OpenMetadata currently supports -

* MySQL version 8.0.0 or higher
* PostgreSQL version 12.0 or higher

## ElasticSearch or OpenSearch as Search Instance

Our minimum specs recommendation for ElasticSearch / OpenSearch deployment is

* 2 vCPUs
* 8 GiB Memory
* 100 GiB Storage (per node)
* Master / Worker Nodes with atleast 1 Master and 2 Worker Nodes

### Software Requirements

OpenMetadata currently supports -

* ElasticSearch version 9.x (minimum 9.0.0, recommended 9.3.0)
* OpenSearch version 3.x (minimum 3.0.0, recommended 3.3.0)

These settings apply as well when using managed instances, such as AWS OpenSearch Service or Elastic Cloud on GCP, AWS, Azure.

## Apache Airflow as Ingestion Instance

Our minimum specs recommendation for Apache Airflow is

* 4 vCPU
* 16 GiB Memory
* 100 GiB Storage for Airflow Dags and Logs

### Software Requirements

OpenMetadata currently supports -

* Airflow version 2.10.5
