How Much Does It Cost to Deploy PostgreSQL?

The cost of deploying PostgreSQL can vary widely based on several factors, including the hosting environment, licensing, support and maintenance, and additional necessities such as development and administration, and backup solutions.

Hosting Environment

Deploying PostgreSQL can be done in different environments, each with its own cost considerations:

On-Premises

For those choosing an on-premises deployment, initial setup costs can range from a few thousand to hundreds of thousands of dollars, depending on the scale. Costs include hardware (power, cooling, and maintenance) and the infrastructure required to manage the database. These costs can be significantly high for large-scale applications.

Cloud

Cloud services such as AWS RDS, Google Cloud SQL, and Azure Database for PostgreSQL offer different pricing models based on instance type, storage, and I/O operations. Monthly costs can range from $15 to several thousand dollars, depending on the configuration. For example, a small instance might cost around $100 per month, while a dedicated instance can cost upwards of $1000 per month. Storage for 100 GB SSD can cost around $20 per month, and backup storage can cost around $10 per month.

Licensing

PostgreSQL is open source and free to use, so there are no licensing fees. However, if you opt for managed services from third parties like Crunchy Data or EnterpriseDB, additional fees may apply. Support contracts can vary in cost, ranging from a few hundred to several thousand dollars annually.

Support and Maintenance

Hiring professional support, such as from Crunchy Data or EnterpriseDB, can add additional costs. The costs of support contracts can vary widely, but they typically range from a few hundred to several thousand dollars annually.

Development and Administration

Deploying PostgreSQL also requires skillful developers and database administrators. Salaries for these roles can vary significantly based on location and expertise. For example, a junior developer or administrator might earn around $50,000 per year in a competitive market, while a seasoned professional could earn up to $150,000 per year.

Backup and Disaster Recovery

Implementing backup solutions or disaster recovery plans, especially for cloud storage or third-party services, can incur additional costs. For instance, a third-party backup solution might cost around $10 per month, and cloud backup storage can range anywhere from $10 to $50 per month depending on the storage requirements.

Example Cost Breakdown for a Cloud Deployment

Instance Type: $100/month for a small instance Storage: $20/month for 100 GB SSD Backup Storage: $10/month Support (if applicable): $500/year Total Estimated Monthly Cost: $130 excluding support, which would be approximately $42/month if spread out over the year (based on a support contract of $500/year).

Conclusion

The overall cost of deploying PostgreSQL can range from very low for small, self-managed instances to significant amounts for large enterprise-level deployments. Evaluation of specific needs and choosing the appropriate setup is crucial to manage costs effectively.

When deciding on the hosting environment, consider your existing infrastructure setup. If you already have servers, the cost is zero as the software itself is free. You can opt to host the database on third-party vendors to get peace of mind that you're in capable hands. If you're running your project in a cloud provider's infrastructure, check if they offer PostgreSQL as part of their database services. Both Google Cloud and AWS offer managed database services that include PostgreSQL.
