What is the recommended instance type for Koha?

For optimal performance, we recommend using an instance type with at least 2 vCPUs and 4 GiB of RAM. Larger libraries may require more resources.

We provide two architecture options for each AMI: x86_64 and ARM64. If you don’t have a specific preference, we recommend choosing the ARM64 AMI. Instances such as the t4g family (which are ARM64-based) typically offer better performance at a lower cost compared to their x86 counterparts.

What does "self-service" mean?

Self-service means you can launch, configure, and start using the Koha Library System on your own, without needing a vendor to do it for you. This way, we keep costs low and Koha affordable for all our clients.

We provide a pre-configured Amazon Machine Image (AMI) on the AWS Marketplace. Once you subscribe, AWS will guide you through launching your own Koha server. Everything is pre-installed — including the database, web server, and Koha itself.

You’ll follow a simple 3-step process:

  1. Subscribe to the AMI on the AWS Marketplace

  2. Launch an EC2 instance using our AMI (this is your Koha server)

  3. Access your server via web browser to finish the Koha setup wizard

It typically takes less than 5 minutes.

🛠️ If you need help at any point, we offer paid support for setup, configuration, domain names, or customization. Contact us via our Professional Services product page on AWS Marketplace. 

What is the backup and recovery process for Koha on AWS?

Koha automatically performs daily backups of your database and configuration, saving them in the folder /var/spool/koha/library on your server. Additionally, you can use the Export Data tool in the Koha console to download backups manually.

To further protect your data, you can store these backups in external storage locations such as Amazon S3, Google Drive, Dropbox, or locally on a USB stick or external hard drive.

Koha on AWS is fully compatible with AWS backup and recovery tools, including AWS Backup. We strongly recommend setting up automated backups to ensure your data is consistently protected and can be easily restored in case of issues.

What are the hardware requirements for running Koha on AWS?

For optimal performance, we recommend using an instance type with at least 2 vCPUs and 4 GiB of RAM. Larger libraries may need more resources. Choose the right instance type based on your library’s needs to ensure a balance of cost and performance.

 

 
How secure is Koha on AWS?

Koha on AWS benefits from AWS's robust security infrastructure, including network isolation, encryption at rest and in transit, and regular security updates. Additionally, you can implement custom security measures, such as VPC configurations, security groups, and IAM roles, to further protect your library’s data.

Billing

How can I convince my administration to adopt Koha?

If you’re a librarian interested in using Koha but need approval from your school, library board, or university administration, here’s a simple strategy that minimizes risk and cost:

  • Start with the Free Tier AMI (coming soon):

    Launch a fully functional Koha server at zero cost using our Free Tier AMI in combination with the AWS Free Tier. This gives your institution up to 12 months of usage without any charges (when using a t2.micro or t3.micro instance).

  • No commitment needed:

    Since there are no upfront costs, you can demonstrate Koha’s features, workflows, and benefits in a live environment before seeking budget approval.

  • Try Standard and Enterprise Editions risk-free:

    Both include a 14-day free trial, allowing you to showcase premium features and performance enhancements at no cost.

  • Build a case with real usage:

    Use this evaluation period to gather feedback, run pilot programs, and compare Koha’s functionality and cost savings against your current system or vendor quotes.

Many institutions are more likely to approve a purchase after seeing a working system in action—especially one that aligns with both their budget and technical needs.

How do I manage my Koha subscription?

You can manage your subscription through the AWS Marketplace console under 'Manage subscriptions'. Here, you can view details and make changes as needed.

 
How much does it cost?

We offer multiple pricing options to suit different needs:

  • Free Tier (coming soon): From $0.00/hour – ideal for small libraries or testing purposes, with some feature and usage limitations. You can run this edition at no cost using AWS Free Tier-eligible instance types like t2.micro or t3.micro, which provide up to 750 hours/month free for 12 months.

  • 14-Day Free Trial: When launching the Standard edition from AWS Marketplace, you get a 14-day trial with full functionality and no limitations — perfect for evaluating a full Koha setup before subscribing.

Are discounts available?

Our pricing is already set as low as possible to ensure maximum value without compromising quality. Other vendors—both open-source and commercial—charge up to $33,000 per library. We keep overhead costs minimal so that libraries of all sizes can access a high-quality, cloud-based Koha system at a fraction of that cost.

While we do not offer additional discounts, you can still reduce your total cost by taking advantage of the following options:

  • Koha Free Tier AMI (coming soon): When combined with the AWS Free Tier, you can run Koha at zero cost for up to 12 months using eligible instance types like t2.micro or t3.micro (up to 750 hours/month).

  • 14-day free trial: Use this to evaluate the Standard and Enterprise (coming soon) Editions before committing to a subscription.

  • Annual billing: Choosing the yearly subscription over the hourly option can save you up to 33% in your first year.

These options ensure you get maximum value from Koha on AWS—whether you're just getting started or ready to scale.

Can I use Koha for both academic and public libraries?

Yes, Koha is versatile and can be used by both academic and public libraries. It offers specific modules and features that cater to the needs of both types of libraries, including circulation management, cataloging, and user access controls.

 
Can I use Koha for a multi-branch library?

Yes, Koha is fully capable of supporting multi-branch libraries. It offers flexible features for managing multiple locations, ensuring that you can maintain seamless operations across all branches.

 

 
Can I use a custom domain with Koha?

Yes, you can configure a static IP for your instance and map it to a custom domain for seamless access to your Koha OPAC and staff client. To do this, you will need to SSH into your Koha server and modify the Apache configuration to respond to your custom domains.

Steps to configure your Koha server for custom domains:

  1. Login to your Koha server via SSH

    Use your SSH client to access your Koha server.

  2. Edit the Koha Apache2 configuration file

    Open the library.conf file in your preferred text editor:

    sudo nano /etc/apache2/sites-available/library.conf
    # or
    sudo vim /etc/apache2/sites-available/library.conf

  3. Modify the virtual host settings for OPAC and Staff pages

    Update the configuration so that it reflects your custom domains for the OPAC and staff client. For example:

    • OPAC (Public) Domain Configuration:

       
      <VirtualHost *:80>
      ...
      ServerName opac.example.com
      ...
      </VirtualHost>

    • Staff (Intranet) Domain Configuration:

       
      <VirtualHost *:80>
      ...
      ServerName staff.example.com
      ...
      </VirtualHost>

    Important Notes:

    • Port 80 should be used for both the OPAC and staff clients (default for HTTP). Previously, port 8080 was used for the staff client, but it is now replaced by port 80.

    • Update the ServerName directive to match your desired URLs, such as opac.example.com for the OPAC page and staff.example.com for the staff interface.

  4. Update Apache Listener Configuration

    Ensure that Apache is listening on the correct ports. Open the port.conf file:

     
    sudo nano /etc/apache2/ports.conf
    # or
    sudo vim /etc/apache2/ports.conf

    • Remove any reference to port 8080 and ensure Apache is only listening on port 80:

       
      Listen 80

  5. Restart Apache to apply changes

    After making these changes, restart Apache to ensure the new configuration is applied:

     
    sudo systemctl restart apache2

By following these steps, you’ll configure your Koha server to use custom domains for both the OPAC and staff interfaces, all running over the standard HTTP port (80). This improves accessibility and simplifies the user experience.

 
Can I customize the look and feel of the OPAC (Online Public Access Catalog)?

Yes, Koha allows you to customize the OPAC to match your library’s branding. You can modify themes, templates, and even implement custom features to tailor the OPAC to your needs.

 

 
Can I configure Koha to work with other library systems?

Yes, Koha supports interoperability with many library systems and third-party applications through industry-standard protocols like MARC 21, UNIMARC, Z39.50, and SRU/SW. If you need to integrate Koha with another system, we can help you configure and customize the setup to meet your needs.
