Deploy to Vespa Cloud

How to host a Vespa application on the cloud

Open In Colab

Install pyvespa

pip install pyvespa

Define application package

This tutorial assumes that a Vespa application package was defined and stored in the variable app_package. To illustrate this tutorial, we will use a basic question answering app from our gallery.

from import QuestionAnswering

app_package = QuestionAnswering()

Setup your Vespa Cloud account

  1. Sign-in or sign-up: To deploy app_package on Vespa Cloud, you need to login into your account first. You can create one and give it a try for free.
  2. Choose a tenant: You either create a new tenant or use an existing one. That will be the TENANT_NAME env variable in the example below.
  3. Get your user key: Once you are on your chosen tenant dashboard, you can generate and download a user key under the key tab. Set the USER_KEY env variable to be the path to the downloaded user key.
  4. Create a new application under your tenant: Within the tenant dashboard, you can also create a new application associated with that tenant and set the ` APPLICATION_NAME` env variable below to the name of the application.

Create a VespaCloud instance

from vespa.deployment import VespaCloud

vespa_cloud = VespaCloud(

Deploy to the Cloud

We can have multiple instances of the same application, we can then chose a valid INSTANCE_NAME to identify the instance created here and set the DISK_FOLDER to a local path to hold deployment related files such as certifications and Vespa config files.

app = vespa_cloud.deploy(
    instance=os.getenv("INSTANCE_NAME"), disk_folder=os.getenv("DISK_FOLDER")

That is it, you can now interact with your deployed application through the app instance.
