Pricing

A free license is provided for this distribution including the fundamental part of the extremum platform. It covers the platform core and basic components that provide query processing, data operations, execution of user functions, and distribution of event signals.

The license for the extremum.pro 3.1 distribution kit components included in the extremum.farm system package is commercial. It is provided for each installation of a solution developed based on the platform. Pricing is based on the current discount program for early installations of the extremum.pro 3.1 release:

The discount program is valid until August 31, 2023. After that, new installations of extremum.pro 3.1 will be charged based on new terms and conditions.

1. Create a service account with the admin role.

2. Create a Kubernetes cluster. Under Service account for resources and Service account for nodes, specify the service account created in step 1.

3. Create a node group for the cluster. Minimum computing resource requirements:

   • vCPU: 2.
   • Guaranteed vCPU share: 50% or more.
   • RAM: 8 GB.

4. On the extremum.pro 3.1 page in Yandex Cloud Marketplace, click Deploy in cluster and select the previously created cluster.

5. On the application setup page, specify the parameters:

   • Administrator password: Enter the password to the application.
   • Service account SSH key: Paste the generated SSH key or generate a new one.
   • (Optional) API web domain: Your own web domain for your application based on extremum (make sure it is delegated to the ns1.yandexcloud.net and ns2.yandexcloud.net servers). If you do not specify your own domain, the <service _account_id>.y.e6m.io domain is created.

   The platform will be fully deployed and ready for use within 20 minutes.

Wait for the extremum application’s status to change to Deployed, and for the pods in the Workload tab to have the Running status (except for deploy-instance and deploy-common, for each of which the only condition is the Succeeded status for at least one pod). If you get any error messages regarding the cancel debugging information, just ignore them.

To start using the platform:

1. In the management console, select the folder with the cluster where extremum.pro 3.1 is hosted.
2. Select Object Storage.
3. Select the e6m-<deployment_id> bucket.
4. Open the readme.html file in the bucket. It contains data about operations with your platform instance (deployment_id, service URLs, and more).
