The Weka cluster on Azure provides a fast and scalable platform to run, for example, performance-intensive applications and hybrid cloud workflows. It can also be used for object stores, tiering, and snapshots using the Azure Blob service. The provided Azure-Weka Terraform package contains modules and examples you can customize according to your deployment needs. The installation is based on applying the customized Terraform variables file to a predefined Azure subscription. Applying the Terraform variables file performs the following:
- Creates resources in a predefined resource group, such as virtual machines, network interfaces, function app, load balancer, and more.
- Deploys Azure virtual machines.
- Installs the Weka software.
- Configures the Weka cluster.
