Answer: A complex TOSCA template for a multi-tier application might consist of web servers, application servers, and database servers. Each component is represented as a TOSCA Node Type, and relationships are defined between them. The template outlines deployment details, configurations, and scaling rules for each tier, creating a comprehensive blueprint for the application’s structure and behaviour.

Question: You are given a TOSCA service template for a web application. The template defines a web server and a database server as two node types. Explain how you would deploy this application using a TOSCA orchestrator.

Answer: To deploy the web application using a TOSCA orchestrator, you’d follow these steps:

  • Define the target cloud environment and provider.
  • Instantiate the node types in the template, specifying the desired instance details.
  • Define any relationships between the web server and the database server.
  • Specify the network configuration, such as IP addresses and ports.
  • Set up policies and constraints for auto-scaling or high availability, if needed.
  • Validate the service template to ensure it’s free of errors.
  • Execute the deployment with the TOSCA orchestrator, which will provision the necessary resources and configure the application according to the template.

This deployment process ensures that the web application is provisioned and configured correctly in the target cloud environment as defined in the TOSCA service template.
