How is the system deployment carried out on different infrastructure nodes?

Deploying a system across different infrastructure nodes is usually done through automation and orchestration.

Main approaches:

• CI/CD pipelines: automated scripts that build, test, and deploy the application to the required servers.

• Configuration management tools: Ansible, Puppet, Chef allow describing the state of nodes and bringing them to the desired state.

• Containerization and orchestration: Docker for packaging the application and Kubernetes for managing deployment on a cluster of nodes.

• Load balancing and service discovery: ensure the availability and scalability of the application.

Example: using Kubernetes, you can define a Deployment that automatically deploys the required number of application pods on different cluster nodes, ensuring updates without downtime.
