What are the main differences between using Docker Compose and orchestration with Docker Swarm?

Main differences between Docker Compose and Docker Swarm:

• Docker Compose is a tool for defining and running multi-container applications on a single host. It allows describing services, networks, and volumes in a YAML file (docker-compose.yml) and starting them with a single command.

• Docker Swarm is an orchestration mechanism built into Docker, which enables managing a cluster of multiple Docker hosts, providing scaling, load balancing, and fault tolerance.

Key differences:

Feature	Docker Compose	Docker Swarm
Scaling	Local, on a single host	Clustered, across multiple hosts
Load balancing	No	Yes, distributes requests among nodes
Fault tolerance	No	Yes, automatically restarts containers on failures
Usage	Development and testing	Production and scalable environments

Example: for local development, Docker Compose is convenient, while for deploying an application in production with multiple servers, Docker Swarm is suitable.
