- Magento 2 deploy strategies aim to deploy more frequently with less downtime and reduced costs through consistent, developer-friendly processes. - Challenges include continuous improvement, resilience, ease of use, training, and integration with tools like Slack and Magemojo. - Example code provided automates the deployment process through commands like composer install and cache flushing. - Tools like Deployer and Magedeploy.sh help standardize local development and deployment through recipes that support features like zero downtime deployment and rollback. - Continuous delivery tools like GitHub Actions integrate deployment into existing workflows while deployment tools separate these concerns for more flexibility.
