This deployment strategy enhances safety by allowing thorough testing before promoting new versions to production. Implementing blue-green deployments can be done manually using Kubernetes Services or through tools like Argo Rollouts and Flux CD. Although beneficial in terms of safety and rollback capabilities, the approach can be resource-intensive and costly. Alternatives such as canary or rolling updates may be more suitable depending on specific requirements. ## Full article daily.dev links to this article rather than hosting it.
