What is blue-green deployment and how is it monitored?

Blue-green deployment is a strategy for application deployment that reduces downtime and risk by running two identical environments, called 'blue' and 'green'. Monitoring involves tracking performance metrics and user traffic to ensure a smooth transition.

What tools can I use to monitor blue-green deployments?

You can use tools like Prometheus, Grafana, and New Relic to monitor your blue-green deployments effectively.

How do I roll back if something goes wrong?

If an issue arises, you can quickly switch traffic back to the previous environment (e.g., from green back to blue) to minimize impact.

Are there any best practices for implementing blue-green deployment?

Yes, best practices include automating the deployment process, ensuring thorough testing in the green environment, and monitoring user feedback closely.
