What is a blue/green deployment?
A blue/green deployment is a deployment strategy in which you create two separate, but identical environments. One environment (blue) is running the current application version and one environment (green) is running the new application version.
What is the blue and green environment model?
This model uses two similar production environments (blue and green) to release software updates. The blue environment runs the existing software version, while the green environment runs the new version. Only one environment is live at any time, receiving all production traffic.
Which AWS Deployment Services support blue/green deployment strategies?
A number of AWS deployment services support blue/green deployment strategies including Elastic Beanstalk, OpsWorks, CloudFormation, CodeDeploy, and Amazon ECS. Refer to Blue/Green Deployments on AWS for more details and strategies for implementing blue/green deployment processes for your application.
What are the disadvantages of a blue-green deployment?
Note: If your app uses a relational database, blue-green deployment can lead to discrepancies between your Green and Blue databases during an update. To maximize data integrity, configure a single database for backward and forward compatibility.
What is the blue-green deployment pattern safe?
Blue green deployment is an application release model that gradually transfers user traffic from a previous version of an app or microservice to a nearly identical new release—both of which are running in production.
What is blue-green deployment CodeDeploy?
The blue/green deployment type uses the blue/green deployment model controlled by CodeDeploy. This deployment type enables you to verify a new deployment of a service before sending production traffic to it.
What is blue-green deployment in Azure?
A blue-green deployment is a deployment strategy where you create two separate and identical environments but only one is live at any time. This strategy is used to increase availability and reduce downtime by switching between the blue/green environments.
What is blue-green deployment vs rolling?
Rolling deployments follow a staggered delivery pattern that gradually replaces instances of the existing environment with updated versions. Meanwhile, blue-green deployments involve creating a rigorously-tested second environment before completely shifting the current instance to the new environment.
What is blue green deployment in AWS?
A blue/green deployment is a deployment strategy in which you create two separate, but identical environments. One environment (blue) is running the current application version and one environment (green) is running the new application version.
How Blue Green deployment works in Kubernetes?
The blue/green deployment process works as follows: Deploy new version—deploy the new (green) version alongside the current (blue) version. Test it to ensure it works as expected, and deploy changes to it if needed. Switch over traffic—when the new version is ready, switch overall traffic from blue to green.

What is a load balancer Azure?
