Blue-Green deployment

At WebbyLab, we have clients for whom any downtime is a critical issue, so we use a deployment strategy that minimizes risks and downtime during software updates: the Blue-Green deployment.

The essence of Blue-Green deployment is that we have two identical environments: “blue” and “green”. The blue environment is where the current version of the software is running. The green environment is where we deploy the new version of the software.

Once the new version has been successfully tested in the green environment, we switch the traffic to it. This is done using a load balancer, which directs all requests from the blue environment to the green one.

Benefits of Blue-Green deployment:

• Seamless operation: Users experience no disruptions during software updates.
• Fast deployment: New software versions can be deployed quickly and without issues.
• Risk reduction: If the new version of the software has any problems, we can easily switch back to the old version without affecting users.
• Easy management: Blue-Green deployment is a straightforward and clear strategy that is easy to implement and manage.

Thanks to these benefits, Blue-Green deployment becomes a valuable tool that helps achieve seamless operation and fast software updates.
