This means that while some of your users will still be served by the old environment, you won't even have full control on where your traffic is routed to. The problem with making changes in the DNS records will just result in a long traffic trail. Instead of going to the DNS records & making changes in DNS management interface, use load balancing. Keep in mind that while switching environments, make your domain to eventually point to different servers. Now that we know about the two environments of Blue-Green Deployment, let us look at some of the best practices to implement the same. While there might still be an issue with the lost transactions when the faulty environment was live, you could also design it in a way that both of your environments are fed with the transactions and one acts as a backup for the other one. Suppose if anything goes wrong with your latest release, you just have to switch back the router. Once you are ready to roll, all you have to do is switch the router so that all your traffic is directed towards your latest release & the other environment just goes idle.Īlso, Blue-Green deployment provides one of the most important features, a rapid rollback. And as you prepare for a new release, you do all your testing on the other environment which is not live. With two production environments (as identical as possible in nature), at any given point of time, one of them is live. This is exactly what blue-green deployment does. And this has to be taken care of quickly in order to minimize any sort of downtime. One of the major challenges with automating the deployment process is the cut-over itself, i.e moving the application from the final stage of testing to the live stage.
While the current version of the application is represented by the Blue environment, the green one is staged running a different version. With near zero downtime release and rollback capabilities, the fundamental idea of the Blue-Green Deployment is to shift the traffic between two identical environments that are running two different versions of the application. However, you also want to ensure that while this deployment is happening, a user can still look at your application, press a button or do whatever he wants, without your application going down! More like secretly deploying the "green version" while the "blue version" handles all the traffic in the meantime, before eventually swapping out the connections. the "green version" with some more goodies added, to be deployed. And then, there is a router that is used to route the traffic to the app. In a brief, there is a version of an application, lets call it "blue version" in production. What is Blue-Green Deployment?īlue-Green Deployment is a technique for releasing applications by shifting or moving the traffic between two identical environments running two different versions of an application. Discover more about blue green deployment & Drupal. Learn about why blue green deployment is the best strategy to reduce downtime and mitigate other risks involved in application deployment. Some sites actually lose thousands of dollars every minute they are down! Should deployment or upgrading your application be the real reason behind your loss? True that you can mitigate this with scheduled downtimes, but that is not something that will bring make the customers happy.

Having to take your application offline for updates or while launching a newer version is a daunting task and a real pain.
How much do you know about Blue Green Deployment? How is Blue Green Deployment in Drupal implemented? Blue Green Deployment is one of the mainstays of deployment strategies that conquers the limitations of traditional approach to application deployment.
