CD settings:
Users can consider multiple deployment strategies and variations for rolling out new versions of software in a continuous delivery process. 01Cloud provides four most commonly used methods in the CD process.
AB-Testing Deployment:
AB-Testing deployment is a method of comparing two or more versions of a software application or feature by presenting them to different groups of users simultaneously and analyzing their performance to determine which version yields better results.
Steps to use AB-testing deployment:
-
Navigate to CI/CD.
-
Go to settings and move to CD settings.
-
Select the type of AB-testing deployment.
-
Specify details for the analysis section by using Interval, Iterations and Threshold value
-
Select the type of Header from the dropdown.
-
To add another header, click on the Add Header button.
-
Click on the Save and click on yes to update the environment
Blue green Deployment:
Blue-green deployment is a strategy where the user has to maintain two identical production environments: one actively serving live traffic (blue), and the other inactive. When deploying updates, the user first deploys to the inactive environment (green), tests it thoroughly, and then switches traffic to green. This minimizes downtime and risk, as the user can quickly switch back to the blue environment if any issues arise. It’s like having a backup plan in place while updating the software seamlessly.
Steps to use Blue-green deployment:
-
Navigate to CI/CD.
-
Go to settings and move to CD settings.
-
Select the type of Blue-green deployment.
-
Specify details for the analysis section using Interval, Iterations and Threshold Value
-
Click on Save to update the environment.
-
Confirm the update by clicking on Yes.
Canary Deployment:
Canary deployment is the practice of making staged releases. We roll out a software update to a small part of the users first, so they may test it and provide feedback. Once the change is accepted, the update is rolled out to the rest of the users. The canary strategy offers no-downtime upgrades and easy rollbacks.
Steps to use canary deployment
-
Navigate to CI/CD.
-
Go to settings and move to CD settings.
-
Select the type of Canary deployment.
-
Specify details for the analysis section by analysing Interval, Max Weight, Step Weight and Threshold Value
-
Click on Save to update the environment.
Rolling Update:
Rolling update deployment is a method of updating software or applications in a staggered manner, where new versions are gradually deployed across different parts of the system while ensuring that the service remains available. It’s like updating a building floor by floor, allowing continuous operation with minimal disruption.
Steps to use rolling-update deployment:
-
Navigate to CI/CD.
-
Go to settings and move to CD settings.
-
Select the type of Rolling-update deployment.
-
Set the values for Max surge and Max unavailable.
-
Click on Save to update the environment.
-
Confirm the update by clicking on Yes.
