Canary Deployment (also known as canary deployment) is a software deployment technique used to implement new versions of an application in a production environment in a phased manner. This means that a new version can be deployed to several different environments at the same time, starting with a small portion of users, and then scaling up gradually to ensure that the new version works correctly. This technique is usually done in order to ensure that the new version works correctly before deploying it to all users.
Canary deployment is often used in production environments where downtime is not an option, such as real-time applications or critical services. This allows developers to test on a limited number of users, and then roll out to the rest of the users once the new version has been verified as safe. If the new release has problems, developers can stop the deployment and fix the problem without affecting all users.
Canary deployment can also be used to test new features before releasing them to the general public. This is especially useful for testing new features directly with real users, and then using this information to refine the feature before releasing it.
Canary deployment is a relatively straightforward process. The first step is to create a new version of the application. This version can be deployed on one or several servers according to the need. Once the new version is ready for use, a rule can be configured so that a limited portion of users receive the new version. This portion can vary from 5% to 25%, at the developer’s discretion. Once the new version has been tested with the selected users, the portion of users receiving the new version can be gradually increased until all users receive the new version.
In summary, canary deployment is a software deployment technique that allows developers to gradually deploy new versions of an application in a production environment. This is done to ensure that the new version works correctly before releasing it to all users. This technique can also be used to test new features directly with real users, and then improve the feature before releasing it. Canary deployment is a relatively simple process that allows developers to deploy new versions gradually to ensure the best performance of the application.
