Rolling release, also known as rolling update or continuous delivery, is a concept in software development of frequently delivering updates to applications. [ 1 ] [ 2 ] [ 3 ] This is in contrast to a standard or point release development model which uses software versions which replace the previous version.
This also meant that typically, deployment schedules were now determined by the software supplier, not by the customers. Such flexibility led to the rise of continuous delivery as a viable option, especially for less risky web applications. Other options for software deployment include blue–green deployment and canary release deployment.
Continually deploy – Through a fully automated process, you can deploy and release any version of the software to any environment. According to Yan Cui, when it comes to serverless environments , ephemeral resources should be kept together and have their own deployment pipeline to achieve a high cohesion .
Continuous deployment (CD) is a software engineering approach in which software functionalities are delivered frequently and through automated deployments. [ 1 ] [ 2 ] [ 3 ]
By defining resources in a declarative format, Deployment Manager allows users to create, update, and delete resources as part of a blue–green deployment process. Like AWS CodeDeploy, it minimizes downtime by shifting traffic from the old to the new environment after performing necessary tests.
In software deployment, an environment or tier is a computer system or set of systems in which a computer program or software component is deployed and executed. In simple cases, such as developing and immediately executing a program on the same machine, there may be a single environment, but in industrial use, the development environment (where changes are originally made) and production ...
A canary release (or canary launch or canary deployment) allows developers to have features incrementally tested by a small set of developers. Feature flags like an alternate way to do canary launches [ 7 ] and allow targeting by geographic locations or even user attributes. [ 8 ]
