To implement blue–green deployment, you create revisions of the container apps and assign traffic weights. The blue revision is assigned 100% of the traffic initially, while the green revision is deployed with no production traffic. After successful testing of the green revision, the traffic is switched over smoothly without downtime.
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same machine, there may be a single environment, but in industrial use, the development environment (where changes are originally made) and production ...
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.
Thus, simply changing the labels of the pods or changing the label selectors on the service can be used to control which pods get traffic and which don't, which can be used to support various deployment patterns like blue–green deployments or A/B testing. This capability to dynamically control how services utilize implementing resources ...
Continuous deployment (CD) is a software engineering approach in which software functionalities are delivered frequently and through automated deployments. [ 1 ] [ 2 ] [ 3 ]
There are several formal ITIL processes that are related to release management, primarily the release and deployment management process, which "aims to plan, schedule and control the movement of releases to test and live environments", [6] and the change enablement process. [7]
A best current practice, abbreviated as BCP, [1] is a de facto level of performance in engineering and information technology. It is more flexible than a standard , since techniques and tools are continually evolving.
