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.
Rolling release development models are one of many types of software release life cycles.Although a rolling release model can be used in the development of any piece or collection of software, it is most often seen in use by Linux distributions, notable examples being GNU Guix System, Arch Linux, Gentoo Linux, openSUSE Tumbleweed, PCLinuxOS, Solus, SparkyLinux, and Void Linux.
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same machine, there may be a single environment, but in industrial use, the development environment (where changes are originally made) and production ...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 led to the creation of a unique, declarative configuration model that distinguished NixOS from other operating systems. [ 10 ] The NixOS Foundation was established in 2015 in the Netherlands to support projects that implement the purely functional deployment model, ensuring the ongoing development and sustainability of NixOS and its ecosystem.
A "hidden live" group can also be created within a production environment, consisting of servers that are not yet connected to the production load balancer, for the purposes of blue–green deployment. Deactivation Deactivation is the inverse of activation and refers to shutting down any already-executing components of a system.
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 ...

A deployment template is an unbound deployment plan which defines the steps of execution but not the profiles and systems. Deployment templates are patterns from which deployment plans can be created. Typical information captured for each step in the deployment plan is: Sequence Number; Activity Name; Activity Description; Scripted Instruction
